Where did the Xiongnu live?

The Xiongnu () were a confederation of nomadic peoples who, according to ancient Chinese sources, inhabited the eastern Asian Steppe from the 3rd century BC to the late 1st century AD. Chinese sources report that Modu Chanyu, the supreme leader after 209 BC, founded the Xiongnu Empire.

Xiongnu

After their previous overlords, the Yuezhi, migrated into Central Asia during the 2nd century BC, the Xiongnu became a dominant power on the steppes of north-east Central Asia, centred on an area known later as Mongolia. The Xiongnu were also active in areas now part of Siberia, Inner Mongolia, Gansu and Xinjiang. Their relations with adjacent Chinese dynasties to the south east were complex, with repeated periods of conflict and intrigue, alternating with exchanges of tribute, trade, and marriage treaties.

Attempts to identify the Xiongnu with later groups of the western Eurasian Steppe remain controversial. Scythians and Sarmatians were concurrently to the west. The identity of the ethnic core of Xiongnu has been a subject of varied hypotheses, because only a few words, mainly titles and personal names, were preserved in the Chinese sources. The name "Xiongnu" may be cognate with that of the Huns or the "Huna", although this is disputed. Other linguistic links – all of them also controversial – proposed by scholars include Iranian, Mongolic, Turkic, Uralic, Yeniseian, Tibeto-Burman or multi-ethnic.

An early reference to the Xiongnu was by the Han dynasty historian Sima Qian who wrote about the Xiongnu in the "Records of the Grand Historian" ( BC), drawing a distinct line between the settled Huaxia people (Chinese) to the pastoral nomads (Xiongnu), characterizing it as two polar groups in the sense of a civilization versus an uncivilized society: the Hua–Yi distinction. Pre-Han sources often classify the Xiongnu as a "Hu" people, which was a blanket term for nomadic people in general; it only became an ethnonym for the Xiongnu during the Han.

Ancient China often came in contact with the Xianyun and the Xirong nomadic peoples. In later Chinese historiography, some groups of these peoples were believed to be the possible progenitors of the Xiongnu people. These nomadic people often had repeated military confrontations with the Shang and especially the Zhou, who often conquered and enslaved the nomads in an expansion drift. During the Warring States period, the armies from the Qin, Zhao, and Yan states were encroaching and conquering various nomadic territories that were inhabited by the Xiongnu and other Hu peoples.

Sinologist Edwin Pulleyblank argued that the Xiongnu were part of a Xirong group called Yiqu, who had lived in Shaanbei and had been influenced by China for centuries, before they were driven out by the Qin dynasty. Qin's campaign against the Xiongnu expanded Qin's territory at the expense of the Xiongnu. In 215 BC, Qin Shi Huang sent General Meng Tian to conquer the Xiongnu and drive them from the Ordos Loop, which he did later that year. After the catastrophic defeat at the hands of Meng Tian, the Xiongnu leader Touman was forced to flee far into the Mongolian Plateau. The Qin empire became a threat to the Xiongnu, which ultimately led to the reorganization of the many tribes into a confederacy.In 209 BC, three years before the founding of Han China, the Xiongnu were brought together in a powerful confederation under a new chanyu, Modu Chanyu. This new political unity transformed them into a more formidable state by enabling formation of larger armies and the ability to exercise better strategic coordination. The Xiongnu adopted many of the Chinese agriculture techniques such as slave labor for heavy labor, wore silk like the Chinese, and lived in Chinese-style homes. The reason for creating the confederation remains unclear. Suggestions include the need for a stronger state to deal with the Qin unification of China that resulted in a loss of the Ordos region at the hands of Meng Tian or the political crisis that overtook the Xiongnu in 215 BC when Qin armies evicted them from their pastures on the Yellow River.

After forging internal unity, Modu expanded the empire on all sides. To the north he conquered a number of nomadic peoples, including the Dingling of southern Siberia. He crushed the power of the Donghu people of eastern Mongolia and Manchuria as well as the Yuezhi in the Hexi Corridor of Gansu, where his son, Jizhu, made a skull cup out of the Yuezhi king. Modu also reoccupied all the lands previously taken by the Qin general Meng Tian.

Under Modu's leadership, the Xiongnu threatened the Han dynasty, almost causing Emperor Gaozu, the first Han emperor, to lose his throne in 200 BC. By the time of Modu's death in 174 BC, the Xiongnu had driven the Yuezhi from the Hexi Corridor, killing the Yuezhi king in the process and asserting their presence in the Western Regions.

The Xiongnu were recognized as the most prominent of the nomads bordering the Chinese Han empire and during early relations between the Xiongnu and the Han, the former held the balance of power. According to the "Book of Han", later quoted in Duan Chengshi's ninth century "Miscellaneous Morsels from Youyang":

After Modu, later leaders formed a dualistic system of political organisation with the left and right branches of the Xiongnu divided on a regional basis. The "chanyu" or "shanyu", a ruler equivalent to the Emperor of China, exercised direct authority over the central territory. Longcheng (蘢城), near the Orkhon inscriptions in modern Mongolia, became the annual meeting place and served as the Xiongnu capital.

The ruler of the Xiongnu was called the Chanyu. Under him were the Tuqi Kings. The Tuqi King of the Left was normally the heir presumptive. Next lower in the hierarchy came more officials in pairs of left and right: the "guli", the army commanders, the great governors, the "dunghu" and the "gudu". Beneath them came the commanders of detachments of one thousand, of one hundred, and of ten men. This nation of nomads, a people on the march, was organized like an army.

Yap, apparently describing the early period, places the Chanyu's main camp north of Shanxi with the Tuqi King of the Left holding the area north of Beijing and the Tuqi King of the Right holding the Ordos Loop area as far as Gansu. Grousset, probably describing the situation after the Xiongnu had been driven north, places the Chanyu on the upper Orkhon River near where Genghis Khan would later establish his capital of Karakorum. The Tuqi King of the Left lived in the east, probably on the high Kherlen River. The Tuqi King of the Right lived in the west, perhaps near present-day Uliastai in the Khangai Mountains.

In the winter of 200 BC, following a siege of Taiyuan, Emperor Gaozu of Han personally led a military campaign against Modun. At the Battle of Baideng, he was ambushed reputedly by 300,000 elite Xiongnu cavalry. The emperor was cut off from supplies and reinforcements for seven days, only narrowly escaping capture.

The Han Chinese sent princesses to marry Xiongnu leaders in their efforts to stop the border raids. Along with arranged marriages, the Han sent gifts to bribe the Xiongnu to stop attacking. After the defeat at Pingcheng, the Han emperor abandoned a military solution to the Xiongnu threat. Instead, in 198BC, the courtier was dispatched for negotiations. The peace settlement eventually reached between the parties included a Han princess given in marriage to the "chanyu" (called "heqin" ); periodic gifts to the Xiongnu of silk, distilled beverages and rice; equal status between the states; and the Great Wall as mutual border.

This first treaty set the pattern for relations between the Han and the Xiongnu for sixty years. Up to 135 BC, the treaty was renewed nine times, each time with an increase in the "gifts". In 192 BC, Modun even asked for the hand of Emperor Gao's widow Empress Lü Zhi. His son and successor, the energetic Jiyu, known as the Laoshang Chanyu, continued his father's expansionist policies. Laoshang succeeded in negotiating with Emperor Wen terms for the maintenance of a large scale government sponsored market system.

While the Xiongnu benefited handsomely, from the Chinese perspective marriage treaties were costly, humiliating, and ineffective. Laoshang showed that he did not take the peace treaty seriously. On one occasion his scouts penetrated to a point near Chang'an. In 166 BC he personally led 140,000 cavalry to invade Anding, reaching as far as the imperial retreat at Yong. In 158 BC, his successor sent 30,000 cavalry to attack Shangdang and another 30,000 to Yunzhong.

The Xiongnu also practiced marriage alliances with Han dynasty officers and officials who defected to their side. The older sister of the Chanyu (the Xiongnu ruler) was married to the Xiongnu General Zhao Xin, the Marquis of Xi who was serving the Han dynasty. The daughter of the Chanyu was married to the Han Chinese General Li Ling after he surrendered and defected. The Yenisei Kirghiz Khagans claimed descent from Li Ling. Another Han Chinese General who defected to the Xiongnu was Li Guangli who also married a daughter of the Chanyu.

When the Eastern Jin dynasty ended the Xianbei Northern Wei received the Han Chinese Jin prince Sima Chuzhi 司馬楚之 as a refugee. A Northern Wei Xianbei Princess married Sima Chuzhi, giving birth to Sima Jinlong 司馬金龍. Northern Liang Xiongnu King Juqu Mujian's daughter married Sima Jinlong.

The Han dynasty made preparations for war when the Han Emperor Wu dispatched the explorer Zhang Qian to explore the mysterious kingdoms to the west and to form an alliance with the Yuezhi people in order to combat the Xiongnu. During this time Zhang married a Xiongnu wife, who bore him a son, and gained the trust of the Xiongnu leader. While Zhang Qian did not succeed in this mission, his reports of the west provided even greater incentive to counter the Xiongnu hold on westward routes out of China, and the Chinese prepared to mount a large scale attack using the Northern Silk Road to move men and material.

While Han China was making preparations for a military confrontation from the reign of Emperor Wen, the break did not come until 133 BC, following an abortive trap to ambush the "chanyu" at Mayi. By that point the empire was consolidated politically, militarily and economically, and was led by an adventurous pro-war faction at court. In that year, Emperor Wu reversed the decision he had made the year before to renew the peace treaty.

Full-scale war broke out in autumn 129 BC, when 40,000 Chinese cavalry made a surprise attack on the Xiongnu at the border markets. In 127 BC, the Han general Wei Qing retook the Ordos. In 121 BC, the Xiongnu suffered another setback when Huo Qubing led a force of light cavalry westward out of Longxi and within six days fought his way through five Xiongnu kingdoms. The Xiongnu Hunye king was forced to surrender with 40,000 men. In 119 BC both Huo and Wei, each leading 50,000 cavalrymen and 100,000 footsoldiers (in order to keep up with the mobility of the Xiongnu, many of the non-cavalry Han soldiers were mobile infantrymen who traveled on horseback but fought on foot), and advancing along different routes, forced the "chanyu" and his court to flee north of the Gobi Desert. Major logistical difficulties limited the duration and long-term continuation of these campaigns. According to the analysis of Yan You (嚴尤), the difficulties were twofold. Firstly there was the problem of supplying food across long distances. Secondly, the weather in the northern Xiongnu lands was difficult for Han soldiers, who could never carry enough fuel. According to official reports, the Xiongnu lost 80,000 to 90,000 men, and out of the 140,000 horses the Han forces had brought into the desert, fewer than 30,000 returned to China.

As a result of these battles, the Chinese controlled the strategic region from the Ordos and Gansu corridor to Lop Nor. They succeeded in separating the Xiongnu from the Qiang peoples to the south, and also gained direct access to the Western Regions. Because of strong Chinese control over the Xiongnu, the Xiongnu became unstable and were no longer a threat to the Han Chinese.
Ban Chao, Protector General (都護; "Duhu") of the Han dynasty, embarked with an army of 70,000 men in a campaign against the Xiongnu insurgents who were harassing the trade route now known as the Silk Road. His successful military campaign saw the subjugation of one Xiongnu tribe after another. Ban Chao also sent an envoy named Gan Ying to Daqin (Rome). Ban Chao was created the Marquess of Dingyuan (定遠侯, i.e., "the Marquess who stabilized faraway places") for his services to the Han Empire and returned to the capital Luoyang at the age of 70 years and died there in the year 102. Following his death, the power of the Xiongnu in the Western Regions increased again, and the emperors of subsequent dynasties were never again able to reach so far to the west.

When a Chanyu died, power could pass to his younger brother if his son was not of age. This system, which can be compared to Gaelic tanistry, normally kept an adult male on the throne, but could cause trouble in later generations when there were several lineages that might claim the throne. When the 12th Chanyu died in 60 BC, power was taken by Woyanqudi, a grandson of the 12th Chanyu's cousin. Being something of a usurper, he tried to put his own men in power, which only increased the number of his enemies. The 12th Chanyu's son fled east and, in 58 BC, revolted. Few would support Woyanqudi and he was driven to suicide, leaving the rebel son, Huhanye, as the 14th Chanyu. The Woyanqudi faction then set up his brother, Tuqi, as Chanyu (58 BC). In 57 BC three more men declared themselves Chanyu. Two dropped their claims in favor of the third who was defeated by Tuqi in that year and surrendered to Huhanye the following year. In 56 BC Tuqi was defeated by Huhanye and committed suicide, but two more claimants appeared: Runzhen and Huhanye's elder brother Zhizhi Chanyu. Runzhen was killed by Zhizhi in 54 BC, leaving only Zhizhi and Huhanye. Zhizhi grew in power, and, in 53 BC, Huhanye moved south and submitted to the Chinese. Huhanye used Chinese support to weaken Zhizhi, who gradually moved west. In 49 BC, a brother to Tuqi set himself up as Chanyu and was killed by Zhizhi. In 36 BC, Zhizhi was killed by a Chinese army while trying to establish a new kingdom in the far west near Lake Balkhash.

In 53 BC Huhanye (呼韓邪) decided to enter into tributary relations with Han China. The original terms insisted on by the Han court were that, first, the "chanyu" or his representatives should come to the capital to pay homage; secondly, the "chanyu" should send a hostage prince; and thirdly, the "chanyu" should present tribute to the Han emperor. The political status of the Xiongnu in the Chinese world order was reduced from that of a "brotherly state" to that of an "outer vassal" (外臣). During this period, however, the Xiongnu maintained political sovereignty and full territorial integrity. The Great Wall of China continued to serve as the line of demarcation between Han and Xiongnu.

Huhanye sent his son, the "wise king of the right" Shuloujutang, to the Han court as hostage. In 51 BC he personally visited Chang'an to pay homage to the emperor on the Lunar New Year. In the same year, another envoy Qijushan (稽居狦) was received at the Sweet Spring Palace in the north west of modern Shanxi. On the financial side, Huhanye was amply rewarded in large quantities of gold, cash, clothes, silk, horses and grain for his participation. Huhanye made two further homage trips, in 49 BC and 33 BC; with each one the imperial gifts were increased. On the last trip, Huhanye took the opportunity to ask to be allowed to become an imperial son-in-law. As a sign of the decline in the political status of the Xiongnu, Emperor Yuan refused, giving him instead five ladies-in-waiting. One of them was Wang Zhaojun, famed in Chinese folklore as one of the Four Beauties.

When Zhizhi learned of his brother's submission, he also sent a son to the Han court as hostage in 53 BC. Then twice, in 51 BC and 50 BC, he sent envoys to the Han court with tribute. But having failed to pay homage personally, he was never admitted to the tributary system. In 36 BC, a junior officer named Chen Tang, with the help of Gan Yanshou, protector-general of the Western Regions, assembled an expeditionary force that defeated him at the Battle of Zhizhi and sent his head as a trophy to Chang'an.

Tributary relations were discontinued during the reign of Huduershi (18 AD–48), corresponding to the political upheavals of the Xin Dynasty in China. The Xiongnu took the opportunity to regain control of the western regions, as well as neighbouring peoples such as the Wuhuan. In 24 AD, Hudershi even talked about reversing the tributary system.

The Xiongnu's new power was met with a policy of appeasement by Emperor Guangwu. At the height of his power, Huduershi even compared himself to his illustrious ancestor, Modu. Due to growing regionalism among the Xiongnu, however, Huduershi was never able to establish unquestioned authority. In contravention of a principle of fraternal succession established by Huhanye, Huduershi designated his son Punu as heir-apparent. However, as the eldest son of the preceding "chanyu", Bi (Pi) – the Rizhu King of the Right – had a more legitimate claim. Consequently, Bi refused to attend the annual meeting at the "chanyu"'s court. Nevertheless, in 46 AD, Punu ascended the throne.

In 48 AD, a confederation of eight Xiongnu tribes in Bi's power base in the south, with a military force totalling 40,000 to 50,000 men, seceded from Punu's kingdom and acclaimed Bi as "chanyu". This kingdom became known as the Southern Xiongnu.

The rump kingdom under Punu, around the Orkhon (modern north central Mongolia) became known as the Northern Xiongnu. Punu, who became known as the Northern "Chanyu", began to put military pressure on the Southern Xiongnu.

In 49 AD, Tsi Yung, a Han governor of Liaodong, allied with the Wuhuan and Xianbei, attacked the Northern Xiongnu.
The Northern Xiongnu suffered two major defeats: one at the hands of the Xianbei in 85 AD, and by the Han during the Battle of Ikh Bayan, in 89 AD. The northern "chanyu" fled to the north-west with his subjects.

In about 155 AD, the Northern Xiongnu were decisively "crushed and subjugated" by the Xianbei.

Coincidentally, the Southern Xiongnu were plagued by natural disasters and misfortunes – in addition to the threat posed by Punu. Consequently, in 50 AD, the Southern Xiongnu submitted to tributary relations with Han China. The system of tribute was considerably tightened by the Han, to keep the Southern Xiongnu under control. The "chanyu" was ordered to establish his court in the Meiji district of Xihe commandery and the Southern Xiongnu were resettled in eight frontier commanderies. At the same time, large numbers of Chinese were also resettled in these commanderies, in mixed Han-Xiongnu settlements.
Economically, the Southern Xiongnu became reliant on trade with the Han.

Tensions were evident between Han settlers and practitioners of the nomadic way of life. Thus, in 94, Anguo Chanyu joined forces with newly subjugated Xiongnu from the north and started a large scale rebellion against the Han.

During the late 2nd century AD, the southern Xiongnu were drawn into the rebellions then plaguing the Han court. In 188, the "chanyu" was murdered by some of his own subjects for agreeing to send troops to help the Han suppress a rebellion in Hebei – many of the Xiongnu feared that it would set a precedent for unending military service to the Han court. The murdered "chanyu's" son Yufuluo, entitled Chizhisizhu (), succeeded him, but was then overthrown by the same rebellious faction in 189. He travelled to Luoyang (the Han capital) to seek aid from the Han court, but at this time the Han court was in disorder from the clash between Grand General He Jin and the eunuchs, and the intervention of the warlord Dong Zhuo. The "chanyu" had no choice but to settle down with his followers in Pingyang, a city in Shanxi. In 195, he died and was succeeded as "chanyu" by his brother Huchuquan Chanyu.

In 215–216 AD, the warlord-statesman Cao Cao detained Huchuquan Chanyu in the city of Ye, and divided his followers in Shanxi into five divisions: left, right, south, north, and centre. This was aimed at preventing the exiled Xiongnu in Shanxi from engaging in rebellion, and also allowed Cao Cao to use the Xiongnu as auxiliaries in his cavalry.

Later the Xiongnu aristocracy in Shanxi changed their surname from Luanti to Liu for prestige reasons, claiming that they were related to the Han imperial clan through the old intermarriage policy.
After Huchuquan, the Southern Xiongnu were partitioned into five local tribes. Each local chief was under the "surveillance of a chinese resident", while the shanyu was in "semicaptivity at the imperial court."

In 304, Liu Yuan became Chanyu of the Five Hordes. In 308, declared himself emperor and founded the Han Zhao Dynasty. In 311, his son and successor Liu Cong captured Luoyang, and with it the Emperor Huai of Jin China.

In 316, the Emperor Min of Jin China was captured in Chang'an. Both emperors were humiliated as cupbearers in Linfen before being executed in 313 and 318.

North China came under Xiongnu rule while the remnants of the Jin dynasty survived in the south at Jiankang.

In 318, after suppressing a coup by a powerful minister in the Xiongnu-Han court, in which the emperor and a large proportion of the aristocracy were massacred), the Xiongnu prince Liu Yao moved the Xiongnu-Han capital from Pingyang to Chang'an and renamed the dynasty as Zhao (Liu Yuan had declared the empire's name Han to create a linkage with Han Dynasty—to which he claimed he was a descendant, through a princess, but Liu Yao felt that it was time to end the linkage with Han and explicitly restore the linkage to the great Xiongnu chanyu Maodun, and therefore decided to change the name of the state. (However, this was not a break from Liu Yuan, as he continued to honor Liu Yuan and Liu Cong posthumously; it is hence known to historians collectively as Han Zhao).

However, the eastern part of north China came under the control of a rebel Xiongnu-Han general of Jie ancestry named Shi Le. Liu Yao and Shi Le fought a long war until 329, when Liu Yao was captured in battle and executed. Chang'an fell to Shi Le soon after, and the Xiongnu dynasty was wiped out. North China was ruled by Shi Le's Later Zhao dynasty for the next 20 years.

However, the "Liu" Xiongnu remained active in the north for at least another century.

The northern Tiefu branch of the Xiongnu gained control of the Inner Mongolian region in the 10 years between the conquest of the Tuoba Xianbei state of Dai by the Former Qin empire in 376, and its restoration in 386 as the Northern Wei. After 386, the Tiefu were gradually destroyed by or surrendered to the Tuoba, with the submitting Tiefu becoming known as the Dugu. Liu Bobo, a surviving prince of the Tiefu fled to the Ordos Loop, where he founded a state called the Xia (thus named because of the Xiongnu's supposed ancestry from the Xia dynasty) and changed his surname to Helian (赫連). The Helian-Xia state was conquered by the Northern Wei in 428–31, and the Xiongnu thenceforth effectively ceased to play a major role in Chinese history, assimilating into the Xianbei and Han ethnicities.

Tongwancheng (meaning "Unite All Nations") was the capital of the Xia (Sixteen Kingdoms), whose rulers claimed descent from Modu Chanyu.

The ruined city was discovered in 1996 and the State Council designated it as a cultural relic under top state protection. The repair of the Yong'an Platform, where Helian Bobo, emperor of the Da Xia regime, reviewed parading troops, has been finished and restoration on the 31-meter-tall turret follows.

The Juqu were a branch of the Xiongnu. Their leader Juqu Mengxun took over the Northern Liang by overthrowing the former puppet ruler Duan Ye. By 439, the Juqu power was destroyed by the Northern Wei. Their remnants were then settled in the city of Gaochang before being destroyed by the Rouran.

Barfield attempted to interpret Xiongnu history as well as narrate it. He made the following points: The Xiongnu confederation was unusually long-lived for a steppe empire. The purpose of raiding China was not simply for goods, but to force the Chinese to pay regular tribute. The power of the Xiongnu ruler was based on his control of Chinese tribute which he used to reward his supporters. The Han and Xiongnu empires rose at the same time because the Xiongnu state depended on Chinese tribute. A major Xiongnu weakness was the custom of lateral succession. If a dead ruler's son was not old enough to take command, power passed to the late ruler's brother. This worked in the first generation but could lead to civil war in the second generation. The first time this happened, in 60 BC, the weaker party adopted what Barfield calls the 'inner frontier strategy.' They moved south and submitted to China and then used Chinese resources to defeat the Northern Xiongnu and re-establish the empire. The second time this happened, about 47 AD, the strategy failed. The southern ruler was unable to defeat the northern ruler and the Xiongnu remained divided.

The sound of the first Chinese character (匈) has been reconstructed as in Old Chinese. The Chinese name for the Xiongnu was a pejorative term in itself, as the characters have the meaning of "fierce slave". The Chinese characters are pronounced as "Xiōngnú" in modern Mandarin Chinese.

The supposed Old Chinese sound of the first character (匈) has a possible similarity with the name "Hun" in European languages. The second character (奴) appears to have no parallel in Western terminology. Whether the similarity is evidence of kinship or mere coincidence is hard to tell. It could lend credence to the theory that the Huns were in fact descendants of the Northern Xiongnu who migrated westward, or that the Huns were using a name borrowed from the Northern Xiongnu, or that these Xiongnu made up part of the Hun confederation.

The Xiongnu-Hun hypothesis originated with the 18th-century French historian Joseph de Guignes, who noticed that ancient Chinese scholars had referred to members of tribes associated with the Xiongnu by names similar to "Hun", albeit with varying Chinese characters. Étienne de la Vaissière has shown that, in the Sogdian script used in the so-called "Sogdian Ancient Letters", both the Xiongnu and Huns were referred to as γwn ("xwn"), indicating that the two were synonymous. Although the theory that the Xiongnu were precursors of the Huns known later in Europe is now accepted by many scholars, it has yet to become a consensus view. The identification with the Huns may be either incorrect or an oversimplification (as would appear to be the case with a proto-Mongol people, the Rouran, who have sometimes been linked to the Avars of Central Europe).

Harold Walter Bailey proposed an Iranian origin of the Xiongnu, recognizing all the earliest Xiongnu names of the 2nd century BC as being of the Iranian type. This theory is supported by turkologist. Central Asian scholar Christopher I. Beckwith notes that the Xiongnu name could be a cognate of Scythian, Saka and Sogdia, corresponding to a name for Northern Iranians. According to Beckwith the Xiongnu could have contained a leading Iranian component when they started out, but more likely they had earlier been subjects of an Iranian people and learned from them the Iranian nomadic model.

In the UNESCO-published "History of Civilizations of Central Asia", its editor János Harmatta concludes that the royal tribes and kings of the Xiongnu bore Iranian names, that all Xiongnu words noted by the Chinese can be explained from a Scythian language, and that it is therefore clear that the majority of Hsiung-nu tribes spoke an Eastern Iranian language.

Mongolian and other scholars have suggested that the Xiongnu spoke a language related to the Mongolic languages. Mongolian archaeologists proposed that the Slab Grave Culture people were the ancestors of the Xiongnu, and some scholars have suggested that the Xiongnu may have been the ancestors of the Mongols. According to the "Book of Song", (section Joujan), Joujan's (Rouran Khaganate) alternative name was "Tatar" or "Tartar" and they were a Xiongnu tribe". Nikita Bichurin considered Xiongnu and Xianbei to be two subgroups (or dynasties) but the same ethnicity.

Genghis Khan refers to the time of Modu Chanyu as "the remote times of our Chanyu" in his letter to Daoist Qiu Chuji. Sun and moon symbol of Xiongnu that discovered by archaeologists is similar to Mongolian Soyombo symbol.

Proponents of a Turkic language theory include E.H. Parker, Jean-Pierre Abel-Rémusat, Julius Klaproth, Kurakichi Shiratori, Gustaf John Ramstedt, Annemarie von Gabain, and Omeljan Pritsak. Some sources say the ruling class was proto-Turkic, while others suggest it was proto-Hun. Craig Benjamin sees the Xiongnu as either proto-Turks or proto-Mongols who possibly spoke a language related to the Dingling.

Both the 7th-century Chinese "History of the Northern Dynasties" and the "Book of Zhou", an inscription in the Sogdian language, report the Turks to be a subgroup of the Huns.

Lajos Ligeti was the first to suggest that the Xiongnu spoke a Yeniseian language. In the early 1960s Edwin Pulleyblank was the first to expand upon this idea with credible evidence. In 2000, Alexander Vovin reanalyzed Pulleyblank's argument and found further support for it by utilizing the most recent reconstruction of Old Chinese phonology by Starostin and Baxter and a single Chinese transcription of a sentence in the language of the Jie people, a member tribe of the Xiongnu Confederacy. Previous Turkic interpretations of the aforementioned sentence do not match the Chinese translation as precisely as using Yeniseian grammar. Pulleybank and D. N. Keightley asserted that the Xiongnu titles "were originally Siberian words but were later borrowed by the Turkic and Mongolic peoples". The Xiongnu language gave to the later Turkic and Mongolian empires a number of important culture words including Turkish tängri, Mongolian tenggeri, was originally the Xiongnu word for “heaven”, chengli (tháːŋ-wrə́j). Titles such as tarqan and tegin and kaghan were also inherited from the Xiongnu language.

Since the early 19th century, a number of Western scholars have proposed a connection between various language families or subfamilies and the language or languages of the Xiongnu. Albert Terrien de Lacouperie considered them to be multi-component groups. Many scholars believe the Xiongnu confederation was a mixture of different ethno-linguistic groups, and that their main language (as represented in the Chinese sources) and its relationships have not yet been satisfactorily determined. Kim rejects "old racial theories or even ethnic affiliations" in favour of the "historical reality of these extensive, multiethnic, polyglot steppe empires".

Chinese sources link the Tiele people and Ashina to the Xiongnu, not all Turkic peoples. According to the "Book of Zhou" and the "History of the Northern Dynasties", the Ashina clan was a component of the Xiongnu confederation, but this connection is disputed, and according to the "Book of Sui" and the "Tongdian", they were "mixed nomads" () from Pingliang. The Ashina and Tiele may have been separate ethnic groups who mixed with the Xiongnu. Indeed, Chinese sources link many nomadic peoples ("hu"; see "Wu Hu") on their northern borders to the Xiongnu, just as Greco-Roman historiographers called Avars and Huns "Scythians". The Greek cognate of "Tourkia" () was used by the Byzantine emperor and scholar Constantine VII Porphyrogenitus in his book "De Administrando Imperio", though in his use, "Turks" always referred to Magyars. Such archaizing was a common literary "topos", and implied similar geographic origins and nomadic lifestyle but not direct filiation. Some Uyghurs claimed descent from the Xiongnu (according to Chinese history "Weishu", the founder of the Uyghur Khaganate was descended from a Xiongnu ruler), but many contemporary scholars do not consider the modern Uyghurs to be of direct linear descent from the old Uyghur Khaganate because modern Uyghur language and Old Uyghur languages are different. Rather, they consider them to be descendants of a number of people, one of them the ancient Uyghurs.

The Turkologist Gerhard Doerfer has denied any possibility of a relationship between the Xiongnu language and any other known language and rejected in the strongest terms any connection with Turkic or Mongolian.

The original geographic location of the Xiongnu is disputed among steppe archaeologists. Since the 1960s, the geographic origin of the Xiongnu has attempted to be traced through an analysis of Early Iron Age burial constructions. No region has been proven to have mortuary practices that clearly match that of the Xiongnu.

The political center of the Xiongnu state was in Mongolia and almost all of the Xiongnu kings were buried in Mongolia.

In the 1920s, Pyotr Kozlov's excavations of the royal tombs at the Noin-Ula burial site in northern Mongolia that date to around the first century CE provided a glimpse into the lost world of the Xiongnu. Other archaeological sites have been unearthed in Inner Mongolia and elsewhere; they represent the Neolithic and historical periods of the Xiongnu's history. Those included the Ordos culture, many of them had been identified as the Xiongnu cultures. The region was occupied predominantly by peoples showing Mongoloid features, known from their skeletal remains and artifacts. Portraits found in the Noin-Ula excavations demonstrate other cultural evidences and influences, showing that Chinese and Xiongnu art have influenced each other mutually. Some of these embroidered portraits in the Noin-Ula kurgans also depict the Xiongnu with long braided hair with wide ribbons, which is seen to be identical with the Ashina clan hair-style. Well-preserved bodies in Xiongnu and pre-Xiongnu tombs in the Mongolian Republic and southern Siberia show both Mongoloid and Caucasian features. Analysis of skeletal remains from sites attributed to the Xiongnu provides an identification of dolichocephalic Mongoloid, ethnically distinct from neighboring populations in present-day Mongolia. Russian and Chinese anthropological and craniofacial studies show that the Xiongnu were physically very heterogenous, with six different population clusters showing different degrees of Mongoloid and Caucasoid physical traits. These clusters point to significant cross-regional migrations (both east to west and west to east) that likely started in the Neolithic period and continued to the medieval Mongolian period.

Presently, there exist four fully excavated and well documented cemeteries: Ivolga, Dyrestui, Burkhan Tolgoi, and Daodunzi. Additionally thousands of tombs have been recorded in Transbaikalia and Mongolia. In addition to these, the Tamir 1 excavation site from a 2005 Silkroad Arkanghai Excavation Project is the only Xiongnu cemetery in Mongolia to be fully mapped in scale. Tamir 1 was located on Tamiryn Ulaan Khoshuu, a prominent granitic outcrop near other cemeteries of the Neolithic, Bronze Age, and Mongol periods. Important finds at the site included a lacquer bowl, glass beads, and three TLV mirrors. Archaeologists from this project believe that these artifacts paired with the general richness and size of the graves suggests that this cemetery was for more important or wealthy Xiongnu individuals. The TLV mirrors are of particular interest. Three mirrors were acquired from three different graves at the site. The mirror found at feature 160 is believed to be a low-quality, local imitation of a Han mirror, while the whole mirror found at feature 100 and fragments of a mirror found at feature 109 are believed to belong to the classical TLV mirrors and date back to the Xin Dynasty or the early to middle Eastern Han period. The archaeologists have chosen to, for the most part, refrain from positing anything about Han-Xiongnu relations based on these particular mirrors. However, they were willing to mention the following: "There is no clear indication of the ethnicity of this tomb occupant, but in a similar brick-chambered tomb of late Eastern Han period at the same cemetery, archaeologists discovered a bronze seal with the official title that the Han government bestowed upon the leader of the Xiongnu. The excavators suggested that these brick chamber tombs all belong to the Xiongnu (Qinghai 1993)."

Classifications of these burial sites make distinction between two prevailing type of burials: "(1). monumental ramped terrace tombs which are often flanked by smaller "satellite" burials and (2) 'circular' or 'ring' burials." Some scholars consider this a division between "elite" graves and "commoner" graves. Other scholars, find this division too simplistic and not evocative of a true distinction because it shows "ignorance of the nature of the mortuary investments and typically luxuriant burial assemblages [and does not account for] the discovery of other lesser interments that do not qualify as either of these types."

A majority (89%) of Xiongnu mitochondrial sequences from the Egyin Gol Valley can be classified as belonging to Asian haplogroups, and nearly 11% belong to European mitochondrial haplogroups.

Over the past decade, Chinese archaeologists have published several reviews regarding the results of excavations in Xinjiang. They imply the Xiongnu's supreme ruling class. Particularly interesting are the tombs in the cemetery at Heigouliang, Xinjiang (the Black Gouliang cemetery, also known as the summer palace of the Xiongnu king), east of the Barkol basin, near the city of Hami. By typing results of DNA samples during the excavation of one of the tombs, it was determined that of the 12 men: 6 Q1a* (not Q1a1-M120, not Q1a1b-M25, not Q1a2-M3), 4 Q1b-M378, 2 Q* (not Q1a, not Q1b: unable to determine subclades):

Within the Xiongnu culture more variety is visible from site to site than from "era" to "era," in terms of the Chinese chronology, yet all form a whole that is distinct from that of the Han and other peoples of the non-Chinese north. In some instances iconography can not be used as the main cultural identifier because art depicting animal predation is common among the steppe peoples. An example of animal predation associated with Xiongnu culture is a tiger carrying dead prey. We see a similar image in work from Maoqinggou, a site which is presumed to have been under Xiongnu political control but is still clearly non-Xiongnu. From Maoqinggou, we see the prey replaced by an extension of the tiger's foot. The work also depicts a lower level of execution; Maoqinggou work was executed in a rounder, less detailed style. In its broadest sense, Xiongnu iconography of animal predation include examples such as the gold headdress from Aluchaideng and gold earrings with a turquoise and jade inlay discovered in Xigouban, Inner Mongolia. The gold headdress can be viewed, along with some other examples of Xiongnu art, from the external links at the bottom of this article.

Xiongnu art is harder to distinguish from Saka or Scythian art. There was a similarity present in stylistic execution, but Xiongnu art and Saka art did often differ in terms of iconography. Saka art does not appear to have included predation scenes, especially with dead prey, or same-animal combat. Additionally, Saka art included elements not common to Xiongnu iconography, such as a winged, horned horse. The two cultures also used two different bird heads. Xiongnu depictions of birds have a tendency to have a moderate eye and beak and have ears, while Saka birds have a pronounced eye and beak and no ears. Some scholars claim these differences are indicative of cultural differences. Scholar Sophia-Karin Psarras claims that Xiongnu images of animal predation, specifically tiger plus prey, is spiritual, representative of death and rebirth, and same-animal combat is representative of the acquisition of or maintenance of power.

The rock art of the Yin and Helan Mountains is dated from the 9th millennium BC to the 19th century AD. It consists mainly of engraved signs (petroglyphs) and only minimally of painted images.

Excavations conducted between 1924 and 1925 in the Noin-Ula kurgans produced objects with over twenty carved characters, which were either identical or very similar to that of to the runic letters of the Old Turkic alphabet discovered in the Orkhon Valley. From this a some scholars hold that the Xiongnu had a script similar to Eurasian runiform and this alphabet itself served as the basis for the ancient Turkic writing.

The "Records of the Grand Historian" (vol. ) state that when the Xiongnu noted down something or transmitted a message, they made cuts on a piece of wood; they also mention a "Hu script".
Xiongnu were a nomadic people. From their lifestyle of herding flocks and their horse-trade with China, we can conclude that their diet consist mainly of mutton, horse meat and wild geese that were shot down.

In various kinds of ancient inscriptions on monuments of Munmu of Silla, it is recorded that King Silla came from Xiongnu. Also, there are some Korean researchers point out grave goods of Silla and Xiongnu are alike and also some researchers propose that Silla King is descended from Xiongnu. The Korean traditional cloth Hanbok shows some Iranian influence. The royal Crowns of Silla are identical to Persian Crowns found in today Afghanistan. About this, the Korean public broadcaster KBS has reported a documentary.

Xiongnu

The Xiongnu () were a confederation of nomadic peoples who, according to ancient Chinese sources, inhabited the eastern Asian Steppe from the 3rd century BC to the late 1st century AD. Chinese sources report that Modu Chanyu, the supreme leader after 209 BC, founded the Xiongnu Empire.

After their previous overlords, the Yuezhi, migrated into Central Asia during the 2nd century BC, the Xiongnu became a dominant power on the steppes of north-east Central Asia, centred on an area known later as Mongolia. The Xiongnu were also active in areas now part of Siberia, Inner Mongolia, Gansu and Xinjiang. Their relations with adjacent Chinese dynasties to the south east were complex, with repeated periods of conflict and intrigue, alternating with exchanges of tribute, trade, and marriage treaties.

Attempts to identify the Xiongnu with later groups of the western Eurasian Steppe remain controversial. Scythians and Sarmatians were concurrently to the west. The identity of the ethnic core of Xiongnu has been a subject of varied hypotheses, because only a few words, mainly titles and personal names, were preserved in the Chinese sources. The name "Xiongnu" may be cognate with that of the Huns or the "Huna", although this is disputed. Other linguistic links – all of them also controversial – proposed by scholars include Iranian, Mongolic, Turkic, Uralic, Yeniseian, Tibeto-Burman or multi-ethnic.

An early reference to the Xiongnu was by the Han dynasty historian Sima Qian who wrote about the Xiongnu in the "Records of the Grand Historian" ( BC), drawing a distinct line between the settled Huaxia people (Chinese) to the pastoral nomads (Xiongnu), characterizing it as two polar groups in the sense of a civilization versus an uncivilized society: the Hua–Yi distinction. Pre-Han sources often classify the Xiongnu as a "Hu" people, which was a blanket term for nomadic people in general; it only became an ethnonym for the Xiongnu during the Han.

Ancient China often came in contact with the Xianyun and the Xirong nomadic peoples. In later Chinese historiography, some groups of these peoples were believed to be the possible progenitors of the Xiongnu people. These nomadic people often had repeated military confrontations with the Shang and especially the Zhou, who often conquered and enslaved the nomads in an expansion drift. During the Warring States period, the armies from the Qin, Zhao, and Yan states were encroaching and conquering various nomadic territories that were inhabited by the Xiongnu and other Hu peoples.

After forging internal unity, Modu expanded the empire on all sides. To the north he conquered a number of nomadic peoples, including the Dingling of southern Siberia. He crushed the power of the Donghu people of eastern Mongolia and Manchuria as well as the Yuezhi in the Hexi Corridor of Gansu, where his son, Jizhu, made a skull cup out of the Yuezhi king. Modu also reoccupied all the lands previously taken by the Qin general Meng Tian.

Under Modu's leadership, the Xiongnu threatened the Han dynasty, almost causing Emperor Gaozu, the first Han emperor, to lose his throne in 200 BC. By the time of Modu's death in 174 BC, the Xiongnu had driven the Yuezhi from the Hexi Corridor, killing the Yuezhi king in the process and asserting their presence in the Western Regions.

The Xiongnu were recognized as the most prominent of the nomads bordering the Chinese Han empire and during early relations between the Xiongnu and the Han, the former held the balance of power. According to the "Book of Han", later quoted in Duan Chengshi's ninth century "Miscellaneous Morsels from Youyang":

After Modu, later leaders formed a dualistic system of political organisation with the left and right branches of the Xiongnu divided on a regional basis. The "chanyu" or "shanyu", a ruler equivalent to the Emperor of China, exercised direct authority over the central territory. Longcheng (蘢城), near the Orkhon inscriptions in modern Mongolia, became the annual meeting place and served as the Xiongnu capital.

The ruler of the Xiongnu was called the Chanyu. Under him were the Tuqi Kings. The Tuqi King of the Left was normally the heir presumptive. Next lower in the hierarchy came more officials in pairs of left and right: the "guli", the army commanders, the great governors, the "dunghu" and the "gudu". Beneath them came the commanders of detachments of one thousand, of one hundred, and of ten men. This nation of nomads, a people on the march, was organized like an army.

Yap, apparently describing the early period, places the Chanyu's main camp north of Shanxi with the Tuqi King of the Left holding the area north of Beijing and the Tuqi King of the Right holding the Ordos Loop area as far as Gansu. Grousset, probably describing the situation after the Xiongnu had been driven north, places the Chanyu on the upper Orkhon River near where Genghis Khan would later establish his capital of Karakorum. The Tuqi King of the Left lived in the east, probably on the high Kherlen River. The Tuqi King of the Right lived in the west, perhaps near present-day Uliastai in the Khangai Mountains.

In the winter of 200 BC, following a siege of Taiyuan, Emperor Gaozu of Han personally led a military campaign against Modun. At the Battle of Baideng, he was ambushed reputedly by 300,000 elite Xiongnu cavalry. The emperor was cut off from supplies and reinforcements for seven days, only narrowly escaping capture.

The Han Chinese sent princesses to marry Xiongnu leaders in their efforts to stop the border raids. Along with arranged marriages, the Han sent gifts to bribe the Xiongnu to stop attacking. After the defeat at Pingcheng, the Han emperor abandoned a military solution to the Xiongnu threat. Instead, in 198BC, the courtier was dispatched for negotiations. The peace settlement eventually reached between the parties included a Han princess given in marriage to the "chanyu" (called "heqin" ); periodic gifts to the Xiongnu of silk, distilled beverages and rice; equal status between the states; and the Great Wall as mutual border.

This first treaty set the pattern for relations between the Han and the Xiongnu for sixty years. Up to 135 BC, the treaty was renewed nine times, each time with an increase in the "gifts". In 192 BC, Modun even asked for the hand of Emperor Gao's widow Empress Lü Zhi. His son and successor, the energetic Jiyu, known as the Laoshang Chanyu, continued his father's expansionist policies. Laoshang succeeded in negotiating with Emperor Wen terms for the maintenance of a large scale government sponsored market system.

While the Xiongnu benefited handsomely, from the Chinese perspective marriage treaties were costly, humiliating, and ineffective. Laoshang showed that he did not take the peace treaty seriously. On one occasion his scouts penetrated to a point near Chang'an. In 166 BC he personally led 140,000 cavalry to invade Anding, reaching as far as the imperial retreat at Yong. In 158 BC, his successor sent 30,000 cavalry to attack Shangdang and another 30,000 to Yunzhong.

The Xiongnu also practiced marriage alliances with Han dynasty officers and officials who defected to their side. The older sister of the Chanyu (the Xiongnu ruler) was married to the Xiongnu General Zhao Xin, the Marquis of Xi who was serving the Han dynasty. The daughter of the Chanyu was married to the Han Chinese General Li Ling after he surrendered and defected. The Yenisei Kirghiz Khagans claimed descent from Li Ling. Another Han Chinese General who defected to the Xiongnu was Li Guangli who also married a daughter of the Chanyu.

When the Eastern Jin dynasty ended the Xianbei Northern Wei received the Han Chinese Jin prince Sima Chuzhi 司馬楚之 as a refugee. A Northern Wei Xianbei Princess married Sima Chuzhi, giving birth to Sima Jinlong 司馬金龍. Northern Liang Xiongnu King Juqu Mujian's daughter married Sima Jinlong.

The Han dynasty made preparations for war when the Han Emperor Wu dispatched the explorer Zhang Qian to explore the mysterious kingdoms to the west and to form an alliance with the Yuezhi people in order to combat the Xiongnu. During this time Zhang married a Xiongnu wife, who bore him a son, and gained the trust of the Xiongnu leader. While Zhang Qian did not succeed in this mission, his reports of the west provided even greater incentive to counter the Xiongnu hold on westward routes out of China, and the Chinese prepared to mount a large scale attack using the Northern Silk Road to move men and material.

While Han China was making preparations for a military confrontation from the reign of Emperor Wen, the break did not come until 133 BC, following an abortive trap to ambush the "chanyu" at Mayi. By that point the empire was consolidated politically, militarily and economically, and was led by an adventurous pro-war faction at court. In that year, Emperor Wu reversed the decision he had made the year before to renew the peace treaty.

In 53 BC Huhanye (呼韓邪) decided to enter into tributary relations with Han China. The original terms insisted on by the Han court were that, first, the "chanyu" or his representatives should come to the capital to pay homage; secondly, the "chanyu" should send a hostage prince; and thirdly, the "chanyu" should present tribute to the Han emperor. The political status of the Xiongnu in the Chinese world order was reduced from that of a "brotherly state" to that of an "outer vassal" (外臣). During this period, however, the Xiongnu maintained political sovereignty and full territorial integrity. The Great Wall of China continued to serve as the line of demarcation between Han and Xiongnu.

Huhanye sent his son, the "wise king of the right" Shuloujutang, to the Han court as hostage. In 51 BC he personally visited Chang'an to pay homage to the emperor on the Lunar New Year. In the same year, another envoy Qijushan (稽居狦) was received at the Sweet Spring Palace in the north west of modern Shanxi. On the financial side, Huhanye was amply rewarded in large quantities of gold, cash, clothes, silk, horses and grain for his participation. Huhanye made two further homage trips, in 49 BC and 33 BC; with each one the imperial gifts were increased. On the last trip, Huhanye took the opportunity to ask to be allowed to become an imperial son-in-law. As a sign of the decline in the political status of the Xiongnu, Emperor Yuan refused, giving him instead five ladies-in-waiting. One of them was Wang Zhaojun, famed in Chinese folklore as one of the Four Beauties.

When Zhizhi learned of his brother's submission, he also sent a son to the Han court as hostage in 53 BC. Then twice, in 51 BC and 50 BC, he sent envoys to the Han court with tribute. But having failed to pay homage personally, he was never admitted to the tributary system. In 36 BC, a junior officer named Chen Tang, with the help of Gan Yanshou, protector-general of the Western Regions, assembled an expeditionary force that defeated him at the Battle of Zhizhi and sent his head as a trophy to Chang'an.

Tributary relations were discontinued during the reign of Huduershi (18 AD–48), corresponding to the political upheavals of the Xin Dynasty in China. The Xiongnu took the opportunity to regain control of the western regions, as well as neighbouring peoples such as the Wuhuan. In 24 AD, Hudershi even talked about reversing the tributary system.

The Xiongnu's new power was met with a policy of appeasement by Emperor Guangwu. At the height of his power, Huduershi even compared himself to his illustrious ancestor, Modu. Due to growing regionalism among the Xiongnu, however, Huduershi was never able to establish unquestioned authority. In contravention of a principle of fraternal succession established by Huhanye, Huduershi designated his son Punu as heir-apparent. However, as the eldest son of the preceding "chanyu", Bi (Pi) – the Rizhu King of the Right – had a more legitimate claim. Consequently, Bi refused to attend the annual meeting at the "chanyu"'s court. Nevertheless, in 46 AD, Punu ascended the throne.

In 48 AD, a confederation of eight Xiongnu tribes in Bi's power base in the south, with a military force totalling 40,000 to 50,000 men, seceded from Punu's kingdom and acclaimed Bi as "chanyu". This kingdom became known as the Southern Xiongnu.

The rump kingdom under Punu, around the Orkhon (modern north central Mongolia) became known as the Northern Xiongnu. Punu, who became known as the Northern "Chanyu", began to put military pressure on the Southern Xiongnu.

In 49 AD, Tsi Yung, a Han governor of Liaodong, allied with the Wuhuan and Xianbei, attacked the Northern Xiongnu.
The Northern Xiongnu suffered two major defeats: one at the hands of the Xianbei in 85 AD, and by the Han during the Battle of Ikh Bayan, in 89 AD. The northern "chanyu" fled to the north-west with his subjects.

In about 155 AD, the Northern Xiongnu were decisively "crushed and subjugated" by the Xianbei.

Coincidentally, the Southern Xiongnu were plagued by natural disasters and misfortunes – in addition to the threat posed by Punu. Consequently, in 50 AD, the Southern Xiongnu submitted to tributary relations with Han China. The system of tribute was considerably tightened by the Han, to keep the Southern Xiongnu under control. The "chanyu" was ordered to establish his court in the Meiji district of Xihe commandery and the Southern Xiongnu were resettled in eight frontier commanderies. At the same time, large numbers of Chinese were also resettled in these commanderies, in mixed Han-Xiongnu settlements.
Economically, the Southern Xiongnu became reliant on trade with the Han.

Tensions were evident between Han settlers and practitioners of the nomadic way of life. Thus, in 94, Anguo Chanyu joined forces with newly subjugated Xiongnu from the north and started a large scale rebellion against the Han.

During the late 2nd century AD, the southern Xiongnu were drawn into the rebellions then plaguing the Han court. In 188, the "chanyu" was murdered by some of his own subjects for agreeing to send troops to help the Han suppress a rebellion in Hebei – many of the Xiongnu feared that it would set a precedent for unending military service to the Han court. The murdered "chanyu's" son Yufuluo, entitled Chizhisizhu (), succeeded him, but was then overthrown by the same rebellious faction in 189. He travelled to Luoyang (the Han capital) to seek aid from the Han court, but at this time the Han court was in disorder from the clash between Grand General He Jin and the eunuchs, and the intervention of the warlord Dong Zhuo. The "chanyu" had no choice but to settle down with his followers in Pingyang, a city in Shanxi. In 195, he died and was succeeded as "chanyu" by his brother Huchuquan Chanyu.

In 215–216 AD, the warlord-statesman Cao Cao detained Huchuquan Chanyu in the city of Ye, and divided his followers in Shanxi into five divisions: left, right, south, north, and centre. This was aimed at preventing the exiled Xiongnu in Shanxi from engaging in rebellion, and also allowed Cao Cao to use the Xiongnu as auxiliaries in his cavalry.

Later the Xiongnu aristocracy in Shanxi changed their surname from Luanti to Liu for prestige reasons, claiming that they were related to the Han imperial clan through the old intermarriage policy.
After Huchuquan, the Southern Xiongnu were partitioned into five local tribes. Each local chief was under the "surveillance of a chinese resident", while the shanyu was in "semicaptivity at the imperial court."

In 304, Liu Yuan became Chanyu of the Five Hordes. In 308, declared himself emperor and founded the Han Zhao Dynasty. In 311, his son and successor Liu Cong captured Luoyang, and with it the Emperor Huai of Jin China.

In 316, the Emperor Min of Jin China was captured in Chang'an. Both emperors were humiliated as cupbearers in Linfen before being executed in 313 and 318.

North China came under Xiongnu rule while the remnants of the Jin dynasty survived in the south at Jiankang.

In 318, after suppressing a coup by a powerful minister in the Xiongnu-Han court, in which the emperor and a large proportion of the aristocracy were massacred), the Xiongnu prince Liu Yao moved the Xiongnu-Han capital from Pingyang to Chang'an and renamed the dynasty as Zhao (Liu Yuan had declared the empire's name Han to create a linkage with Han Dynasty—to which he claimed he was a descendant, through a princess, but Liu Yao felt that it was time to end the linkage with Han and explicitly restore the linkage to the great Xiongnu chanyu Maodun, and therefore decided to change the name of the state. (However, this was not a break from Liu Yuan, as he continued to honor Liu Yuan and Liu Cong posthumously; it is hence known to historians collectively as Han Zhao).

However, the eastern part of north China came under the control of a rebel Xiongnu-Han general of Jie ancestry named Shi Le. Liu Yao and Shi Le fought a long war until 329, when Liu Yao was captured in battle and executed. Chang'an fell to Shi Le soon after, and the Xiongnu dynasty was wiped out. North China was ruled by Shi Le's Later Zhao dynasty for the next 20 years.

However, the "Liu" Xiongnu remained active in the north for at least another century.

The northern Tiefu branch of the Xiongnu gained control of the Inner Mongolian region in the 10 years between the conquest of the Tuoba Xianbei state of Dai by the Former Qin empire in 376, and its restoration in 386 as the Northern Wei. After 386, the Tiefu were gradually destroyed by or surrendered to the Tuoba, with the submitting Tiefu becoming known as the Dugu. Liu Bobo, a surviving prince of the Tiefu fled to the Ordos Loop, where he founded a state called the Xia (thus named because of the Xiongnu's supposed ancestry from the Xia dynasty) and changed his surname to Helian (赫連). The Helian-Xia state was conquered by the Northern Wei in 428–31, and the Xiongnu thenceforth effectively ceased to play a major role in Chinese history, assimilating into the Xianbei and Han ethnicities.

Tongwancheng (meaning "Unite All Nations") was the capital of the Xia (Sixteen Kingdoms), whose rulers claimed descent from Modu Chanyu.

The ruined city was discovered in 1996 and the State Council designated it as a cultural relic under top state protection. The repair of the Yong'an Platform, where Helian Bobo, emperor of the Da Xia regime, reviewed parading troops, has been finished and restoration on the 31-meter-tall turret follows.

The Juqu were a branch of the Xiongnu. Their leader Juqu Mengxun took over the Northern Liang by overthrowing the former puppet ruler Duan Ye. By 439, the Juqu power was destroyed by the Northern Wei. Their remnants were then settled in the city of Gaochang before being destroyed by the Rouran.

The sound of the first Chinese character (匈) has been reconstructed as in Old Chinese. The Chinese name for the Xiongnu was a pejorative term in itself, as the characters have the meaning of "fierce slave". The Chinese characters are pronounced as "Xiōngnú" in modern Mandarin Chinese.

The supposed Old Chinese sound of the first character (匈) has a possible similarity with the name "Hun" in European languages. The second character (奴) appears to have no parallel in Western terminology. Whether the similarity is evidence of kinship or mere coincidence is hard to tell. It could lend credence to the theory that the Huns were in fact descendants of the Northern Xiongnu who migrated westward, or that the Huns were using a name borrowed from the Northern Xiongnu, or that these Xiongnu made up part of the Hun confederation.

The Xiongnu-Hun hypothesis originated with the 18th-century French historian Joseph de Guignes, who noticed that ancient Chinese scholars had referred to members of tribes associated with the Xiongnu by names similar to "Hun", albeit with varying Chinese characters. Étienne de la Vaissière has shown that, in the Sogdian script used in the so-called "Sogdian Ancient Letters", both the Xiongnu and Huns were referred to as γwn ("xwn"), indicating that the two were synonymous. Although the theory that the Xiongnu were precursors of the Huns known later in Europe is now accepted by many scholars, it has yet to become a consensus view. The identification with the Huns may be either incorrect or an oversimplification (as would appear to be the case with a proto-Mongol people, the Rouran, who have sometimes been linked to the Avars of Central Europe).

Harold Walter Bailey proposed an Iranian origin of the Xiongnu, recognizing all the earliest Xiongnu names of the 2nd century BC as being of the Iranian type. This theory is supported by turkologist. Central Asian scholar Christopher I. Beckwith notes that the Xiongnu name could be a cognate of Scythian, Saka and Sogdia, corresponding to a name for Northern Iranians. According to Beckwith the Xiongnu could have contained a leading Iranian component when they started out, but more likely they had earlier been subjects of an Iranian people and learned from them the Iranian nomadic model.

In the UNESCO-published "History of Civilizations of Central Asia", its editor János Harmatta concludes that the royal tribes and kings of the Xiongnu bore Iranian names, that all Xiongnu words noted by the Chinese can be explained from a Scythian language, and that it is therefore clear that the majority of Hsiung-nu tribes spoke an Eastern Iranian language.

Mongolian and other scholars have suggested that the Xiongnu spoke a language related to the Mongolic languages. Mongolian archaeologists proposed that the Slab Grave Culture people were the ancestors of the Xiongnu, and some scholars have suggested that the Xiongnu may have been the ancestors of the Mongols. According to the "Book of Song", (section Joujan), Joujan's (Rouran Khaganate) alternative name was "Tatar" or "Tartar" and they were a Xiongnu tribe". Nikita Bichurin considered Xiongnu and Xianbei to be two subgroups (or dynasties) but the same ethnicity.

Genghis Khan refers to the time of Modu Chanyu as "the remote times of our Chanyu" in his letter to Daoist Qiu Chuji. Sun and moon symbol of Xiongnu that discovered by archaeologists is similar to Mongolian Soyombo symbol.

Proponents of a Turkic language theory include E.H. Parker, Jean-Pierre Abel-Rémusat, Julius Klaproth, Kurakichi Shiratori, Gustaf John Ramstedt, Annemarie von Gabain, and Omeljan Pritsak. Some sources say the ruling class was proto-Turkic, while others suggest it was proto-Hun. Craig Benjamin sees the Xiongnu as either proto-Turks or proto-Mongols who possibly spoke a language related to the Dingling.

Both the 7th-century Chinese "History of the Northern Dynasties" and the "Book of Zhou", an inscription in the Sogdian language, report the Turks to be a subgroup of the Huns.

Since the early 19th century, a number of Western scholars have proposed a connection between various language families or subfamilies and the language or languages of the Xiongnu. Albert Terrien de Lacouperie considered them to be multi-component groups. Many scholars believe the Xiongnu confederation was a mixture of different ethno-linguistic groups, and that their main language (as represented in the Chinese sources) and its relationships have not yet been satisfactorily determined. Kim rejects "old racial theories or even ethnic affiliations" in favour of the "historical reality of these extensive, multiethnic, polyglot steppe empires".

The Turkologist Gerhard Doerfer has denied any possibility of a relationship between the Xiongnu language and any other known language and rejected in the strongest terms any connection with Turkic or Mongolian.

The original geographic location of the Xiongnu is disputed among steppe archaeologists. Since the 1960s, the geographic origin of the Xiongnu has attempted to be traced through an analysis of Early Iron Age burial constructions. No region has been proven to have mortuary practices that clearly match that of the Xiongnu.

The political center of the Xiongnu state was in Mongolia and almost all of the Xiongnu kings were buried in Mongolia.

Classifications of these burial sites make distinction between two prevailing type of burials: "(1). monumental ramped terrace tombs which are often flanked by smaller "satellite" burials and (2) 'circular' or 'ring' burials." Some scholars consider this a division between "elite" graves and "commoner" graves. Other scholars, find this division too simplistic and not evocative of a true distinction because it shows "ignorance of the nature of the mortuary investments and typically luxuriant burial assemblages [and does not account for] the discovery of other lesser interments that do not qualify as either of these types."

A majority (89%) of Xiongnu mitochondrial sequences from the Egyin Gol Valley can be classified as belonging to Asian haplogroups, and nearly 11% belong to European mitochondrial haplogroups.

Over the past decade, Chinese archaeologists have published several reviews regarding the results of excavations in Xinjiang. They imply the Xiongnu's supreme ruling class. Particularly interesting are the tombs in the cemetery at Heigouliang, Xinjiang (the Black Gouliang cemetery, also known as the summer palace of the Xiongnu king), east of the Barkol basin, near the city of Hami. By typing results of DNA samples during the excavation of one of the tombs, it was determined that of the 12 men: 6 Q1a* (not Q1a1-M120, not Q1a1b-M25, not Q1a2-M3), 4 Q1b-M378, 2 Q* (not Q1a, not Q1b: unable to determine subclades):

The rock art of the Yin and Helan Mountains is dated from the 9th millennium BC to the 19th century AD. It consists mainly of engraved signs (petroglyphs) and only minimally of painted images.

Excavations conducted between 1924 and 1925 in the Noin-Ula kurgans produced objects with over twenty carved characters, which were either identical or very similar to that of to the runic letters of the Old Turkic alphabet discovered in the Orkhon Valley. From this a some scholars hold that the Xiongnu had a script similar to Eurasian runiform and this alphabet itself served as the basis for the ancient Turkic writing.

The "Records of the Grand Historian" (vol. ) state that when the Xiongnu noted down something or transmitted a message, they made cuts on a piece of wood; they also mention a "Hu script".
Xiongnu were a nomadic people. From their lifestyle of herding flocks and their horse-trade with China, we can conclude that their diet consist mainly of mutton, horse meat and wild geese that were shot down.

In various kinds of ancient inscriptions on monuments of Munmu of Silla, it is recorded that King Silla came from Xiongnu. Also, there are some Korean researchers point out grave goods of Silla and Xiongnu are alike and also some researchers propose that Silla King is descended from Xiongnu. The Korean traditional cloth Hanbok shows some Iranian influence. The royal Crowns of Silla are identical to Persian Crowns found in today Afghanistan. About this, the Korean public broadcaster KBS has reported a documentary.

Xiongnu

The Xiongnu () were a confederation of nomadic peoples who, according to ancient Chinese sources, inhabited the eastern Asian Steppe from the 3rd century BC to the late 1st century AD. Chinese sources report that Modu Chanyu, the supreme leader after 209 BC, founded the Xiongnu Empire.

After their previous overlords, the Yuezhi, migrated into Central Asia during the 2nd century BC, the Xiongnu became a dominant power on the steppes of north-east Central Asia, centred on an area known later as Mongolia. The Xiongnu were also active in areas now part of Siberia, Inner Mongolia, Gansu and Xinjiang. Their relations with adjacent Chinese dynasties to the south east were complex, with repeated periods of conflict and intrigue, alternating with exchanges of tribute, trade, and marriage treaties.

Attempts to identify the Xiongnu with later groups of the western Eurasian Steppe remain controversial. Scythians and Sarmatians were concurrently to the west. The identity of the ethnic core of Xiongnu has been a subject of varied hypotheses, because only a few words, mainly titles and personal names, were preserved in the Chinese sources. The name "Xiongnu" may be cognate with that of the Huns or the "Huna", although this is disputed. Other linguistic links – all of them also controversial – proposed by scholars include Iranian, Mongolic, Turkic, Uralic, Yeniseian, Tibeto-Burman or multi-ethnic.

An early reference to the Xiongnu was by the Han dynasty historian Sima Qian who wrote about the Xiongnu in the "Records of the Grand Historian" ( BC), drawing a distinct line between the settled Huaxia people (Chinese) to the pastoral nomads (Xiongnu), characterizing it as two polar groups in the sense of a civilization versus an uncivilized society: the Hua–Yi distinction. Pre-Han sources often classify the Xiongnu as a "Hu" people, which was a blanket term for nomadic people in general; it only became an ethnonym for the Xiongnu during the Han.

Ancient China often came in contact with the Xianyun and the Xirong nomadic peoples. In later Chinese historiography, some groups of these peoples were believed to be the possible progenitors of the Xiongnu people. These nomadic people often had repeated military confrontations with the Shang and especially the Zhou, who often conquered and enslaved the nomads in an expansion drift. During the Warring States period, the armies from the Qin, Zhao, and Yan states were encroaching and conquering various nomadic territories that were inhabited by the Xiongnu and other Hu peoples.

After forging internal unity, Modu expanded the empire on all sides. To the north he conquered a number of nomadic peoples, including the Dingling of southern Siberia. He crushed the power of the Donghu people of eastern Mongolia and Manchuria as well as the Yuezhi in the Hexi Corridor of Gansu, where his son, Jizhu, made a skull cup out of the Yuezhi king. Modu also reoccupied all the lands previously taken by the Qin general Meng Tian.

Under Modu's leadership, the Xiongnu threatened the Han dynasty, almost causing Emperor Gaozu, the first Han emperor, to lose his throne in 200 BC. By the time of Modu's death in 174 BC, the Xiongnu had driven the Yuezhi from the Hexi Corridor, killing the Yuezhi king in the process and asserting their presence in the Western Regions.

The Xiongnu were recognized as the most prominent of the nomads bordering the Chinese Han empire and during early relations between the Xiongnu and the Han, the former held the balance of power. According to the "Book of Han", later quoted in Duan Chengshi's ninth century "Miscellaneous Morsels from Youyang":

After Modu, later leaders formed a dualistic system of political organisation with the left and right branches of the Xiongnu divided on a regional basis. The "chanyu" or "shanyu", a ruler equivalent to the Emperor of China, exercised direct authority over the central territory. Longcheng (蘢城), near the Orkhon inscriptions in modern Mongolia, became the annual meeting place and served as the Xiongnu capital.

The ruler of the Xiongnu was called the Chanyu. Under him were the Tuqi Kings. The Tuqi King of the Left was normally the heir presumptive. Next lower in the hierarchy came more officials in pairs of left and right: the "guli", the army commanders, the great governors, the "dunghu" and the "gudu". Beneath them came the commanders of detachments of one thousand, of one hundred, and of ten men. This nation of nomads, a people on the march, was organized like an army.

Yap, apparently describing the early period, places the Chanyu's main camp north of Shanxi with the Tuqi King of the Left holding the area north of Beijing and the Tuqi King of the Right holding the Ordos Loop area as far as Gansu. Grousset, probably describing the situation after the Xiongnu had been driven north, places the Chanyu on the upper Orkhon River near where Genghis Khan would later establish his capital of Karakorum. The Tuqi King of the Left lived in the east, probably on the high Kherlen River. The Tuqi King of the Right lived in the west, perhaps near present-day Uliastai in the Khangai Mountains.

In the winter of 200 BC, following a siege of Taiyuan, Emperor Gaozu of Han personally led a military campaign against Modun. At the Battle of Baideng, he was ambushed reputedly by 300,000 elite Xiongnu cavalry. The emperor was cut off from supplies and reinforcements for seven days, only narrowly escaping capture.

The Han Chinese sent princesses to marry Xiongnu leaders in their efforts to stop the border raids. Along with arranged marriages, the Han sent gifts to bribe the Xiongnu to stop attacking. After the defeat at Pingcheng, the Han emperor abandoned a military solution to the Xiongnu threat. Instead, in 198BC, the courtier was dispatched for negotiations. The peace settlement eventually reached between the parties included a Han princess given in marriage to the "chanyu" (called "heqin" ); periodic gifts to the Xiongnu of silk, distilled beverages and rice; equal status between the states; and the Great Wall as mutual border.

This first treaty set the pattern for relations between the Han and the Xiongnu for sixty years. Up to 135 BC, the treaty was renewed nine times, each time with an increase in the "gifts". In 192 BC, Modun even asked for the hand of Emperor Gao's widow Empress Lü Zhi. His son and successor, the energetic Jiyu, known as the Laoshang Chanyu, continued his father's expansionist policies. Laoshang succeeded in negotiating with Emperor Wen terms for the maintenance of a large scale government sponsored market system.

While the Xiongnu benefited handsomely, from the Chinese perspective marriage treaties were costly, humiliating, and ineffective. Laoshang showed that he did not take the peace treaty seriously. On one occasion his scouts penetrated to a point near Chang'an. In 166 BC he personally led 140,000 cavalry to invade Anding, reaching as far as the imperial retreat at Yong. In 158 BC, his successor sent 30,000 cavalry to attack Shangdang and another 30,000 to Yunzhong.

The Xiongnu also practiced marriage alliances with Han dynasty officers and officials who defected to their side. The older sister of the Chanyu (the Xiongnu ruler) was married to the Xiongnu General Zhao Xin, the Marquis of Xi who was serving the Han dynasty. The daughter of the Chanyu was married to the Han Chinese General Li Ling after he surrendered and defected. The Yenisei Kirghiz Khagans claimed descent from Li Ling. Another Han Chinese General who defected to the Xiongnu was Li Guangli who also married a daughter of the Chanyu.

When the Eastern Jin dynasty ended the Xianbei Northern Wei received the Han Chinese Jin prince Sima Chuzhi 司馬楚之 as a refugee. A Northern Wei Xianbei Princess married Sima Chuzhi, giving birth to Sima Jinlong 司馬金龍. Northern Liang Xiongnu King Juqu Mujian's daughter married Sima Jinlong.

The Han dynasty made preparations for war when the Han Emperor Wu dispatched the explorer Zhang Qian to explore the mysterious kingdoms to the west and to form an alliance with the Yuezhi people in order to combat the Xiongnu. During this time Zhang married a Xiongnu wife, who bore him a son, and gained the trust of the Xiongnu leader. While Zhang Qian did not succeed in this mission, his reports of the west provided even greater incentive to counter the Xiongnu hold on westward routes out of China, and the Chinese prepared to mount a large scale attack using the Northern Silk Road to move men and material.

While Han China was making preparations for a military confrontation from the reign of Emperor Wen, the break did not come until 133 BC, following an abortive trap to ambush the "chanyu" at Mayi. By that point the empire was consolidated politically, militarily and economically, and was led by an adventurous pro-war faction at court. In that year, Emperor Wu reversed the decision he had made the year before to renew the peace treaty.

In 53 BC Huhanye (呼韓邪) decided to enter into tributary relations with Han China. The original terms insisted on by the Han court were that, first, the "chanyu" or his representatives should come to the capital to pay homage; secondly, the "chanyu" should send a hostage prince; and thirdly, the "chanyu" should present tribute to the Han emperor. The political status of the Xiongnu in the Chinese world order was reduced from that of a "brotherly state" to that of an "outer vassal" (外臣). During this period, however, the Xiongnu maintained political sovereignty and full territorial integrity. The Great Wall of China continued to serve as the line of demarcation between Han and Xiongnu.

Huhanye sent his son, the "wise king of the right" Shuloujutang, to the Han court as hostage. In 51 BC he personally visited Chang'an to pay homage to the emperor on the Lunar New Year. In the same year, another envoy Qijushan (稽居狦) was received at the Sweet Spring Palace in the north west of modern Shanxi. On the financial side, Huhanye was amply rewarded in large quantities of gold, cash, clothes, silk, horses and grain for his participation. Huhanye made two further homage trips, in 49 BC and 33 BC; with each one the imperial gifts were increased. On the last trip, Huhanye took the opportunity to ask to be allowed to become an imperial son-in-law. As a sign of the decline in the political status of the Xiongnu, Emperor Yuan refused, giving him instead five ladies-in-waiting. One of them was Wang Zhaojun, famed in Chinese folklore as one of the Four Beauties.

When Zhizhi learned of his brother's submission, he also sent a son to the Han court as hostage in 53 BC. Then twice, in 51 BC and 50 BC, he sent envoys to the Han court with tribute. But having failed to pay homage personally, he was never admitted to the tributary system. In 36 BC, a junior officer named Chen Tang, with the help of Gan Yanshou, protector-general of the Western Regions, assembled an expeditionary force that defeated him at the Battle of Zhizhi and sent his head as a trophy to Chang'an.

Tributary relations were discontinued during the reign of Huduershi (18 AD–48), corresponding to the political upheavals of the Xin Dynasty in China. The Xiongnu took the opportunity to regain control of the western regions, as well as neighbouring peoples such as the Wuhuan. In 24 AD, Hudershi even talked about reversing the tributary system.

The Xiongnu's new power was met with a policy of appeasement by Emperor Guangwu. At the height of his power, Huduershi even compared himself to his illustrious ancestor, Modu. Due to growing regionalism among the Xiongnu, however, Huduershi was never able to establish unquestioned authority. In contravention of a principle of fraternal succession established by Huhanye, Huduershi designated his son Punu as heir-apparent. However, as the eldest son of the preceding "chanyu", Bi (Pi) – the Rizhu King of the Right – had a more legitimate claim. Consequently, Bi refused to attend the annual meeting at the "chanyu"'s court. Nevertheless, in 46 AD, Punu ascended the throne.

In 48 AD, a confederation of eight Xiongnu tribes in Bi's power base in the south, with a military force totalling 40,000 to 50,000 men, seceded from Punu's kingdom and acclaimed Bi as "chanyu". This kingdom became known as the Southern Xiongnu.

The rump kingdom under Punu, around the Orkhon (modern north central Mongolia) became known as the Northern Xiongnu. Punu, who became known as the Northern "Chanyu", began to put military pressure on the Southern Xiongnu.

In 49 AD, Tsi Yung, a Han governor of Liaodong, allied with the Wuhuan and Xianbei, attacked the Northern Xiongnu.
The Northern Xiongnu suffered two major defeats: one at the hands of the Xianbei in 85 AD, and by the Han during the Battle of Ikh Bayan, in 89 AD. The northern "chanyu" fled to the north-west with his subjects.

In about 155 AD, the Northern Xiongnu were decisively "crushed and subjugated" by the Xianbei.

Coincidentally, the Southern Xiongnu were plagued by natural disasters and misfortunes – in addition to the threat posed by Punu. Consequently, in 50 AD, the Southern Xiongnu submitted to tributary relations with Han China. The system of tribute was considerably tightened by the Han, to keep the Southern Xiongnu under control. The "chanyu" was ordered to establish his court in the Meiji district of Xihe commandery and the Southern Xiongnu were resettled in eight frontier commanderies. At the same time, large numbers of Chinese were also resettled in these commanderies, in mixed Han-Xiongnu settlements.
Economically, the Southern Xiongnu became reliant on trade with the Han.

Tensions were evident between Han settlers and practitioners of the nomadic way of life. Thus, in 94, Anguo Chanyu joined forces with newly subjugated Xiongnu from the north and started a large scale rebellion against the Han.

During the late 2nd century AD, the southern Xiongnu were drawn into the rebellions then plaguing the Han court. In 188, the "chanyu" was murdered by some of his own subjects for agreeing to send troops to help the Han suppress a rebellion in Hebei – many of the Xiongnu feared that it would set a precedent for unending military service to the Han court. The murdered "chanyu's" son Yufuluo, entitled Chizhisizhu (), succeeded him, but was then overthrown by the same rebellious faction in 189. He travelled to Luoyang (the Han capital) to seek aid from the Han court, but at this time the Han court was in disorder from the clash between Grand General He Jin and the eunuchs, and the intervention of the warlord Dong Zhuo. The "chanyu" had no choice but to settle down with his followers in Pingyang, a city in Shanxi. In 195, he died and was succeeded as "chanyu" by his brother Huchuquan Chanyu.

In 215–216 AD, the warlord-statesman Cao Cao detained Huchuquan Chanyu in the city of Ye, and divided his followers in Shanxi into five divisions: left, right, south, north, and centre. This was aimed at preventing the exiled Xiongnu in Shanxi from engaging in rebellion, and also allowed Cao Cao to use the Xiongnu as auxiliaries in his cavalry.

Later the Xiongnu aristocracy in Shanxi changed their surname from Luanti to Liu for prestige reasons, claiming that they were related to the Han imperial clan through the old intermarriage policy.
After Huchuquan, the Southern Xiongnu were partitioned into five local tribes. Each local chief was under the "surveillance of a chinese resident", while the shanyu was in "semicaptivity at the imperial court."

In 304, Liu Yuan became Chanyu of the Five Hordes. In 308, declared himself emperor and founded the Han Zhao Dynasty. In 311, his son and successor Liu Cong captured Luoyang, and with it the Emperor Huai of Jin China.

In 316, the Emperor Min of Jin China was captured in Chang'an. Both emperors were humiliated as cupbearers in Linfen before being executed in 313 and 318.

North China came under Xiongnu rule while the remnants of the Jin dynasty survived in the south at Jiankang.

In 318, after suppressing a coup by a powerful minister in the Xiongnu-Han court, in which the emperor and a large proportion of the aristocracy were massacred), the Xiongnu prince Liu Yao moved the Xiongnu-Han capital from Pingyang to Chang'an and renamed the dynasty as Zhao (Liu Yuan had declared the empire's name Han to create a linkage with Han Dynasty—to which he claimed he was a descendant, through a princess, but Liu Yao felt that it was time to end the linkage with Han and explicitly restore the linkage to the great Xiongnu chanyu Maodun, and therefore decided to change the name of the state. (However, this was not a break from Liu Yuan, as he continued to honor Liu Yuan and Liu Cong posthumously; it is hence known to historians collectively as Han Zhao).

However, the eastern part of north China came under the control of a rebel Xiongnu-Han general of Jie ancestry named Shi Le. Liu Yao and Shi Le fought a long war until 329, when Liu Yao was captured in battle and executed. Chang'an fell to Shi Le soon after, and the Xiongnu dynasty was wiped out. North China was ruled by Shi Le's Later Zhao dynasty for the next 20 years.

However, the "Liu" Xiongnu remained active in the north for at least another century.

The northern Tiefu branch of the Xiongnu gained control of the Inner Mongolian region in the 10 years between the conquest of the Tuoba Xianbei state of Dai by the Former Qin empire in 376, and its restoration in 386 as the Northern Wei. After 386, the Tiefu were gradually destroyed by or surrendered to the Tuoba, with the submitting Tiefu becoming known as the Dugu. Liu Bobo, a surviving prince of the Tiefu fled to the Ordos Loop, where he founded a state called the Xia (thus named because of the Xiongnu's supposed ancestry from the Xia dynasty) and changed his surname to Helian (赫連). The Helian-Xia state was conquered by the Northern Wei in 428–31, and the Xiongnu thenceforth effectively ceased to play a major role in Chinese history, assimilating into the Xianbei and Han ethnicities.

Tongwancheng (meaning "Unite All Nations") was the capital of the Xia (Sixteen Kingdoms), whose rulers claimed descent from Modu Chanyu.

The ruined city was discovered in 1996 and the State Council designated it as a cultural relic under top state protection. The repair of the Yong'an Platform, where Helian Bobo, emperor of the Da Xia regime, reviewed parading troops, has been finished and restoration on the 31-meter-tall turret follows.

The Juqu were a branch of the Xiongnu. Their leader Juqu Mengxun took over the Northern Liang by overthrowing the former puppet ruler Duan Ye. By 439, the Juqu power was destroyed by the Northern Wei. Their remnants were then settled in the city of Gaochang before being destroyed by the Rouran.

The sound of the first Chinese character (匈) has been reconstructed as in Old Chinese. The Chinese name for the Xiongnu was a pejorative term in itself, as the characters have the meaning of "fierce slave". The Chinese characters are pronounced as "Xiōngnú" in modern Mandarin Chinese.

The supposed Old Chinese sound of the first character (匈) has a possible similarity with the name "Hun" in European languages. The second character (奴) appears to have no parallel in Western terminology. Whether the similarity is evidence of kinship or mere coincidence is hard to tell. It could lend credence to the theory that the Huns were in fact descendants of the Northern Xiongnu who migrated westward, or that the Huns were using a name borrowed from the Northern Xiongnu, or that these Xiongnu made up part of the Hun confederation.

The Xiongnu-Hun hypothesis originated with the 18th-century French historian Joseph de Guignes, who noticed that ancient Chinese scholars had referred to members of tribes associated with the Xiongnu by names similar to "Hun", albeit with varying Chinese characters. Étienne de la Vaissière has shown that, in the Sogdian script used in the so-called "Sogdian Ancient Letters", both the Xiongnu and Huns were referred to as γwn ("xwn"), indicating that the two were synonymous. Although the theory that the Xiongnu were precursors of the Huns known later in Europe is now accepted by many scholars, it has yet to become a consensus view. The identification with the Huns may be either incorrect or an oversimplification (as would appear to be the case with a proto-Mongol people, the Rouran, who have sometimes been linked to the Avars of Central Europe).

Harold Walter Bailey proposed an Iranian origin of the Xiongnu, recognizing all the earliest Xiongnu names of the 2nd century BC as being of the Iranian type. This theory is supported by turkologist. Central Asian scholar Christopher I. Beckwith notes that the Xiongnu name could be a cognate of Scythian, Saka and Sogdia, corresponding to a name for Northern Iranians. According to Beckwith the Xiongnu could have contained a leading Iranian component when they started out, but more likely they had earlier been subjects of an Iranian people and learned from them the Iranian nomadic model.

In the UNESCO-published "History of Civilizations of Central Asia", its editor János Harmatta concludes that the royal tribes and kings of the Xiongnu bore Iranian names, that all Xiongnu words noted by the Chinese can be explained from a Scythian language, and that it is therefore clear that the majority of Hsiung-nu tribes spoke an Eastern Iranian language.

Mongolian and other scholars have suggested that the Xiongnu spoke a language related to the Mongolic languages. Mongolian archaeologists proposed that the Slab Grave Culture people were the ancestors of the Xiongnu, and some scholars have suggested that the Xiongnu may have been the ancestors of the Mongols. According to the "Book of Song", (section Joujan), Joujan's (Rouran Khaganate) alternative name was "Tatar" or "Tartar" and they were a Xiongnu tribe". Nikita Bichurin considered Xiongnu and Xianbei to be two subgroups (or dynasties) but the same ethnicity.

Genghis Khan refers to the time of Modu Chanyu as "the remote times of our Chanyu" in his letter to Daoist Qiu Chuji. Sun and moon symbol of Xiongnu that discovered by archaeologists is similar to Mongolian Soyombo symbol.

Proponents of a Turkic language theory include E.H. Parker, Jean-Pierre Abel-Rémusat, Julius Klaproth, Kurakichi Shiratori, Gustaf John Ramstedt, Annemarie von Gabain, and Omeljan Pritsak. Some sources say the ruling class was proto-Turkic, while others suggest it was proto-Hun. Craig Benjamin sees the Xiongnu as either proto-Turks or proto-Mongols who possibly spoke a language related to the Dingling.

Both the 7th-century Chinese "History of the Northern Dynasties" and the "Book of Zhou", an inscription in the Sogdian language, report the Turks to be a subgroup of the Huns.

Since the early 19th century, a number of Western scholars have proposed a connection between various language families or subfamilies and the language or languages of the Xiongnu. Albert Terrien de Lacouperie considered them to be multi-component groups. Many scholars believe the Xiongnu confederation was a mixture of different ethno-linguistic groups, and that their main language (as represented in the Chinese sources) and its relationships have not yet been satisfactorily determined. Kim rejects "old racial theories or even ethnic affiliations" in favour of the "historical reality of these extensive, multiethnic, polyglot steppe empires".

The Turkologist Gerhard Doerfer has denied any possibility of a relationship between the Xiongnu language and any other known language and rejected in the strongest terms any connection with Turkic or Mongolian.

The original geographic location of the Xiongnu is disputed among steppe archaeologists. Since the 1960s, the geographic origin of the Xiongnu has attempted to be traced through an analysis of Early Iron Age burial constructions. No region has been proven to have mortuary practices that clearly match that of the Xiongnu.

The political center of the Xiongnu state was in Mongolia and almost all of the Xiongnu kings were buried in Mongolia.

Classifications of these burial sites make distinction between two prevailing type of burials: "(1). monumental ramped terrace tombs which are often flanked by smaller "satellite" burials and (2) 'circular' or 'ring' burials." Some scholars consider this a division between "elite" graves and "commoner" graves. Other scholars, find this division too simplistic and not evocative of a true distinction because it shows "ignorance of the nature of the mortuary investments and typically luxuriant burial assemblages [and does not account for] the discovery of other lesser interments that do not qualify as either of these types."

A majority (89%) of Xiongnu mitochondrial sequences from the Egyin Gol Valley can be classified as belonging to Asian haplogroups, and nearly 11% belong to European mitochondrial haplogroups.

Over the past decade, Chinese archaeologists have published several reviews regarding the results of excavations in Xinjiang. They imply the Xiongnu's supreme ruling class. Particularly interesting are the tombs in the cemetery at Heigouliang, Xinjiang (the Black Gouliang cemetery, also known as the summer palace of the Xiongnu king), east of the Barkol basin, near the city of Hami. By typing results of DNA samples during the excavation of one of the tombs, it was determined that of the 12 men: 6 Q1a* (not Q1a1-M120, not Q1a1b-M25, not Q1a2-M3), 4 Q1b-M378, 2 Q* (not Q1a, not Q1b: unable to determine subclades):

Xiongnu art is harder to distinguish from Saka or Scythian art. There was a similarity present in stylistic execution, but Xiongnu art and Saka art did often differ in terms of iconography. Saka art does not appear to have included predation scenes, especially with dead prey, or same-animal combat. Additionally, Saka art included elements not common to Xiongnu iconography, such as a winged, horned horse. The two cultures also used two different bird heads. Xiongnu depictions of birds have a tendency to have a moderate eye and beak and have ears, while Saka birds have a pronounced eye and beak and no ears. Some scholars claim these differences are indicative of cultural differences. Scholar Sophia-Karin Psarras claims that Xiongnu images of animal predation, specifically tiger plus prey, is spiritual, representative of death and rebirth, and same-animal combat is representative of the acquisition of or maintenance of power.

The rock art of the Yin and Helan Mountains is dated from the 9th millennium BC to the 19th century AD. It consists mainly of engraved signs (petroglyphs) and only minimally of painted images.

Excavations conducted between 1924 and 1925 in the Noin-Ula kurgans produced objects with over twenty carved characters, which were either identical or very similar to that of to the runic letters of the Old Turkic alphabet discovered in the Orkhon Valley. From this a some scholars hold that the Xiongnu had a script similar to Eurasian runiform and this alphabet itself served as the basis for the ancient Turkic writing.

The "Records of the Grand Historian" (vol. ) state that when the Xiongnu noted down something or transmitted a message, they made cuts on a piece of wood; they also mention a "Hu script".
Xiongnu were a nomadic people. From their lifestyle of herding flocks and their horse-trade with China, we can conclude that their diet consist mainly of mutton, horse meat and wild geese that were shot down.

In various kinds of ancient inscriptions on monuments of Munmu of Silla, it is recorded that King Silla came from Xiongnu. Also, there are some Korean researchers point out grave goods of Silla and Xiongnu are alike and also some researchers propose that Silla King is descended from Xiongnu. The Korean traditional cloth Hanbok shows some Iranian influence. The royal Crowns of Silla are identical to Persian Crowns found in today Afghanistan. About this, the Korean public broadcaster KBS has reported a documentary.

The Xiongnu confederation ruled present-day Mongolia from the third century BCE through the first century CE, living in portable, round tents on carts and round yurts. The Xiongnu aristocracy lived in small palaces, and their villages were protected by huge walls. S. I. Rudenko also mentions capital construction built of logs. Archaeological excavations indicate that the Xiongnu had towns; their chief city was Luut Hot (Dragon City).

Architecture of Mongolia

The architecture of Mongolia is largely based on traditional dwellings, such as the yurt (, "ger") and the tent. During the 16th and 17th centuries, lamaseries were built throughout the country as temples which were later enlarged to accommodate a growing number of worshipers. Mongolian architects designed their temples with six and twelve angles and pyramidal roofs approximating the yurt's round shape. Further expansion led to a quadratic shape in the design of the temples, with roofs in the shape of pole marquees. Trellis walls, roof poles and layers of felt were eventually replaced by stone, brick beams and planks.

Mongolian artist and art historian N. Chultem identified three styles of traditional Mongolian architecture (Mongolian, Tibetan and Chinese), alone or in combination. Batu-Tsagaan (1654), designed by Zanabazar, was an early quadratic temple. The Dashchoilin Khiid monastery in Ulaanbaatar is an example of yurt-style architecture. The 18th century Lavrin Temple in the Erdene Zuu lamasery was built in the Tibetan tradition. The Choijin Lama Süm temple (1904), now a museum, is an example of a temple built in the Chinese tradition. The quadratic Tsogchin Temple, in Ulaanbaatar's Gandan monastery, combines Mongolian and Chinese traditions. The Maitreya Temple (demolished in 1938) was an example of Tibeto-Mongolian architecture. The Dashchoilin Khiid monastery has begun a project to restore this temple and the sculpture of Maitreya. Indian influences can also be seen in Mongolian architecture, especially in the design of Buddhist stupas.

Powerful states developed by Turkic and Uigur tribes from the sixth through ninth centuries dominated the region. and there were several Turkic cities and towns in the Orkhon, Tuul and Selenga River valleys. The main city of the Turkic Khaganate was Balyklyk. The Uyghur Khaganate which succeeded the Turks centred on the city of Kara Balgasun, founded during the early eighth century. A portion of the -high fortress wall with a watchtower has been preserved. A large craft trading district existed in the city, whose architecture was influenced by Sogdian and Chinese traditions.

Archaeological excavations uncovered traces of cities from the 10th- to 12th-century Kidan period. The most significant excavated city was Hatun Hot, founded in 944. Another significant Kidan city was Bars-Hot in the Kherlen River valley, which covered an area of. The city was surrounded with mud walls which are now thick and high.

The yurt, traditional dwelling of Mongolian nomads, is a circular structure supported by a collapsible wooden frame and covered with wool felt. In Mongolian, a yurt is known as a "ger" (гэр).

During the 12th and 13th centuries, "ger-tereg" (yurts on carts) were built for rulers. Large iron bushings for cartwheel axles were found during excavations at Karakorum. Axle length was over, and the cart was pulled by 22 oxen. Such "ger-teregs" are mentioned in the "Secret History of the Mongols".

Medieval yurt camps were commonly arranged in a "huree" (circle), with the leader's yurt in the centre. "Hurees" were replaced by an "ail" (neighbourhood) arrangement in the 13th and 14th centuries during the Mongol Khanate and the end of internal strife. After the 15th-century disintegration of the khanate, the "huree" was the basic layout of monasteries (which were initially mobile). Another type of monastery layout, "khiid" (following the Tibetan arrangement) was used during the 16th and 17th centuries when Buddhism was re-introduced to the region. As "huree" monasteries and camps developed into towns and cities, their names retained the word "huree" (for example, Niislel Huree and Zasagtu Khaan-u Huree).

Roofs originally had steeper slopes, with a rim around the center opening to allow smoke from central, open fires to vent. During the 18th and 19th centuries, enclosed stoves with chimneys ("zuuh") were introduced; this permitted a simpler design, with a lower silhouette. Another relatively-recent development is an additional layer of canvas for rain protection.

The organization and furnishings of the interior space mirror family roles and spiritual concepts. Each cardinal direction is significant, and the door always faces south. Herders use the sun's position in the crown of the yurt as a sundial.

Yurts have been used in Central Asia for thousands of years. In Mongolia they have influenced other architectural forms, particularly temples. Between 30 and 40 percent of the population live in yurts, many in city suburbs.

Tents played a role in the development of Mongolian architecture, and these temporary shelters were frequently used under pastoral conditions. Tents were erected for Naadam, feasts and other gatherings.

"Jodgor" is a small tent, accommodating one or two people. "Maihan" is a larger tent for a group. "Tsatsar" is a fabric shade on vertical supports, replacing a wall. "Tsachir" is a large, rectangular tent with vertical fabric walls, and "Asar" is a generic name for "tsatsar" and "tsachir".

Giovanni da Pian del Carpine's book, "Ystoria Mongalorum" ("History of the Mongols"), reported that during the 1246 enthronement ceremony for Guyuk Khaan a tent with a capacity of 2,000 people was erected on the Tamir River. The marquee was supported by pillars decorated with gold leaves, and the internal side of the walls were covered with canopy. Later designs of many temples were based on "tsachir".

The remains of the Mongol Empire capital, Karakorum, were first rediscovered and studied by S. V. Kiselev. Karakorum, in the Orkhon River valley, was founded by Genghis Khan in 1220 as a military centre; in 15 years, it also became an administrative and cultural centre of the empire.

The Tumen Amugulang palace (palace of the Great Khan) was in the centre of the city. Based on the records of William of Rubruck, most scholars believe that a silver, tree-shaped fountain stood in front of the palace; however, according to others the fountain was inside the palace. According to Rubruck, four silver lions stood at the foot of the Silver Tree and fermented mare's milk ("airag", a favourite Mongol drink) flowed from their mouths. Four golden serpents twined around the tree.
Wine ran from the mouth of one serpent, "airag" from the second serpent, mead from the third and rice wine from the fourth. At the top of the tree, an angel blew a bugle. The tree's branches, leaves and fruits were made of silver. It was designed by a captive sculptor, William of Paris. The khan sat on a throne in the north end of the yard, in front of the palace. Excavations partially confirmed the description, and the buildings were heated by smoke pipes installed under the floors. The khan's palace was built on a platform.

Genghis Khan's son, Ögedei, ordered his brothers, sons and other princes to build palaces in Karakorum. The city contained Buddhist temples, Christian churches and Muslim mosques. There were sculptures of tortoises at each gate of the four-sided, walled city. Steles on the tortoises' backs were topped with beacons for travellers in the steppe. Karakorun's construction was supervised by Otchigin, youngest brother of Genghis Khan.
Other cities and palaces existed throughout Mongolia during the 13th and 14th centuries. Best-studied are the ruins of Palace Aurug, near Kerulen, and the cities of Hirhira and Kondui in the trans-Baikal region. The latter two indicate that cities developed not only around the khans' palaces but also around the homes of other nobility; Hirhira developed around the residence of Juchi-Khasar. The Mongolian nobility, dissatisfied with temporary residences, began to build luxurious palaces. The palace in Hirhira was inside a citadel. The palace in Kondui was built on a platform surrounded by double-tiered terraces, pavilions and pools. The archeological excavations revealed evidence of burning; all three cities fell during the late 14th century, when the Chinese army raided the region and looted the cities. Karakorum, destroyed in 1380, never restored its previous glory. Wars waged by China continued from 1372 to 1422, halting Mongolia's cultural progress during the imperial period. The region experienced a dark age until the second half of the 16th century, when a renaissance began.

After two centuries of cultural decline, Mongolia began a renaissance during the second half of the 16th century. This was a period of relative peace, free of foreign aggression, and the Gelug school of Buddhism was introduced. Altan Khan of Tumet founded the city of Hohhot in 1575 as a political and cultural centre. Among the first Buddhist monasteries in Mongolia during this period was temple Thegchen Chonchor Ling in Khökh Nuur, built by Altan Khan to commemorate his 1577 meeting with third Dalai Lama Sonam Gyatso. Many temples were built in Hohhot during the period including Dazhao and Xilituzhao Temples.
In Khalkha, Abatai Khan founded the Erdene Zuu monastery in 1585 near the site of Karakorum. Although these first temples were designed in the Chinese style, Mongolian architecture developed a unique style with Tibetan and Indian influences.

The Mongolian style began with mobile temples. As the people became more sedentary, the temples evolved into multi-angular and quadratic structures. The roof, supported by pillars and walls, served also as the ceiling.
Zanabazar, the first Bogd Gegeen of the Khalkha Mongols, designed many temples and monasteries in traditional Mongolian style and supervised their construction. He merged Oriental architecture with the designs of Mongolian yurts and marquees. Zanabazar's Batu-Tsagaan Tsogchin temple in Ulan Bator was a prototype of the Mongolian architectural style. A large, marquee-shaped structure, its four central columns support the roof. There are 12 columns in the middle row; those in the outer row are slightly taller, and the total number of columns is 108. The temple, designed for expansion, was originally and later expanded to.

The Indian style was most prominent in stupa design. Among the best-known stupas are Ikh Tamir, Altan Suburgan of Erdene Zuu, Jiran Khashir of Gandang and the mausoleums of Abatai Khan and Tüsheetu Khan Gombodorji. The Khögnö Tarni (1600), Zaya-iin Khüree (1616), Baruun Khüree (1647) and Zaya-iin Khiid (1654) monasteries were built during this period.

Construction of temples in the renaissance tradition continued into the 18th, 19th and early 20th centuries. Ishbaljir (1709–1788) compared building proportions to the proportions of the human body in "Exquisite Flower Beads", and Agvaanhaidav (1779–1838) described the process of building a Maitreya temple. Agvaanceren (1785–1849) wrote "Aahar shaahar" ("Building and Repairing Temples"). Translations of the Kangyur were also used by Mongolian architects.

The Züün Huree (1711), Amarbayasgalant (1727) and Manjusri Hiid (1733) monasteries were built during this period. The mobile monastery Ihe Huree, founded for Zanabazar, settled at its present Ulaanbaatar location in 1779. The wall around Erdene Yuu monastery, with 108 stupas, began construction in 1734.
The temple of the boddhisattva Avalokiteshvara was built from 1911 to 1913 as a symbol of the new, independent Bogdo Khanate of Mongolia. The statue of the boddhisattva, believed to opens the eyes of wisdom in sentient beings, symbolised the Mongolian people's step into modern civilisation.

In the beginning of the 20th century, there were about 800 monasteries throughout the country.
The experimental practice of combining traditional Asian architecture with Russian architecture was explored. The Bogd Khan had his winter palace built as a Russian "horomy". Another example of the combining of Asian and Russian styles is the residence of Khanddorji Wang, a leader of the Mongolian Revolution of 1911. The body of the building is designed as a Russian house, and the top was designed in the Asian style. One of the first European buildings in Mongolia is the 2-storey building housing Zanabazar Museum of Fine Arts, built as a trade centre in 1905.

The October Revolution destroyed much traditional culture, with over 800 monasteries demolished and thousands of lamas purged. The constructivist architecture which flourished in the Soviet Union also took root in Mongolia. The Radio and Postal Communications Committee building, with its pyramid-topped tower, was an example of constructivism. Other examples were the Mongoltrans offices, the Ministry of Internal Affairs and the Military Club.

Downtown Ulaanbaatar was designed by Soviet architects, who developed classicism as Stalinist architecture. The Ministry of Foreign Affairs, the State University, Government House, the Opera House and the State Library exemplify European classicism.

Mongolian architects worked to creatively combine this neoclassicism with traditional Mongolian architecture. The development of downtown Ulaanbaatar continued at the initiative of B. Chimed, who designed the National Theatre, the Natural History Museum and the Ulaanbaatar Hotel. The theatre has the quadratic plane and double-tier marquee roof of Mongolian architecture; it and his other buildings Chimed's use of indigenous traditions in contemporary architecture. This direction was followed by other architects; the Urt Tsagaan (Tourists' Walk) and Ministry of Health by B. Dambiinyam and the Astronomical Observatory, State University Building #2 and Meteorology Building by A. Hishigt are distinct from European architecture.

Mongolian architecture was dictated by economy and mass production during the Nikita Khrushchev and Leonid Brezhnev eras in the Soviet Union. The early 1960s were characterised by increased Soviet and Chinese investment due to their competition for Mongolian influence, and the competition resulted in accelerated development. The older districts south of the Middle River (Dund gol) and the Peace Bridge were built by Chinese workers.

The architecture of the 1960s and 1970s included monotonous four-, five- and nine-storey apartment blocks with simple rectangular shapes, dictated by the need for cheap, speedy construction. Hostility between the Soviet Union and China forced Mongolia to take sides, and the country allied with the former (leading to increased Soviet investment). Apartment districts were built around Ulaanbaatar, including south of the Dund gol river, often by Soviet soldiers. New cities were built (Darkhan, Erdenet and Baganuur) during this period.

Brezhnev's 1974 visit was followed by modern housing in Ulaanbaatar's Bayangol district. The housing consists of nine-storey apartment blocks and five V-shaped 12-storey buildings on Ayush Street, similar to Kalinin Avenue in the centre of Moscow. This street is the city's busiest shopping centre.

The monotony of urban architecture was criticised at four successive congresses of the Mongolian Association of Architects beginning in 1972, but no significant improvement was achieved. The early 1980s brought new public buildings, such as the Lenin Museum and the Yalalt Cinema (now the Tengis). The Ethnographical Museum, in the centre of Ulaanbaatar's amusement park, was designed as a Mongolian castle surrounded by walls on an island in an artificial lake. The winter house of the international children's Nairamdal camp was designed as an ocean liner travelling in a sea of mountains. One of the largest monuments of the socialist period is the Palace of Culture. Although it has elements of Mongolian architecture, its basic design is also found in the capitals of many former socialist countries.

Amid a vision of replacing yurts with apartment blocks, the yurt districts were seen as temporary, transient housing. Under socialism the state made little or no effort (except for bathhouses) to develop the yurt districts, which became Mongolian shanty towns.

Perestroika and the transition to democracy induced interest in traditional history and culture and free thinking in the arts and architecture. Nearly the entire population of Mongolia donated toward repairs to the Chenrezig temple in the Gandan Tegchinling monastery and the re-casting of the statue of Boddhisattva Avalokiteshvara. A group of artists and architects led by the actor Bold, an enthusiast for traditional architecture, developed a project to make Ulaanbaatar an Asian city. They began building traditional gates and shades in the Street of Revolutionaries and other streets and in the amusement park. Although the project ended at the beginning of the 1998 Russian financial crisis, Mongolia's Buddhist sangha continued restoring and founding monasteries.

Modern architecture returned as the economy began to recover from the financial crisis. The completion of the tall glass Ardiin Bank building (now hosting the Ulaanbaatar Bank) and the glass Chinggis Khan Hotel complex during the second half of 1990s marked the beginning of a new age in Mongolian architecture.

The Bodhi Tower, built in 2004, consists of two buildings. The one facing Sükhbaatar Square is a four-storey classical building which harmonises with the surrounding 1950s architecture. A high-rise tower, the other building, faces the back street; a similar principle was used in the design of the previous period's Palace of Culture. Another contemporary building is Ulaanbaatar's Narantuul Tower. Hotel Mongolia, in the city's Bayanzürkh district, has a silver-tree fountain at its centre reminiscent of Karakorum.

Prime Minister Tsakhiagiin Elbegdorj appointed a group of professionals to develop a project for a new city at Karakorum. According to the prime minister, the new city would become the capital of Mongolia. After his resignation and the appointment of Miyeegombyn Enkhbold as prime minister, the project was abandoned.

The Xiongnu were a confederation of nomadic tribes from Central Asia with a ruling class of unknown origin and other subjugated tribes. They lived on the Mongolian Plateau between the 3rd century BC and the 460s AD, their territories including modern day Mongolia, southern Siberia, western Manchuria, and the modern Chinese provinces of Inner Mongolia, Gansu, and Xinjiang. The Xiongnu was the first unified empire of nomadic peoples. Relations between early Chinese dynasties and the Xiongnu were complicated and included military conflict, exchanges of tribute and trade, and marriage treaties. When Emperor Qin Shihuang drove them away from the south of the Yellow River, he built the famous Great Wall to prevent the Xiongnu from coming back.

Nomadic empire

Nomadic empires, sometimes also called steppe empires, Central or Inner Asian empires, are the empires erected by the bow-wielding, horse-riding, nomadic peoples in the Eurasian steppe, from classical antiquity (Scythia) to the early modern era (Dzungars). They are the most prominent example of non-sedentary polities.

Some nomadic empires operated by establishing a capital city inside a conquered sedentary state, and then by exploiting the existing bureaucrats and commercial resources of that non-nomadic society. As the pattern is repeated, the originally nomadic dynasty becomes culturally assimilated to the culture of the occupied nation before it is ultimately overthrown. Ibn Khaldun described a similar cycle on a smaller scale in his Asabiyyah theory. A term used for these polities in the early medieval period is khanate (after "khan", the title of their rulers), and after the Mongol conquests also as orda (horde) as in Golden Horde.

The Cimmerians were an ancient Indo-European people living north of the Caucasus and the Sea of Azov as early as 1300 BCE until they were driven southward by the Scythians into Anatolia during the 8th century BC. Linguistically they are usually regarded as Iranian, or possibly Thracian with an Iranian ruling class.Scythia (; Ancient Greek: Σκυθική) was a region of Central Eurasia in classical antiquity, occupied by the Eastern Iranian Scythians, encompassing parts of Eastern Europe east of the Vistula River and Central Asia, with the eastern edges of the region vaguely defined by the Greeks. The Ancient Greeks gave the name Scythia (or Great Scythia) to all the lands north-east of Europe and the northern coast of the Black Sea.
The Scythians – the Greeks' name for this initially nomadic people – inhabited Scythia from at least the 11th century BC to the 2nd century AD.

The Sarmatians (Latin: "Sarmatæ" or "Sauromatæ", Greek: ) were a large confederation of Iranian people during classical antiquity, flourishing from about the 6th century BC to the 4th century AD. They spoke Scythian, an Indo-European language from the Eastern Iranian family. According to authors Arrowsmith, Fellowes and Graves Hansard in their book "A Grammar of Ancient Geography" published in 1832, Sarmatia had two parts, Sarmatia Europea and Sarmatia Asiatica covering a combined area of 503,000 sq mi or 1,302,764 km.
Sarmatians were basically Scythian veterans (Saka, Iazyges, Skolotoi, Parthians...) returning to the Pontic-Caspian steppe after the siege of Nineveh. Many noble families of Polish Szlachta claim a direct descent from Sarmatians, whereby some of their earliest royals, including those of ancient pre-Roman Vindelicia, Boioaria, Hvalvedia, Pannonia and some of the later Piast dynasty derive dubious descent directly from the Aryan Suryavansha (Swarożyce) Ikshvaku dynasty (Jakszyce) and later also from elected Sarmatians.

The Kushan Empire (, "Kushano"; "Kuṣāṇ Rājavaṃśa"; BHS: ""; "Kušan-xšaθr") was a syncretic empire, formed by Yuezhi under the pressure of the Xiongnu), in the Bactrian territories in the early 1st century. It spread to encompass much of Afghanistan, and then the northern parts of the Indian subcontinent at least as far as Saketa and Sarnath near Varanasi (Benares), where inscriptions have been found dating to the era of the Kushan emperor Kanishka the Great.

The Xianbei state or Xianbei confederation was a nomadic empire which existed in modern-day Mongolia, Inner Mongolia, northern Xinjiang, Northeast China, Gansu, Buryatia, Zabaykalsky Krai, Irkutsk Oblast, Tuva, Altai Republic and eastern Kazakhstan from 156–234 AD. Like most ancient peoples known through Chinese historiography, the ethnic makeup of the Xianbei is unclear. The Xianbei were a northern branch of the earlier Donghu and it is likely at least some were proto-Mongols. After it collapsed, the tribe immigrated to China and founded the Northern Wei Dynasty.

The Hephthalites, Ephthalites, Ye-tai, White Huns, or, in Sanskrit, the Sveta Huna, were a confederation of nomadic and settled people in Central Asia who expanded their domain westward in the 5th century. At the height of its power in the first half of the 6th century, the Hephthalite Empire controlled territory in present-day Afghanistan, Turkmenistan, Uzbekistan, Tajikistan, Kyrgyzstan, Kazakhstan, Pakistan, India and China.

The Huns were a confederation of Eurasian tribes from the Steppes of Central Asia. Appearing from beyond the Volga River some years after the middle of the 4th century, they conquered all of eastern Europe, ending up at the border of the Roman Empire in the south, and advancing far into modern day Germany in the north. Their appearance in Europe brought with it great ethnic and political upheaval and may have stimulated the Great Migration. The empire reached its largest size under Attila between 447 and 453.

The Rouran (柔然), Juan Juan (蠕蠕), or Ruru (茹茹) were a confederation of Mongolic speaking nomadic tribes on the northern borders of China from the late 4th century until the late 6th century. They controlled the area of Mongolia from the Manchurian border to Turpan and, perhaps, the east coast of Lake Balkhash, and from the Orkhon River to China Proper.

The Göktürks or Kök-Türks were a Turkic people of ancient North and Central Asia and northwestern China. Under the leadership of Bumin Khan and his sons they established the first known Turkic state around 546, taking the place of the earlier Xiongnu as the main power in the region. They were the first Turkic tribe to use the name "Türk" as a political name. The empire was split into a western and an eastern part around 600, merged again 680, and finally declined after 734.

The Uyghur Empire was a Turkic empire that existed in present-day Mongolia and surrounding areas for about a century between the mid 8th and 9th centuries. It was a tribal confederation under the Orkhon Uyghur nobility. It was established by Kutlug I Bilge Kagan in 744, taking advantage of the power vacuum in the region after the fall of the Gökturk Empire. It collapsed after a Kyrgyz invasion in 840.

The Mongol Empire was the largest contiguous land empire in history at its peak, with an estimated population of over 100 million people. The Mongol Empire was founded by Genghis Khan in 1206, and at its height, it encompassed the majority of the territories from Southeast Asia to Eastern Europe.

After unifying the Turco-Mongol tribes, the Empire expanded through conquests throughout continental Eurasia. During its existence, the Pax Mongolica facilitated cultural exchange and trade on the Silk Route between the East, West, and the Middle East in the period of the 13th and 14th centuries. It had significantly eased communication and commerce across Asia during its height.

After the death of Möngke Khan in 1259, the empire split into four parts (Yuan dynasty, Ilkhanate, Chagatai Khanate and Golden Horde), each of which was ruled by its own Khan, though the Yuan rulers had nominal title of Khagan. After the disintegration of the western khanates and the fall of the Yuan dynasty in China in 1368, the empire finally broke up.

The Timurids, self-designated Gurkānī, were a Turko-Mongol dynasty, established by the warlord Timur in 1370 and lasting until 1506. At its zenith, the Timurid Empire included the whole of Central Asia, Iran and modern Afghanistan, as well as large parts of Mesopotamia and the Caucasus.

Later Mongol khanates such as the Northern Yuan dynasty based in Mongolia and the Dzungar Khanate based in Xinjiang were also nomadic empires. Right after the fall of the Yuan dynasty in 1368, the succeeding Ming dynasty established by Han Chinese rebuilt the Great Wall, which had been begun many hundreds of years earlier to keep the northern nomads out of China proper. During the subsequent centuries the Mongols, who were then based in Mongolia as the Northern Yuan dynasty, tended to continue their independent, nomadic way of life as much as possible. On the other hand, the Dzungars were a confederation of several Oirat tribes who formed and maintained the last horse archer empire from the early 17th century to the middle 18th century. They emerged in the early 17th century to fight the Altan Khan of the Khalkha, the Jasaghtu Khan and their Manchu patrons for dominion and control over the Mongolian people and territories. In 1756 this last nomadic power was dissolved due to the Oirat princes' succession struggle and costly war with the Qing dynasty.

The Qing dynasty is mistakenly confused as a nomadic empire by people who wrongly think that the Manchus were a nomadic people, when in fact they were not nomads, but instead were a sedentary agricultural people who lived in fixed villages, farmed crops, and practiced hunting and mounted archery.

The Sushen used flint headed wooden arrows, farmed, hunted, and fished, and lived in caves and trees. The cognates Sushen or Jichen (稷真) again appear in the "Shan Hai Jing" and "Book of Wei" during the dynastic era referring to Tungusic Mohe tribes of the far northeast. The Mohe enjoyed eating pork, practiced pig farming extensively, and were mainly sedentary, and also used both pig and dog skins for coats. They were predominantly farmers and grew soybean, wheat, millet, and rice, in addition to engaging in hunting.

The Jurchens were sedentary, settled farmers with advanced agriculture. They farmed grain and millet as their cereal crops, grew flax, and raised oxen, pigs, sheep, and horses. Their farming way of life was very different from the pastoral nomadism of the Mongols and the Khitan on the steppes. "At the most", the Jurchen could only be described as "semi-nomadic" while the majority of them were sedentary.

The Manchu way of life (economy) was described as agricultural, farming crops and raising animals on farms. Manchus practiced Slash-and-burn agriculture in the areas north of Shenyang. The Haixi Jurchens were "semi-agricultural, the Jianzhou Jurchens and Maolian (毛怜) Jurchens were sedentary, while hunting and fishing was the way of life of the "Wild Jurchens". Han Chinese society resembled that of the sedentary Jianzhou and Maolian, who were farmers. Hunting, archery on horseback, horsemanship, livestock raising, and sedentary agriculture were all practiced by the Jianzhou Jurchens as part of their culture. In spite of the fact that the Manchus practiced archery on horse back and equestrianism, the Manchu's immediate progenitors practiced sedentary agriculture. Although the Manchus also partook in hunting, they were sedentary. Their primary mode of production was farming while they lived in villages, forts, and towns surrounded by walls. Farming was practiced by their Jurchen Jin predecessors.

For political reasons, the Jurchen leader Nurhaci chose variously to emphasize either differences or similarities in lifestyles with other peoples like the Mongols. Nurhaci said to the Mongols that "The languages of the Chinese and Koreans are different, but their clothing and way of life is the same. It is the same with us Manchus (Jušen) and Mongols. Our languages are different, but our clothing and way of life is the same." Later Nurhaci indicated that the bond with the Mongols was not based in any real shared culture. It was for pragmatic reasons of "mutual opportunism", since Nurhaci said to the Mongols: "You Mongols raise livestock, eat meat and wear pelts. My people till the fields and live on grain. We two are not one country and we have different languages."

Similarly the Indoeuropean dominions, as the Cymmerian, Scythian, Sarmatian or Kushan ones, were not strictly nomadic nor strictly empires.They were organized in small Kšatrapies/Voivodeships sometimes uniting into a bigger Mandala to repel surrounding despotic empires trying to annex their homelands. Only the pastoral part of the population and military troops migrated frequently but most of the population lived in organized agricultural and industrial small scale townships, called in Europe grods, e.g. the oases of Sogdia and Sparia along the Silk Road (Śaka, Tokarians/Tokharians…) and around the Tarim Basin (Tarim mummies, Kingdom of Khotan) or the rural areas of Europe (Sarmatia, Pannonia, Vysperia, Spyrgowa/Spirgovia, Boioaria/Boghoaria…) and Indian subcontinent (Kaśperia, Pandžab…). Due to growing (since the 2nd century BC) number of Turkic nomads and invaders among them, who adopted their horseriding, metallurgy, technologies, clothing and customs, they were also often confused with the later, which mostly occurs in the case of the Scythians (Śaka, Sarmatians, Skolotoi, Iazyges…). In India the Śaka, although known earlier as Śakya as well as Kambojas, forming now the Kushan Empire were confused with the Xionites invading them and were called Mleccha. The Turkic invaders exploit the subdued sedentary Indoeuropeans in agriculture, industry and warfare (Mamluk, Janissaries). In some rare cases the enslaved Indoeuropeans may rise to power, e.g. Aleksandra (Iškandara) Lisowska alias Roxelana.

To the north of China proper, the nomadic Xiongnu chieftain Modu Chanyu (r. 209–174 BC) conquered various tribes inhabiting the eastern portion of the Eurasian Steppe. By the end of his reign, he controlled Manchuria, Mongolia, and the Tarim Basin, subjugating over twenty states east of Samarkand. Emperor Gaozu was troubled about the abundant Han-manufactured iron weapons traded to the Xiongnu along the northern borders, and he established a trade embargo against the group. In retaliation, the Xiongnu invaded what is now Shanxi province, where they defeated the Han forces at Baideng in 200 BC. After negotiations, the "heqin" agreement in 198 BC nominally held the leaders of the Xiongnu and the Han as equal partners in a royal marriage alliance, but the Han were forced to send large amounts of tribute items such as silk clothes, food, and wine to the Xiongnu.

Han dynasty

The Han dynasty (; ) was the second imperial dynasty of China (206 BC–220 AD), preceded by the Qin dynasty (221–206 BC) and succeeded by the Three Kingdoms period (220–280 AD). Spanning over four centuries, the Han period is considered a golden age in Chinese history. To this day, China's majority ethnic group refers to themselves as the "Han Chinese" and the Chinese script is referred to as "Han characters". It was founded by the rebel leader Liu Bang, known posthumously as Emperor Gaozu of Han, and briefly interrupted by the Xin dynasty (9–23 AD) of the former regent Wang Mang. This interregnum separates the Han dynasty into two periods: the Western Han or Former Han (206 BC – 9 AD) and the Eastern Han or Later Han (25–220 AD).

The emperor was at the pinnacle of Han society. He presided over the Han government but shared power with both the nobility and appointed ministers who came largely from the scholarly gentry class. The Han Empire was divided into areas directly controlled by the central government using an innovation inherited from the Qin known as commanderies, and a number of semi-autonomous kingdoms. These kingdoms gradually lost all vestiges of their independence, particularly following the Rebellion of the Seven States. From the reign of Emperor Wu (r. 141–87 BC) onward, the Chinese court officially sponsored Confucianism in education and court politics, synthesized with the cosmology of later scholars such as Dong Zhongshu. This policy endured until the fall of the Qing dynasty in 1911 AD.

The Han dynasty saw an age of economic prosperity and witnessed a significant growth of the money economy first established during the Zhou dynasty (c. 1050–256 BC). The coinage issued by the central government mint in 119 BC remained the standard coinage of China until the Tang dynasty (618–907 AD). The period saw a number of limited institutional innovations. To finance its military campaigns and the settlement of newly conquered frontier territories, the Han government nationalized the private salt and iron industries in 117 BC, but these government monopolies were repealed during the Eastern Han dynasty. Science and technology during the Han period saw significant advances, including the process of papermaking, the nautical steering ship rudder, the use of negative numbers in mathematics, the raised-relief map, the hydraulic-powered armillary sphere for astronomy, and a seismometer for measuring earthquakes employing an inverted pendulum.

The Xiongnu, a nomadic steppe confederation, defeated the Han in 200 BC and forced the Han to submit as a "de facto" inferior and vassal partner, but continued their military raids on the Han borders. Emperor Wu launched several military campaigns against them. The ultimate Han victory in these wars eventually forced the Xiongnu to accept vassal status as Han tributaries. These campaigns expanded Han sovereignty into the Tarim Basin of Central Asia, divided the Xiongnu into two separate confederations, and helped establish the vast trade network known as the Silk Road, which reached as far as the Mediterranean world. The territories north of Han's borders were quickly overrun by the nomadic Xianbei confederation. Emperor Wu also launched successful military expeditions in the south, annexing Nanyue in 111 BC and Dian in 109 BC, and in the Korean Peninsula where the Xuantu and Lelang Commanderies were established in 108 BC. After 92 AD, the palace eunuchs increasingly involved themselves in court politics, engaging in violent power struggles between the various consort clans of the empresses and empresses dowager, causing the Han's ultimate downfall. Imperial authority was also seriously challenged by large Daoist religious societies which instigated the Yellow Turban Rebellion and the Five Pecks of Rice Rebellion. Following the death of Emperor Ling (r. 168–189 AD), the palace eunuchs suffered wholesale massacre by military officers, allowing members of the aristocracy and military governors to become warlords and divide the empire. When Cao Pi, King of Wei, usurped the throne from Emperor Xian, the Han dynasty ceased to exist.

According to the "Records of the Grand Historian", after the collapse of the Qin dynasty the hegemon Xiang Yu appointed Liu Bang as prince of the small fief of Hanzhong, named after its location on the Han River (in modern southwest Shaanxi). Following Liu Bang's victory in the Chu–Han Contention, the resulting Han dynasty was named after the Hanzhong fief.

China's first imperial dynasty was the Qin dynasty (221–207 BC). The Qin unified the Chinese Warring States by conquest, but their empire became unstable after the death of the first emperor Qin Shi Huang. Within four years, the dynasty's authority had collapsed in the face of rebellion. Two former rebel leaders, Xiang Yu (d. 202 BC) of Chu and Liu Bang (d. 195 BC) of Han, engaged in a war to decide who would become hegemon of China, which had fissured into 18 kingdoms, each claiming allegiance to either Xiang Yu or Liu Bang. Although Xiang Yu proved to be a capable commander, Liu Bang defeated him at Battle of Gaixia (202 BC), in modern-day Anhui. Liu Bang assumed the title "emperor" ("huangdi") at the urging of his followers and is known posthumously as Emperor Gaozu (r. 202–195 BC). Chang'an (known today as Xi'an) was chosen as the new capital of the reunified empire under Han.

At the beginning of the Western Han (), also known as the Former Han () dynasty, thirteen centrally controlled commanderies—including the capital region—existed in the western third of the empire, while the eastern two-thirds were divided into ten semi-autonomous kingdoms. To placate his prominent commanders from the war with Chu, Emperor Gaozu enfeoffed some of them as kings. By 157 BC, the Han court had replaced all of these kings with royal Liu family members, since the loyalty of non-relatives to the throne was questioned. After several insurrections by Han kings—the largest being the Rebellion of the Seven States in 154 BC—the imperial court enacted a series of reforms beginning in 145 BC limiting the size and power of these kingdoms and dividing their former territories into new centrally controlled commanderies. Kings were no longer able to appoint their own staff; this duty was assumed by the imperial court. Kings became nominal heads of their fiefs and collected a portion of tax revenues as their personal incomes. The kingdoms were never entirely abolished and existed throughout the remainder of Western and Eastern Han.

Despite the tribute and a negotiation between Laoshang Chanyu (r. 174–160 BC) and Emperor Wen (r. 180–157 BC) to reopen border markets, many of the Chanyu's Xiongnu subordinates chose not to obey the treaty and periodically raided Han territories south of the Great Wall for additional goods. In a court conference assembled by Emperor Wu (r. 141–87 BC) in 135 BC, the majority consensus of the ministers was to retain the "heqin" agreement. Emperor Wu accepted this, despite continuing Xiongnu raids. However, a court conference the following year convinced the majority that a limited engagement at Mayi involving the assassination of the Chanyu would throw the Xiongnu realm into chaos and benefit the Han. When this plot failed in 133 BC, Emperor Wu launched a series of massive military invasions into Xiongnu territory. The assault culminated in 119 BC at the Battle of Mobei, where the Han commanders Huo Qubing (d. 117 BC) and Wei Qing (d. 106 BC) forced the Xiongnu court to flee north of the Gobi Desert.

After Wu's reign, Han forces continued to prevail against the Xiongnu. The Xiongnu leader Huhanye Chanyu (呼韓邪) (r. 58–31 BC) finally submitted to Han as a tributary vassal in 51 BC. His rival claimant to the throne, Zhizhi Chanyu (r. 56–36 BC), was killed by Chen Tang and Gan Yanshou (甘延壽/甘延寿) at the Battle of Zhizhi, in modern Taraz, Kazakhstan.

In 121 BC, Han forces expelled the Xiongnu from a vast territory spanning the Hexi Corridor to Lop Nur. They repelled a joint Xiongnu-Qiang invasion of this northwestern territory in 111 BC. In that year, the Han court established four new frontier commanderies in this region: Jiuquan, Zhangyi, Dunhuang, and Wuwei. The majority of people on the frontier were soldiers. On occasion, the court forcibly moved peasant farmers to new frontier settlements, along with government-owned slaves and convicts who performed hard labor. The court also encouraged commoners, such as farmers, merchants, landowners, and hired laborers, to voluntarily migrate to the frontier.

Even before Han's expansion into Central Asia, diplomat Zhang Qian's travels from 139 to 125 BC had established Chinese contacts with many surrounding civilizations. Zhang encountered Dayuan (Fergana), Kangju (Sogdiana), and Daxia (Bactria, formerly the Greco-Bactrian Kingdom); he also gathered information on Shendu (Indus River valley of North India) and Anxi (the Parthian Empire). All of these countries eventually received Han embassies. These connections marked the beginning of the Silk Road trade network that extended to the Roman Empire, bringing Han items like silk to Rome and Roman goods such as glasswares to China.

From roughly 115 to 60 BC, Han forces fought the Xiongnu over control of the oasis city-states in the Tarim Basin. Han was eventually victorious and established the Protectorate of the Western Regions in 60 BC, which dealt with the region's defense and foreign affairs. The Han also expanded southward. The naval conquest of Nanyue in 111 BC expanded the Han realm into what are now modern Guangdong, Guangxi, and northern Vietnam. Yunnan was brought into the Han realm with the conquest of the Dian Kingdom in 109 BC, followed by parts of the Korean Peninsula with the Han conquest of Gojoseon and colonial establishments of Xuantu Commandery and Lelang Commandery in 108 BC. In China's first known nationwide census taken in 2 AD, the population was registered as having 57,671,400 individuals in 12,366,470 households.

To pay for his military campaigns and colonial expansion, Emperor Wu nationalized several private industries. He created central government monopolies administered largely by former merchants. These monopolies included salt, iron, and liquor production, as well as bronze-coin currency. The liquor monopoly lasted only from 98 to 81 BC, and the salt and iron monopolies were eventually abolished in early Eastern Han. The issuing of coinage remained a central government monopoly throughout the rest of the Han dynasty. The government monopolies were eventually repealed when a political faction known as the Reformists gained greater influence in the court. The Reformists opposed the Modernist faction that had dominated court politics in Emperor Wu's reign and during the subsequent regency of Huo Guang (d. 68 BC). The Modernists argued for an aggressive and expansionary foreign policy supported by revenues from heavy government intervention in the private economy. The Reformists, however, overturned these policies, favoring a cautious, non-expansionary approach to foreign policy, frugal budget reform, and lower tax-rates imposed on private entrepreneurs.

Wang Zhengjun (71 BC–13 AD) was first empress, then empress dowager, and finally grand empress dowager during the reigns of the Emperors Yuan (r. 49–33 BC), Cheng (r. 33–7 BC), and Ai (r. 7–1 BC), respectively. During this time, a succession of her male relatives held the title of regent. Following the death of Ai, Wang Zhengjun's nephew Wang Mang (45 BC–23 AD) was appointed regent as Marshall of State on 16 August under Emperor Ping (r. 1 BC–6 AD). When Ping died on 3 February 6 AD, Ruzi Ying (d. 25 AD) was chosen as the heir and Wang Mang was appointed to serve as acting emperor for the child. Wang promised to relinquish his control to Liu Ying once he came of age. Despite this promise, and against protest and revolts from the nobility, Wang Mang claimed on 10 January that the divine Mandate of Heaven called for the end of the Han dynasty and the beginning of his own: the Xin dynasty (9–23 AD).

Wang Mang initiated a series of major reforms that were ultimately unsuccessful. These reforms included outlawing slavery, nationalizing land to equally distribute between households, and introducing new currencies, a change which debased the value of coinage. Although these reforms provoked considerable opposition, Wang's regime met its ultimate downfall with the massive floods of c. 3 AD and 11 AD. Gradual silt buildup in the Yellow River had raised its water level and overwhelmed the flood control works. The Yellow River split into two new branches: one emptying to the north and the other to the south of the Shandong Peninsula, though Han engineers managed to dam the southern branch by 70 AD.

The flood dislodged thousands of peasant farmers, many of whom joined roving bandit and rebel groups such as the Red Eyebrows to survive. Wang Mang's armies were incapable of quelling these enlarged rebel groups. Eventually, an insurgent mob forced their way into the Weiyang Palace and killed Wang Mang.

The Gengshi Emperor (r. 23–25 AD), a descendant of Emperor Jing (r. 157–141 BC), attempted to restore the Han dynasty and occupied Chang'an as his capital. However, he was overwhelmed by the Red Eyebrow rebels who deposed, assassinated, and replaced him with the puppet monarch Liu Penzi. Gengshi's brother Liu Xiu, known posthumously as Emperor Guangwu (r. 25–57 AD), after distinguishing himself at the Battle of Kunyang in 23 AD, was urged to succeed Gengshi as emperor.

Under Guangwu's rule the Han Empire was restored. Guangwu made Luoyang his capital in 25 AD, and by 27 AD his officers Deng Yu and Feng Yi had forced the Red Eyebrows to surrender and executed their leaders for treason. From 26 until 36 AD, Emperor Guangwu had to wage war against other regional warlords who claimed the title of emperor; when these warlords were defeated, China reunified under the Han.

The period between the foundation of the Han dynasty and Wang Mang's reign is known as the Western Han () or Former Han () (206 BC–9 AD). During this period the capital was at Chang'an (modern Xi'an). From the reign of Guangwu the capital was moved eastward to Luoyang. The era from his reign until the fall of Han is known as the Eastern Han or Later Han (25–220 AD).

The Eastern Han (), also known as the Later Han (), formally began on 5 August 25, when Liu Xiu became Emperor Guangwu of Han. During the widespread rebellion against Wang Mang, the state of Goguryeo was free to raid Han's Korean commanderies; Han did not reaffirm its control over the region until AD 30. The Trưng Sisters of Vietnam rebelled against Han in AD 40. Their rebellion was crushed by Han general Ma Yuan (d. AD 49) in a campaign from AD 42–43. Wang Mang renewed hostilities against the Xiongnu, who were estranged from Han until their leader Bi (比), a rival claimant to the throne against his cousin Punu (蒲奴), submitted to Han as a tributary vassal in AD 50. This created two rival Xiongnu states: the Southern Xiongnu led by Bi, an ally of Han, and the Northern Xiongnu led by Punu, an enemy of Han.

During the turbulent reign of Wang Mang, China lost control over the Tarim Basin, which was conquered by the Northern Xiongnu in AD 63 and used as a base to invade the Hexi Corridor in Gansu. Dou Gu (d. 88 AD) defeated the Northern Xiongnu at the Battle of Yiwulu in AD 73, evicting them from Turpan and chasing them as far as Lake Barkol before establishing a garrison at Hami. After the new Protector General of the Western Regions Chen Mu (d. AD 75) was killed by allies of the Xiongnu in Karasahr and Kucha, the garrison at Hami was withdrawn. At the Battle of Ikh Bayan in AD 89, Dou Xian (d. AD 92) defeated the Northern Xiongnu chanyu who then retreated into the Altai Mountains. After the Northern Xiongnu fled into the Ili River valley in AD 91, the nomadic Xianbei occupied the area from the borders of the Buyeo Kingdom in Manchuria to the Ili River of the Wusun people. The Xianbei reached their apogee under Tanshihuai (檀石槐) (d. AD 180), who consistently defeated Chinese armies. However, Tanshihuai's confederation disintegrated after his death.

Ban Chao (d. AD 102) enlisted the aid of the Kushan Empire, occupying the area of modern India, Pakistan, Afghanistan, and Tajikistan, to subdue Kashgar and its ally Sogdiana. When a request by Kushan ruler Vima Kadphises (r. c. 90–c. 100 AD) for a marriage alliance with the Han was rejected in AD 90, he sent his forces to Wakhan (Afghanistan) to attack Ban Chao. The conflict ended with the Kushans withdrawing because of lack of supplies. In AD 91, the office of Protector General of the Western Regions was reinstated when it was bestowed on Ban Chao.
Foreign travelers to Eastern-Han China include Buddhist monks who translated works into Chinese, such as An Shigao from Parthia, and Lokaksema from Kushan-era Gandhara, India. In addition to tributary relations with the Kushans, the Han Empire received gifts from the Parthian Empire, from a king in modern Burma, from a ruler in Japan, and initiated an unsuccessful mission to Daqin (Rome) in AD 97 with Gan Ying as emissary. A Roman embassy of Emperor Marcus Aurelius (r. 161–180 AD) is recorded in the "Weilüe" and "Hou Hanshu" to have reached the court of Emperor Huan of Han (r. AD 146–168) in AD 166, yet Rafe de Crespigny asserts that this was most likely a group of Roman merchants. In addition to Roman glasswares and coins found in China, Roman medallions from the reign of Antoninus Pius and his adopted son Marcus Aurelius have been found at Óc Eo in Vietnam. This was near the commandery of Rinan (also Jiaozhi) where Chinese sources claim the Romans first landed, as well as embassies from Tianzhu (in northern India) in the years 159 and 161. Óc Eo is also thought to be the port city "Cattigara" described by Ptolemy in his "Geography" (c. 150 AD) as lying east of the Golden Chersonese (Malay Peninsula) along the "Magnus Sinus" (i.e. Gulf of Thailand and South China Sea), where a Greek sailor had visited.
Emperor Zhang's (r. 75–88 AD) reign came to be viewed by later Eastern Han scholars as the high point of the dynastic house. Subsequent reigns were increasingly marked by eunuch intervention in court politics and their involvement in the violent power struggles of the imperial consort clans. With the aid of the eunuch Zheng Zhong (d. 107 AD), Emperor He (r. 88–105 AD) had Empress Dowager Dou (d. 97 AD) put under house arrest and her clan stripped of power. This was in revenge for Dou's purging of the clan of his natural mother—Consort Liang—and then concealing her identity from him. After Emperor He's death, his wife Empress Deng Sui (d. 121 AD) managed state affairs as the regent empress dowager during a turbulent financial crisis and widespread Qiang rebellion that lasted from 107 to 118 AD.

When Empress Dowager Deng died, Emperor An (r. 106–125 AD) was convinced by the accusations of the eunuchs Li Run () and Jiang Jing () that Deng and her family had planned to depose him. An dismissed Deng's clan members from office, exiled them and forced many to commit suicide. After An's death, his wife, Empress Dowager Yan (d. 126 AD) placed the child Marquess of Beixiang on the throne in an attempt to retain power within her family. However, palace eunuch Sun Cheng (d. 132 AD) masterminded a successful overthrow of her regime to enthrone Emperor Shun of Han (r. 125–144 AD). Yan was placed under house arrest, her relatives were either killed or exiled, and her eunuch allies were slaughtered. The regent Liang Ji (d. 159 AD), brother of Empress Liang Na (d. 150 AD), had the brother-in-law of Consort Deng Mengnü (later empress) (d. 165 AD) killed after Deng Mengnü resisted Liang Ji's attempts to control her. Afterward, Emperor Huan employed eunuchs to depose Liang Ji, who was then forced to commit suicide.
Students from the Imperial University organized a widespread student protest against the eunuchs of Emperor Huan's court. Huan further alienated the bureaucracy when he initiated grandiose construction projects and hosted thousands of concubines in his harem at a time of economic crisis. Palace eunuchs imprisoned the official Li Ying () and his associates from the Imperial University on a dubious charge of treason. In 167 AD, the Grand Commandant Dou Wu (d. 168 AD) convinced his son-in-law, Emperor Huan, to release them. However the emperor permanently barred Li Ying and his associates from serving in office, marking the beginning of the Partisan Prohibitions.

Following Huan's death, Dou Wu and the Grand Tutor Chen Fan () (d. 168 AD) attempted a coup d'état against the eunuchs Hou Lan (d. 172 AD), Cao Jie (d. 181 AD), and Wang Fu (). When the plot was uncovered, the eunuchs arrested Empress Dowager Dou (d. 172 AD) and Chen Fan. General Zhang Huan () favored the eunuchs. He and his troops confronted Dou Wu and his retainers at the palace gate where each side shouted accusations of treason against the other. When the retainers gradually deserted Dou Wu, he was forced to commit suicide.

Under Emperor Ling (r. 168–189 AD) the eunuchs had the partisan prohibitions renewed and expanded, while also auctioning off top government offices. Many affairs of state were entrusted to the eunuchs Zhao Zhong (d. 189 AD) and Zhang Rang (d. 189 AD) while Emperor Ling spent much of his time roleplaying with concubines and participating in military parades.

The Partisan Prohibitions were repealed during the Yellow Turban Rebellion and Five Pecks of Rice Rebellion in 184 AD, largely because the court did not want to continue to alienate a significant portion of the gentry class who might otherwise join the rebellions. The Yellow Turbans and Five-Pecks-of-Rice adherents belonged to two different hierarchical Daoist religious societies led by faith healers Zhang Jue (d. 184 AD) and Zhang Lu (d. 216 AD), respectively. Zhang Lu's rebellion, in modern northern Sichuan and southern Shaanxi, was not quelled until 215 AD. Zhang Jue's massive rebellion across eight provinces was annihilated by Han forces within a year, however the following decades saw much smaller recurrent uprisings. Although the Yellow Turbans were defeated, many generals appointed during the crisis never disbanded their assembled militia forces and used these troops to amass power outside of the collapsing imperial authority.

General-in-Chief He Jin (d. 189 AD), half-brother to Empress He (d. 189 AD), plotted with Yuan Shao (d. 202 AD) to overthrow the eunuchs by having several generals march to the outskirts of the capital. There, in a written petition to Empress He, they demanded the eunuchs' execution. After a period of hesitation, Empress He consented. When the eunuchs discovered this, however, they had her brother He Miao () rescind the order. The eunuchs assassinated He Jin on September 22, 189 AD. Yuan Shao then besieged Luoyang's Northern Palace while his brother Yuan Shu (d. 199 AD) besieged the Southern Palace. On September 25 both palaces were breached and approximately two thousand eunuchs were killed. Zhang Rang had previously fled with Emperor Shao (r. 189 AD) and his brother Liu Xie—the future Emperor Xian of Han (r. 189–220 AD). While being pursued by the Yuan brothers, Zhang committed suicide by jumping into the Yellow River.
General Dong Zhuo (d. 192 AD) found the young emperor and his brother wandering in the countryside. He escorted them safely back to the capital and was made Minister of Works, taking control of Luoyang and forcing Yuan Shao to flee. After Dong Zhuo demoted Emperor Shao and promoted his brother Liu Xie as Emperor Xian, Yuan Shao led a coalition of former officials and officers against Dong, who burned Luoyang to the ground and resettled the court at Chang'an in May 191 AD. Dong Zhuo later poisoned Emperor Shao.

Dong was killed by his adopted son Lü Bu (d. 198 AD) in a plot hatched by Wang Yun (d. 192 AD). Emperor Xian fled from Chang'an in 195 AD to the ruins of Luoyang. Xian was persuaded by Cao Cao (155–220 AD), then Governor of Yan Province in modern western Shandong and eastern Henan, to move the capital to Xuchang in 196 AD.

Yuan Shao challenged Cao Cao for control over the emperor. Yuan's power was greatly diminished after Cao defeated him at the Battle of Guandu in 200 AD. After Yuan died, Cao killed Yuan Shao's son Yuan Tan (173–205 AD), who had fought with his brothers over the family inheritance. His brothers Yuan Shang and Yuan Xi were killed in 207 AD by Gongsun Kang (d. 221 AD), who sent their heads to Cao Cao.

After Cao's defeat at the naval Battle of Red Cliffs in 208 AD, China was divided into three spheres of influence, with Cao Cao dominating the north, Sun Quan (182–252 AD) dominating the south, and Liu Bei (161–223 AD) dominating the west. Cao Cao died in March 220 AD. By December his son Cao Pi (187–226 AD) had Emperor Xian relinquish the throne to him and is known posthumously as Emperor Wen of Wei. This formally ended the Han dynasty and initiated an age of conflict between three states: Cao Wei, Eastern Wu, and Shu Han.

In the hierarchical social order, the emperor was at the apex of Han society and government. However the emperor was often a minor, ruled over by a regent such as the empress dowager or one of her male relatives. Ranked immediately below the emperor were the kings who were of the same Liu family clan. The rest of society, including nobles lower than kings and all commoners excluding slaves belonged to one of twenty ranks ("ershi gongcheng" ).

Each successive rank gave its holder greater pensions and legal privileges. The highest rank, of full marquess, came with a state pension and a territorial fiefdom. Holders of the rank immediately below, that of ordinary marquess, received a pension, but had no territorial rule. Officials who served in government belonged to the wider commoner social class and were ranked just below nobles in social prestige. The highest government officials could be enfeoffed as marquesses. By the Eastern Han period, local elites of unattached scholars, teachers, students, and government officials began to identify themselves as members of a larger, nationwide gentry class with shared values and a commitment to mainstream scholarship. When the government became noticeably corrupt in mid-to-late Eastern Han, many gentrymen even considered the cultivation of morally grounded personal relationships more important than serving in public office.

The farmer, or specifically the small landowner-cultivator, was ranked just below scholars and officials in the social hierarchy. Other agricultural cultivators were of a lower status, such as tenants, wage laborers, and in rare cases slaves. Artisans, technicians, tradespeople and craftsmen had a legal and socioeconomic status between that of owner-cultivator farmers and common merchants. State-registered merchants, who were forced by law to wear white-colored clothes and pay high commercial taxes, were considered by the gentry as social parasites with a contemptible status. These were often petty shopkeepers of urban marketplaces; merchants such as industrialists and itinerant traders working between a network of cities could avoid registering as merchants and were often wealthier and more powerful than the vast majority of government officials. Wealthy landowners, such as nobles and officials, often provided lodging for retainers who provided valuable work or duties, sometimes including fighting bandits or riding into battle. Unlike slaves, retainers could come and go from their master's home as they pleased. Medical physicians, pig breeders, and butchers had a fairly high social status, while occultist diviners, runners, and messengers had low status.

The Han-era family was patrilineal and typically had four to five nuclear family members living in one household. Multiple generations of extended family members did not occupy the same house, unlike families of later dynasties. According to Confucian family norms, various family members were treated with different levels of respect and intimacy. For example, there were different accepted time frames for mourning the death of a father versus a paternal uncle.

Marriages were highly ritualized, particularly for the wealthy, and included many important steps. The giving of betrothal gifts, known as bridewealth and dowry, were especially important. A lack of either was considered dishonorable and the woman would have been seen not as a wife, but as a concubine. Arranged marriages were normal, with the father's input on his offspring's spouse being considered more important than the mother's. Monogamous marriages were also normal, although nobles and high officials were wealthy enough to afford and support concubines as additional lovers. Under certain conditions dictated by custom, not law, both men and women were able to divorce their spouses and remarry. However, a woman who had been widowed continued to belong to her husband's family after his death. In order to remarry, the widow would have to be returned to her family in exchange for a ransom fee. Her children would not be allowed to go with her.

Apart from the passing of noble titles or ranks, inheritance practices did not involve primogeniture; each son received an equal share of the family property. Unlike the practice in later dynasties, the father usually sent his adult married sons away with their portions of the family fortune. Daughters received a portion of the family fortune through their marriage dowries, though this was usually much less than the shares of sons. A different distribution of the remainder could be specified in a will, but it is unclear how common this was.

Women were expected to obey the will of their father, then their husband, and then their adult son in old age. However, it is known from contemporary sources that there were many deviations to this rule, especially in regard to mothers over their sons, and empresses who ordered around and openly humiliated their fathers and brothers. Women were exempt from the annual corvée labor duties, but often engaged in a range of income-earning occupations aside from their domestic chores of cooking and cleaning.

The most common occupation for women was weaving clothes for the family, sale at market or for large textile enterprises that employed hundreds of women. Other women helped on their brothers' farms or became singers, dancers, sorceresses, respected medical physicians, and successful merchants who could afford their own silk clothes. Some women formed spinning collectives, aggregating the resources of several different families.

The early Western Han court simultaneously accepted the philosophical teachings of Legalism, Huang-Lao Daoism, and Confucianism in making state decisions and shaping government policy. However, the Han court under Emperor Wu gave Confucianism exclusive patronage. He abolished all academic chairs or erudites ("bóshì" 博士) not dealing with the Confucian Five Classics in 136 BC and encouraged nominees for office to receive a Confucian-based education at the Imperial University that he established in 124 BC. Unlike the original ideology espoused by Confucius, or Kongzi (551–479 BC), Han Confucianism in Emperor Wu's reign was the creation of Dong Zhongshu (179–104 BC). Dong was a scholar and minor official who aggregated the ethical Confucian ideas of ritual, filial piety, and harmonious relationships with five phases and yin-yang cosmologies. Much to the interest of the ruler, Dong's synthesis justified the imperial system of government within the natural order of the universe. The Imperial University grew in importance as the student body grew to over 30,000 by the 2nd century AD. A Confucian-based education was also made available at commandery-level schools and private schools opened in small towns, where teachers earned respectable incomes from tuition payments.

Some important texts were created and studied by scholars. Philosophical works written by Yang Xiong (53 BC–18 AD), Huan Tan (43 BC–28 AD), Wang Chong (27–100 AD), and Wang Fu (78–163 AD) questioned whether human nature was innately good or evil and posed challenges to Dong's universal order. The "Records of the Grand Historian" by Sima Tan (d. 110 BC) and his son Sima Qian (145–86 BC) established the standard model for all of imperial China's Standard Histories, such as the "Book of Han" written by Ban Biao (3–54 AD), his son Ban Gu (32–92 AD), and his daughter Ban Zhao (45–116 AD). There were dictionaries such as the "Shuowen Jiezi" by Xu Shen (c. 58–c. 147 AD) and the "Fangyan" by Yang Xiong. Biographies on important figures were written by various gentrymen. Han dynasty poetry was dominated by the "fu" genre, which achieved its greatest prominence during the reign of Emperor Wu.

Han scholars such as Jia Yi (201–169 BC) portrayed the previous Qin dynasty as a brutal regime. However, archaeological evidence from Zhangjiashan and Shuihudi reveal that many of the statutes in the Han law code compiled by Chancellor Xiao He (d. 193 BC) were derived from Qin law.

Various cases for rape, physical abuse and murder were prosecuted in court. Women, although usually having fewer rights by custom, were allowed to level civil and criminal charges against men. While suspects were jailed, convicted criminals were never imprisoned. Instead, punishments were commonly monetary fines, periods of forced hard labor for convicts, and the penalty of death by beheading. Early Han punishments of torturous mutilation were borrowed from Qin law. A series of reforms abolished mutilation punishments with progressively less-severe beatings by the bastinado.

Acting as a judge in lawsuits was one of many duties of the county magistrate and Administrators of commanderies. Complex, high-profile or unresolved cases were often deferred to the Minister of Justice in the capital or even the emperor. In each Han county was several districts, each overseen by a chief of police. Order in the cities was maintained by government officers in the marketplaces and constables in the neighborhoods.

The most common staple crops consumed during Han were wheat, barley, foxtail millet, proso millet, rice, and beans. Commonly eaten fruits and vegetables included chestnuts, pears, plums, peaches, melons, apricots, strawberries, red bayberries, jujubes, calabash, bamboo shoots, mustard plant and taro. Domesticated animals that were also eaten included chickens, Mandarin ducks, geese, cows, sheep, pigs, camels and dogs (various types were bred specifically for food, while most were used as pets). Turtles and fish were taken from streams and lakes. Commonly hunted game, such as owl, pheasant, magpie, sika deer, and Chinese bamboo partridge were consumed. Seasonings included sugar, honey, salt and soy sauce. Beer and wine were regularly consumed.

The types of clothing worn and the materials used during the Han period depended upon social class. Wealthy folk could afford silk robes, skirts, socks, and mittens, coats made of badger or fox fur, duck plumes, and slippers with inlaid leather, pearls, and silk lining. Peasants commonly wore clothes made of hemp, wool, and ferret skins.

Families throughout Han China made ritual sacrifices of animals and food to deities, spirits, and ancestors at temples and shrines. They believed that these items could be utilized by those in the spiritual realm. It was thought that each person had a two-part soul: the spirit-soul ("hun" 魂) which journeyed to the afterlife paradise of immortals ("xian"), and the body-soul ("po" 魄) which remained in its grave or tomb on earth and was only reunited with the spirit-soul through a ritual ceremony.

In addition to his many other roles, the emperor acted as the highest priest in the land who made sacrifices to Heaven, the main deities known as the Five Powers, and the spirits ("shen" 神) of mountains and rivers. It was believed that the three realms of Heaven, Earth, and Mankind were linked by natural cycles of yin and yang and the five phases. If the emperor did not behave according to proper ritual, ethics, and morals, he could disrupt the fine balance of these cosmological cycles and cause calamities such as earthquakes, floods, droughts, epidemics, and swarms of locusts.
It was believed that immortality could be achieved if one reached the lands of the Queen Mother of the West or Mount Penglai. Han-era Daoists assembled into small groups of hermits who attempted to achieve immortality through breathing exercises, sexual techniques and use of medical elixirs. By the 2nd century AD, Daoists formed large hierarchical religious societies such as the Way of the Five Pecks of Rice. Its followers believed that the sage-philosopher Laozi (fl. 6th century BC) was a holy prophet who would offer salvation and good health if his devout followers would confess their sins, ban the worship of unclean gods who accepted meat sacrifices and chant sections of the "Daodejing".

Buddhism first entered China during the Eastern Han and was first mentioned in 65 AD. Liu Ying (d. 71 AD), a half-brother to Emperor Ming of Han (r. 57–75 AD), was one of its earliest Chinese adherents, although Chinese Buddhism at this point was heavily associated with Huang-Lao Daoism. China's first known Buddhist temple, the White Horse Temple, was constructed outside the wall of the capital, Luoyang, during Emperor Ming's reign. Important Buddhist canons were translated into Chinese during the 2nd century AD, including the "Sutra of Forty-two Chapters", "Perfection of Wisdom", "Shurangama Sutra", and "Pratyutpanna Sutra".

In Han government, the emperor was the supreme judge and lawgiver, the commander-in-chief of the armed forces and sole designator of official nominees appointed to the top posts in central and local administrations; those who earned a 600-bushel salary-rank or higher. Theoretically, there were no limits to his power. However, state organs with competing interests and institutions such as the court conference ("tingyi" 廷議)—where ministers were convened to reach majority consensus on an issue—pressured the emperor to accept the advice of his ministers on policy decisions. If the emperor rejected a court conference decision, he risked alienating his high ministers. Nevertheless, emperors sometimes did reject the majority opinion reached at court conferences.

Below the emperor were his cabinet members known as the Three Councillors of State ("San gong" 三公). These were the Chancellor or Minister over the Masses ("Chengxiang" 丞相 or "Da situ" 大司徒), the Imperial Counselor or Excellency of Works ("Yushi dafu" 御史大夫 or "Da sikong" 大司空), and Grand Commandant or Grand Marshal ("Taiwei" 太尉 or "Da sima" 大司馬).

The Chancellor, whose title was changed to 'Minister over the Masses' in 8 BC, was chiefly responsible for drafting the government budget. The Chancellor's other duties included managing provincial registers for land and population, leading court conferences, acting as judge in lawsuits and recommending nominees for high office. He could appoint officials below the salary-rank of 600 bushels.

The Imperial Counselor's chief duty was to conduct disciplinary procedures for officials. He shared similar duties with the Chancellor, such as receiving annual provincial reports. However, when his title was changed to Minister of Works in 8 BC, his chief duty became oversight of public works projects.

The Grand Commandant, whose title was changed to Grand Marshal in 119 BC before reverting to Grand Commandant in 51 AD, was the irregularly posted commander of the military and then regent during the Western Han period. In the Eastern Han era he was chiefly a civil official who shared many of the same censorial powers as the other two Councillors of State.

Ranked below the Three Councillors of State were the Nine Ministers ("Jiu qing" 九卿), who each headed a specialized ministry. The Minister of Ceremonies ("Taichang" 太常) was the chief official in charge of religious rites, rituals, prayers and the maintenance of ancestral temples and altars. The Minister of the Household ("Guang lu xun" 光祿勳) was in charge of the emperor's security within the palace grounds, external imperial parks and wherever the emperor made an outing by chariot. The Minister of the Guards ("Weiwei" 衛尉) was responsible for securing and patrolling the walls, towers, and gates of the imperial palaces. The Minister Coachman ("Taipu" 太僕) was responsible for the maintenance of imperial stables, horses, carriages and coach-houses for the emperor and his palace attendants, as well as the supply of horses for the armed forces. The Minister of Justice ("Tingwei" 廷尉) was the chief official in charge of upholding, administering, and interpreting the law. The Minister Herald ("Da honglu" 大鴻臚) was the chief official in charge of receiving honored guests at the imperial court, such as nobles and foreign ambassadors. The Minister of the Imperial Clan ("Zongzheng" 宗正) oversaw the imperial court's interactions with the empire's nobility and extended imperial family, such as granting fiefs and titles. The Minister of Finance ("Da sinong" 大司農) was the treasurer for the official bureaucracy and the armed forces who handled tax revenues and set standards for units of measurement. The Minister Steward ("Shaofu" 少府) served the emperor exclusively, providing him with entertainment and amusements, proper food and clothing, medicine and physical care, valuables and equipment.

In the Han dynasty, excluding kingdoms and marquessates, was divided, in descending order of size, into political units of provinces ("zhou"), commanderies ("jun"), and counties ("xian"). A county was divided into several districts, the latter composed of a group of hamlets, each containing about a hundred families.

The heads of provinces, whose official title was changed from Inspector to Governor and vice versa several times during Han, were responsible for inspecting several commandery-level and kingdom-level administrations. On the basis of their reports, the officials in these local administrations would be promoted, demoted, dismissed or prosecuted by the imperial court.

A governor could take various actions without permission from the imperial court. The lower-ranked inspector had executive powers only during times of crisis, such as raising militias across the commanderies under his jurisdiction to suppress a rebellion.

A commandery consisted of a group of counties, and was headed by an Administrator. He was the top civil and military leader of the commandery and handled defense, lawsuits, seasonal instructions to farmers and recommendations of nominees for office sent annually to the capital in a quota system first established by Emperor Wu. The head of a large county of about 10,000 households was called a Prefect, while the heads of smaller counties were called Chiefs, and both could be referred to as Magistrates. A Magistrate maintained law and order in his county, registered the populace for taxation, mobilized commoners for annual corvée duties, repaired schools and supervised public works.

Kingdoms—roughly the size of commanderies—were ruled exclusively by the emperor's male relatives as semi-autonomous fiefdoms. Before 157 BC some kingdoms were ruled by non-relatives, granted to them in return for their services to Emperor Gaozu. The administration of each kingdom was very similar to that of the central government. Although the emperor appointed the Chancellor of each kingdom, kings appointed all the remaining civil officials in their fiefs.

However, in 145 BC, after several insurrections by the kings, Emperor Jing removed the kings' rights to appoint officials whose salaries were higher than 400 bushels. The Imperial Counselors and Nine Ministers (excluding the Minister Coachman) of every kingdom were abolished, although the Chancellor was still appointed by the central government.

With these reforms, kings were reduced to being nominal heads of their fiefs, gaining a personal income from only a portion of the taxes collected in their kingdom. Similarly, the officials in the administrative staff of a full marquess's fief were appointed by the central government. A marquess's Chancellor was ranked as the equivalent of a county Prefect. Like a king, the marquess collected a portion of the tax revenues in his fief as personal income.
At the beginning of the Han dynasty, every male commoner aged twenty-three was liable for conscription into the military. The minimum age for the military draft was reduced to twenty after Emperor Zhao's (r. 87–74 BC) reign. Conscripted soldiers underwent one year of training and one year of service as non-professional soldiers. The year of training was served in one of three branches of the armed forces: infantry, cavalry or navy. The year of active service was served either on the frontier, in a king's court or under the Minister of the Guards in the capital. A small professional (paid) standing army was stationed near the capital.

During the Eastern Han, conscription could be avoided if one paid a commutable tax. The Eastern Han court favored the recruitment of a volunteer army. The volunteer army comprised the Southern Army ("Nanjun" 南軍), while the standing army stationed in and near the capital was the Northern Army ("Beijun" 北軍). Led by Colonels ("Xiaowei" 校尉), the Northern Army consisted of five regiments, each composed of several thousand soldiers. When central authority collapsed after 189 AD, wealthy landowners, members of the aristocracy/nobility, and regional military-governors relied upon their retainers to act as their own personal troops ("buqu" 部曲).

During times of war, the volunteer army was increased, and a much larger militia was raised across the country to supplement the Northern Army. In these circumstances, a General ("Jiangjun" 將軍) led a division, which was divided into regiments led by Colonels and sometimes Majors ("Sima" 司馬). Regiments were divided into companies and led by Captains. Platoons were the smallest units of soldiers.

The Han dynasty inherited the "ban liang" coin type from the Qin. In the beginning of the Han, Emperor Gaozu closed the government mint in favor of private minting of coins. This decision was reversed in 186 BC by his widow Grand Empress Dowager Lü Zhi (d. 180 BC), who abolished private minting. In 182 BC, Lü Zhi issued a bronze coin that was much lighter in weight than previous coins. This caused widespread inflation that was not reduced until 175 BC when Emperor Wen allowed private minters to manufacture coins that were precisely 2.6 g (0.09 oz) in weight.

In 144 BC Emperor Jing abolished private minting in favor of central-government and commandery-level minting; he also introduced a new coin. Emperor Wu introduced another in 120 BC, but a year later he abandoned the "ban liangs" entirely in favor of the "wuzhu" (五銖) coin, weighing 3.2 g (0.11 oz). The "wuzhu" became China's standard coin until the Tang dynasty (618–907 AD). Its use was interrupted briefly by several new currencies introduced during Wang Mang's regime until it was reinstated in 40 AD by Emperor Guangwu.

Since commandery-issued coins were often of inferior quality and lighter weight, the central government closed commandery mints and monopolized the issue of coinage in 113 BC. This Central government issuance of coinage was overseen by the Superintendent of Waterways and Parks, this duty being transferred to the Minister of Finance during Eastern Han.

Aside from the landowner's land tax paid in a portion of their crop yield, the poll tax and property taxes were paid in coin cash. The annual poll tax rate for adult men and women was 120 coins and 20 coins for minors. Merchants were required to pay a higher rate of 240 coins. The poll tax stimulated a money economy that necessitated the minting of over 28,000,000,000 coins from 118 BC to 5 AD, an average of 220,000,000 coins a year.

The widespread circulation of coin cash allowed successful merchants to invest money in land, empowering the very social class the government attempted to suppress through heavy commercial and property taxes. Emperor Wu even enacted laws which banned registered merchants from owning land, yet powerful merchants were able to avoid registration and own large tracts of land.

The small landowner-cultivators formed the majority of the Han tax base; this revenue was threatened during the latter half of Eastern Han when many peasants fell into debt and were forced to work as farming tenants for wealthy landlords. The Han government enacted reforms in order to keep small landowner-cultivators out of debt and on their own farms. These reforms included reducing taxes, temporary remissions of taxes, granting loans and providing landless peasants temporary lodging and work in agricultural colonies until they could recover from their debts.

In 168 BC, the land tax rate was reduced from one-fifteenth of a farming household's crop yield to one-thirtieth, and later to a one-hundredth of a crop yield for the last decades of the dynasty. The consequent loss of government revenue was compensated for by increasing property taxes.

The labor tax took the form of conscripted labor for one month per year, which was imposed upon male commoners aged fifteen to fifty-six. This could be avoided in Eastern Han with a commutable tax, since hired labor became more popular.

In the early Western Han, a wealthy salt or iron industrialist, whether a semi-autonomous king or wealthy merchant, could boast funds that rivaled the imperial treasury and amass a peasant workforce of over a thousand. This kept many peasants away from their farms and denied the government a significant portion of its land tax revenue. To eliminate the influence of such private entrepreneurs, Emperor Wu nationalized the salt and iron industries in 117 BC and allowed many of the former industrialists to become officials administering the state monopolies. By Eastern Han times, the central government monopolies were repealed in favor of production by commandery and county administrations, as well as private businessmen.

Liquor was another profitable private industry nationalized by the central government in 98 BC. However, this was repealed in 81 BC and a property tax rate of two coins for every 0.2 L (0.05 gallons) was levied for those who traded it privately. By 110 BC Emperor Wu also interfered with the profitable trade in grain when he eliminated speculation by selling government-stored grain at a lower price than demanded by merchants. Apart from Emperor Ming's creation of a short-lived Office for Price Adjustment and Stabilization, which was abolished in 68 AD, central-government price control regulations were largely absent during the Eastern Han.

The Han dynasty was a unique period in the development of premodern Chinese science and technology, comparable to the level of scientific and technological growth during the Song dynasty (960–1279).

In the 1st millennium BC, typical ancient Chinese writing materials were bronzewares, animal bones, and bamboo slips or wooden boards. By the beginning of the Han dynasty, the chief writing materials were clay tablets, silk cloth, hemp's paper, and rolled scrolls made from bamboo strips sewn together with hempen string; these were passed through drilled holes and secured with clay stamps.

The oldest known Chinese piece of hard, hempen wrapping paper dates to the 2nd century BC.The standard papermaking process was invented by Cai Lun (AD 50–121) in 105. The oldest known surviving piece of paper with writing on it was found in the ruins of a Han watchtower that had been abandoned in AD 110, in Inner Mongolia.

Evidence suggests that blast furnaces, that convert raw iron ore into pig iron, which can be remelted in a cupola furnace to produce cast iron by means of a cold blast and hot blast, were operational in China by the late Spring and Autumn period (722–481 BC). The bloomery was nonexistent in ancient China; however, the Han-era Chinese produced wrought iron by injecting excess oxygen into a furnace and causing decarburization. Cast iron and pig iron could be converted into wrought iron and steel using a fining process.

The Han dynasty Chinese used bronze and iron to make a range of weapons, culinary tools, carpenters' tools and domestic wares. A significant product of these improved iron-smelting techniques was the manufacture of new agricultural tools. The three-legged iron seed drill, invented by the 2nd century BC, enabled farmers to carefully plant crops in rows instead of casting seeds out by hand. The heavy moldboard iron plow, also invented during the Han dynasty, required only one man to control it, two oxen to pull it. It had three plowshares, a seed box for the drills, a tool which turned down the soil and could sow roughly 45,730 m (11.3 acres) of land in a single day.

To protect crops from wind and drought, the grain intendant Zhao Guo (趙過) created the alternating fields system ("daitianfa" 代田法) during Emperor Wu's reign. This system switched the positions of furrows and ridges between growing seasons. Once experiments with this system yielded successful results, the government officially sponsored it and encouraged peasants to use it. Han farmers also used the pit field system ("aotian" 凹田) for growing crops, which involved heavily fertilized pits that did not require plows or oxen and could be placed on sloping terrain. In southern and small parts of central Han-era China, paddy fields were chiefly used to grow rice, while farmers along the Huai River used transplantation methods of rice production.

Timber was the chief building material during the Han dynasty; it was used to build palace halls, multi-story residential towers and halls and single-story houses. Because wood decays rapidly, the only remaining evidence of Han wooden architecture is a collection of scattered ceramic roof tiles. The oldest surviving wooden halls in China date to the Tang dynasty (AD 618–907). Architectural historian Robert L. Thorp points out the scarcity of Han-era archaeological remains, and claims that often unreliable Han-era literary and artistic sources are used by historians for clues about lost Han architecture.

Though Han wooden structures decayed, some Han-dynasty ruins made of brick, stone, and rammed earth remain intact. This includes stone pillar-gates, brick tomb chambers, rammed-earth city walls, rammed-earth and brick beacon towers, rammed-earth sections of the Great Wall, rammed-earth platforms where elevated halls once stood, and two rammed-earth castles in Gansu. The ruins of rammed-earth walls that once surrounded the capitals Chang'an and Luoyang still stand, along with their drainage systems of brick arches, ditches, and ceramic water pipes. Monumental stone pillar-gates, twenty-nine of which survive from the Han period, formed entrances of walled enclosures at shrine and tomb sites. These pillars feature artistic imitations of wooden and ceramic building components such as roof tiles, eaves, and balustrades.

The courtyard house is the most common type of home portrayed in Han artwork. Ceramic architectural models of buildings, like houses and towers, were found in Han tombs, perhaps to provide lodging for the dead in the afterlife. These provide valuable clues about lost wooden architecture. The artistic designs found on ceramic roof tiles of tower models are in some cases exact matches to Han roof tiles found at archaeological sites.

Over ten Han-era underground tombs have been found, many of them featuring archways, vaulted chambers, and domed roofs. Underground vaults and domes did not require buttress supports since they were held in place by earthen pits. The use of brick vaults and domes in aboveground Han structures is unknown.

From Han literary sources, it is known that wooden-trestle beam bridges, arch bridges, simple suspension bridges, and floating pontoon bridges existed in Han China. However, there are only two known references to arch bridges in Han literature, and only a single Han relief sculpture in Sichuan depicts an arch bridge.

Underground mine shafts, some reaching depths over, were created for the extraction of metal ores. Borehole drilling and derricks were used to lift brine to iron pans where it was distilled into salt. The distillation furnaces were heated by natural gas funneled to the surface through bamboo pipelines. Dangerous amounts of additional gas were siphoned off via carburetor chambers and exhaust pipes.

Han-era mechanical engineering comes largely from the choice observational writings of sometimes-disinterested Confucian scholars who generally considered scientific and engineering endeavors to be far beneath them. Professional artisan-engineers ("jiang" 匠) did not leave behind detailed records of their work. Han scholars, who often had little or no expertise in mechanical engineering, sometimes provided insufficient information on the various technologies they described. Nevertheless, some Han literary sources provide crucial information. For example, in 15 BC the philosopher and writer Yang Xiong described the invention of the belt drive for a quilling machine, which was of great importance to early textile manufacturing. The inventions of mechanical engineer and craftsman Ding Huan (丁緩) are mentioned in the "Miscellaneous Notes on the Western Capital". Around AD 180, Ding created a manually operated rotary fan used for air conditioning within palace buildings. Ding also used gimbals as pivotal supports for one of his incense burners and invented the world's first known zoetrope lamp.

Modern archaeology has led to the discovery of Han artwork portraying inventions which were otherwise absent in Han literary sources. As observed in Han miniature tomb models, but not in literary sources, the crank handle was used to operate the fans of winnowing machines that separated grain from chaff. The odometer cart, invented during Han, measured journey lengths, using mechanical figures banging drums and gongs to indicate each distance traveled. This invention is depicted in Han artwork by the 2nd century, yet detailed written descriptions were not offered until the 3rd century. Modern archaeologists have also unearthed specimens of devices used during the Han dynasty, for example a pair of sliding metal calipers used by craftsmen for making minute measurements. These calipers contain inscriptions of the exact day and year they were manufactured. These tools are not mentioned in any Han literary sources.

The waterwheel appeared in Chinese records during the Han. As mentioned by Huan Tan about AD 20, they were used to turn gears that lifted iron trip hammers, and were used in pounding, threshing and polishing grain. However, there is no sufficient evidence for the watermill in China until about the 5th century. The Nanyang Commandery Administrator and mechanical engineer Du Shi (d. 38 AD) created a waterwheel-powered reciprocator that worked the bellows for the smelting of iron. Waterwheels were also used to power chain pumps that lifted water to raised irrigation ditches. The chain pump was first mentioned in China by the philosopher Wang Chong in his 1st-century "Balanced Discourse".

The armillary sphere, a three-dimensional representation of the movements in the celestial sphere, was invented in Han China by the 1st century BC. Using a water clock, waterwheel and a series of gears, the Court Astronomer Zhang Heng (AD 78–139) was able to mechanically rotate his metal-ringed armillary sphere. To address the problem of slowed timekeeping in the pressure head of the inflow water clock, Zhang was the first in China to install an additional tank between the reservoir and inflow vessel. Zhang also invented a device he termed an "earthquake weathervane" ("houfeng didong yi" 候風地動儀), which the British scientist and historian Joseph Needham described as "the ancestor of all seismographs". This device was able to detect the exact cardinal or ordinal direction of earthquakes from hundreds of kilometers away. It employed an inverted pendulum that, when disturbed by ground tremors, would trigger a set of gears that dropped a metal ball from one of eight dragon mouths (representing all eight directions) into a metal toad's mouth. The account of this device in the "Book of the Later Han" describes how, on one occasion, one of the metal balls was triggered without any of the observers feeling a disturbance. Several days later, a messenger arrived bearing news that an earthquake had struck in Longxi Commandery (in modern Gansu Province), the direction the device had indicated, which forced the officials at court to admit the efficacy of Zhang's device.

Three Han mathematical treatises still exist. These are the "Book on Numbers and Computation", the "Arithmetical Classic of the Gnomon and the Circular Paths of Heaven" and the "Nine Chapters on the Mathematical Art". Han-era mathematical achievements include solving problems with right-angle triangles, square roots, cube roots, and matrix methods, finding more accurate approximations for pi, providing mathematical proof of the Pythagorean theorem, use of the decimal fraction, Gaussian elimination to solve linear equations, and continued fractions to find the roots of equations.

One of the Han's greatest mathematical advancements was the world's first use of negative numbers. Negative numbers first appeared in the "Nine Chapters on the Mathematical Art" as black counting rods, where positive numbers were represented by red counting rods. Negative numbers were also used by the Greek mathematician Diophantus around AD 275, and in the 7th-century Bakhshali manuscript of Gandhara, South Asia, but were not widely accepted in Europe until the 16th century.
The Han applied mathematics to various diverse disciplines. In musical tuning, Jing Fang (78–37 BC) realized that 53 perfect fifths was approximate to 31 octaves while creating a musical scale of 60 tones, calculating the difference at ⁄ (the same value of 53 equal temperament discovered by the German mathematician Nicholas Mercator [1620–1687], i.e. 3/2).

Mathematics were essential in drafting the astronomical calendar, a lunisolar calendar that used the Sun and Moon as time-markers throughout the year. Use of the ancient Sifen calendar (古四分曆), which measured the tropical year at 365⁄ days, was replaced in 104 BC with the Taichu calendar (太初曆) that measured the tropical year at 365⁄ days and the lunar month at 29⁄ days. However, Emperor Zhang later reinstated the Sifen calendar.

Han Chinese astronomers made star catalogues and detailed records of comets that appeared in the night sky, including recording the 12 BC appearance of the comet now known as Halley's Comet.

Han dynasty astronomers adopted a geocentric model of the universe, theorizing that it was shaped like a sphere surrounding the earth in the center. They assumed that the Sun, Moon, and planets were spherical and not disc-shaped. They also thought that the illumination of the Moon and planets was caused by sunlight, that lunar eclipses occurred when the Earth obstructed sunlight falling onto the Moon, and that a solar eclipse occurred when the Moon obstructed sunlight from reaching the Earth. Although others disagreed with his model, Wang Chong accurately described the water cycle of the evaporation of water into clouds.

Evidence found in Chinese literature, and archaeological evidence, show that cartography existed in China before the Han. Some of the earliest Han maps discovered were ink-penned silk maps found amongst the Mawangdui Silk Texts in a 2nd-century-BC tomb. The general Ma Yuan created the world's first known raised-relief map from rice in the 1st century. This date could be revised if the tomb of Emperor Qin Shi Huang is excavated and the account in the "Records of the Grand Historian" concerning a model map of the empire is proven to be true.

Although the use of the graduated scale and grid reference for maps was not thoroughly described until the published work of Pei Xiu (AD 224–271, there is evidence that in the early 2nd century, cartographer Zhang Heng was the first to use scales and grids for maps.

Han dynasty Chinese sailed in a variety of ships differing from those of previous eras, such as the tower ship. The "junk" design was developed and realized during the Han era. Junk ships featured a square-ended bow and stern, a flat-bottomed hull or carvel-shaped hull with no keel or sternpost, and solid transverse bulkheads in the place of structural ribs found in Western vessels. Moreover, Han ships were the first in the world to be steered using a rudder at the stern, in contrast to the simpler steering oar used for riverine transport, allowing them to sail on the high seas.

Although ox-carts and chariots were previously used in China, the wheelbarrow was first used in Han China in the 1st century BC. Han artwork of horse-drawn chariots shows that the Warring-States-Era heavy wooden yoke placed around a horse's chest was replaced by the softer "breast strap". Later, during the Northern Wei (386–534), the fully developed horse collar was invented.

Han-era medical physicians believed that the human body was subject to the same forces of nature that governed the greater universe, namely the cosmological cycles of yin and yang and the five phases. Each organ of the body was associated with a particular phase. Illness was viewed as a sign that "qi" or "vital energy" channels leading to a certain organ had been disrupted. Thus, Han-era physicians prescribed medicine that was believed to counteract this imbalance. For example, since the wood phase was believed to promote the fire phase, medicinal ingredients associated with the wood phase could be used to heal an organ associated with the fire phase. Besides dieting, Han physicians also prescribed moxibustion, acupuncture, and calisthenics as methods of maintaining one's health. When surgery was performed by the Chinese physician Hua Tuo (d. AD 208), he used anesthesia to numb his patients' pain and prescribed a rubbing ointment that allegedly sped the process of healing surgical wounds. Whereas the physician Zhang Zhongjing (c. AD 150–c. 219) is known to have written the "Shanghan lun" ("Dissertation on Typhoid Fever"), it is thought that both he and Hua Tuo collaborated in compiling the "Shennong Ben Cao Jing" medical text.

The cultural affinity of the Xiongnu was with the peoples of southern Siberia and Central Asia; with the Chinese they exchanged arrows rather than culture: the Xiongnu shot with hand bows, while Chinese employed crossbows, although the Chinese had developed the crossbow from the traditional hand bows. Lev Gumilev elaborates the roots of the Chinese cultural influence found in the Noin-Ula cemetery. The Chinese culture was spread not only by material objects, but also by population admixture. There were populations of Xiongnu that have live under the Han rule as military allies. The Chinese migrated continuously to the steppes, the first big wave arriving in the 3rd century BC during the Tsin dynasty (Pin. "Qin"), when captured Chinese became subjects of the Chanuys, a process repeated during the following centuries. The numerous Han people who deserted and entered Chanuy service (for example, Vey Lüy, Li Lin) also taught the Xiongnu the subtlety of diplomacy and martial arts. Populations of the Xiongnu people also lived under Han rule, mostly serving as military allies under Han command. The capture of populations of Xiongnu by the Han forces in a series of Han versus Hun wars also contributed to additional ethnic integration of the north-central Asian neighbors.

Noin-Ula burial site

The Noin-Ula burial site (, Noyon uulyn bulsh) consist of more than 200 large burial mounds, approximately square in plan, some 2 m in height, covering timber burial chambers. They are located by the Selenga River in the hills of northern Mongolia north of Ulan Bator in Batsumber sum of Tov Province. They were excavated in 1924–1925 by Pyotr Kozlov, who found them to be the tombs of the aristocracy of the Xiongnu; one is an exceptionally rich burial of a historically known ruler of the Xiongnu, Uchjulü-Jodi-Chanuy, who died in 13 CE. Most of the objects from Noin-Ula are now in the Hermitage Museum, while some artifacts unearthed later by Mongolian archaeologists are on display in the National Museum of Mongolian History, Ulan Bator. Two kurgans contained lacquer cups, inscribed with Chinese characters believed to be the names of Chinese craftsmen, and dated September 5 year of Tsian-ping era, i.e. 2nd year BCE.

As with some finds of the Pazyryk culture, the Noin Ula graves had been flooded and subsequently frozen, thus preserving the organic material to a remarkable degree. The tombs were opened in antiquity and the bodies were removed. This corroborates the Han chronicles which state the leaders of one of the nomad tribes, oppressed by the Xiongnu at the height of their empire, took an unprecedented step 100 years after the decline of the Xiongnu. Wishing to unite their subjects, and driven by a desire for revenge, the new nomadic leaders desecrated the Chanuys' royal tombs. All the burials were unsealed, and the remains of the Chanuys were removed, together with some of their clothing, weaponry and symbols of authority. However, the robbers left Xiongnu weaponry, home utensils, and art objects, and Chinese artifacts of bronze, nephrite, lacquered wood and textiles. Many artifacts show origins along the Great Silk Road; some imported objects and fragments of fabrics are recognized as Greek. The fabric, color, weaving methods and embroidery of the cloth were similar to the fabric produced in the Greek colonies on the Black Sea coast for the Scythians.

Some tombs include horse burials and one tomb had especially lavish furnishings. The coffin was apparently made in China, and the interred person had many of his possessions buried with him. His horse trappings were elaborately decorated and his leather-covered saddle was threaded with black and red wool clipped to resemble velvet. Magnificent textiles included a woven wool rug lined with thin leather with purple, brown, and white felt appliqué work, and textiles of Greco-Bactrian, Parthian and Anatolian origin.

Kurgan No 6 was the tomb of Uchjulü-Jodi-Chanuy ("Uchilonoti", "Ulunoti", 烏珠留若提 "Wu-Zhou-Liu-Ju-Di", reigned 8 BCE–13 CE), who is mentioned in the Chinese annals. He is famous for freeing his people from the Chinese protectorate that lasted 56 years, from 47 BCE to 9 CE. Uchjulü-Jodi-Chanuy was buried in 13 CE, a date established from the inscription on a cup given to him by the Chinese Emperor during a reception in the Shanlin park near Chang'an in 1 BCE.

During the life of Uchjulü-Jodi-Chanuy, the Chinese dominated the steppe politically. For a generous reward by the Chinese, he changed his personal name Nanchjiyasy to Chji. On ascending to the throne, he confirmed the standing agreement between the Han Chinese and the Xiongnu: "Henceforth the Han and Hun will be one House, from generation to generation they will not deceive each other, nor attack each other. If a larceny happens, they will mutually inform and execute and compensate, in the event of raids by enemies they will help each other with troops. He of them who is first to breach the agreement, he will be penalized by the Sky, and his posterity from generation to generation would suffer under I this oath".

Despite this agreement, during Uchjulü-Jodi-Chanuy's reign relations with China went from cordial to antagonistic when a usurper Wang Mang came to power, which ended the Western Han Dynasty, and establishing the short-lived Xin Dynasty. Assembling a 300,000-strong army, Wang Mang began military actions, but his attempts ended in futility. Uchjulü-Jodi-Chanuy died in AD 13, before the end of the war. His successor was Uley-Jodi-Chanuy of the Süybu clan.

The most dramatic objects of Uchjulü-Jodi-Chanuy's funeral inventory are the textiles, of local, Chinese and Bactrian origin. The art objects show that Xiongnu craftsmen used the Scythian "animal" style.

A surviving portrait shows a low nose bridge, eyes with epicanthic fold, long wavy hair, divided in the middle, and a braid tied visibly and falling from the tip of the head over the right ear. Such braids were found in other kurgan tombs in the Noin Ula cemetery, they were braided from horsehair, and kept in special cases. The braid was a part of a formal hairstyle, and the braid resembles the death-masks of the Tashtyk. This appearance of the masks demonstrate that in the 1st century AD a far-eastern appearance was perceived by the Huns as more attractive than one of western type, resembling modern Telengits who consider large eyes and high nose to be ugly. From these observations, L.N. Gumilev concluded that among the Huns of the 1st century BC, a far-eastern ideal of beauty overcame the traditional western model, which continued in the art of the Scythian "animal" style.

Many immigrants lived in the Xiongnu pasturelands, but at first they did not mix with the Xiongnu. To be a Xiongnu, one had to be a member of a clan, born of Xiongnu parents. The newcomers were well off, but were outsiders, and could marry only among themselves, not the Xiongnu. Only later did they intermix, increase in numbers, even created a state that existed from 318 to 350 AD.

The Xiongnu culture can be differentiated into local, Scytho-Sarmatian, and Chinese. Most everyday objects were produced locally, showing the stability of the nomadic culture; Chinese masters made small handmade objects and ornaments, while objects with ideological connotations originated from the Scythian, Sarmatian and Dinlin S. Siberian cultures.

Despite the aforementioned excavated Noin-Ula portrait indicating Mongoloid lineage of the Xiongnu, Euro-centric observers of Xiongnu culture and history try to place the Xiongnu people in a non-Mongoloid or non-Asian ancestry or descendancy. Among the most important artifacts from Noin-Ula are embroidered portrait images. These shed light on the ethnicity of the Xiongnu, albeit controversially. It has been claimed that the portraits depict Greco-Bactrians, or are Greek depictions of Scythian soldiers from the Black Sea. Such suggestions are far-fetched. There are several historical sources confirming the appearance of the Xiongnu. In 350 AD, for example, power in the South Xiongnu state of Chjao (Pin. "Zhao") was seized by a usurper, a Chinese named Shi Min, who ordered all the Xiongnu in the state exterminated; in the slaughter "many Chinese with prominent noses" died, suggesting the Xiongnu had "prominent noses" compared to those of the Chinese. In the famous Chinese bas-relief "Fight on the bridge" the mounted Xiongnu are shown with big noses. A skull analysis of Xiongnu burials made by G.F. Debets found a distinct Paleo-Siberian type of Asian facial appearance with "not a flat, but with not strongly protruding nose", somewhat similar to some North American Indians. This type is represented on the embroidery from Noin-Ula. What to the rest of the Chinese looked like a high nose, to the Europeans looked like a flat nose.

The portraits are not made in the Chinese manner, and are the handiwork of a Central Asian or Scythian artist, or perhaps of a Bactrian or Parthian master in the capital of the Chanüys (who had active diplomatic relations with these Central Asian states).

The hairstyle on one portrait shows long hair bound with a wide ribbon. This is identical with the coiffure of the Türkic Ashina clan, who were originally from the Hesi province. The Ashina belonged to the last Xiongnu princedom destroyed by Xianbei-Toba by AD 439. From Gansu, the Ashina retreated to the Altai, taking with them a number of distinctive ethnographic traits.

Chinese sources indicate that the Xiongnu did not have an ideographic form of writing like Chinese, but in the 2nd century BC, a renegade Chinese dignitary Yue "taught the Shanyu to write official letters to the Chinese court on a wooden tablet 31 cm long, and to use a seal and large-sized folder." The same sources tell that when the Xiongnu noted down something or transmitted a message, they made cuts on a piece of wood ('ke-mu'), and they also mention a "Hu script". At Noin-Ula and other Xiongnu burial sites in Mongolia and the region north of Lake Baikal, among the objects were discovered over 20 carved characters. Most of these characters are either identical or very similar to letters of the Old Turkic alphabet of the Early Middle Ages found on the Eurasian steppes. From this, some specialists conclude that the Xiongnu used a script similar to the ancient "Eurasian runiform", and that this alphabet was a basis for later Turkic writing.

The Noin-Ula burials were intensively studied, but because the cemetery was desecrated in antiquity and bodies removed, no craniological, odontological, or genetic studies could be conducted. One exception is the odontological study of preserved enamel caps of seven permanent teeth belonging to a young woman. The study describes highly diagnostic traits with a very rare combination found in certain ancient and modern populations of the Caspian–Aral region and in the northern Indus–Ganges interfluve. A Parthian woolen cloth in the grave indicates that the woman was of northwestern Indian origin associated with the Parthian culture. The finds suggest that at the beginning of the Common Era, peoples of Parthian origin were incorporated within Xiongnu society. Parthians belonged to the tribal union called in ancient Greek Dahae, also known as Tokhars and in Chinese as Yuezhi.original colors of a carpet from Noyon uul]. Moscow-Leningrad, 1937.
