Who was the first leader of West Germany?

Konrad Adenauer (1876–1967) was the dominant leader in West Germany. He was the first chancellor (top official) of the FRG, 1949–63, and until his death was the founder and leader of the Christian Democratic Union (CDU), a coalition of conservatives, ordoliberals, and adherents of Protestant and Catholic social teaching that dominated West Germany politics for most of its history. During his chancellorship, the West Germany economy grew quickly, and West Germany established friendly relations with France, participated in the emerging European Union, established the country's armed forces (the "Bundeswehr"), and became a pillar of NATO as well as firm ally of the United States. Adenauer's government also commenced the long process of reconciliation with the Jews and Israel after the Holocaust.

History of Germany

The concept of Germany as a distinct region in central Europe can be traced to Roman commander Julius Caesar, who referred to the unconquered area east of the Rhine as "Germania", thus distinguishing it from Gaul (France), which he had conquered. The victory of the Germanic tribes in the Battle of the Teutoburg Forest (AD 9) prevented annexation by the Roman Empire, although the Roman provinces of Germania Superior and Germania Inferior were established along the Rhine. Following the Fall of the Western Roman Empire, the Franks conquered the other West Germanic tribes. When the Frankish Empire was divided among Charles the Great's heirs in 843, the eastern part became East Francia. In 962, Otto I became the first Holy Roman Emperor of the Holy Roman Empire, the medieval German state.

In the Late Middle Ages, the regional dukes, princes and bishops gained power at the expense of the emperors. Martin Luther led the Protestant Reformation against the Catholic Church after 1517, as the northern states became Protestant, while the southern states remained Catholic. The two parts of the Holy Roman Empire clashed in the Thirty Years' War (1618–1648), which was ruinous to the twenty million civilians living in both parts. The Thirty Years' War brought tremendous destruction to Germany; more than 1/4 of the population and 1/2 of the male population in the German states were killed by the catastrophic war. 1648 marked the effective end of the Holy Roman Empire and the beginning of the modern nation-state system, with Germany divided into numerous independent states, such as Prussia, Bavaria, Saxony, Austria and other states, which also controlled land outside of the area considered as "Germany".

After the French Revolution and the Napoleonic Wars from 1803–1815, feudalism fell away and liberalism and nationalism clashed with reaction. The German revolutions of 1848–49 failed. The Industrial Revolution modernized the German economy, led to the rapid growth of cities and to the emergence of the socialist movement in Germany. Prussia, with its capital Berlin, grew in power. German universities became world-class centers for science and humanities, while music and art flourished. The unification of Germany (excluding Austria and the German-speaking areas of Switzerland) was achieved under the leadership of the Chancellor Otto von Bismarck with the formation of the German Empire in 1871 which solved the "Kleindeutsche Lösung", the small Germany solution (Germany without Austria), or "Großdeutsche Lösung", the greater Germany solution (Germany with Austria), the former prevailing. The new "Reichstag", an elected parliament, had only a limited role in the imperial government. Germany joined the other powers in colonial expansion in Africa and the Pacific.

Germany was the dominant power on the continent. By 1900, its rapidly expanding industrial economy passed Britain's, allowing a naval race. Germany led the Central Powers in World War I (1914–1918) against France, Great Britain, Russia and (by 1917) the United States. Defeated and partly occupied, Germany was forced to pay war reparations by the Treaty of Versailles and was stripped of its colonies as well as areas given to re-established Poland and Alsace-Lorraine. The German Revolution of 1918–19 deposed the emperor and the various kings and princes, leading to the establishment of the Weimar Republic, an unstable parliamentary democracy.

In the early 1930s, the worldwide Great Depression hit Germany hard, as unemployment soared and people lost confidence in the government. In January 1933, Adolf Hitler was appointed Chancellor of Germany. The Nazi Party then began to eliminate all political opposition and consolidate its power. Hitler quickly established a totalitarian regime. Beginning in the late 1930s, Nazi Germany made increasingly aggressive territorial demands, threatening war if they were not met. First came the remilitarization of the Rhineland in 1936, the annexing of Austria in the "Anschluss" and parts of Czechoslovakia with the Munich Agreement in 1938 (although in 1939 Hitler annexed further territory of Czechoslovakia). On 1 September 1939, Germany initiated World War II in Europe with the invasion of Poland. After forming a pact with the Soviet Union in 1939, Hitler and Stalin divided Eastern Europe. After a "Phoney War" in spring 1940, the Germans swept Denmark and Norway, the Low Countries and France, giving Germany control of nearly all of Western Europe. Hitler invaded the Soviet Union in June 1941.

Racism, especially antisemitism, was a central feature of the Nazi regime. In Germany, but predominantly in the German-occupied areas, the systematic genocide program known as The Holocaust killed six million Jews, as well as five million others including German dissidents, gipsies, disabled people, Poles, Romanies, Soviets (Russian and non-Russian), and others. In 1942, the German invasion of the Soviet Union faltered, and after the United States had entered the war, Britain became the base for massive Anglo-American bombings of German cities. Germany fought the war on multiple fronts through 1942–1944, however following the Allied invasion of Normandy (June 1944), the German Army was pushed back on all fronts until the final collapse in May 1945.

Under occupation by the Allies, German territories were split up, Austria was again made a separate country, denazification took place, and the Cold War resulted in the division of the country into democratic West Germany and communist East Germany. Millions of ethnic Germans were deported or fled from Communist areas into West Germany, which experienced rapid economic expansion, and became the dominant economy in Western Europe. West Germany was rearmed in the 1950s under the auspices of NATO, but without access to nuclear weapons. The Franco-German friendship became the basis for the political integration of Western Europe in the European Union. In 1989, the Berlin Wall was destroyed, the Soviet Union collapsed and East Germany was reunited with West Germany in 1990. In 1998–1999, Germany was one of the founding countries of the eurozone. Germany remains one of the economic powerhouses of Europe, contributing about one quarter of the eurozone's annual gross domestic product. In the early 2010s, Germany played a critical role in trying to resolve the escalating euro crisis, especially with regard to Greece and other Southern European nations. In the middle of the decade, the country faced the European migrant crisis as the main receiver of asylum seekers from Syria and other troubled regions.

The discovery of the Mauer 1 mandible in 1907 shows that ancient humans were present in Germany at least 600,000 years ago. The oldest complete hunting weapons ever found anywhere in the world were discovered in a coal mine in Schoningen, Germany in 1995 where three 380,000-year-old wooden javelins 6–7.5 feet (1.8–2.3 meter) long were unearthed. The Neander valley in Germany was the location where the first ever non-modern human fossil was discovered and recognised in 1856; the new species of human was named Neanderthal man. The Neanderthal 1 fossils are now known to be 40,000 years old. At a similar age, evidence of modern humans has been found in caves in the Swabian Jura near Ulm. The finds include 42,000-year-old bird bone and mammoth ivory flutes which are the oldest musical instruments ever found, the 40,000-year-old Ice Age Löwenmensch figurine which is the oldest uncontested figurative art ever discovered, and the 35,000-year-old Venus of Hohle Fels which is the oldest uncontested human figurative art ever discovered.

The ethnogenesis of the Germanic tribes is assumed to have occurred during the Nordic Bronze Age, or at the latest during the Pre-Roman Iron Age. From their homes in southern Scandinavia and northern Germany the tribes began expanding south, east and west in the 1st century BC, coming into contact with the Celtic tribes of Gaul, as well as with Iranian, Baltic, and Slavic cultures in Central/Eastern Europe.

Researchers know few details of early Germanic activity, except through the tribes' recorded interactions with the Roman Empire, through etymological research and from archaeological finds. During the late Roman Republic, Julius Caesar built the first known bridges across the Rhine as part of his campaign in Gaul in the mid-1st century BC. The Germanic Suebi ruler Ariovistus fought the Romans under Julius Caesar in 58 BC at the Battle of Vosges in what is now Alsace but was driven back across the Rhine.

In the first years of the 1st century AD Roman legions conducted a long campaign in Germania, the area north of the Upper Danube and east of the Rhine, in an attempt to expand the Empire's frontiers and to shorten its frontier line. Rome subdued several Germanic tribes, such as the Cherusci. The tribes became familiar with Roman tactics of warfare while maintaining their tribal identity. In 9 AD a Cherusci chieftain known to the Romans as Arminius defeated a Roman army in the Battle of the Teutoburg Forest, a victory credited with stopping the Roman advance into Germanic territories. That part of the territory of modern Germany that lay east of the Rhine remained outside the Roman Empire. By AD 100, the time of Tacitus's "Germania", Germanic tribes had settled along the Roman frontier along the Rhine and the Danube (the "Limes Germanicus"), occupying most of the area of modern Germany; however, imperial Rome organised territory later included in the modern states of Austria, Baden-Württemberg, southern Bavaria, southern Hesse, Saarland and the Rhineland as Roman provinces (Noricum, Raetia, and Germania). The Roman provinces in western Germany, Germania Inferior (with the capital situated at Colonia Claudia Ara Agrippinensium, modern Cologne) and Germania Superior (with its capital at Mogontiacum, modern Mainz), were formally established in 85 AD, after a long period of military occupation beginning in the reign of the Roman emperor Augustus (27 BC – 14 AD).

The 3rd century saw the emergence of a number of large West Germanic tribes: the Alamanni, Franks, Bavarii, Chatti, Saxons, Frisii, Sicambri, and Thuringii. Around 260 the Germanic peoples broke through the "limes" and the Danube frontier into Roman-controlled lands.

Seven large German-speaking tribes – the Visigoths, Ostrogoths, Vandals, Burgundians, Lombards, Saxons and Franks – moved west and witnessed the decline of the Roman Empire and the transformation of the old Western Roman Empire.

Christianity was spread to western Germany during the Roman era, and Christian religious structures such as the Aula Palatina of Trier were built during the reign of Constantine I (r. (306–337 AD). At the end of the 4th century the Huns invaded the unoccupied part of present-day Germany and the Migration Period began. Hunnic hegemony over Germania lasted until the death of Attila's son Dengizich in 469.

Stem duchies (tribal duchies) in Germany originated as the areas of the Germanic tribes of a given region. The concept of such duchies survived especially in the areas which in the mid-9th century would become part of East Francia (for example: Bavaria, Swabia, Saxony, Franconia, Thuringia) rather than further west in Middle Francia (for example: Burgundy, Lorraine

In the 5th century, the "Völkerwanderung" (or Germanic migrations) brought a number of "barbarian" tribes into the failing Roman Empire. Tribes that became stem duchies were originally the Alamanni, the Thuringii, the Saxons, the Franks, the Burgundians, and the Rugii.
In contrast to later duchies, these entities did not have strictly delineated administrative boundaries, but approximated the area of settlement of major Germanic tribes. Over the next few centuries, some tribes warred, migrated, and merged. Eventually the Franks subjugated all these tribes in Germania. However, remnants of several stem duchies survive today as states or regions in modern Western Europe countries: German states such as Bavaria and Saxony, German regions like Swabia, and French "région"s such as of Burgundy/Franche-Comté and Lorraine.

In the east, successive rulers of the German lands founded a series of border counties or marches. To the north, these included Lusatia, the North March (which would become Brandenburg and the heart of the future Prussia), and the Billung March. In the south, the marches included Carniola, Styria, and the March of Austria that would become Austria.

After the fall of the Western Roman Empire in the 5th century, the Franks, like other post-Roman Western Europe, emerged as a tribal confederacy in the Rhine-Weser region referred to as "Austrasia," now Franconia. They absorbed much former Roman territory as they spread west into Gaul beginning in 250, unlike the Alamanni to their south in Swabia. By 500, the Frankish king Clovis I, of the Merovingian dynasty, had united the Frankish tribes and ruled all of Gaul, and was proclaimed king some time from 509 to 511. Clovis also, contrary to the tradition of Germanic rulers of the time, was baptized directly into Roman Catholicism and not Arianism, and his successors would work closely with papal missionaries, among them Saint Boniface. The faith of the Franks, the vast size of Francia, and the Franks' control of the passes through the Alps led to the alliance between the Merovingian realm, which by 750 now extended Gaul and north-western Germany to include Swabia, Burgundy (and western Switzerland by extension), with the Pope in Rome against the Lombards, who now posed the greatest threat to the Holy See. A Papal envoy was sent to Charles Martel, Mayor of the Palace, in 732 following his victory at the Battle of Tours, though this alliance would lapse with Charles' death and be renewed after the Frankish Civil War.

The Merovingian kings of the Germanic Franks conquered northern Gaul in 486 AD. Swabia became a duchy under the Frankish Empire in 496, following the Battle of Tolbiac; in 530 the Saxons and the Franks destroyed the Kingdom of Thuringia. In the 5th and 6th centuries the Merovingian kings conquered several other Germanic tribes and kingdoms. King Chlothar I (reigned 558–561) ruled the greater part of what is now Germany and made expeditions into Saxony, while the Southeast of modern Germany remained under the influence of the Ostrogoths. Saxons inhabited the area down to the Unstrut River.

The Merovingians placed the various regions of their Frankish Empire under the control of semi-autonomous dukes – Franks or local rulers. Frankish colonists were encouraged to move to the newly conquered territories. While allowed to preserve their own laws, the local Germanic tribes faced pressure to adopt non-Arian Christianity.

The territories which would later become parts of modern Germany came under the region of Austrasia (meaning "eastern land"), the northeastern portion of the Kingdom of the Merovingian Franks. As a whole, Austrasia comprised parts of present-day France, Germany, Belgium, Luxembourg and the Netherlands. After the death of the Frankish king Clovis I in 511, his four sons partitioned his kingdom including Austrasia. Authority over Austrasia passed back and forth from autonomy to royal subjugation, as successive Merovingian kings alternately united and subdivided the Frankish lands.

In 718 Charles Martel, the Frankish Mayor of the Palace, made war against Saxony because of its help for the Neustrians. His son Carloman started a new war against Saxony in 743, because the Saxons gave aid to Duke Odilo of Bavaria.

In 751 Pippin III, Mayor of the Palace under the Merovingian king, himself assumed the title of king and was anointed by the Church. Now the Frankish kings were set up as protectors of the pope, and Charles the Great (who ruled the Franks from 774 to 814) launched a decades-long military campaign against the Franks' heathen rivals, the Saxons and the Avars. The campaigns and insurrections of the Saxon Wars lasted from 772 to 804. The Franks eventually overwhelmed the Saxons and Avars, forcibly converted the people to Christianity, and annexed their lands to the Carolingian Empire.

After the death of Frankish king Pepin the Short in 768, his oldest son "Charlemagne" ("Charles the Great") consolidated his power over and expanded the Kingdom. In 773-74, Charlemagne ended 200 years of Royal Lombard rule with the Siege of Pavia, and installed himself as King of the Lombards and loyal Frankish nobles replaced the old Lombard elite following a rebellion in 776. The next 30 years of his reign were spent ruthlessly strengthening his power in Francia and conquering the territories of all west Germanic peoples, including the Saxons and the Baiuvarii (Bavarians). On Christmas Day, 800 AD, Charlemagne was crowned Emperor in Rome by Pope Leo III.

Fighting among Charlemagne's grandchildren caused the Carolingian empire to be partitioned into three parts in 843. The German region developed out of the East Frankish kingdom, East Francia. From 919 to 936, the Germanic peoples – Franks, Saxons, Swabians, and Bavarians – were united under Henry the Fowler, Duke of Saxony, who took the title of king. Imperial strongholds, called "Kaiserpfalzen", became economic and cultural centers, of which Aachen was the most famous.

In 936, Otto I was crowned as king at Aachen; his coronation as emperor by Pope John XII at Rome in 962 inaugurated what became later known as the Holy Roman Empire, which came to be identified with Germany. Otto strengthened the royal authority by re-asserting the old Carolingian rights over ecclesiastical appointments. Otto wrested from the nobles the powers of appointment of the bishops and abbots, who controlled large land holdings. Additionally, Otto revived the old Carolingian program of appointing missionaries in the border lands. Otto continued to support celibacy for the higher clergy, so ecclesiastical appointments never became hereditary. By granting land to the abbots and bishops he appointed, Otto actually made these bishops into "princes of the Empire" ("Reichsfürsten"); in this way, Otto was able to establish a national church. Outside threats to the kingdom were contained with the decisive defeat of the Hungarian Magyars at the Battle of Lechfeld in 955. The Slavs between the Elbe and the Oder rivers were also subjugated. Otto marched on Rome and drove John XII from the papal throne and for years controlled the election of the pope, setting a firm precedent for imperial control of the papacy for years to come.

During the reign of Conrad II's son, Henry III (1039 to 1056), the empire supported the Cluniac reforms of the Church, the Peace of God, prohibition of simony (the purchase of clerical offices), and required celibacy of priests. Imperial authority over the Pope reached its peak. In the Investiture Controversy which began between Henry IV and Pope Gregory VII over appointments to ecclesiastical offices, the emperor was compelled to submit to the Pope at Canossa in 1077, after having been excommunicated. In 1122 a temporary reconciliation was reached between Henry V and the Pope with the Concordat of Worms. The consequences of the investiture dispute were a weakening of the Ottonian church ("Reichskirche"), and a strengthening of the Imperial secular princes.

The time between 1096 and 1291 was the age of the crusades. Knightly religious orders were established, including the Knights Templar, the Knights of St John (Knights Hospitaller), and the Teutonic Order.

The term "sacrum imperium" (Holy Empire) was first used under Friedrich I, documented first in 1157, but the words "Sacrum Romanum Imperium", Holy Roman Empire, were only combined in July 1180 and would never consistently appear on official documents from 1254 onwards.

Long-distance trade in the Baltic intensified, as the major trading towns became drawn together in the Hanseatic League, under the leadership of Lübeck. The Hanseatic League was a business alliance of trading cities and their guilds that dominated trade along the coast of Northern Europe. Each of the Hanseatic cities had its own legal system and a degree of political autonomy. The chief cities were Cologne on the Rhine River, Hamburg and Bremen on the North Sea, and Lübeck on the Baltic. The League flourished from 1200 to 1500, and continued with lesser importance after that.

The German colonisation and the chartering of new towns and villages began into largely Slav-inhabited territories east of the Elbe, such as Bohemia, Silesia, Pomerania, and Livonia. Beginning in 1226, the Teutonic Knights began their conquest of Prussia. The native Baltic Prussians were conquered and Christianized by the Knights with much warfare, and numerous German towns were established along the eastern shore of the Baltic Sea.

Henry V (1086–1125), great-grandson of Conrad II, became Holy Roman Emperor in 1106 in the midst of a civil war. Hoping to gain complete control over the church inside the Empire, Henry V appointed Adalbert of Saarbrücken as the powerful archbishop of Mainz in 1111. Adalbert began to assert the powers of the Church against secular authorities, that is, the Emperor. This precipitated the "Crisis of 1111", part of the long-term Investiture Controversy. In 1137 the magnates turned back to the Hohenstaufen family for a candidate, Conrad III. Conrad III tried to divest Henry the Proud of his two duchies – Bavaria and Saxony – leading to war in southern Germany as the Empire divided into two factions. The first faction called themselves the "Welfs" or "Guelphs" after Henry the Proud's family, which was the ruling dynasty in Bavaria; the other faction was known as the "Waiblings." In this early period, the Welfs generally represented ecclesiastical independence under the papacy plus "particularism" (a strengthening of the local duchies against the central imperial authority). The Waiblings, on the other hand, stood for control of the Church by a strong central Imperial government.

Between 1152 and 1190, during the reign of Frederick I (Barbarossa), of the Hohenstaufen dynasty, an accommodation was reached with the rival Guelph party by the grant of the duchy of Bavaria to Henry the Lion, duke of Saxony. Austria became a separate duchy by virtue of the Privilegium Minus in 1156. Barbarossa tried to reassert his control over Italy. In 1177 a final reconciliation was reached between the emperor and the Pope in Venice.

In 1180, Henry the Lion was outlawed; Saxony was divided, and Bavaria was given to Otto of Wittelsbach. (Otto founded the Wittelsbach dynasty, which was to rule Bavaria until 1918.)

From 1184 to 1186, the Hohenstaufen empire under Frederick I Barbarossa reached its peak in the "Reichsfest" (imperial celebrations) held at Mainz and the marriage of his son Henry in Milan to the Norman princess Constance of Sicily. The power of the feudal lords was undermined by the appointment of "ministerials" (unfree servants of the Emperor) as officials. Chivalry and the court life flowered, leading to a development of German culture and literature (see Wolfram von Eschenbach).

Between 1212 and 1250, Frederick II established a modern, professionally administered state from his base in Sicily. He resumed the conquest of Italy, leading to further conflict with the Papacy. In the Empire, extensive sovereign powers were granted to ecclesiastical and secular princes, leading to the rise of independent territorial states. The struggle with the Pope sapped the Empire's strength, as Frederick II was excommunicated three times. After his death, the Hohenstaufen dynasty fell, followed by an interregnum during which there was no Emperor.

The failure of negotiations between Emperor Louis IV and the papacy led in 1338 to the declaration at Rhense by six electors to the effect that election by all or the majority of the electors automatically conferred the royal title and rule over the empire, without papal confirmation. As result, the monarch was no longer subject to papal approbation and became increasingly dependent on the favour of the electors. Between 1346 and 1378 Emperor Charles IV of Luxembourg, king of Bohemia, sought to restore the imperial authority. The Golden Bull of 1356 stipulated that in future the emperor was to be chosen by four secular electors and three spiritual electors. The secular electors were the King of Bohemia, the Count Palatine of the Rhine, the Duke of Saxony, and the Margrave of Brandenburg; the three spiritual electors were the Archbishops of Mainz, Trier, and Cologne.

Around 1350, Germany and almost the whole of Europe were ravaged by the Black Death. Jews were persecuted on religious and economic grounds; many fled to Poland. The Black Death is estimated to have killed 30–60 percent of Europe's population in the 14th century.

After the disasters of the 14th century – war, plague, and schism – early-modern European society gradually came into being as a result of economic, religious, and political changes. A money economy arose which provoked social discontent among knights and peasants. Gradually, a proto-capitalistic system evolved out of feudalism. The Fugger family gained prominence through commercial and financial activities and became financiers to both ecclesiastical and secular rulers. The knightly classes established their monopoly on arms and military skill. However, it was undermined by the introduction of mercenary armies and foot soldiers. Predatory activity by "robber knights" became common.

From 1438 the Habsburgs, who controlled most of the southeast of the Empire (more or less modern-day Austria and Slovenia, and Bohemia and Moravia after the death of King Louis II in 1526), maintained a constant grip on the position of the Holy Roman Emperor until 1806 (with the exception of the years between 1742 and 1745). This situation, however, gave rise to increased disunity among the Holy Roman Empire's territorial rulers and prevented sections of the country from coming together to form nations in the manner of France and England.

During his reign from 1493 to 1519, Maximilian I tried to reform the Empire. An Imperial supreme court ("Reichskammergericht") was established, imperial taxes were levied, and the power of the Imperial Diet ("Reichstag") was increased. The reforms, however, were frustrated by the continued territorial fragmentation of the Empire.

The German lands had a population of about 5 or 6 million. The great majority were farmers, typically in a state of serfdom under the control of nobles and monasteries. A few towns were starting to emerge. From 1100, new towns were founded around imperial strongholds, castles, bishops' palaces, and monasteries. The towns began to establish municipal rights and liberties (see German town law). Several cities such as Cologne became Imperial Free Cities, which did not depend on princes or bishops, but were immediately subject to the Emperor. The towns were ruled by patricians: merchants carrying on long-distance trade. Craftsmen formed guilds, governed by strict rules, which sought to obtain control of the towns; a few were open to women. Society was divided into sharply demarcated classes: the clergy, physicians, merchants, various guilds of artisans, and peasants; full citizenship was not available to paupers. Political tensions arose from issues of taxation, public spending, regulation of business, and market supervision, as well as the limits of corporate autonomy.

Cologne's central location on the Rhine river placed it at the intersection of the major trade routes between east and west and was the basis of Cologne's growth. The economic structures of medieval and early modern Cologne were characterized by the city's status as a major harbor and transport hub upon the Rhine. It was the seat of the archbishops, who ruled the surrounding area and (from 1248 to 1880) built the great Cologne Cathedral, with sacred relics that made it a destination for many worshippers. By 1288 the city had secured its independence from the archbishop (who relocated to Bonn), and was ruled by its burghers.

From the early medieval period and continuing through to the 18th century, Germanic law assigned women to a subordinate and dependent position relative to men. Salic (Frankish) law, from which the laws of the German lands would be based, placed women at a disadvantage with regard to property and inheritance rights. Germanic widows required a male guardian to represent them in court. Unlike Anglo-Saxon law or the Visigothic Code, Salic law barred women from royal succession. Social status was based on military and biological roles, a reality demonstrated in rituals associated with newborns, when female infants were given a lesser value than male infants. The use of physical force against wives was condoned until the 18th century in Bavarian law.

Some women of means asserted their influence during the Middle Ages, typically in royal court or convent settings. Hildegard of Bingen, Gertrude the Great, Elisabeth of Bavaria (1478–1504), and Argula von Grumbach are among the women who pursued independent accomplishments in fields as diverse as medicine, music composition, religious writing, and government and military politics.

Benedictine abbess Hildegard von Bingen (1098–1179) wrote several influential theological, botanical, and medicinal texts, as well as letters, liturgical songs, poems, and arguably the oldest surviving morality play, while supervising brilliant miniature Illuminations. About 100 years later, Walther von der Vogelweide (c. 1170 – c. 1230) became the most celebrated of the Middle High German lyric poets.

Around 1439, Johannes Gutenberg of Mainz, used movable type printing and issued the Gutenberg Bible. He was the global inventor of the printing press, thereby starting the Printing Revolution. Cheap printed books and pamphlets played central roles for the spread of the Reformation and the Scientific Revolution.

Around the transition from the 15th to the 16th century, Albrecht Dürer from Nuremberg established his reputation across Europe as painter, printmaker, mathematician, engraver, and theorist when he was still in his twenties and secured his reputation as one of the most important figures of the Northern Renaissance.

The addition "Nationis Germanicæ" (of German Nation) to the emperor's title appeared first in the 15th century: in a 1486 law decreed by Frederick III and in 1512 in reference to the Imperial Diet in Cologne by Maximilian I. By then, the emperors had lost their influence in Italy and Burgundy. In 1525, the Heilbronn reform plan – the most advanced document of the German Peasants' War ("Deutscher Bauernkrieg") – referred to the "Reich" as "von Teutscher Nation" (of German nation).

In the early 16th century there was much discontent occasioned by abuses such as indulgences in the Catholic Church, and a general desire for reform.

In 1517 the Reformation began with the publication of Martin Luther's 95 Theses; he posted them in the town square and gave copies of them to German nobles, but it is debated whether he nailed them to the church door in Wittenberg as is commonly said. The list detailed 95 assertions Luther believed to show corruption and misguidance within the Catholic Church. One often cited example, though perhaps not Luther's chief concern, is a condemnation of the selling of indulgences; another prominent point within the 95 Theses is Luther's disagreement both with the way in which the higher clergy, especially the pope, used and abused power, and with the very idea of the pope.

In 1521 Luther was outlawed at the Diet of Worms. But the Reformation spread rapidly, helped by the Emperor Charles V's wars with France and the Turks. Hiding in the Wartburg Castle, Luther translated the Bible from Latin to German, establishing the basis of the German language. A curious fact is that Luther spoke a dialect which had minor importance in the German language of that time. After the publication of his Bible, his dialect suppressed the others and evolved into what is now the modern German.

In 1524 the German Peasants' War broke out in Swabia, Franconia and Thuringia against ruling princes and lords, following the preaching of Reformers. But the revolts, which were assisted by war-experienced noblemen like Götz von Berlichingen and Florian Geyer (in Franconia), and by the theologian Thomas Münzer (in Thuringia), were soon repressed by the territorial princes. As many as 100,000 German peasants were massacred during the revolt. With the protestation of the Lutheran princes at the Imperial Diet of Speyer (1529) and rejection of the Lutheran "Augsburg Confession" at Augsburg (1530), a separate Lutheran church emerged.

From 1545 the Counter-Reformation began in Germany. The main force was provided by the Jesuit order, founded by the Spaniard Ignatius of Loyola. Central and northeastern Germany were by this time almost wholly Protestant, whereas western and southern Germany remained predominantly Catholic. In 1547, Holy Roman Emperor Charles V defeated the Schmalkaldic League, an alliance of Protestant rulers. The Peace of Augsburg in 1555 brought recognition of the Lutheran faith. But the treaty also stipulated that the religion of a state was to be that of its ruler (Cuius regio, eius religio).

In 1608/1609 the Protestant Union and the Catholic League were formed.

From 1618 to 1648 the Thirty Years' War raged in the Holy Roman Empire. Its causes were the conflicts between Catholics and Protestants, the efforts by the various states within the Empire to increase their power, and the Catholic Emperor's attempt to achieve the religious and political unity of the Empire. The immediate occasion for the war was the uprising of the Protestant nobility of Bohemia against the emperor, but the conflict was widened into a European war by the intervention of King Christian IV of Denmark (1625–29), Gustavus Adolphus of Sweden (1630–48) and France under Cardinal Richelieu. Germany became the main theatre of war and the scene of the final conflict between France and the Habsburgs for predominance in Europe.

The fighting often was out of control, with marauding bands of hundreds or thousands of starving soldiers spreading plague, plunder, and murder. The armies that were under control moved back and forth across the countryside year after year, levying heavy taxes on cities, and seizing the animals and food stocks of the peasants without payment. The enormous social disruption over three decades caused a dramatic decline in population because of killings, disease, crop failures, declining birth rates and random destruction, and the out-migration of terrified people. One estimate shows a 38% drop from 16 million people in 1618 to 10 million by 1650, while another shows "only" a 20% drop from 20 million to 16 million. The Altmark and Württemberg regions were especially hard hit. It took generations for Germany to fully recover.

The war ended in 1648 with the Peace of Westphalia. Alsace was permanently lost to France, Pomerania was temporarily lost to Sweden, and the Netherlands officially left the Empire. Imperial power declined further as the states' rights were increased.

The German population reached about twenty million people, the great majority of whom were peasant farmers.

The Reformation was a triumph of literacy and the new printing press. Luther's translation of the Bible into German was a decisive moment in the spread of literacy, and stimulated as well the printing and distribution of religious books and pamphlets. From 1517 onward religious pamphlets flooded Germany and much of Europe. By 1530 over 10,000 publications are known, with a total of ten million copies. The Reformation was thus a media revolution. Luther strengthened his attacks on Rome by depicting a "good" against "bad" church. From there, it became clear that print could be used for propaganda in the Reformation for particular agendas. Reform writers used pre-Reformation styles, clichés, and stereotypes and changed items as needed for their own purposes. Especially effective were Luther's "Small Catechism", for use of parents teaching their children, and "Larger Catechism," for pastors. Using the German vernacular they expressed the Apostles' Creed in simpler, more personal, Trinitarian language. Illustrations in the newly translated Bible and in many tracts popularized Luther's ideas. Lucas Cranach the Elder (1472–1553), the great painter patronized by the electors of Wittenberg, was a close friend of Luther, and illustrated Luther's theology for a popular audience. He dramatized Luther's views on the relationship between the Old and New Testaments, while remaining mindful of Luther's careful distinctions about proper and improper uses of visual imagery.

Luther's German translation of the Bible was also decisive for the German language and its evolution from Early New High German to Modern Standard. His bible promoted the development of non-local forms of language and exposed all speakers to forms of German from outside their own area.

Decisive scientific developments took place during the 16th and 17th centuries, especially in the fields of astronomy, mathematics and physics. The German astronomical community played a dominant role in Europe at this time, as its scientists kept in close touch with one another. Several non-German scientists influenced this community too, like astronomers Copernicus who worked in Poland and Tycho Brahe, who worked in Denmark and Bohemia. Copernicus, for example, was better known inside the German community. Astronomer Johannes Kepler from Weil am Stadt was one of the leaders in the 17th-century scientific revolution. He is best known for his laws of planetary motion. His ideas influenced contemporary Italian scientist Galileo Galilei and provided one of the foundations for Englishman Isaac Newton's theory of universal gravitation.

From 1640, Brandenburg-Prussia had started to rise under the "Great Elector," Frederick William. The Peace of Westphalia in 1648 strengthened it even further, through the acquisition of East Pomerania. From 1713 to 1740, King Frederick William I, also known as the "Soldier King", established a highly centralized, militarized state with a heavily rural population of about three million (compared to the nine million in Austria).

In terms of the boundaries of 1914, Germany in 1700 had a population of 16 million, increasing slightly to 17 million by 1750, and growing more rapidly to 24 million by 1800. Wars continued, but they were no longer so devastating to the civilian population; famines and major epidemics did not occur, but increased agricultural productivity led to a higher birth rate, and a lower death rate.

Louis XIV of France conquered parts of Alsace and Lorraine (1678–1681), and had invaded and devastated the Electorate of the Palatinate (1688–1697) in the War of Palatinian Succession. Louis XIV benefited from the Empire's problems with the Turks, which were menacing Austria. Louis XIV ultimately had to relinquish the Electorate of the Palatinate. Afterwards Hungary was reconquered from the Turks; Austria, under the Habsburgs, developed into a great power.

Frederick II "the Great" is best known for his military genius, his reorganization of Prussian armies, his battlefield successes, his enlightened rule, and especially his making Prussia one of the great powers, as well as escaping from almost certain national disaster at the last minute. He was especially a role model for an aggressively expanding Germany down to 1945, and even today retains his heroic image in Germany.

In the War of Austrian Succession (1740–1748) Maria Theresa fought successfully for recognition of her succession to the throne. But in the Silesian Wars and in the Seven Years' War she had to cede 95% of Silesia to Frederick the Great. After the Peace of Hubertsburg in 1763 between Austria, Prussia and Saxony, Prussia won recognition as a great power, thus launching a century-long rivalry with Austria for the leadership of the German peoples.

From 1763, against resistance from the nobility and citizenry, an "enlightened absolutism" was established in Prussia and Austria, according to which the ruler governed according to the best precepts of the philosophers. The economies developed and legal reforms were undertaken, including the abolition of torture and the improvement in the status of Jews. Emancipation of the peasants slowly began. Compulsory education was instituted.

In 1772–1795 Prussia took the lead in the partitions of Poland, with Austria and Russia splitting the rest. Prussia occupied the western territories of the former Polish–Lithuanian Commonwealth that surrounded existing Prussian holdings. Poland again became independent in 1918.

Completely overshadowed by Prussia and Austria, according to historian Hajo Holborn, the smaller German states were generally characterized by political lethargy and administrative inefficiency, often compounded by rulers who were more concerned with their mistresses and their hunting dogs than with the affairs of state. Bavaria was especially unfortunate in this regard; it was a rural land with very heavy debts and few growth centers. Saxony was in economically good shape, although its government was seriously mismanaged, and numerous wars had taken their toll. During the time when Prussia rose rapidly within Germany, Saxony was distracted by foreign affairs. The house of Wettin concentrated on acquiring and then holding on to the Polish throne which was ultimately unsuccessful. In Württemberg the duke lavished funds on palaces, mistresses, great celebration, and hunting expeditions. Many of the city-states of Germany were run by bishops, who in reality were from powerful noble families and showed scant interest in religion. None developed a significant reputation for good government.

In Hesse-Kassel, the Landgrave Frederick II, ruled 1760–1785 as an enlightened despot, and raised money by renting soldiers (called "Hessians") to Great Britain to help fight the American Revolutionary War. He combined Enlightenment ideas with Christian values, cameralist plans for central control of the economy, and a militaristic approach toward diplomacy.

Hanover did not have to support a lavish court—its rulers were also kings of England and resided in London. George III, elector (ruler) from 1760 to 1820, never once visited Hanover. The local nobility who ran the country opened the University of Göttingen in 1737; it soon became a world-class intellectual center. Baden sported perhaps the best government of the smaller states. Karl Friedrich ruled well for 73 years (1738–1811) and was an enthusiast for The Enlightenment; he abolished serfdom in 1783.

The smaller states failed to form coalitions with each other, and were eventually overwhelmed by Prussia. Between 1807 and 1871, Prussia swallowed up many of the smaller states, with minimal protest, then went on to found the German Empire. In the process, Prussia became too heterogeneous, lost its identity, and by the 1930s had become an administrative shell of little importance.

In a heavily agrarian society, land ownership played a central role. Germany's nobles, especially those in the East – called Junkers – dominated not only the localities, but also the Prussian court, and especially the Prussian army. Increasingly after 1815, a centralized Prussian government based in Berlin took over the powers of the nobles, which in terms of control over the peasantry had been almost absolute. To help the nobility avoid indebtedness, Berlin set up a credit institution to provide capital loans in 1809, and extended the loan network to peasants in 1849. When the German Empire was established in 1871, the Junker nobility controlled the army and the Navy, the bureaucracy, and the royal court; they generally set governmental policies.

Peasants continued to center their lives in the village, where they were members of a corporate body, and to help manage the community resources and monitor the community life. In the East, they were serfs who were bound permanently to parcels of land. In most of Germany, farming was handled by tenant farmers who paid rents and obligatory services to the landlord, who was typically a nobleman. Peasant leaders supervised the fields and ditches and grazing rights, maintained public order and morals, and supported a village court which handled minor offenses. Inside the family the patriarch made all the decisions, and tried to arrange advantageous marriages for his children. Much of the villages' communal life centered around church services and holy days. In Prussia, the peasants drew lots to choose conscripts required by the army. The noblemen handled external relationships and politics for the villages under their control, and were not typically involved in daily activities or decisions.

The emancipation of the serfs came in 1770–1830, beginning with Schleswig in 1780. The peasants were now ex-serfs and could own their land, buy and sell it, and move about freely. The nobles approved for now they could buy land owned by the peasants. The chief reformer was Baron vom Stein (1757–1831), who was influenced by The Enlightenment, especially the free market ideas of Adam Smith. The end of serfdom raised the personal legal status of the peasantry. A bank was set up so that landowners could borrow government money to buy land from peasants (the peasants were not allowed to use it to borrow money to buy land until 1850). The result was that the large landowners obtained larger estates, and many peasants became landless tenants, or moved to the cities or to America. The other German states imitated Prussia after 1815. In sharp contrast to the violence that characterized land reform in the French Revolution, Germany handled it peacefully. In Schleswig the peasants, who had been influenced by the Enlightenment, played an active role; elsewhere they were largely passive. Indeed, for most peasants, customs and traditions continued largely unchanged, including the old habits of deference to the nobles whose legal authority remained quite strong over the villagers. Although the peasants were no longer tied to the same land as serfs had been, the old paternalistic relationship in East Prussia lasted into the 20th century.

The agrarian reforms in northwestern Germany in the era 1770–1870 were driven by progressive governments and local elites. They abolished feudal obligations and divided collectively owned common land into private parcels and thus created a more efficient market-oriented rural economy, which increased productivity and population growth and strengthened the traditional social order because wealthy peasants obtained most of the former common land, while the rural proletariat was left without land; many left for the cities or America. Meanwhile, the division of the common land served as a buffer preserving social peace between nobles and peasants. In the east the serfs were emancipated but the Junker class maintained its large estates and monopolized political power.

Around 1800 the Catholic monasteries, which had large land holdings, were nationalized and sold off by the government. In Bavaria they had controlled 56% of the land.

A major social change occurring between 1750–1850, depending on region, was the end of the traditional "whole house" ("ganzes Haus") system, in which the owner's family lived together in one large building with the servants and craftsmen he employed. They reorganized into separate living arrangements. No longer did the owner's wife take charge of all the females in the different families in the whole house. In the new system, farm owners became more professionalized and profit-oriented. They managed the fields and the household exterior according to the dictates of technology, science, and economics. Farm wives supervised family care and the household interior, to which strict standards of cleanliness, order, and thrift applied. The result was the spread of formerly urban bourgeois values into rural Germany.

The lesser families were now living separately on wages. They had to provide for their own supervision, health, schooling, and old-age. At the same time, because of the demographic transition, there were far fewer children, allowing for much greater attention to each child. Increasingly the middle-class family valued its privacy and its inward direction, shedding too-close links with the world of work. Furthermore, the working classes, the middle classes and the upper classes became physically, psychologically and politically more separate. This allowed for the emergence of working-class organizations. It also allowed for declining religiosity among the working-class, who were no longer monitored on a daily basis.

Before 1750 the German upper classes looked to France for intellectual, cultural and architectural leadership; French was the language of high society. By the mid-18th century the "Aufklärung" (German for "The Enlightenment") had transformed German high culture in music, philosophy, science and literature. Christian Wolff (1679–1754) was the pioneer as a writer who expounded the Enlightenment to German readers; he legitimized German as a philosophic language.

Prussia took the lead among the German states in sponsoring the political reforms that Enlightenment thinkers urged absolute rulers to adopt. However, there were important movements as well in the smaller states of Bavaria, Saxony, Hanover, and the Palatinate. In each case Enlightenment values became accepted and led to significant political and administrative reforms that laid the groundwork for the creation of modern states. The princes of Saxony, for example, carried out an impressive series of fundamental fiscal, administrative, judicial, educational, cultural, and general economic reforms. The reforms were aided by the country's strong urban structure and influential commercial groups, and modernized pre-1789 Saxony along the lines of classic Enlightenment principles.

Johann Gottfried von Herder (1744–1803) broke new ground in philosophy and poetry, as a leader of the Sturm und Drang movement of proto-Romanticism. Weimar Classicism ("Weimarer Klassik") was a cultural and literary movement based in Weimar that sought to establish a new humanism by synthesizing Romantic, classical, and Enlightenment ideas. The movement, from 1772 until 1805, involved Herder as well as polymath Johann Wolfgang von Goethe (1749–1832) and Friedrich Schiller (1759–1805), a poet and historian. Herder argued that every folk had its own particular identity, which was expressed in its language and culture. This legitimized the promotion of German language and culture and helped shape the development of German nationalism. Schiller's plays expressed the restless spirit of his generation, depicting the hero's struggle against social pressures and the force of destiny.

German music, sponsored by the upper classes, came of age under composers Johann Sebastian Bach (1685–1750), Joseph Haydn (1732–1809), and Wolfgang Amadeus Mozart (1756–1791).

In remote Königsberg philosopher Immanuel Kant (1724–1804) tried to reconcile rationalism and religious belief, individual freedom, and political authority. Kant's work contained basic tensions that would continue to shape German thought – and indeed all of European philosophy – well into the 20th century.

The German Enlightenment won the support of princes, aristocrats, and the middle classes, and it permanently reshaped the culture.

Before the 19th century, young women lived under the economic and disciplinary authority of their fathers until they married and passed under the control of their husbands. In order to secure a satisfactory marriage, a woman needed to bring a substantial dowry. In the wealthier families, daughters received their dowry from their families, whereas the poorer women needed to work in order to save their wages so as to improve their chances to wed. Under the German laws, women had property rights over their dowries and inheritances, a valuable benefit as high mortality rates resulted in successive marriages. Before 1789, the majority of women lived confined to society’s private sphere, the home.

The Age of Reason did not bring much more for women: men, including Enlightenment aficionados, believed that women were naturally destined to be principally wives and mothers. Within the educated classes, there was the belief that women needed to be sufficiently educated to be intelligent and agreeable interlocutors to their husbands. However, the lower-class women were expected to be economically productive in order to help their husbands make ends meet.

German reaction to the French Revolution was mixed at first. German intellectuals celebrated the outbreak, hoping to see the triumph of Reason and The Enlightenment. The royal courts in Vienna and Berlin denounced the overthrow of the king and the threatened spread of notions of liberty, equality, and fraternity. By 1793, the execution of the French king and the onset of the Terror disillusioned the Bildungsbürgertum (educated middle classes). Reformers said the solution was to have faith in the ability of Germans to reform their laws and institutions in peaceful fashion.

Europe was racked by two decades of war revolving around France's efforts to spread its revolutionary ideals, and the opposition of reactionary royalty. War broke out in 1792 as Austria and Prussia invaded France, but were defeated at the Battle of Valmy (1792). The German lands saw armies marching back and forth, bringing devastation (albeit on a far lower scale than the Thirty Years' War, almost two centuries before), but also bringing new ideas of liberty and civil rights for the people. Prussia and Austria ended their failed wars with France but (with Russia) partitioned Poland among themselves in 1793 and 1795. The French took control of the Rhineland, imposed French-style reforms, abolished feudalism, established constitutions, promoted freedom of religion, emancipated Jews, opened the bureaucracy to ordinary citizens of talent, and forced the nobility to share power with the rising middle class. Napoleon created the Kingdom of Westphalia (1807–1813) as a model state. These reforms proved largely permanent and modernized the western parts of Germany. When the French tried to impose the French language, German opposition grew in intensity. A Second Coalition of Britain, Russia, and Austria then attacked France but failed. Napoleon established direct or indirect control over most of western Europe, including the German states apart from Prussia and Austria. The old Holy Roman Empire was little more than a farce; Napoleon simply abolished it in 1806 while forming new countries under his control. In Germany Napoleon set up the "Confederation of the Rhine," comprising most of the German states except Prussia and Austria.

Prussia tried to remain neutral while imposing tight controls on dissent, but with German nationalism sharply on the rise, the small nation blundered by going to war with Napoleon in 1806. Its economy was weak, its leadership poor, and the once mighty Prussian army was a hollow shell. Napoleon easily crushed it at the Battle of Jena (1806). Napoleon occupied Berlin, and Prussia paid dearly. Prussia lost its recently acquired territories in western Germany, its army was reduced to 42,000 men, no trade with Britain was allowed, and Berlin had to pay Paris heavy reparations and fund the French army of occupation. Saxony changed sides to support Napoleon and join his Confederation of the Rhine; its elector was rewarded with the title of king and given a slice of Poland taken from Prussia.

After Napoleon's fiasco in Russia in 1812, including the deaths of many Germans in his invasion army, Prussia joined with Russia. Major battles followed in quick order, and when Austria switched sides to oppose Napoleon, his situation grew tenuous. He was defeated in a great Battle of Leipzig in late 1813, and Napoleon's empire started to collapse. One after another the German states switched to oppose Napoleon, but he rejected peace terms. Allied armies invaded France in early 1814, Paris fell, and in April Napoleon surrendered. He returned for 100 days in 1815, but was finally defeated by the British and German armies at Waterloo. Prussia was the big winner at the Vienna peace conference, gaining extensive territory.

Europe in 1815 was a continent in a state of complete exhaustion following the French Revolutionary and Napoleonic Wars, and started to turn from the liberal ideas of the Enlightenment and Revolutionary era and to Romanticism under such writers as Edmund Burke, Joseph de Maistre, and Novalis. Politically, the victorious allies set out to build a new balance of powers in order to keep the peace, and decided that a stable German region would be able to keep French imperialism at bay. To make this a possibility, the idea of reforming the defunct Holy Roman Empire was discarded, and Napoleon's reorganization of the German states was kept and the remaining princes were allowed to keep their titles. In 1813, in return for guarantees from the Allies that the sovereignty and integrity of the Southern German states (Baden, Württemberg, and Bavaria) would be preserved, they broke with the French.

The German Confederation () was the loose association of 39 states created in 1815 to coordinate the economies of separate German-speaking countries. It acted as a buffer between the powerful states of Austria and Prussia. Britain approved of it because London felt that there was need for a stable, peaceful power in central Europe that could discourage aggressive moves by France or Russia. According to Lee (1985), most historians have judged the Confederation to be weak and ineffective, as well as an obstacle to German nationalist aspirations. It collapsed because of the rivalry between Prussia and Austria (known as German dualism), warfare, the 1848 revolution, and the inability of the multiple members to compromise. It was replaced by the North German Confederation in 1866.

The population of the German Confederation (excluding Austria) grew 60% from 1815 to 1865, from 21,000,000 to 34,000,000. The era saw the Demographic Transition take place in Germany. It was a transition from high birth rates and high death rates to low birth and death rates as the country developed from a pre-industrial to a modernized agriculture and supported a fast-growing industrialized urban economic system. In previous centuries, the shortage of land meant that not everyone could marry, and marriages took place after age 25. After 1815, increased agricultural productivity meant a larger food supply, and a decline in famines, epidemics, and malnutrition. This allowed couples to marry earlier, and have more children. Arranged marriages became uncommon as young people were now allowed to choose their own marriage partners, subject to a veto by the parents. The high birthrate was offset by a very high rate of infant mortality and emigration, especially after about 1840, mostly to the German settlements in the United States, plus periodic epidemics and harvest failures. The upper and middle classes began to practice birth control, and a little later so too did the peasants.

Before 1850 Germany lagged far behind the leaders in industrial development – Britain, France, and Belgium. In 1800, Germany's social structure was poorly suited to entrepreneurship or economic development. Domination by France during the era of the French Revolution (1790s to 1815), however, produced important institutional reforms. Reforms included the abolition of feudal restrictions on the sale of large landed estates, the reduction of the power of the guilds in the cities, and the introduction of a new, more efficient commercial law. Nevertheless, traditionalism remained strong in most of Germany. Until mid-century, the guilds, the landed aristocracy, the churches, and the government bureaucracies had so many rules and restrictions that entrepreneurship was held in low esteem, and given little opportunity to develop. From the 1830s and 1840s, Prussia, Saxony, and other states reorganized agriculture. The introduction of sugar beets, turnips, and potatoes yielded a higher level of food production, which enabled a surplus rural population to move to industrial areas. The beginnings of the industrial revolution in Germany came in the textile industry, and was facilitated by eliminating tariff barriers through the Zollverein, starting in 1834.

By mid-century, the German states were catching up. By 1900 Germany was a world leader in industrialization, along with Britain and the United States. Historian Thomas Nipperdey sums it up:

Industrialization brought rural Germans to the factories, mines and railways. The population in 1800 was heavily rural, with only 10% of the people living in communities of 5000 or more people, and only 2% living in cities of more than 100,000. After 1815, the urban population grew rapidly, due primarily to the influx of young people from the rural areas. Berlin grew from 172,000 in 1800, to 826,000 in 1870; Hamburg grew from 130,000 to 290,000; Munich from 40,000 to 269,000; and Dresden from 60,000 to 177,000. Offsetting this growth, there was extensive emigration, especially to the United States. Emigration totaled 480,000 in the 1840s, 1,200,000 in the 1850s, and 780,000 in the 1860s.

The takeoff stage of economic development came with the railroad revolution in the 1840s, which opened up new markets for local products, created a pool of middle managers, increased the demand for engineers, architects and skilled machinists and stimulated investments in coal and iron. Political disunity of three dozen states and a pervasive conservatism made it difficult to build railways in the 1830s. However, by the 1840s, trunk lines did link the major cities; each German state was responsible for the lines within its own borders. Economist Friedrich List summed up the advantages to be derived from the development of the railway system in 1841:

Lacking a technological base at first, the Germans imported their engineering and hardware from Britain, but quickly learned the skills needed to operate and expand the railways. In many cities, the new railway shops were the centres of technological awareness and training, so that by 1850, Germany was self-sufficient in meeting the demands of railroad construction, and the railways were a major impetus for the growth of the new steel industry. Observers found that even as late as 1890, their engineering was inferior to Britain’s. However, German unification in 1870 stimulated consolidation, nationalisation into state-owned companies, and further rapid growth. Unlike the situation in France, the goal was support of industrialisation, and so, heavy lines crisscrossed the Ruhr and other industrial districts, and provided good connections to the major ports of Hamburg and Bremen. By 1880, Germany had 9,400 locomotives pulling 43,000 passengers and 30,000 tons of freight a day, and forged ahead of France.

A large number of newspapers and magazines flourished; A typical small city had one or two newspapers; Berlin and Leipzig had dozens. The audience was limited to perhaps five percent of the adult men, chiefly from the aristocratic and middle classes, who followed politics. Liberal papers outnumbered conservative ones by a wide margin. Foreign governments bribed editors to guarantee a favorable image. Censorship was strict, and the government issued the political news they were supposed to report. After 1871, strict press laws were used by Bismarck to shut down the Socialist, and to threaten hostile editors. There were no national newspapers. Editors focused on political commentary, but also included in a nonpolitical cultural page, focused on the arts and high culture. Especially popular was the serialized novel, with a new chapter every week. Magazines were politically more influential, and attracted the leading intellectuals as authors.

German artists and intellectuals, heavily influenced by the French Revolution and by the great German poet and writer Johann Wolfgang von Goethe (1749–1832), turned to Romanticism after a period of Enlightenment. Philosophical thought was decisively shaped by Immanuel Kant (1724–1804). Ludwig van Beethoven (1770–1827) was the leading composer of Romantic music. His use of tonal architecture in such a way as to allow significant expansion of musical forms and structures was immediately recognized as bringing a new dimension to music. His later piano music and string quartets, especially, showed the way to a completely unexplored musical universe, and influenced Franz Schubert (1797–1828) and Robert Schumann (1810–1856). In opera, a new Romantic atmosphere combining supernatural terror and melodramatic plot in a folkloric context was first successfully achieved by Carl Maria von Weber (1786–1826) and perfected by Richard Wagner (1813–1883) in his Ring Cycle. The Brothers Grimm (1785–1863 & 1786–1859) not only collected folk stories into the popular Grimm's Fairy Tales, but were also linguists, now counted among the founding fathers of German studies. They were commissioned to begin the Deutsches Wörterbuch ("The German Dictionary"), which remains the most comprehensive work on the German language.

At the universities high-powered professors developed international reputations, especially in the humanities led by history and philology, which brought a new historical perspective to the study of political history, theology, philosophy, language, and literature. With Georg Wilhelm Friedrich Hegel (1770–1831) in philosophy, Friedrich Schleiermacher (1768–1834) in theology and Leopold von Ranke (1795–1886) in history, the University of Berlin, founded in 1810, became the world's leading university. Von Ranke, for example, professionalized history and set the world standard for historiography. By the 1830s mathematics, physics, chemistry, and biology had emerged with world class science, led by Alexander von Humboldt (1769–1859) in natural science and Carl Friedrich Gauss (1777–1855) in mathematics. Young intellectuals often turned to politics, but their support for the failed Revolution of 1848 forced many into exile.

Two main developments reshaped religion in Germany. Across the land, there was a movement to unite the larger Lutheran and the smaller Reformed Protestant churches. The churches themselves brought this about in Baden, Nassau, and Bavaria. However, in Prussia King Frederick William III was determined to handle unification entirely on his own terms, without consultation. His goal was to unify the Protestant churches, and to impose a single standardized liturgy, organization and even architecture. The long-term goal was to have fully centralized royal control of all the Protestant churches. In a series of proclamations over several decades the "Church of the Prussian Union" was formed, bringing together the more numerous Lutherans, and the less numerous Reformed Protestants. The government of Prussia now had full control over church affairs, with the king himself recognized as the leading bishop. Opposition to unification came from the "Old Lutherans" in Silesia who clung tightly to the theological and liturgical forms they had followed since the days of Luther. The government attempted to crack down on them, so they went underground. Tens of thousands migrated, to South Australia, and especially to the United States, where they formed the Missouri Synod, which is still in operation as a conservative denomination. Finally in 1845 a new king Frederick William IV offered a general amnesty and allowed the Old Lutherans to form a separate church association with only nominal government control.

From the religious point of view of the typical Catholic or Protestant, major changes were underway in terms of a much more personalized religiosity that focused on the individual more than the church or the ceremony. The rationalism of the late 19th century faded away, and there was a new emphasis on the psychology and feeling of the individual, especially in terms of contemplating sinfulness, redemption, and the mysteries and the revelations of Christianity. Pietistic revivals were common among Protestants. Among Catholics there was a sharp increase in popular pilgrimages. In 1844 alone, half a million pilgrims made a pilgrimage to the city of Trier in the Rhineland to view the Seamless robe of Jesus, said to be the robe that Jesus wore on the way to his crucifixion. Catholic bishops in Germany had historically been largely independent Of Rome, but now the Vatican exerted increasing control, a new "ultramontanism" of Catholics highly loyal to Rome. A sharp controversy broke out in 1837–38 in the largely Catholic Rhineland over the religious education of children of mixed marriages, where the mother was Catholic and the father Protestant. The government passed laws to require that these children always be raised as Protestants, contrary to Napoleonic law that had previously prevailed and allowed the parents to make the decision. It put the Catholic Archbishop under house arrest. In 1840, the new King Frederick William IV sought reconciliation and ended the controversy by agreeing to most of the Catholic demands. However Catholic memories remained deep and led to a sense that Catholics always needed to stick together in the face of an untrustworthy government.

After the fall of Napoleon, Europe's statesmen convened in Vienna in 1815 for the reorganisation of European affairs, under the leadership of the Austrian Prince Metternich. The political principles agreed upon at this Congress of Vienna included the restoration, legitimacy and solidarity of rulers for the repression of revolutionary and nationalist ideas.

The German Confederation () was founded, a loose union of 39 states (35 ruling princes and 4 free cities) under Austrian leadership, with a Federal Diet () meeting in Frankfurt am Main. It was a loose coalition that failed to satisfy most nationalists. The member states largely went their own way, and Austria had its own interests.

In 1819 a student radical assassinated the reactionary playwright August von Kotzebue, who had scoffed at liberal student organisations. In one of the few major actions of the German Confederation, Prince Metternich called a conference that issued the repressive Carlsbad Decrees, designed to suppress liberal agitation against the conservative governments of the German states. The Decrees terminated the fast-fading nationalist fraternities (), removed liberal university professors, and expanded the censorship of the press. The decrees began the "persecution of the demagogues", which was directed against individuals who were accused of spreading revolutionary and nationalist ideas. Among the persecuted were the poet Ernst Moritz Arndt, the publisher Johann Joseph Görres and the "Father of Gymnastics" Ludwig Jahn.
In 1834 the Zollverein was established, a customs union between Prussia and most other German states, but excluding Austria. As industrialisation developed, the need for a unified German state with a uniform currency, legal system, and government became more and more obvious.

Growing discontent with the political and social order imposed by the Congress of Vienna led to the outbreak, in 1848, of the March Revolution in the German states. In May the German National Assembly (the Frankfurt Parliament) met in Frankfurt to draw up a national German constitution.

But the 1848 revolution turned out to be unsuccessful: King Frederick William IV of Prussia refused the imperial crown, the Frankfurt parliament was dissolved, the ruling princes repressed the risings by military force, and the German Confederation was re-established by 1850. Many leaders went into exile, including a number who went to the United States and became a political force there.

The 1850s were a period of extreme political reaction. Dissent was vigorously suppressed, and many Germans emigrated to America following the collapse of the 1848 uprisings. Frederick William IV became extremely depressed and melancholy during this period, and was surrounded by men who advocated clericalism and absolute divine monarchy. The Prussian people once again lost interest in politics. Prussia not only expanded its territory but began to industrialize rapidly, while maintaining a strong agricultural base.

In 1857, the king had a stroke and his brother William became regent, then became King William I in 1861. Although conservative, William I was far more pragmatic. His most significant accomplishment was naming Otto von Bismarck as chancellor in 1862. The combination of Bismarck, Defense Minister Albrecht von Roon, and Field Marshal Helmut von Moltke set the stage for victories over Denmark, Austria, and France, and led to the unification of Germany. The obstacle to German unification was Austria, and Bismarck solved the problem with a series of wars that united the German states north of Austria.

In 1863–64, disputes between Prussia and Denmark grew over Schleswig, which was not part of the German Confederation, and which Danish nationalists wanted to incorporate into the Danish kingdom. The dispute led to the short Second War of Schleswig in 1864. Prussia, joined by Austria, easily defeated Denmark and occupied Jutland. The Danes were forced to cede both the duchy of Schleswig and the duchy of Holstein to Austria and Prussia. In the aftermath, the management of the two duchies caused escalating tensions between Austria and Prussia. The former wanted the duchies to become an independent entity within the German Confederation, while the latter wanted to annex them. The Seven Weeks War between Austria and Prussia broke out in June 1866. In July, the two armies clashed at Sadowa-Königgrätz (Bohemia) in an enormous battle involving half a million men. The Prussian breech-loading needle guns carried the day over the slow muzzle-loading rifles of the Austrians, who lost a quarter of their army in the battle. Austria ceded Venice to Italy, but Bismarck was deliberately lenient with the loser to keep alive a long-term alliance with Austria in a subordinate role. Now the French faced an increasingly strong Prussia.

In 1866, the German Confederation was dissolved. In its place the North German Federation (German "Norddeutscher Bund") was established, under the leadership of Prussia. Austria was excluded, and the Austrian influence in Germany that had begun in the 15th century finally came to an end. The North German Federation was a transitional organisation that existed from 1867 to 1871, between the dissolution of the German Confederation and the founding of the German Empire.

After Germany was united by Otto von Bismarck into the "German Reich", he determined German politics until 1890. Bismarck tried to foster alliances in Europe, on one hand to contain France, and on the other hand to consolidate Germany's influence in Europe. On the domestic front Bismarck tried to stem the rise of socialism by anti-socialist laws, combined with an introduction of health care and social security. At the same time Bismarck tried to reduce the political influence of the emancipated Catholic minority in the Kulturkampf, literally "culture struggle". The Catholics only grew stronger, forming the Center (Zentrum) Party. Germany grew rapidly in industrial and economic power, matching Britain by 1900. Its highly professional army was the best in the world, but the navy could never catch up with Britain's Royal Navy.

In 1888, the young and ambitious Kaiser Wilhelm II became emperor. He could not abide advice, least of all from the most experienced politician and diplomat in Europe, so he fired Bismarck. The Kaiser opposed Bismarck's careful foreign policy and wanted Germany to pursue colonialist policies, as Britain and France had been doing for decades, as well as build a navy that could match the British. The Kaiser promoted active colonization of Africa and Asia for those areas that were not already colonies of other European powers; his record was notoriously brutal and set the stage for genocide. The Kaiser took a mostly unilateral approach in Europe with as main ally the Austro-Hungarian Empire, and an arms race with Britain, which eventually led to the situation in which the assassination of the Austrian-Hungarian crown prince could spark off World War I.

Disputes between France and Prussia increased. In 1868, the Spanish queen Isabella II was expelled by a revolution, leaving that country's throne vacant. When Prussia tried to put a Hohenzollern candidate, Prince Leopold, on the Spanish throne, the French angrily protested. In July 1870, France declared war on Prussia (the Franco-Prussian War). The debacle was swift. A succession of German victories in northeastern France followed, and one French army was besieged at Metz. After a few weeks, the main army was finally forced to capitulate in the fortress of Sedan. French Emperor Napoleon III was taken prisoner and a republic hastily proclaimed in Paris. The new government, realising that a victorious Germany would demand territorial acquisitions, resolved to fight on. They began to muster new armies, and the Germans settled down to a grim siege of Paris. The starving city surrendered in January 1871, and the Prussian army staged a victory parade in it. France was forced to pay indemnities of 5 billion francs and cede Alsace-Lorraine. It was a bitter peace that would leave the French thirsting for revenge.

During the Siege of Paris, the German princes assembled in the Hall of Mirrors of the Palace of Versailles and proclaimed the Prussian King Wilhelm I as the "German Emperor" on 18 January 1871. The German Empire was thus founded, with the German states unified into a single economic, political, and administrative unit. The empire comprised 25 states, three of which were Hanseatic free cities. It was dubbed the "Little German" solution, since it excluded the Austrian territories and the Habsburgs. Bismarck, again, was appointed to serve as Chancellor.

The new empire was characterised by a great enthusiasm and vigor. There was a rash of heroic artwork in imitation of Greek and Roman styles, and the nation possessed a vigorous, growing industrial economy, while it had always been rather poor in the past. The change from the slower, more tranquil order of the old Germany was very sudden, and many, especially the nobility, resented being displaced by the new rich. And yet, the nobles clung stubbornly to power, and they, not the bourgeois, continued to be the model that everyone wanted to imitate. In imperial Germany, possessing a collection of medals or wearing a uniform was valued more than the size of one's bank account, and Berlin never became a great cultural center as London, Paris, or Vienna were. The empire was distinctly authoritarian in tone, as the 1871 constitution gave the emperor exclusive power to appoint or dismiss the chancellor. He also was supreme commander-in-chief of the armed forces and final arbiter of foreign policy. But freedom of speech, association, and religion were nonetheless guaranteed by the constitution.

Bismarck's domestic policies as Chancellor of Germany were characterised by his fight against perceived enemies of the Protestant Prussian state. In the Kulturkampf (1871–1878), he tried to minimize the influence of the Roman Catholic Church and of its political arm, the Catholic Centre Party, through various measures—like the introduction of civil marriage—but without much success. The Kulturkampf antagonised many Protestants as well as Catholics, and was eventually abandoned. Millions of non-Germans subjects in the German Empire, like the Polish, Danish and French minorities, were discriminated against, and a policy of Germanisation was implemented.

The new Empire provided rich new opportunities at the top for the nobility of Prussia, and the other states, to fill. They dominated the diplomatic service, the Army, and the civil service. Through their control of the civil service, the aristocracy had a dominant voice in decisions affecting the universities and the churches. In 1914, Germany's diplomats consisted of eight princes 29 counts 20 barons 54 other nobles, and a mere 11 commoners. The commoners were chiefly the sons of leading industrialists or bankers. Almost all the diplomats had been socialized into the feudal student corps at the universities. The consular corps comprised commoners, but they had little decision-making ability. Since the days of Frederick the great, it had been difficult for commoners to achieve high ranking the Army. It was considered a suitable role for young aristocrats. The new Constitution put Military affairs under the direct control of the Emperor, and largely out of reach of the Reichstag. With its large corps of reserve officers across Germany, the military strengthened its role as "The estate which upheld the nation." Historian Hans-Ulrich Wehler says, "it became an almost separate, self-perpetuating caste."

Power increasingly was centralized in the national capital of Berlin (including neighboring Potsdam.) where 7000 aristocrats drew a sharp line between themselves and everyone else. Berlin's rapidly increasing rich middle-class aped and copied the aristocracy and tried to marry into it. The closed system stood in contrast to Britain where the top levels of the elite were far more open with routes available through a public school education, Oxford, and Cambridge, the Inns of Court, appointment to high office, or leadership in the House of Commons. A peerage could permanently boost a rich industrial family into the upper reaches of the establishment. In Germany, the process worked in the other direction as the nobility became industrialists. For example, 221 of the 243 mines in Silesia were owned by nobles or by the King of Prussia himself.

Germany's middle class, based in the cities, grew exponentially, although it never gained the political power it had in France, Britain or the United States. The Bund Deutscher Frauenvereine (Association of German Women's Organizations or BDF) was established in 1894 to encompass the proliferating women's organizations that had sprung up since the 1860s. From the beginning the BDF was a bourgeois organization, its members working toward equality with men in such areas as education, financial opportunities, and political life. Working-class women were not welcome; they were organized by the Socialists.

The rise of the Socialist Workers' Party (later known as the Social Democratic Party of Germany, SPD), declared its aim to establish peacefully a new socialist order through the transformation of existing political and social conditions. From 1878, Bismarck tried to repress the social democratic movement by outlawing the party's organisation, its assemblies and most of its newspapers. When it finally was allowed to run candidates, the Social Democrats were stronger than ever.

Bismarck built on a tradition of welfare programs in Prussia and Saxony that began as early as the 1840s. In the 1880s he introduced old age pensions, accident insurance, medical care, and unemployment insurance that formed the basis of the modern European welfare state. His paternalistic programs won the support of German industry because its goals were to win the support of the working classes for the Empire and reduce the outflow of immigrants to America, where wages were higher but welfare did not exist. Bismarck further won the support of both industry and skilled workers by his high tariff policies, which protected profits and wages from American competition, although they alienated the liberal intellectuals who wanted free trade.

Bismarck would not tolerate any power outside Germany—as in Rome—having a say in German affairs. He launched a Kulturkampf ("culture war") against the power of the pope and the Catholic Church in 1873, but only in Prussia. This gained strong support from German liberals, who saw the Catholic Church as the bastion of reaction and their greatest enemy. The Catholic element, in turn, saw in the National-Liberals as its worst enemy and formed the Center Party.

Catholics, although nearly a third of the national population, were seldom allowed to hold major positions in the Imperial government, or the Prussian government. After 1871, there was a systematic purge of the remaining Catholics; in the powerful interior ministry, which handled all police affairs, the only Catholic was a messenger boy. Jews were likewise heavily discriminated against.

Most of the Kulturkampf was fought out in Prussia, but Imperial Germany passed the Pulpit Law which made it a crime for any cleric to discuss public issues in a way that displeased the government. Nearly all Catholic bishops, clergy, and laymen rejected the legality of the new laws and defiantly faced the increasingly heavy penalties and imprisonments imposed by Bismarck's government. Historian Anthony Steinhoff reports the casualty totals:

Bismarck underestimated the resolve of the Catholic Church and did not foresee the extremes that this struggle would attain. The Catholic Church denounced the harsh new laws as anti-Catholic and mustered the support of its rank and file voters across Germany. In the following elections, the Center Party won a quarter of the seats in the Imperial Diet. The conflict ended after 1879 because Pope Pius IX died in 1878 and Bismarck broke with the Liberals to put his main emphasis on tariffs, foreign policy, and attacking socialists. Bismarck negotiated with the conciliatory new pope Leo XIII. Peace was restored, the bishops returned and the jailed clerics were released. Laws were toned down or taken back (Mitigation Laws 1880–1883 and Peace Laws 1886/87), but the laws concerning education, civil registry of marriages and religious disaffiliation remained in place. The Center Party gained strength and became an ally of Bismarck, especially when he attacked socialism.

Bismarck's post-1871 foreign policy was conservative and basically aimed at security and preventing the dreaded scenario of a Franco-Russian alliance, which would trap Germany between the two in a war.
The League of Three Emperors ("Dreikaisersbund") was signed in 1872 by Russia, Austria, and Germany. It stated that republicanism and socialism were common enemies and that the three powers would discuss any matters concerning foreign policy. Bismarck needed good relations with Russia in order to keep France isolated. In 1877–1878, Russia fought a victorious war with the Ottoman Empire and attempted to impose the Treaty of San Stefano on it. This upset the British in particular, as they were long concerned with preserving the Ottoman Empire and preventing a Russian takeover of the Bosphorus Strait. Germany hosted the Congress of Berlin (1878), whereby a more moderate peace settlement was agreed to. Germany had no direct interest in the Balkans, however, which was largely an Austrian and Russian sphere of influence, although King Carol of Romania was a German prince.

In 1879, Bismarck formed a Dual Alliance of Germany and Austria-Hungary, with the aim of mutual military assistance in the case of an attack from Russia, which was not satisfied with the agreement reached at the Congress of Berlin. The establishment of the Dual Alliance led Russia to take a more conciliatory stance, and in 1887, the so-called Reinsurance Treaty was signed between Germany and Russia: in it, the two powers agreed on mutual military support in the case that France attacked Germany, or in case of an Austrian attack on Russia. Russia turned its attention eastward to Asia and remained largely inactive in European politics for the next 25 years. In 1882, Italy joined the Dual Alliance to form a Triple Alliance. Italy wanted to defend its interests in North Africa against France's colonial policy. In return for German and Austrian support, Italy committed itself to assisting Germany in the case of a French military attack.

For a long time, Bismarck had refused to give in to widespread public demands to give Germany "a place in the sun" through the acquisition of overseas colonies. In 1880 Bismarck gave way, and a number of colonies were established overseas. In Africa, these were Togo, the Cameroons, German South-West Africa, and German East Africa; in Oceania, they were German New Guinea, the Bismarck Archipelago, and the Marshall Islands. In fact, it was Bismarck himself who helped initiate the Berlin Conference of 1885. He did it to "establish international guidelines for the acquisition of African territory" (see Colonisation of Africa). This conference was an impetus for the "Scramble for Africa" and "New Imperialism".

In 1888, emperor William I died at the age of 90. His son Frederick III, the hope of German liberals, was already stricken with throat cancer and died three months later. Frederick's son Wilhelm II then became emperor at the age of 29. Having had a problematic relationship with his liberal parents, Wilhelm had early on decided to renew the top level of the state. The two years that Bismarck remained in office feigned continuity, but a difference of opinion on social politics served as an excuse for the young Kaiser to force the chancellor into retirement in March 1890. Following a principle known as "personal regiment" (German: "persönliches Regiment"), Wilhelm aimed to exercise influence on every government decision.

The young Kaiser Wilhelm sought aggressively to increase Germany's influence in the world ("Weltpolitik"). After the removal of Bismarck, foreign policy was in the hands of the erratic Kaiser, who played an increasingly reckless hand, and the powerful foreign office under the leadership of Friedrich von Holstein. The foreign office argued that: first, a long-term coalition between France and Russia had to fall apart; secondly, Russia and Britain would never get together; and, finally, Britain would eventually seek an alliance with Germany. Germany refused to renew its treaties with Russia. But Russia did form a closer relationship with France in the Dual Alliance of 1894, since both were worried about the possibilities of German aggression. Furthermore, Anglo–German relations cooled as Germany aggressively tried to build a new empire and engaged in a naval race with Britain; London refused to agree to the formal alliance that Germany sought. Berlin's analysis proved mistaken on every point, leading to Germany's increasing isolation and its dependence on the Triple Alliance, which brought together Germany, Austria-Hungary, and Italy. The Triple Alliance was undermined by differences between Austria and Italy, and in 1915 Italy switched sides.

Meanwhile, the German Navy under Admiral Alfred von Tirpitz had ambitions to rival the great British Navy, and dramatically expanded its fleet in the early 20th century to protect the colonies and exert power worldwide. Tirpitz started a programme of warship construction in 1898. In 1890, Germany had gained the island of Heligoland in the North Sea from Britain in exchange for the eastern African island of Zanzibar, and proceeded to construct a great naval base there. This posed a direct threat to British hegemony on the seas, with the result that negotiations for an alliance between Germany and Britain broke down. The British, however, kept well ahead in the naval race by the introduction of the highly advanced new "Dreadnought" battleship in 1907.

In the First Moroccan Crisis of 1905, Germany nearly came to blows with Britain and France when the latter attempted to establish a protectorate over Morocco. The Germans were upset at having not been informed about French intentions, and declared their support for Moroccan independence. William II made a highly provocative speech regarding this. The following year, a conference was held in which all of the European powers except Austria-Hungary (by now little more than a German satellite) sided with France. A compromise was brokered by the United States where the French relinquished some, but not all, control over Morocco.

The Second Moroccan Crisis of 1911 saw another dispute over Morocco erupt when France tried to suppress a revolt there. Germany, still smarting from the previous quarrel, agreed to a settlement whereby the French ceded some territory in central Africa in exchange for Germany's renouncing any right to intervene in Moroccan affairs. This confirmed French control over Morocco, which became a full protectorate of that country in 1912.

The economy continued to industrialize and urbanize, with heavy industry – especially coal and steel – becoming important in the Ruhr, and manufacturing growing in the cities, the Ruhr, and Silesia. Perkins (1981) argues that more important than Bismarck's new tariff on imported grain was the introduction of the sugar beet as a main crop. Farmers quickly abandoned traditional, inefficient practices in favor of modern methods, including use of new fertilizers and new tools. The knowledge and tools gained from the intensive farming of sugar and other root crops made Germany the most efficient agricultural producer in Europe by 1914. Even so, farms were small in size, and women did much of the field work. An unintended consequence was the increased dependence on migratory, especially foreign, labor.
Based on its leadership in chemical research in the universities and industrial laboratories, Germany became dominant in the world's chemical industry in the late 19th century. At first, the production of dyes was critical.

Germany became Europe's leading steel-producing nation in the 1890s, thanks in large part to the protection from American and British competition afforded by tariffs and cartels. The leading firm was "Friedrich Krupp AG Hoesch-Krupp," run by the Krupp family. The merger of several major firms into the "Vereinigte Stahlwerke" (United Steel Works) in 1926 was modeled on the U.S. Steel corporation in the United States. The new company emphasized rationalization of management structures and modernization of the technology; it employed a multi-divisional structure and used return on investment as its measure of success. By 1913, American and German exports dominated the world steel market, as Britain slipped to third place.

In machinery, iron and steel, and other industries, German firms avoided cut-throat competition and instead relied on trade associations. Germany was a world leader because of its prevailing "corporatist mentality", its strong bureaucratic tradition, and the encouragement of the government. These associations regulate competition and allowed small firms to function in the shadow of much larger companies.

Germany's unification process after 1871 was heavily dominated by men and give priority to the "Fatherland" theme and related male issues, such as military prowess. Nevertheless, middle class women enrolled in the "Bund Deutscher Frauenvereine", the Union of German Feminist Organizations (BDF). Founded in 1894, it grew to include 137 separate women's rights groups from 1907 until 1933, when the Nazi regime disbanded the organization. The BDF gave national direction to the proliferating women's organizations that had sprung up since the 1860s. From the beginning the BDF was a bourgeois organization, its members working toward equality with men in such areas as education, financial opportunities, and political life. Working-class women were not welcome; they were organized by the Socialists.

Formal organizations for promoting women's rights grew in numbers during the Wilhelmine period. German feminists began to network with feminists from other countries, and participated in the growth of international organizations.

By the 1890s, German colonial expansion in Asia and the Pacific (Kiauchau in China, the Marianas, the Caroline Islands, Samoa) led to frictions with Britain, Russia, Japan and the United States. The construction of the Baghdad Railway, financed by German banks, was designed to eventually connect Germany with the Turkish Empire and the Persian Gulf, but it also collided with British and Russian geopolitical interests.

The largest colonial enterprises were in Africa. The harsh treatment of the Nama and Herero in what is now Namibia in Africa in 1906–07 led to charges of genocide against the Germans. Historians are examining the links and precedents between the Herero and Namaqua Genocide and the Holocaust of the 1940s.

Ethnic demands for nation states upset the balance between the empires that dominated Europe, leading to World War I, which started in August 1914. Germany stood behind its ally Austria in a confrontation with Serbia, but Serbia was under the protection of Russia, which was allied to France. Germany was the leader of the Central Powers, which included Austria-Hungary, the Ottoman Empire, and later Bulgaria; arrayed against them were the Allies, consisting chiefly of Russia, France, Britain, and in 1915 Italy.

In explaining why neutral Britain went to war with Germany, Kennedy (1980) recognized it was critical for war that Germany become economically more powerful than Britain, but he downplays the disputes over economic trade imperialism, the Baghdad Railway, confrontations in Central and Eastern Europe, high-charged political rhetoric and domestic pressure-groups. Germany's reliance time and again on sheer power, while Britain increasingly appealed to moral sensibilities, played a role, especially in seeing the invasion of Belgium as a necessary military tactic or a profound moral crime. The German invasion of Belgium was not important because the British decision had already been made and the British were more concerned with the fate of France (pp. 457–62). Kennedy argues that by far the main reason was London's fear that a repeat of 1870 — when Prussia and the German states smashed France — would mean that Germany, with a powerful army and navy, would control the English Channel and northwest France. British policy makers insisted that would be a catastrophe for British security.

In the west, Germany sought a quick victory by encircling Paris using the Schlieffen Plan. But it failed due to Belgian resistance, Berlin's diversion of troops, and very stiff French resistance on the Marne, north of Paris.

The Western Front became an extremely bloody battleground of trench warfare. The stalemate lasted from 1914 until early 1918, with ferocious battles that moved forces a few hundred yards at best along a line that stretched from the North Sea to the Swiss border. The British imposed a tight naval blockade in the North Sea which lasted until 1919, sharply reducing Germany's overseas access to raw materials and foodstuffs. Food scarcity became a serious problem by 1917.

The United States joined with the Allies in April 1917. The entry of the United States into the war – following Germany's declaration of unrestricted submarine warfare – marked a decisive turning-point against Germany.

More wide open was the fighting on the Eastern Front. In the east, there were decisive victories against the Russian army, the trapping and defeat of large parts of the Russian contingent at the Battle of Tannenberg, followed by huge Austrian and German successes. The breakdown of Russian forces – exacerbated by internal turmoil caused by the 1917 Russian Revolution – led to the Treaty of Brest-Litovsk the Bolsheviks were forced to sign on 3 March 1918 as Russia withdrew from the war. It gave Germany control of Eastern Europe. Spencer Tucker says, "The German General Staff had formulated extraordinarily harsh terms that shocked even the German negotiator." When Germany later complained that the Treaty of Versailles of 1919 was too harsh on them, the Allies responded that it was more benign than Brest-Litovsk.

By defeating Russia in 1917 Germany was able to bring hundreds of thousands of combat troops from the east to the Western Front, giving it a numerical advantage over the Allies. By retraining the soldiers in new storm-trooper tactics, the Germans expected to unfreeze the Battlefield and win a decisive victory before the American army arrived in strength. However, the spring offensives all failed, as the Allies fell back and regrouped, and the Germans lacked the reserves necessary to consolidate their gains. In the summer, with the Americans arriving at 10,000 a day, and the German reserves exhausted, it was only a matter of time before multiple Allied offenses destroyed the German army.

Unexpectedly Germany plunged into World War I (1914–1918). It rapidly mobilized its civilian economy for the war effort, the economy was handicapped by the British blockade that cut off food supplies.
Meanwhile, conditions deteriorated rapidly on the home front, with severe food shortages reported in all urban areas. Causes involved the transfer of many farmers and food workers into the military, an overburdened railroad system, shortages of coal, and the British blockade that cut off imports from abroad. The winter of 1916–1917 was known as the "turnip winter," because that vegetable, usually fed to livestock, was used by people as a substitute for potatoes and meat, which were increasingly scarce. Thousands of soup kitchens were opened to feed the hungry people, who grumbled that the farmers were keeping the food for themselves. Even the army had to cut the rations for soldiers. Morale of both civilians and soldiers continued to sink.

1918 was also the year of the deadly 1918 Spanish Flu pandemic which struck hard at a population weakened by years of malnutrition.

The end of October 1918, in Wilhelmshaven, in northern Germany, saw the beginning of the German Revolution of 1918–19. Units of the German Navy refused to set sail for a last, large-scale operation in a war which they saw as good as lost, initiating the uprising. On 3 November, the revolt spread to other cities and states of the country, in many of which workers' and soldiers' councils were established. Meanwhile, Hindenburg and the senior commanders had lost confidence in the Kaiser and his government. The Kaiser and all German ruling princes abdicated. On 9 November 1918, the Social Democrat Philipp Scheidemann proclaimed a Republic.
On 11 November, the Compiègne armistice was signed, ending the war. The Treaty of Versailles was signed on 28 June 1919. Germany was to cede Alsace-Lorraine to France. Eupen-Malmédy would temporarily be ceded to Belgium, with a plebiscite to be held to allow the people the choice of the territory either remaining with Belgium or being returned to German control. Following a plebiscite, the territory was allotted to Belgium on 20 September 1920. The future of North Schleswig was to be decided by plebiscite. In the Schleswig Plebiscites, the Danish-speaking population in the north voted for Denmark and the southern, German speaking populace, part voted for Germany. Schleswig was thus partitioned. Holstein remained German without a referendum. Memel was ceded to the Allied and Associated powers, to decide the future of the area. On 9 January 1923, Lithuanian forces invaded the territory. Following negotiations, on 8 May 1924, the League of Nations ratified the annexation on the grounds that Lithuania accepted the Memel Statute, a power-sharing arrangement to protect non-Lithuanians in the territory and its autonomous status. Until 1929, German-Lithuanian co-operation increased and this power sharing arrangement worked. Poland was restored and most of the provinces of Posen and West Prussia, and some areas of Upper Silesia were reincorporated into the reformed country after plebiscites and independence uprisings. All German colonies were to be handed over to League of Nations, who then assigned them as Mandates to Australia, France, Japan, New Zealand, Portugal, and the United Kingdom. The new owners were required to act as a disinterested trustee over the region, promoting the welfare of its inhabitants in a variety of ways until they were able to govern themselves. The left and right banks of the Rhine were to be permanently demilitarised. The industrially important Saarland was to be governed by the League of Nations for 15 years and its coalfields administered by France. At the end of that time a plebiscite was to determine the Saar's future status. To ensure execution of the treaty's terms, Allied troops would occupy the left (German) bank of the Rhine for a period of 5–15 years. The German army was to be limited to 100,000 officers and men; the general staff was to be dissolved; vast quantities of war material were to be handed over and the manufacture of munitions rigidly curtailed. The navy was to be similarly reduced, and no military aircraft were allowed. Germany was also required to pay reparations for all civilian damage caused during the war.

The humiliating peace terms in the Treaty of Versailles provoked bitter indignation throughout Germany, and seriously weakened the new democratic regime. The greatest enemies of democracy had already been constituted. In December 1918, the Communist Party of Germany (KPD) was founded, and in 1919 it tried and failed to overthrow the new republic. Adolf Hitler in 1919 took control of the new National Socialist German Workers' Party (NSDAP), which failed in a coup in Munich in 1923. Both parties, as well as parties supporting the republic, built militant auxiliaries that engaged in increasingly violent street battles. Electoral support for both parties increased after 1929 as the Great Depression hit the economy hard, producing many unemployed men who became available for the paramilitary units. The Nazis (formerly the German Workers' Party), with a mostly rural and lower middle class base, overthrew the Weimar regime and ruled Germany in 1933–1945; the KPD, with a mostly urban and working class base, came to power (in the East) in 1945–1989.

On 11 August 1919 the Weimar constitution came into effect, with Friedrich Ebert as first President.

On 30 December 1918, the Communist Party of Germany was founded by the Spartacus League, who had split from the Social Democratic Party during the war. It was headed by Rosa Luxemburg and Karl Liebknecht, and rejected the parliamentary system. In 1920, about 300,000 members from the Independent Social Democratic Party of Germany joined the party, transforming it into a mass organization. The Communist Party had a following of about 10% of the electorate.

In the first months of 1920, the Reichswehr was to be reduced to 100,000 men, in accordance with the Treaty of Versailles. This included the dissolution of many Freikorps – units made up of volunteers. In an attempt at a coup d'état in March 1920, the Kapp Putsch, extreme right-wing politician Wolfgang Kapp let Freikorps soldiers march on Berlin and proclaimed himself Chancellor of the Reich. After four days the coup d'état collapsed, due to popular opposition and lack of support by the civil servants and the officers. Other cities were shaken by strikes and rebellions, which were bloodily suppressed.

Germany was the first state to establish diplomatic relations with the new Soviet Union. Under the Treaty of Rapallo, Germany accorded the Soviet Union "de jure" recognition, and the two signatories mutually cancelled all pre-war debts and renounced war claims.

When Germany defaulted on its reparation payments, French and Belgian troops occupied the heavily industrialised Ruhr district (January 1923). The German government encouraged the population of the Ruhr to passive resistance: shops would not sell goods to the foreign soldiers, coal-miners would not dig for the foreign troops, trams in which members of the occupation army had taken seat would be left abandoned in the middle of the street. The passive resistance proved effective, insofar as the occupation became a loss-making deal for the French government. But the Ruhr fight also led to hyperinflation, and many who lost all their fortune would become bitter enemies of the Weimar Republic, and voters of the anti-democratic right. See 1920s German inflation.

In September 1923, the deteriorating economic conditions led Chancellor Gustav Stresemann to call an end to the passive resistance in the Ruhr. In November, his government introduced a new currency, the Rentenmark (later: Reichsmark), together with other measures to stop the hyperinflation. In the following six years the economic situation improved. In 1928, Germany's industrial production even regained the pre-war levels of 1913.

The national elections of 1924 led to a swing to the right. Field Marshal Paul von Hindenburg was elected President in 1925.

In October 1925 the Treaty of Locarno was signed by Germany, France, Belgium, Britain and Italy; it recognised Germany's borders with France and Belgium. Moreover, Britain, Italy and Belgium undertook to assist France in the case that German troops marched into the demilitarised Rheinland. Locarno paved the way for Germany's admission to the League of Nations in 1926.

The actual amount of reparations that Germany was obliged to pay out was not the 132 billion marks decided in the London Schedule of 1921 but rather the 50 million marks stipulated in the A and B Bonds. Historian Sally Marks says the 112 billion marks in "C bonds" were entirely chimerical—a device to fool the public into thinking Germany would pay much more. The actual total payout from 1920 to 1931 (when payments were suspended indefinitely) was 20 billion German gold marks, worth about $5 billion US dollars or £1 billion British pounds. 12.5 billion was cash that came mostly from loans from New York bankers. The rest was goods like coal and chemicals, or from assets like railway equipment. The reparations bill was fixed in 1921 on the basis of a German capacity to pay, not on the basis of Allied claims. The highly publicized rhetoric of 1919 about paying for all the damages and all the veterans' benefits was irrelevant for the total, but it did determine how the recipients spent their share. Germany owed reparations chiefly to France, Britain, Italy and Belgium; the US received $100 million.

The Wall Street Crash of 1929 marked the beginning of the worldwide Great Depression, which hit Germany as hard as any nation. In July 1931, the "Darmstätter und Nationalbank" – one of the biggest German banks – failed. In early 1932, the number of unemployed had soared to more than 6,000,000.

On top of the collapsing economy came a political crisis: the political parties represented in the "Reichstag" were unable to build a governing majority in the face of escalating extremism from the far right (the Nazis, NSDAP) and the far left (the Communists, KPD). In March 1930, President Hindenburg appointed Heinrich Brüning Chancellor, invoking article 48 of Weimar's constitution, which allowed him to override the Parliament. To push through his package of austerity measures against a majority of Social Democrats, Communists and the NSDAP (Nazis), Brüning made use of emergency decrees and dissolved Parliament. In March and April 1932, Hindenburg was re-elected in the German presidential election of 1932.

The Nazi Party was the largest party in the national elections of 1932. On 31 July 1932 it received 37.3% of the votes, and in the election on 6 November 1932 it received less, but still the largest share, 33.1%, making it the biggest party in the "Reichstag". The Communist KPD came third, with 15%. Together, the anti-democratic parties of far right and far left were now able to hold the majority of seats in Parliament, but they were at sword's point with each other, fighting it out in the streets. The Nazis were particularly successful among Protestants, among unemployed young voters, among the lower middle class in the cities and among the rural population. It was weakest in Catholic areas and in large cities. On 30 January 1933, pressured by former Chancellor Franz von Papen and other conservatives, President Hindenburg appointed Hitler as Chancellor.

The Weimar years saw a flowering of German science and high culture, before the Nazi regime resulted in a decline in the scientific and cultural life in Germany and forced many renowned scientists and writers to flee.
German recipients dominated the Nobel prizes in science. Germany dominated the world of physics before 1933, led by Hermann von Helmholtz, Joseph von Fraunhofer, Daniel Gabriel Fahrenheit, Wilhelm Conrad Röntgen, Albert Einstein, Max Planck and Werner Heisenberg. Chemistry likewise was dominated by German professors and researchers at the great chemical companies such as BASF and Bayer and persons like Fritz Haber. Theoretical mathematicians included Carl Friedrich Gauss in the 19th century and David Hilbert in the 20th century. Karl Benz, the inventor of the automobile, was one of the pivotal figures of engineering.

Among the most important German writers were Thomas Mann (1875–1955), Hermann Hesse (1877–1962) and Bertolt Brecht (1898–1956). The pessimistic historian Oswald Spengler wrote "The Decline of the West" (1918–23) on the inevitable decay of Western Civilization, and influenced intellectuals in Germany such as Martin Heidegger, Max Scheler, and the Frankfurt School, as well as intellectuals around the world.

After 1933, Nazi proponents of "Aryan physics," led by the Nobel Prize-winners Johannes Stark and Philipp Lenard, attacked Einstein's theory of relativity as a degenerate example of Jewish materialism in the realm of science. Many scientists and humanists emigrated; Einstein moved permanently to the U.S. but some of the others returned after 1945.

The Nazi regime restored economic prosperity and ended mass unemployment using heavy spending on the military, while suppressing labor unions and strikes. The return of prosperity gave the Nazi Party enormous popularity, with only minor, isolated and subsequently unsuccessful cases of resistance among the German population over the 12 years of rule. The Gestapo (secret police) under Heinrich Himmler destroyed the political opposition and persecuted the Jews, trying to force them into exile, while taking their property. The Party took control of the courts, local government, and all civic organizations except the Protestant and Catholic churches. All expressions of public opinion were controlled by Hitler's propaganda minister, Joseph Goebbels, who made effective use of film, mass rallies, and Hitler's hypnotic speaking. The Nazi state idolized Hitler as its Führer (leader), putting all powers in his hands. Nazi propaganda centered on Hitler and was quite effective in creating what historians called the "Hitler Myth"—that Hitler was all-wise and that any mistakes or failures by others would be corrected when brought to his attention. In fact Hitler had a narrow range of interests and decision making was diffused among overlapping, feuding power centers; on some issues he was passive, simply assenting to pressures from whoever had his ear. All top officials reported to Hitler and followed his basic policies, but they had considerable autonomy on a daily basis.

In order to secure a majority for his Nazi Party in the "Reichstag", Hitler called for new elections. On the evening of 27 February 1933, the "Reichstag" building was set afire. Hitler swiftly blamed an alleged Communist uprising, and convinced President Hindenburg to sign the Reichstag Fire Decree, which rescinded most German civil liberties, including rights of assembly and freedom of the press. The decree allowed the police to detain people indefinitely without charges or a court order. Four thousand members of the Communist Party of Germany were arrested. Communist agitation was banned, but at this time not the Communist Party itself. Communists and Socialists were brought into hastily prepared Nazi concentration camps such as Kemna concentration camp, where they were at the mercy of the Gestapo, the newly established secret police force. Communist "Reichstag" deputies were taken into protective custody (despite their constitutional privileges).
Despite the terror and unprecedented propaganda, the last free General Elections of 5 March 1933, while resulting in 43.9% failed to gave the majority for the NSDAP as Hitler had hoped. Together with the German National People's Party (DNVP), however, he was able to form a slim majority government. In March 1933, the Enabling Act, an amendment to the Weimar Constitution, passed in the Reichstag by a vote of 444 to 94. To obtain the two-thirds majority needed to pass the bill, accommodations were made to the Catholic Centre Party, and the Nazis used the provisions of the Reichstag Fire Decree to keep several Social Democratic deputies from attending, and the Communists deputies had already been banned. This amendment allowed Hitler and his cabinet to pass laws—even laws that violated the constitution—without the consent of the president or the Reichstag. The Enabling Act formed the basis for the dictatorship, dissolution of the Länder; the trade unions and all political parties other than the Nazi Party were suppressed. A centralised totalitarian state was established, no longer based on the liberal Weimar constitution. Germany left the League of Nations. The coalition parliament was rigged by defining the absence of arrested and murdered deputies as voluntary and therefore cause for their exclusion as wilful absentees. Subsequently, in July the Centre Party was voluntarily dissolved in a "quid pro quo" with the Pope under the "anti-communist" Pope Pius XI for the "Reichskonkordat"; and by these manoeuvres Hitler achieved movement of these Catholic voters into the Nazi Party, and a long-awaited international diplomatic acceptance of his regime. According to Professor Dick Geary the Nazis gained a larger share of their vote in Protestant areas than in Catholic areas, in the elections held between 1928 and November 1932. The Communist Party was proscribed in April 1933.

Thereafter, the Chief of Staff of the SA, Ernst Röhm, demanded more political and military power for he and his men, which caused anxiety among military, industrial, and political leaders. In response, Hitler used the SS and Gestapo to purge the entire SA leadership—along with a number of Hitler's political adversaries (such as Gregor Strasser and former chancellor Kurt von Schleicher). It became known as the Night of the Long Knives and took place from 30 June to 2 July 1934. As a reward, the SS became an independent organisation under the command of the "Reichsführer-SS" Heinrich Himmler. He would rise to become Chief of German Police in June 1936 and already had control over the concentration camps system. Upon Hindenburg's death on 2 August 1934, Hitler's cabinet passed a law proclaiming the presidency to be vacant and transferred the role and powers of the head of state to Hitler as Chancellor and Führer (Leader).

The Nazi regime was particularly hostile towards Jews, who became the target of unending antisemitic propaganda attacks. The Nazis attempted to convince the German people to view and treat Jews as "subhumans" and immediately after winning almost 44% of parliamentary seats in the 1933 federal elections the Nazis imposed a nationwide boycott of Jewish businesses. In March 1933 the first official Nazi concentration camp was established at Dachau in Bavaria and from 1933 to 1935 the Nazi regime consolidated their power. The Law for the Restoration of the Professional Civil Service passed on 7 April 1933, which forced all Jewish civil servants to retire from the legal profession and civil service. The Nuremberg Laws of 1935 ban sexual relations between Jews and Germans and only those of German or related blood were eligible to be considered citizens; the remainder were classed as state subjects, without citizenship rights. This stripped Jews, Roma and others of their legal rights. Jews continued to suffer persecution under the Nazi regime, exemplified by the Kristallnacht pogrom of 1938, and about half of Germany's 500,000 Jews fled the country before 1939, after which escape became almost impossible.

In 1941, the Nazi leadership decided to implement a plan that they called the "Final Solution" which came to be known as the Holocaust. Under the plan, Jews and other "lesser races" along with political opponents from Germany as well as occupied countries were systematically murdered at murder sites, German concentration camps, and starting in 1942, at extermination camps. Between 1941 and 1945 Jews, Gypsies, Slavs, communists, homosexuals, the mentally and physically disabled and members of other groups were targeted and methodically murdered — the origin of the word "genocide". In total approximately 11 million people were killed during the Holocaust including 1.1 million children.

In 1935, Hitler officially re-established the Luftwaffe (air force) and reintroduced universal military service. This was in breach of the Treaty of Versailles; Britain, France and Italy issued notes of protest. Hitler had the officers swear their personal allegiance to him. In 1936 German troops marched into the demilitarised Rhineland. As the territory was part of Germany, the British and French governments did not feel that attempting to enforce the treaty was worth the risk of war. The move strengthened Hitler's standing in Germany. His reputation swelled further with the 1936 Summer Olympics, which were held in the same year in Berlin, and proved another great propaganda success for the regime as orchestrated by master propagandist Joseph Goebbels.

Historians have paid special attention to the efforts by Nazi Germany to reverse the gains women made before 1933, especially in the relatively liberal Weimar Republic. It appears the role of women in Nazi Germany changed according to circumstances. Theoretically the Nazis advocated a patriarchal society in which the German woman would recognise that her "world is her husband, her family, her children, and her home". However, before 1933, women played important roles in the Nazi organization and were allowed some autonomy to mobilize other women. After Hitler came to power in 1933, feminist groups were shut down or incorporated into the National Socialist Women's League, which coordinated groups throughout the country to promote feminine virtues, motherhood and household activities. Courses were offered on childrearing, sewing and cooking. The Nazi regime did promote a liberal code of conduct regarding heterosexual relations among Germans and was sympathetic to women who bore children out of wedlock. The "Lebensborn" (Fountain of Life) association, founded by Himmler in 1935, created a series of maternity homes where single mothers could be accommodated during their pregnancies.

As Germany prepared for war, large numbers were incorporated into the public sector and with the need for full mobilization of factories by 1943, all women under the age of fifty were required to register with the employment office for work assignments to help the war effort. Women's wages remained unequal and women were denied positions of leadership or control. In 1944–45 more than 500,000 women were volunteer uniformed auxiliaries in the German armed forces (Wehrmacht). About the same number served in civil aerial defense, 400,000 volunteered as nurses, and many more replaced drafted men in the wartime economy. In the Luftwaffe they served in auxiliary roles helping to operate the anti-aircraft systems that shot down Allied bombers.

Hitler's diplomatic strategy in the 1930s was to make seemingly reasonable demands, threatening war if they were not met. When opponents tried to appease him, he accepted the gains that were offered, then went to the next target. That aggressive strategy worked as Germany pulled out of the League of Nations (1933), rejected the Versailles Treaty and began to re-arm (1935), won back the Saar (1935), remilitarized the Rhineland (1936), formed an alliance ("axis") with Mussolini's Italy (1936), sent massive military aid to Franco in the Spanish Civil War (1936–39), annexed Austria (1938), took over Czechoslovakia after the British and French "appeasement" of the Munich Agreement of 1938, formed a peace pact with Joseph Stalin's Soviet Union in August 1939, and finally invaded Poland on 1 September 1939. Britain and France declared war on Germany two days later and World War II in Europe began.

After establishing the "Rome-Berlin axis" with Benito Mussolini, and signing the Anti-Comintern Pact with Japan – which was joined by Italy a year later in 1937 – Hitler felt able to take the offensive in foreign policy. On 12 March 1938, German troops marched into Austria, where an attempted Nazi coup had been unsuccessful in 1934. When Austrian-born Hitler entered Vienna, he was greeted by loud cheers. Four weeks later, 99% of Austrians voted in favour of the annexation (Anschluss) of their country Austria to the German Reich. After Austria, Hitler turned to Czechoslovakia, where the 3.5 million-strong Sudeten German minority was demanding equal rights and self-government. At the Munich Conference of September 1938, Hitler, the Italian leader Benito Mussolini, British Prime Minister Neville Chamberlain and French Prime Minister Édouard Daladier agreed upon the cession of Sudeten territory to the German Reich by Czechoslovakia. Hitler thereupon declared that all of German Reich's territorial claims had been fulfilled. However, hardly six months after the Munich Agreement, in March 1939, Hitler used the smoldering quarrel between Slovaks and Czechs as a pretext for taking over the rest of Czechoslovakia as the Protectorate of Bohemia and Moravia. In the same month, he secured the return of Memel from Lithuania to Germany. Chamberlain was forced to acknowledge that his policy of appeasement towards Hitler had failed.

At first Germany was very successful in its military operations, including the invasions of Poland (1939), Norway (1940), the Low Countries (1940), and France in 1940. The unexpectedly swift defeat of France resulted in an upswing in Hitler's popularity and an upsurge in war fever. Hitler made peace overtures to the new British leader Winston Churchill in July 1940, but Churchill, remained dogged in his defiance. Churchill had major financial, military, and diplomatic help from President Franklin D. Roosevelt in the U.S. Hitler's emphasis on maintaining a higher living standard postponed the full mobilization of the national economy until 1942. Germany's armed forces invaded the Soviet Union in June 1941 – weeks behind schedule due to the invasion of Yugoslavia – but swept forward until they reached the gates of Moscow.
The tide began to turn in December 1941, when the invasion of the Soviet Union hit determined resistance in the Battle of Moscow and Hitler declared war on the United States in the wake of the Japanese Pearl Harbor attack. After surrender in North Africa and losing the Battle of Stalingrad in 1942–43, the Germans were forced into the defensive. By late 1944, the United States, Canada, France, and Great Britain were closing in on Germany in the West, while the Soviets were victoriously advancing in the East. Overy estimated in 2014 that in all about 353,000 civilians were killed by British and American strategic bombing of German cities, and nine million left homeless.

Nazi Germany collapsed as Berlin was taken by the Red Army in a fight to the death on the city streets. Hitler committed suicide on 30 April 1945. The final German Instrument of Surrender was signed on 8 May 1945.

By September 1945, Nazi Germany and its Axis partners (Italy and Japan) had all been defeated, chiefly by the forces of the Soviet Union, the United States, and Great Britain. Much of Europe lay in ruins, over 60 million people worldwide had been killed (most of them civilians), including approximately 6 million Jews and 5 million non-Jews in what became known as the Holocaust. World War II resulted in the destruction of Germany's political and economic infrastructure and led directly to its partition, considerable loss of territory (especially in the East), and historical legacy of guilt and shame.

As a consequence of the defeat of Nazi Germany in 1945 and the onset of the Cold War in 1947, the country was split between the two global blocs in the East and West, a period known as the division of Germany. Millions of refugees from Central and Eastern Europe moved west, most of them to West Germany. Two countries emerged: West Germany was a parliamentary democracy, a NATO member, a founding member of what since became the European Union and one of the world's largest economies and is controlled by the US, while East Germany was a totalitarian Communist dictatorship controlled by the Soviet Union that was a satellite of Moscow. With the collapse of Communism in 1989, reunion on West Germany's terms followed.

No one doubted Germany's economic and engineering prowess; the question was how long bitter memories of the war would cause Europeans to distrust Germany, and whether Germany could demonstrate it had rejected totalitarianism and militarism and embraced democracy and human rights.

The total of German war dead was 8% to 10% out of a prewar population of 69,000,000, or between 5.5 million and 7 million people. This included 4.5 million in the military, and between 1 and 2 million civilians. There was chaos as 11 million foreign workers and POWs left, while 14 million displaced refugees from the east and soldiers returned home. During the Cold War, the West German government estimated a death toll of 2.2 million civilians due to the flight and expulsion of Germans and through forced labour in the Soviet Union. This figure remained unchallenged until the 1990s, when some historians put the death toll at 500,000–600,000 confirmed deaths. In 2006 the German government reaffirmed its position that 2.0–2.5 million deaths occurred.
At the Potsdam Conference, Germany was divided into four military occupation zones by the Allies and did not regain independence until 1949. The provinces east of the Oder and Neisse rivers (the Oder-Neisse line) were transferred to Poland, Lithuania, and Russia (Kaliningrad oblast); the 6.7 million Germans living in Poland and the 2.5 million in Czechoslovakia were forced to move west, although most had already left when the war ended.

Denazification removed, imprisoned, or executed most top officials of the old regime, but most middle and lower ranks of civilian officialdom were not seriously affected. In accordance with the Allied agreement made at the Yalta conference millions of POWs were used as forced labor by the Soviet Union and other European countries.

In the East, the Soviets crushed dissent and imposed another police state, often employing ex-Nazis in the dreaded Stasi. The Soviets extracted about 23% of the East German GNP for reparations, while in the West reparations were a minor factor.

In 1945–46 housing and food conditions were bad, as the disruption of transport, markets, and finances slowed a return to normal. In the West, bombing had destroyed the fourth of the housing stock, and over 10 million refugees from the east had crowded in, most living in camps. Food production in 1946–48 was only two-thirds of the prewar level, while grain and meat shipments – which usually supplied 25% of the food – no longer arrived from the East. Furthermore, the end of the war brought the end of large shipments of food seized from occupied nations that had sustained Germany during the war. Coal production was down 60%, which had cascading negative effects on railroads, heavy industry, and heating. Industrial production fell more than half and reached prewar levels only at the end of 1949.

Allied economic policy originally was one of industrial disarmament plus building the agricultural sector. In the western sectors, most of the industrial plants had minimal bomb damage and the Allies dismantled 5% of the industrial plants for reparations.

However, deindustrialization became impractical and the U.S. instead called for a strong industrial base in Germany so it could stimulate European economic recovery. The U.S. shipped food in 1945–47 and made a $600 million loan in 1947 to rebuild German industry. By May 1946 the removal of machinery had ended, thanks to lobbying by the U.S. Army. The Truman administration finally realised that economic recovery in Europe could not go forward without the reconstruction of the German industrial base on which it had previously been dependent. Washington decided that an "orderly, prosperous Europe requires the economic contributions of a stable and productive Germany."

In 1945 the occupying powers took over all newspapers in Germany and purged them of Nazi influence. The American occupation headquarters, the Office of Military Government, United States (OMGUS) began its own newspaper based in Munich, "Die Neue Zeitung." It was edited by German and Jewish émigrés who fled to the United States before the war. Its mission was to encourage democracy by exposing Germans to how American culture operated. The paper was filled with details on American sports, politics, business, Hollywood, and fashions, as well as international affairs.

In 1949 the western half of the Soviet zone became the "Deutsche Demokratische Republik" – "DDR" ("German Democratic Republic" – "GDR", simply often "East Germany"), under control of the Socialist Unity Party. Neither country had a significant army until the 1950s, but East Germany built the Stasi into a powerful secret police that infiltrated every aspect of the society.

East Germany was an Eastern bloc state under political and military control of the Soviet Union through her occupation forces and the Warsaw Treaty. Political power was solely executed by leading members ("Politburo") of the communist-controlled Socialist Unity Party (SED). A Soviet-style command economy was set up; later the GDR became the most advanced Comecon state. While East German propaganda was based on the benefits of the GDR's social programs and the alleged constant threat of a West German invasion, many of her citizens looked to the West for political freedoms and economic prosperity.

Walter Ulbricht (1893–1973) was the party boss from 1950 to 1971. In 1933, Ulbricht had fled to Moscow, where he served as a Comintern agent loyal to Stalin. As World War II was ending, Stalin assigned him the job of designing the postwar German system that would centralize all power in the Communist Party. Ulbricht became deputy prime minister in 1949 and secretary (chief executive) of the Socialist Unity (Communist) party in 1950. Some 2.6 million people had fled East Germany by 1961 when he built the Berlin Wall to stop them — shooting those who attempted it. What the GDR called the "Anti-Fascist Protective Wall" was a major embarrassment for the program during the Cold War, but it did stabilize East Germany and postpone its collapse. Ulbricht lost power in 1971, but was kept on as a nominal head of state. He was replaced because he failed to solve growing national crises, such as the worsening economy in 1969–70, the fear of another popular uprising as had occurred in 1953, and the disgruntlement between Moscow and Berlin caused by Ulbricht's détente policies toward the West.

The transition to Erich Honecker (General Secretary from 1971 to 1989) led to a change in the direction of national policy and efforts by the Politburo to pay closer attention to the grievances of the proletariat. Honecker's plans were not successful, however, with the dissent growing among East Germany's population.

In 1989, the socialist regime collapsed after 40 years, despite its omnipresent secret police, the Stasi. Main reasons for the collapse include severe economic problems and growing emigration towards the West.

East Germany's culture was shaped by Communism and particularly Stalinism. It was characterized by East German psychoanalyst Hans-Joachim Maaz in 1990 as having produced a "Congested Feeling" among Germans in the East as a result of Communist policies criminalizing personal expression that deviates from government approved ideals, and through the enforcement of Communist principals by physical force and intellectual repression by government agencies, particularly the Stasi. Critics of the East German state have claimed that the state's commitment to communism was a hollow and cynical tool of a ruling elite. This argument has been challenged by some scholars who claim that the Party was committed to the advance of scientific knowledge, economic development, and social progress. However, the vast majority regarded the state's Communist ideals to be nothing more than a deceptive method for government control.

According to German historian Jürgen Kocka (2010):

In 1949, the three western occupation zones (American, British, and French) were combined into the Federal Republic of Germany (FRG, West Germany). The government was formed under Chancellor Konrad Adenauer and his conservative CDU/CSU coalition. The CDU/CSU was in power during most of the period since 1949. The capital was Bonn until it was moved to Berlin in 1990. In 1990 FRG absorbed East Germany and gained full sovereignty over Berlin. At all points West Germany was much larger and richer than East Germany, which became a dictatorship under the control of the Communist Party and was closely monitored by Moscow. Germany, especially Berlin, was a cockpit of the Cold War, with NATO and the Warsaw Pact assembling major military forces in west and east. However, there was never any combat.

West Germany enjoyed prolonged economic growth beginning in the early 1950s ("Wirtschaftswunder" or "Economic Miracle"). Industrial production doubled from 1950 to 1957, and gross national product grew at a rate of 9 or 10% per year, providing the engine for economic growth of all of Western Europe. Labor union supported the new policies with postponed wage increases, minimized strikes, support for technological modernization, and a policy of co-determination ("Mitbestimmung"), which involved a satisfactory grievance resolution system as well as requiring representation of workers on the boards of large corporations. The recovery was accelerated by the currency reform of June 1948, U.S. gifts of $1.4 billion as part of the Marshall Plan, the breaking down of old trade barriers and traditional practices, and the opening of the global market. West Germany gained legitimacy and respect, as it shed the horrible reputation Germany had gained under the Nazis.

West Germany played a central role in the creation of European cooperation; it joined NATO in 1955 and was a founding member of the European Economic Community in 1958.

The most dramatic and successful policy event was the currency reform of 1948. Since the 1930s, prices and wages had been controlled, but money had been plentiful. That meant that people had accumulated large paper assets, and that official prices and wages did not reflect reality, as the black market dominated the economy and more than half of all transactions were taking place unofficially. On 21 June 1948, the Western Allies withdrew the old currency and replaced it with the new Deutsche Mark at the rate of 1 new per 10 old. This wiped out 90% of government and private debt, as well as private savings. Prices were decontrolled, and labor unions agreed to accept a 15% wage increase, despite the 25% rise in prices. The result was that prices of German export products held steady, while profits and earnings from exports soared and were poured back into the economy. The currency reforms were simultaneous with the $1.4 billion in Marshall Plan money coming in from the United States, which was used primarily for investment.

In addition, the Marshall Plan forced German companies, as well as those in all of Western Europe, to modernize their business practices and take account of the international market. Marshall Plan funding helped overcome bottlenecks in the surging economy caused by remaining controls (which were removed in 1949), and Marshall Plan business reforms opened up a greatly expanded market for German exports. Overnight, consumer goods appeared in the stores, because they could be sold for realistic prices, emphasizing to Germans that their economy had turned a corner.

The success of the currency reform angered the Soviets, who cut off all road, rail, and canal links between the western zones and West Berlin. This was the Berlin Blockade, which lasted from 24 June 1948 to 12 May 1949. In response, the U.S. and Britain launched an airlift of food and coal and distributed the new currency in West Berlin as well. The city thereby became economically integrated into West Germany.

Konrad Adenauer (1876–1967) was the dominant leader in West Germany. He was the first chancellor (top official) of the FRG, 1949–63, and until his death was the founder and leader of the Christian Democratic Union (CDU), a coalition of conservatives, ordoliberals, and adherents of Protestant and Catholic social teaching that dominated West Germany politics for most of its history. During his chancellorship, the West Germany economy grew quickly, and West Germany established friendly relations with France, participated in the emerging European Union, established the country's armed forces (the "Bundeswehr"), and became a pillar of NATO as well as firm ally of the United States. Adenauer's government also commenced the long process of reconciliation with the Jews and Israel after the Holocaust.

Ludwig Erhard (1897–1977) was in charge of economic policy as economics director for the British and American occupation zones and was Adenauer's long-time economics minister. Erhard's decision to lift many price controls in 1948 (despite opposition from both the social democratic opposition and Allied authorities), plus his advocacy of free markets, helped set the Federal Republic on its strong growth from wartime devastation. Norbert Walter, a former chief economist at Deutsche Bank, argues that "Germany owes its rapid economic advance after World War II to the system of the Social Market Economy, established by Ludwig Erhard." Erhard was politically less successful when he served as the CDU Chancellor from 1963 until 1966. Erhard followed the concept of a social market economy, and was in close touch with professional economists. Erhard viewed the market itself as social and supported only a minimum of welfare legislation. However, Erhard suffered a series of decisive defeats in his effort to create a free, competitive economy in 1957; he had to compromise on such key issues as the anti-cartel legislation. Thereafter, the West German economy evolved into a conventional west European welfare state.

Meanwhile, in adopting the Godesberg Program in 1959, the Social Democratic Party of Germany (SPD) largely abandoned Marxism ideas and embraced the concept of the market economy and the welfare state. Instead it now sought to move beyond its old working class base to appeal the full spectrum of potential voters, including the middle class and professionals. Labor unions cooperated increasingly with industry, achieving labor representation on corporate boards and increases in wages and benefits.

In 1966 Erhard lost support and Kurt Kiesinger (1904–1988) was elected as Chancellor by a new CDU/CSU-SPD alliance combining the two largest parties. Socialist (SPD) leader Willy Brandt was Deputy Federal Chancellor and Foreign Minister. The Grand Coalition lasted 1966–69 and is best known for reducing tensions with the Soviet bloc nations and establishing diplomatic relations with Czechoslovakia, Romania and Yugoslavia.

With a booming economy short of unskilled workers, especially after the Berlin Wall cut off the steady flow of East Germans, the FRG negotiated migration agreements with Italy (1955), Spain (1960), Greece (1960), and Turkey (1961) that brought in hundreds of thousands of temporary guest workers, called "Gastarbeiter". In 1968 the FRG signed a guest worker agreement with Yugoslavia that employed additional guest workers. "Gastarbeiter" were young men who were paid full-scale wages and benefits, but were expected to return home in a few years.

The agreement with Turkey ended in 1973 but few workers returned because there were few good jobs in Turkey. By 2010 there were about 4 million people of Turkish descent in Germany. The generation born in Germany attended German schools, but had a poor command of either German or Turkish, and had either low-skilled jobs or were unemployed.

Willy Brandt (1913–1992) was the leader of the Social Democratic Party in 1964–87 and West German Chancellor in 1969–1974. Under his leadership, the German government sought to reduce tensions with the Soviet Union and improve relations with the German Democratic Republic, a policy known as the "Ostpolitik". Relations between the two German states had been icy at best, with propaganda barrages in each direction. The heavy outflow of talent from East Germany prompted the building of the Berlin Wall in 1961, which worsened Cold War tensions and prevented East Germans from travel. Although anxious to relieve serious hardships for divided families and to reduce friction, Brandt's "Ostpolitik" was intent on holding to its concept of "two German states in one German nation."

"Ostpolitik" was opposed by the conservative elements in Germany, but won Brandt an international reputation and the Nobel Peace Prize in 1971. In September 1973, both West and East Germany were admitted to the United Nations. The two countries exchanged permanent representatives in 1974, and, in 1987, East Germany's leader Erich Honecker paid an official state visit to West Germany.

After 1973, Germany was hard hit by a worldwide economic crisis, soaring oil prices, and stubbornly high unemployment, which jumped from 300,000 in 1973 to 1.1 million in 1975. The Ruhr region was hardest hit, as its easy-to-reach coal mines petered out, and expensive German coal was no longer competitive. Likewise the Ruhr steel industry went into sharp decline, as its prices were undercut by lower-cost suppliers such as Japan. The welfare system provided a safety net for the large number of unemployed workers, and many factories reduce their labor force and began to concentrate on high-profit specialty items. After 1990 the Ruhr moved into service industries and high technology. Cleaning up the heavy air and water pollution became a major industry in its own right. Meanwhile, formerly rural Bavaria became a high-tech center of industry.

A spy scandal forced Brandt to step down as Chancellor while remaining as party leader. He was replaced by Helmut Schmidt (b. 1918), of the SPD, who served as Chancellor in 1974–1982. Schmidt continued the "Ostpolitik" with less enthusiasm. He had a PhD in economics and was more interested in domestic issues, such as reducing inflation. The debt grew rapidly as he borrowed to cover the cost of the ever more expensive welfare state. After 1979, foreign policy issues grew central as the Cold War turned hot again. The German peace movement mobilized hundreds of thousands of demonstrators to protest against American deployment in Europe of new medium-range ballistic missiles. Schmidt supported the deployment but was opposed by the left wing of the SPD and by Brandt.

The pro-business Free Democratic Party (FDP) had been in coalition with the SPD, but now it changed direction. Led by Finance Minister Otto Graf Lambsdorff (1926–2009) the FDP adopted the market-oriented "Kiel Theses" in 1977; it rejected the Keynesian emphasis on consumer demand, and proposed to reduce social welfare spending, and try to introduce policies to stimulate production and facilitate jobs. Lambsdorff argued that the result would be economic growth, which would itself solve both the social problems and the financial problems. As a consequence, the FDP switched allegiance to the CDU and Schmidt lost his parliamentary majority in 1982. For the only time in West Germany's history, the government fell on a vote of no confidence.

Helmut Kohl (1930–2017) brought the conservatives back to power with a CDU/CSU-FDP coalition in 1982, and served as Chancellor until 1998. After repeated victories in 1983, 1987, 1990 and 1994 he was finally defeated by a landslide that was the biggest on record, for the left in the 1998 federal elections, and was succeeded as Chancellor by Gerhard Schröder of the SPD. Kohl is best known for orchestrating reunification with the approval of all the Four Powers from World War II, who still had a voice in German affairs.

During the summer of 1989, rapid changes known as "peaceful revolution" or "Die Wende" took place in East Germany, which quickly led to German reunification. Growing numbers of East Germans emigrated to West Germany, many via Hungary after Hungary's reformist government opened its borders. Thousands of East Germans also tried to reach the West by staging sit-ins at West German diplomatic facilities in other East European capitals, most notably in Prague. The exodus generated demands within East Germany for political change, and mass demonstrations in several cities continued to grow.

Unable to stop the growing civil unrest, Erich Honecker was forced to resign in October, and on 9 November, East German authorities unexpectedly allowed East German citizens to enter West Berlin and West Germany. Hundreds of thousands of people took advantage of the opportunity; new crossing points were opened in the Berlin Wall and along the border with West Germany. This led to the acceleration of the process of reforms in East Germany that ended with the German reunification that came into force on 3 October 1990.

The SPD in coalition with the Greens won the elections of 1998. SPD leader Gerhard Schröder positioned himself as a centrist "Third Way" candidate in the mold of Britain's Tony Blair and America's Bill Clinton.

Schröder, in March 2003, reversed his position and proposed a significant downsizing of the welfare state, known as Agenda 2010. He had enough support to overcome opposition from the trade unions and the SPD's left wing. Agenda 2010 had five goals: tax cuts; labor market deregulation, especially relaxing rules protecting workers from dismissal and setting up Hartz concept job training; modernizing the welfare state by reducing entitlements; decreasing bureaucratic obstacles for small businesses; and providing new low-interest loans to local governments.

From 2005 to 2009, Germany was ruled by a grand coalition led by the CDU's Angela Merkel as chancellor. Since the 2009 elections, Merkel has headed a centre-right government of the CDU/CSU and FDP.

Together with France and other EU states, Germany has played the leading role in the European Union. Germany (especially under Chancellor Helmut Kohl) was one of the main supporters of admitting many East European countries to the EU. Germany is at the forefront of European states seeking to exploit the momentum of monetary union to advance the creation of a more unified and capable European political, defence and security apparatus. German Chancellor Schröder expressed an interest in a permanent seat for Germany in the UN Security Council, identifying France, Russia, and Japan as countries that explicitly backed Germany's bid. Germany formally adopted the Euro on 1 January 1999 after permanently fixing the Deutsche Mark rate on 21 December 1998.

Since 1990, the German Bundeswehr has participated in a number of peacekeeping and disaster relief operations abroad. Since 2002, German troops formed part of the International Security Assistance Force in the war in Afghanistan, resulting in the first German casualties in combat missions since World War II.

In the worldwide economic recession that began in 2008, Germany did relatively well. However, the economic instability of Greece and several other EU nations in 2010–11 forced Germany to reluctantly sponsor a massive financial rescue.

In the wake of the disaster to the nuclear industry in Japan following its 2011 earthquake and tsunami, German public opinion turned sharply against nuclear power in Germany, which produces a fourth of the electricity supply. In response Merkel has announced plans to close down the nuclear system over the next decade, and to rely even more heavily on wind and other alternative energy sources, in addition to coal and natural gas. For further information, see Germany in 2011.

Germany was affected by the European migrant crisis in 2015 as it became the final destination of choice for many asylum seekers from Africa and the Middle East entering the EU. The country took in over a million refugees and migrants and developed a quota system which redistributed migrants around its federal states based on their tax income and existing population density. The decision by Merkel to authorize unrestricted entry led to heavy criticism in Germany as well as within Europe.

A major historiographical debate about the German history concerns the "Sonderweg", the alleged "special path" that separated German history from the normal course of historical development, and whether or not Nazi Germany was the inevitable result of the "Sonderweg". Proponents of the "Sonderweg" theory such as Fritz Fischer point to such events of the Revolution of 1848, the authoritarianism of the Second Empire and the continuation of the Imperial elite into the Weimar and Nazi periods. Opponents such as Gerhard Ritter of the "Sonderweg" theory argue that proponents of the theory are guilty of seeking selective examples, and there was much contingency and chance in German history. In addition, there was much debate within the supporters of the "Sonderweg" concept as for the reasons for the "Sonderweg", and whether or not the "Sonderweg" ended in 1945. Was there a Sonderweg? Winkler says:

Theodor Heuss (; 31 January 1884 – 12 December 1963) was a West German liberal politician who served as the first President of the Federal Republic of Germany from 1949 to 1959. Beside the stern chancellor Konrad Adenauer, Heuss' cordial manners largely contributed to the stabilization of democracy in West Germany during the "Wirtschaftswunder" years.

Theodor Heuss

Heuss was born in Brackenheim, a small town in Württemberg near Heilbronn. This “wine community” is located next to the border of Swabian to the Franconian area. He studied economics, art history and political science at the universities of Munich and Berlin, receiving his doctorate in 1905 in Munich with Lujo Brentano as his thesis adviser. On 11 April 1908, he married Elly Heuss-Knapp (1881–1952), with whom he had a son. The minister at the Lutheran wedding ceremony held in Straßburg was Albert Schweitzer, a close friend of Elly's.
Heuss was a member of the Evangelical Church in Germany.
After his studies Heuss worked as a political journalist in Berlin and from 1905 until 1912 presided over the magazine "Die Hilfe" ("The Aid") published by Friedrich Naumann. From 1912 to 1918, he was editor in chief of the "Neckarzeitung" (Neckar Newspaper) in Heilbronn. In Berlin, he worked as editor for the weekly newsletter "Deutsche Politik" ("German Politics"). With Naumann, Heuss in 1903 he joined the liberal Free-minded Union, which in 1910 merged in the Progressive People's Party ("Fortschrittliche Volkspartei"), in which he was engaged until its dissolution in 1918.

After World War I, Heuss between 1923 and 1926 published the magazine "Die Deutsche Nation" ("The German Nation"). He had become a member of the German Democratic Party ("Deutsche Demokratische Partei", DDP), from 1930 renamed German State Party ("Deutsche Staatspartei", DStP), the political heir of the Fortschrittliche Volkspartei in 1918 and was a member of the Reichstag parliament from 1924 to 1928 and again from 1930 to 1933.

On 23 March 1933, along with his four fellow DStP parliamentarians, Heuss voted in favour of the Enabling Act (Ermächtigungsgesetz), granting Chancellor Adolf Hitler quasi-dictatorial powers. He had set out to abstain, but after Heinrich Brüning indicated that with regard to the "Reichskonkordat" the Centre Party MPs would assent, ultimately subordinated to party discipline. Alternative views of Hermann Dietrich, Weimar Republic finance minister claim that he was part of the majority in favor of voting for the enabling law. When Germany became a one-party state, the DStP was dissolved on 28 June 1933 and Heuss was divested of his Reichstag mandate by decree of Minister of the Interior Wilhelm Frick with effect from 8 July.

Following the end of his term he returned to private life. During the Third Reich he stayed in contact with a network of liberals, leading to contacts with the German resistance towards the end of the war, though he was not an active resister. In 1936 Heuss faced a publication ban, nevertheless in 1941 he became an employee of the "Frankfurter Zeitung", one of the few remaining liberal newspapers at that time. Heuss wrote under pseudonyms until publishing of the paper was finally prohibited in 1943. He spent the following years writing a biography of Robert Bosch.

After World War II the US Office of Military Government on 24 September 1945 appointed Heuss the first Minister of Education and Cultural Affairs in the German state of Württemberg-Baden under his fellow party member Minister-president Reinhold Maier, in favour of whom he resigned in 1946. As a co-founder of the Democratic People's Party ("Demokratische Volkspartei", DVP), the predecessor of the German Free Democratic Party ("Freie Demokratische Partei", FDP) in the southwestern German states, he was a member of the Württemberg-Baden state parliament ("Landtag") from 1946 to 1949. Heuss also taught history at the Stuttgart Institute of Technology in 1946 and 1947, receiving the title of an honorary professor in 1948.

After plans elaborated with Wilhelm Külz to build up an all-German liberal party had failed, Heuss in December 1948 was elected head of West German and Berlin sections of the newly founded Free Democratic Party. He advocated uniting all liberal parties in the Western occupation zones, overcoming the split between right liberals and left liberals that had existed in the Weimar Republic. In 1948, he was a member of the Parlamentarischer Rat (Parliamentary Council) at Bonn with considerable influence in the drafting of West Germany's constitution, the Basic Law for the Federal Republic of Germany.

After being elected to the first German Bundestag, he relinquished his parliamentary mandate on 12 September 1949, when he was elected President by the Federal Convention ("Bundesversammlung") defeating the Social Democrat leader Kurt Schumacher in the second ballot. He took the oath required by article 56 of the Basic Law before a joint session of the Bundestag and the Bundesrat on the same date. By the time he was confirmed as the first democratic German president since Paul von Hindenburg, he refused to be called “Excellency”, preferring instead to be called simply “Herr Heuss”, "Herr Bundespräsident" is the German term of address up to today. Heuss's plans for a new national anthem were aborted by Adenauer, who – in rare accordance with Kurt Schumacher – had the third stanza of the old "Deutschlandlied" established in 1952.

A widower since 1952, Heuss was re-elected in 1954 with practically no opposition, after the Social Democrats had renounced the nomination of a rival candidate. Not until May 1956, could he make his first state visit, invited by King Paul of Greece. The president, accompanied by Foreign Minister Heinrich von Brentano, was overwhelmed by the warm reception in Athens, considering that the country had heavily suffered under German occupation in World War II. He held office until the end of his term on 12 September 1959, succeeded by Heinrich Lübke. He had declined a third term in office, as this would have necessitated changing the constitution.

Heuss shaped the office of president by his non-partisan governing. As a representative of the democratic-liberal and cultural traditions of Germany, he was a symbol of confidence in the German post-war republic in the international community. His further state visits to Turkey, Italy, Canada, the United States, and the United Kingdom contributed greatly to the increase of appreciation toward the still young Federal Republic of Germany. He was opposed to re-armament and the founding of the new West German Army in 1955, but had no power to stop it. His ironic speech at the swearing in of the first new soldiers, ""Nun siegt mal schön!"" ("Happy war-winning!"), is well remembered. In 1959, Heuss was awarded the prestigious Peace Prize of the German Book Trade ("Friedenspreis des Deutschen Buchhandels'.')

On 12 December 1963 Heuss died in Stuttgart, aged 79.

Since 1964, the Theodor Heuss Prize has been awarded for exemplary democratic disposition. Heuss's former residence is now open to the public as the "Theodor-Heuss-Haus". His image appeared on one series of the two-mark coin and numerous streets and squares all over Germany have been named in his honour. During his time in office, his image also appeared on definitive stamps in West Germany issued between 1954 and 1960. An Airbus A310 aircraft of the Luftwaffe used by the German head of government also carries his name.

The foundation for the influential position held by Germany today was laid during the (economic miracle) of the 1950s when West Germany rose from the enormous destruction wrought by World War II to become the world's third-largest economy. The first chancellor Konrad Adenauer, who remained in office until 1963, had worked for a full alignment with NATO rather than neutrality. He not only secured a membership in NATO but was also a proponent of agreements that developed into the present-day European Union. When the G6 was established in 1975, there was no question whether the Federal Republic of Germany would be a member as well.

West Germany

West Germany is the common English name for the Federal Republic of Germany () in the period between its creation on 23 May 1949 and German reunification on 3 October 1990. During this Cold War era, NATO-aligned West Germany and Warsaw Pact-aligned East Germany were divided by the Inner German border. After 1961 West Berlin was physically separated from East Berlin as well as from East Germany by the Berlin Wall. This situation ended when East Germany was dissolved and split into five states, which then joined the ten states of the Federal Republic of Germany along with the reunified city-state of Berlin. With the reunification of West and East Germany, the Federal Republic of Germany, enlarged now to sixteen states, became known simply as "Germany". This period is referred to as the Bonn Republic ("Bonner Republik") by historians, alluding to the interwar Weimar Republic and the post-reunification Berlin Republic.

The Federal Republic of Germany was established from eleven states formed in the three Allied Zones of occupation held by the United States, the United Kingdom and France (the "Western Zones"). US and British forces remained in the country throughout the Cold War. Its population grew from roughly 51 million in 1950 to more than 63 million in 1990. The city of Bonn was its (provisional) capital. The fourth Allied occupation zone (the East Zone, or ) was held by the Soviet Union, bounded to the east by the Oder-Neisse line; and in 1949 this became the socialist German Democratic Republic (abbreviated GDR; in German or ) with its capital in East Berlin. The former parts of Germany east of the Oder-Neisse were separated from 'Germany as a whole' by the Potsdam Agreement of 1945, and then annexed by Poland and the Soviet Union. As a result, West Germany had a territory about half the size of the interwar period democratic Weimar Republic.

At the onset of the Cold War, Europe was divided among the Western and Eastern blocs. Germany was divided into two countries and two special territories, the Saarland and divided Berlin. Initially the Federal Republic of Germany claimed an exclusive mandate for all of Germany, considering itself to be the democratically reorganised continuation of the 1871–1945 German Reich. It took the line that the GDR was an illegally constituted puppet state. Though the GDR did hold regular elections, these were not free and fair. From the West German perspective, the GDR was therefore illegitimate.

Three southwestern states of West Germany merged to form Baden-Württemberg in 1952, and the Saarland joined the Federal Republic of Germany in 1957. In addition to the resulting ten states, West Berlin was considered an unofficial 11th state. While legally not part of the Federal Republic of Germany, as Berlin was under the control of the Allied Control Council, West Berlin aligned itself politically with West Germany and was directly or indirectly represented in its federal institutions.

Relations with the Soviet bloc improved during the era of "" around 1970, West Germany then adopting the principle that the GDR and the Federal Republic were "two German states within one German nation". Claims to an exclusive mandate were formally relinquished, West Germany accepting that, within its own boundaries, the GDR represented its population as a German state outside the Federal Republic. In addition, although the Federal Republic still did not recognise the GDR as being fully a sovereign state in international law, it nevertheless accepted that within the forum of international law East Germany was an independent sovereign state with which the Federal Republic could enter into binding international agreements. But in respect of legality within its own boundaries, West Germany continued to maintain that there remained a single (but dormant) overall German nation, that could only be represented by the Federal Republic. From 1973 onward, East Germany maintained the existence of two German sovereign states, with West Germany being both and a foreign country. The Federal Republic and the GDR agreed that neither of them could speak in the name of the other.

Following the collapse of communism in Central and Eastern Europe in 1989, symbolised by the opening of the Berlin Wall, there was a rapid move towards German reunification. East Germany voted to dissolve itself and accede to the Federal Republic in 1990. Its five post-war states () were reconstituted along with the reunited Berlin, which ended its special status and formed an additional. They formally joined the Federal Republic on 3 October 1990, raising the number of states from 10 to 16, ending the division of Germany. The expanded Federal Republic retained West Germany's political culture and continued its existing memberships in international organisations, as well as its Western foreign policy alignment and affiliation to Western alliances like UN, NATO, OECD and the European Union.

The official name of West Germany, adopted in 1949 and unchanged since is (Federal Republic of Germany).

In East Germany, the terms (West Germany) or (West German Federal Republic) were preferred during the 1950s and 1960s. This changed once under its 1968 constitution, when the idea of a single German nation was abandoned by East Germany, and as a result West Germans and West Berliners were officially considered foreigners. In the early 1970s, starting in the East German, the initialism "BRD" (FRG) for the "Federal Republic of Germany" began to prevail in East German usage. In 1973, official East German sources adopted it as a standard expression and other Eastern Bloc nations soon followed suit.

In reaction to this move, in 1965 the West German Federal Minister of All-German Affairs Erich Mende issued the "Directives for the appellation of Germany", recommending avoiding the initialism. On 31 May 1974, the heads of West German federal and state governments recommended always using the full name in official publications. From then on West German sources avoided the abbreviated form, with the exception of left-leaning organizations which embraced it. In November 1979 the federal government informed the that the West German public broadcasters and had agreed to refuse to use the initialism.

The ISO 3166-1 alpha-2 country code of West Germany was "DE" (for "Deutschland", Germany), which has remained the country code of Germany after reunification. ISO 3166-1 alpha-2 are the most widely used country codes, and the "DE" code is notably used as country identifier extending the postal code and as the Internet's country code top-level domain.de. Accordingly the less widely used ISO 3166-1 alpha-3 country code of West Germany was "DEU", which has also remained the country code of reunified Germany. The now deleted codes for East Germany, on the other hand, was "DD" in ISO 3166-1 alpha-2 and "DDR" in ISO 3166-1 alpha-3.

The colloquial term "West Germany" or its equivalent was used in many languages. "" was also a widespread colloquial form used in German-speaking countries, usually without political overtones.

On 4–11 February 1945 leaders from the United States, the United Kingdom and the Soviet Union held the Yalta Conference where future arrangements as regards post-war Europe and strategy against Japan in the Pacific were negotiated. The conference agreed that post-war Germany would be divided into four occupation zones: a French Zone in the far west; a British Zone in the northwest; an American Zone in the south; and a Soviet Zone in the East. Berlin was separately divided into four zones. These divisions were not intended to dismember Germany, only to designate zones of administration.

By the subsequent Potsdam Agreement, the four Allied Powers asserted joint sovereignty over 'Germany as a whole', defined as the totality of the territory within the occupation zones. Former German areas east of the rivers Oder and Neisse and outside of 'Germany as a whole' were separated from German sovereignty and transferred to Polish and Russian administration, their Polish and Russian status to be confirmed at a final Peace Treaty. Following wartime commitments by the Allies to the governments-in-exile of Czechoslovakia and Poland, the Potsdam Protocols also agreed to the 'orderly and humane' transfer back to Germany as a whole of the ethnic German populations in Poland, Czechoslovakia and Hungary. Eight million German expellees and refugees eventually settled in West Germany. Between 1946 and 1949, three of the occupation zones began to merge. First, the British and American zones were combined into the quasi-state of Bizonia. Soon afterwards, the French zone was included into Trizonia. At the same time, new federal states () were formed in the Allied zones; replacing the geography of pre-Nazi German states such as the Free State of Prussia and the Republic of Baden, which had derived ultimately from former independent German kingdoms and principalities.

In 1949 with the continuation and aggravation of the Cold War (witness the Berlin Airlift of 1948–49), the two German states that were originated in the Western Allied and the Soviet Zones became known internationally as West Germany and East Germany. Commonly known in English as East Germany, the former Soviet Occupation Zone, eventually became the "German Democratic Republic" or "GDR". In 1990 West Germany and East Germany jointly signed the Treaty on the Final Settlement With Respect to Germany; by which transitional status of Germany following World War II was definitively ended, the Four Allied powers relinquished their joint residual sovereign authority for Germany as a whole, the two parts of Germany confirmed their post-war external boundaries as final and irreversible (including the 1945 transfer of former German lands east of the Oder-Neisse line), and the Allied Powers confirmed their consent to German Reunification. From 3 October 1990, after the reformation of the GDR's, the East German states joined the Federal Republic.

With territories and frontiers that coincided largely with the ones of old Medieval East Francia and the 19th-century Napoleonic Confederation of the Rhine, the Federal Republic of Germany, founded on 23 May 1949, under the terms of the Bonn–Paris conventions it obtained "the full authority of a sovereign state" on 5 May 1955 (although "full sovereignty" was not obtained until the Two Plus Four Agreement in 1990). The former occupying Western troops remained on the ground, now as part of the North Atlantic Treaty Organization (NATO), which West Germany joined on 9 May 1955, promising to rearm itself soon.

West Germany became a focus of the Cold War with its juxtaposition to East Germany, a member of the subsequently founded Warsaw Pact. The former capital, Berlin, had been divided into four sectors, with the Western Allies joining their sectors to form West Berlin, while the Soviets held East Berlin. West Berlin was completely surrounded by East German territory and had suffered a Soviet blockade in 1948–49, which was overcome by the Berlin airlift.
The outbreak of the Korean War in June 1950 led to U.S. calls to rearm West Germany to help defend Western Europe from the perceived Soviet threat. Germany's partners in the Coal and Steel Community proposed to establish a European Defence Community (EDC), with an integrated army, navy and air force, composed of the armed forces of its member states. The West German military would be subject to complete EDC control, but the other EDC member states (Belgium, France, Italy, Luxembourg and the Netherlands) would cooperate in the EDC while maintaining independent control of their own armed forces.

Though the EDC treaty was signed (May 1952), it never entered into force. France's Gaullists rejected it on the grounds that it threatened national sovereignty, and when the French National Assembly refused to ratify it (August 1954), the treaty died. The French Gaullists and communists had killed the French government's proposal. Then other means had to be found to allow West German rearmament. In response, at the London and Paris Conferences, the Brussels Treaty was modified to include West Germany, and to form the Western European Union (WEU). West Germany was to be permitted to rearm (an idea many Germans rejected), and have full sovereign control of its military, called the. The WEU, however, would regulate the size of the armed forces permitted to each of its member states. Also, the German constitution prohibited any military action, except in the case of an external attack against Germany or its allies (). Also, Germans could reject military service on grounds of conscience, and serve for civil purposes instead.

The three Western Allies retained occupation powers in Berlin and certain responsibilities for Germany as a whole. Under the new arrangements, the Allies stationed troops within West Germany for NATO defense, pursuant to stationing and status-of-forces agreements. With the exception of 55,000 French troops, Allied forces were under NATO's joint defense command. (France withdrew from the collective military command structure of NATO in 1966.)

Konrad Adenauer was 73 years old when he became chancellor, and for this reason he was initially reckoned as a caretaker. However, he stayed in power for 14 years. The grand old man of German postwar politics had to be dragged—almost literally—out of office in 1963. In 1959 it was time to elect a new President and Adenauer decided that he would nominate Erhard, the architect of the economic miracle. Erhard was not enthusiastic, and to everybody's surprise, Adenauer decided at the age of 83 that he would take on the position. He apparently believed that this would allow him to dominate the scene for up to ten more years in spite of the growing mood for change. However, when his advisers informed him that the powers of the president were almost entirely ceremonial, he quickly lost interest. An alternative candidate was needed and eventually the Minister of Agriculture, Heinrich Lübke took on the task and was duly elected.
In October 1962 the weekly news magazine published an analysis of the West German military defence. The conclusion was that there were several weaknesses in the system. Ten days after publication, the offices of in Hamburg were raided by the police and quantities of documents were seized. Chancellor Adenauer proclaimed in the that the article was tantamount to high treason and that the authors would be prosecuted. The editor/owner of the magazine, Rudolf Augstein spent some time in jail before the public outcry over the breaking of laws on freedom of the press became too loud to be ignored. The FDP members of Adenauer's cabinet resigned from the government, demanding the resignation of Franz Josef Strauss, Defence Minister, who had decidedly overstepped his competence during the crisis. Adenauer was still wounded by his brief run for president, and this episode damaged his reputation even further. He announced that he would step down in the fall of 1963. His successor was to be Ludwig Erhard.

In the early 1960s the rate of economic growth slowed down significantly. In 1962 growth rate was 4.7% and the following year, 2.0%. After a brief recovery, the growth rate slowed again into a recession, with no growth in 1967.

A new coalition was formed to deal with this problem. Erhard stepped down in 1966 and was succeeded by Kurt Georg Kiesinger. He led a grand coalition between West Germany's two largest parties, the CDU/CSU and the Social Democratic Party (SPD). This was important for the introduction of new emergency acts: the grand coalition gave the ruling parties the two-thirds majority of votes required for their ratification. These controversial acts allowed basic constitutional rights such as freedom of movement to be limited in case of a state of emergency.
During the time leading up to the passing of the laws, there was fierce opposition to them, above all by the Free Democratic Party, the rising German student movement, a group calling itself ("Democracy in Crisis") and members of the Campaign against Nuclear Armament. A key event in the development of open democratic debate occurred in 1967, when the Shah of Iran, Mohammad Reza Pahlavi, visited West Berlin. Several thousand demonstrators gathered outside the Opera House where he was to attend a special performance. Supporters of the Shah (later known as ), armed with staves and bricks attacked the protesters while the police stood by and watched. A demonstration in the centre was being forcibly dispersed when a bystander named Benno Ohnesorg was shot in the head and killed by a plainclothes policeman. (It has now been established that the policeman, Kurras, was a paid spy of the East German security forces.) Protest demonstrations continued, and calls for more active opposition by some groups of students were made, which was declared by the press, especially the tabloid newspaper, as a massive disruption to life in Berlin, in a massive campaign against the protesters. Protests against the US intervention in Vietnam, mingled with anger over the vigour with which demonstrations were repressed led to mounting militance among the students at the universities in Berlin. One of the most prominent campaigners was a young man from East Germany called Rudi Dutschke who also criticised the forms of capitalism that were to be seen in West Berlin. Just before Easter 1968, a young man tried to kill Dutschke as he bicycled to the student union, seriously injuring him. All over West Germany, thousands demonstrated against the Springer newspapers which were seen as the prime cause of the violence against students. Trucks carrying newspapers were set on fire and windows in office buildings broken.

In the wakes of these demonstrations, in which the question of America's role in Vietnam began to play a bigger role, came a desire among the students to find out more about the role of the parent-generation in the Nazi era. The proceedings of the War Crimes Tribunal at Nuremberg had been widely publicised in Germany but until a new generation of teachers, educated with the findings of historical studies, could begin to reveal the truth about the war and the crimes committed in the name of the German people. One courageous attorney, Fritz Bauer patiently gathered evidence on the guards of the concentration camp and about twenty were put on trial in Frankfurt in 1963. Daily newspaper reports and visits by school classes to the proceedings revealed to the German public the nature of the concentration camp system and it became evident that the was of vastly greater dimensions than the German population had believed. (The term "Holocaust" for the systematic mass-murder of Jews first came into use in 1979, when an American mini-series with that name was shown on German television.) The processes set in motion by the Auschwitz trial reverberated decades later.

The calling in question of the actions and policies of government led to a new climate of debate. The issues of emancipation, colonialism, environmentalism and grass roots democracy were discussed at all levels of society. In 1979 the environmental party, the Greens, reached the 5% limit required to obtain parliamentary seats in the Free Hanseatic City of Bremen provincial election. Also of great significance was the steady growth of a feminist movement in which women demonstrated for equal rights. Until 1977 a married woman had to have the permission of her husband if she wanted to take on a job or open a bank account. Further reforms in 1979 to parental rights law gave equal legal rights to the mother and the father, abolishing the legal authority of the father. Parallel to this, a gay movement began to grow in the larger cities, especially in West Berlin, where homosexuality had been widely accepted during the twenties in the Weimar Republic.
Anger over the treatment of demonstrators following the death of Benno Ohnesorg and the attack on Rudi Dutschke, coupled with growing frustration over the lack of success in achieving their aims led to growing militance among students and their supporters. In May 1968, three young people set fire to two department stores in Frankfurt, they were brought to trial and made very clear to the court that they regarded their action as a legitimate act in what they described as the "struggle against imperialism". The student movement began to split into different factions, ranging from the unattached liberals to the Maoists and supporters of direct action in every form—the anarchists. Several groups set as their objective the aim of radicalising the industrial workers and taking an example from activities in Italy of the Red Brigades (), many students went to work in the factories, but with little or no success. The most notorious of the underground groups was the "", later known as the Red Army Faction which began by making bank raids to finance their activities and eventually went underground having killed a number of policemen, several bystanders and eventually two prominent West Germans, whom they had taken captive in order to force the release of prisoners sympathetic to their ideas. In the 1990s attacks were still being committed under the name "RAF". The last action took place in 1993 and the group announced it was giving up its activities in 1998. Evidence that the groups had been infiltrated by German Intelligence undercover agents has since emerged, partly through the insistence of the son of one of their prominent victims, the State Counsel Buback.

In the 1969 election, the SPD—headed by Willy Brandt—gained enough votes to form a coalition government with the FDP. Although Chancellor for only just over four years, Willy Brandt was one of the most popular politicians in the whole period. Brandt was a gifted speaker and the growth of the Social Democrats from there on was in no small part due to his personality. Brandt began a policy of rapprochement with West Germany's eastern neighbours, a policy opposed by the CDU. The issue of improving relations with Poland, Czechoslovakia and East Germany made for an increasingly aggressive tone in public debates but it was a huge step forward when Willy Brandt and the Foreign Minister, Walther Scheel (FDP) negotiated agreements with all three countries. (Moscow Agreement, August 1970, Warsaw Agreement, December 1970, Four Power Agreement over the status of West Berlin in 1971 and an agreement on relations between West and East Germany, signed in December 1972.) These agreements were the basis for a rapid improvement in the relations between east and west and led, in the long-term to the dismantlement of the Warsaw Treaty and the Soviet Union's control over Eastern Europe. Chancellor Brandt was forced to resign in May 1974, after Günter Guillaume, a senior member of his staff, was uncovered as a spy for the East German intelligence service, the. Brandt's contributions to world peace led to his nomination for the Nobel Peace Prize in 1971.

Finance Minister Helmut Schmidt (SPD) formed a coalition and he served as Chancellor from 1974 to 1982. Hans-Dietrich Genscher, a leading FDP official, became Vice Chancellor and Foreign Minister. Schmidt, a strong supporter of the European Community (EC) and the Atlantic alliance, emphasized his commitment to "the political unification of Europe in partnership with the USA".

In October 1982 the SPD–FDP coalition fell apart when the FDP joined forces with the CDU/CSU to elect CDU Chairman Helmut Kohl as Chancellor in a constructive vote of no confidence. Following national elections in March 1983, Kohl emerged in firm control of both the government and the CDU. The CDU/CSU fell just short of an absolute majority, due to the entry into the Bundestag of the Greens, who received 5.6% of the vote.

In January 1987 the Kohl–Genscher government was returned to office, but the FDP and the Greens gained at the expense of the larger parties. Kohl's CDU and its Bavarian sister party, the CSU, slipped from 48.8% of the vote in 1983 to 44.3%. The SPD fell to 37%; long-time SPD Chairman Brandt subsequently resigned in April 1987 and was succeeded by Hans-Jochen Vogel. The FDP's share rose from 7% to 9.1%, its best showing since 1980. The Greens' share rose to 8.3% from their 1983 share of 5.6%.

With the collapse of communism in Central and Eastern Europe in 1989, symbolised by the opening of the Berlin Wall, there was a rapid move towards German reunification; and a final settlement of the post-war special status of Germany. Following democratic elections, East Germany declared its accession to the Federal Republic subject to the terms of the Unification Treaty between the two states; and then both West Germany and East Germany radically amended their respective constitutions in accordance with that Treaty's provisions. East Germany then dissolved itself, and its five post-war states () were reconstituted, along with the reunited Berlin which ended its special status and formed an additional. They formally joined the Federal Republic on 3 October 1990, raising the number of states from 10 to 16, ending the division of Germany. The expanded Federal Republic retained West Germany's political culture and continued its existing memberships in international organisations, as well as its Western foreign policy alignment and affiliation to Western alliances like NATO and the European Union.

The official German reunification ceremony on 3 October 1990 was held at the building, including Chancellor Helmut Kohl, President Richard von Weizsäcker, former Chancellor Willy Brandt and many others. One day later, the parliament of the united Germany would assemble in an act of symbolism in the Reichstag building.

However, at that time, the role of Berlin had not yet been decided upon. Only after a fierce debate, considered by many as one of the most memorable sessions of parliament, the concluded on 20 June 1991, with quite a slim majority, that both government and parliament should move to Berlin from Bonn.

The West German ("economic miracle", coined by "The Times" in 1950) was due to the economic aid provided by the United States and the Marshall Plan. This improvement was sustained by the currency reform of 1948 which replaced the with the and halted rampant inflation. The Allied dismantling of the West German coal and steel industry finally ended in 1950.

As demand for consumer goods increased after World War II, the resulting shortage helped overcome lingering resistance to the purchase of German products. At the time Germany had a large pool of skilled and cheap labour, partly as a result of the flight and expulsion of Germans from Central and Eastern Europe, which affected up to 16.5 million Germans. This helped Germany to more than double the value of its exports during the war. Apart from these factors, hard work and long hours at full capacity among the population and in the late 1950s and 1960s extra labour supplied by thousands of ("guest workers") provided a vital base for the economic upturn. This would have implications later on for successive German governments as they tried to assimilate this group of workers.

From the late 1950s onwards, West Germany had one of the strongest economies in the world, almost as strong as before the Second World War. The East German economy showed a certain growth, but not as much as in West Germany, partly because of continued reparations to the USSR in terms of resources.

In 1952 West Germany became part of the European Coal and Steel Community, which would later evolve into the European Union. On 5 May 1955 West Germany was declared to have the "authority of a sovereign state". The British, French and U.S. militaries remained in the country, just as the Soviet Army remained in East Germany. Four days after obtaining the "authority of a sovereign state" in 1955, West Germany joined NATO. The UK and the USA retained an especially strong presence in West Germany, acting as a deterrent in case of a Soviet invasion. In 1976 West Germany became one of the founding nations of the Group of Six (G6). In 1973, West Germany—home to roughly 1.26% of the world's population—featured the world's fourth largest GDP of 944 billion (5.9% of the world total). In 1987 the FRG held a 7.4% share of total world production.

Religious affiliation in West Germany decreased from the 1960s onward. Religious affiliation declined faster among Protestants than among Catholics, causing the Roman Catholic Church to overtake the EKD as the largest denomination in the country during the 1970s.

The official position of West Germany concerning East Germany at the outset was that the West German government was the only democratically elected, and therefore the only legitimate, representative of the German people. According to the Hallstein Doctrine, any country (with the exception of the USSR) that recognised the authorities of the German Democratic Republic would not have diplomatic relations with West Germany.

In the early 1970s, Willy Brandt's policy of "" led to a form of mutual recognition between East and West Germany. The Treaty of Moscow (August 1970), the Treaty of Warsaw (December 1970), the Four Power Agreement on Berlin (September 1971), the Transit Agreement (May 1972), and the Basic Treaty (December 1972) helped to normalise relations between East and West Germany and led to both German states joining the United Nations. The Hallstein Doctrine was relinquished, and West Germany ceased to claim an exclusive mandate for Germany as a whole.

Following the Ostpolitik the West German view was that East Germany was a "de facto" government within a single German nation and a "de jure" state organisation of parts of Germany outside the Federal Republic. The Federal Republic continued to maintain that it could not within its own structures recognise the GDR "de jure" as a sovereign state under international law; while at the same time acknowledging that, within the structures of international law, the GDR was an independent sovereign state. By distinction, West Germany then viewed itself as being within its own boundaries, not only the "de facto" and "de jure" government, but also the sole "de jure" legitimate representative of a dormant "Germany as whole". The two Germanys relinquished any claim to represent the other internationally; which they acknowledged as necessarily implying a mutual recognition of each other as both capable of representing their own populations "de jure" in participating in international bodies and agreements, such as the United Nations and the Helsinki Final Act.

This assessment of the Basic Treaty was confirmed in a decision of the Federal Constitutional Court in 1973;

The West German Constitution (, "Basic Law") provided two articles for the unification with other parts of Germany:After the peaceful revolution of 1989 in East Germany, the Volkskammer of the GDR on 23 August 1990 declared the accession of East Germany to the Federal Republic under Article 23 of the Basic Law; and so initiated the process of reunification, to come into effect on 3 October 1990. Nevertheless, the act of reunification itself (with its many specific terms and conditions; including fundamental amendments to the West German Basic Law) was achieved constitutionally by the subsequent Unification Treaty of 31 August 1990; that is through a binding agreement between the former GDR and the Federal Republic now recognising each another as separate sovereign states in international law. This treaty was then voted into effect on 20 September 1990 by both the Volkskammer and the Bundestag by the constitutionally required two-thirds majorities; effecting on the one hand, the extinction of the GDR and the re-establishment of on the territory of East Germany; and on the other, the agreed amendments to the Basic Law of the Federal Republic. Amongst these amendments was the repeal of the very Article 23 in respect of which the GDR had nominally declared its postdated accession to the Federal Republic.

The two German states entered into a currency and customs union in July 1990, and on 3 October 1990, the German Democratic Republic dissolved and the re-established five East German (as well as a unified Berlin) joined the Federal Republic of Germany, bringing an end to the East-West divide.

Political life in West Germany was remarkably stable and orderly. The Adenauer era (1949–63) was followed by a brief period under Ludwig Erhard (1963–66) who, in turn, was replaced by Kurt Georg Kiesinger (1966–69). All governments between 1949 and 1966 were formed by the united caucus of the Christian-Democratic Union (CDU) and Christian Social Union (CSU), either alone or in coalition with the smaller Free Democratic Party (FDP) or other right-wing parties.
Kiesinger's 1966–69 "Grand Coalition" was between West Germany's two largest parties, the CDU/CSU and the Social Democratic Party (SPD). This was important for the introduction of new emergency acts—the Grand Coalition gave the ruling parties the two-thirds majority of votes required to see them in. These controversial acts allowed basic constitutional rights such as freedom of movement to be limited in case of a state of emergency.

Leading up to the passing of the laws, there was fierce opposition to them, above all by the FDP, the rising German student movement, a group calling itself ("Democracy in a State of Emergency") and the labour unions. Demonstrations and protests grew in number, and in 1967 the student Benno Ohnesorg was shot in the head by a policeman. The press, especially the tabloid newspaper, launched a campaign against the protesters.

By 1968 a stronger desire to confront the Nazi past had come into being. In the 1970s environmentalism and anti-nationalism became fundamental values among left-wing Germans. As a result, in 1979 the Greens were able to reach the 5% minimum required to obtain parliamentary seats in the Free Hanseatic City of Bremen state election, and with the foundation of the national party in 1980 developed into one of the most politically successful green movements in the world.

Another result of the unrest in the 1960s was the founding of the Red Army Faction (RAF). The RAF was active from 1968, carrying out a succession of terrorist attacks in West Germany during the 1970s. Even in the 1990s, attacks were still being committed under the name "RAF". The last action took place in 1993, and in 1998 the group announced it was ceasing activities.
In the 1969 election, the SPD gained enough votes to form a coalition government with the FDP. SPD leader and Chancellor Willy Brandt remained head of government until May 1974, when he resigned after the Guillaume Affair, in which a senior member of his staff was uncovered as a spy for the East German intelligence service, the. However the affair is widely considered to have been merely a trigger for Brandt's resignation, not a fundamental cause. Instead, Brandt, dogged by scandal relating to alcohol and depression as well as the economic fallout of the 1973 oil crisis, almost seems simply to have had enough. As Brandt himself later said, "I was exhausted, for reasons which had nothing to do with the process going on at the time".

Finance Minister Helmut Schmidt (SPD) then formed a government, continuing the SPD–FDP coalition. He served as Chancellor from 1974 to 1982. Hans-Dietrich Genscher, a leading FDP official, was Vice Chancellor and Foreign Minister in the same years. Schmidt, a strong supporter of the European Community (EC) and the Atlantic alliance, emphasized his commitment to "the political unification of Europe in partnership with the USA".

The goals of SPD and FDP however drifted apart in the late 1970s and early 1980s. On 1 October 1982 the FDP joined forces with the CDU/CSU to elect CDU Chairman Helmut Kohl as Chancellor in a constructive vote of no confidence. Following national elections in March 1983, Kohl emerged in firm control of both the government and the CDU. The CDU/CSU fell just short of an absolute majority, because of the entry into the Bundestag of the Greens, who received 5.6% of the vote.

In January 1987 the Kohl–Genscher government was returned to office, but the FDP and the Greens gained at the expense of the larger parties. The Social Democrats concluded that not only were the Greens unlikely to form a coalition, but also that such a coalition would be far from a majority. Neither condition changed until 1998.

In 1951 several laws were passed, ending the denazification. As a result, many people with a former Nazi past ended up again in the political apparatus of West Germany. German President Walter Scheel and Chancellor Kurt Georg Kiesinger were both former members of the Nazi Party. In 1957, 77% of the German Ministry of Justice's senior officials were former Nazi Party members. Konrad Adenauer's State Secretary Hans Globke had played a major role in drafting anti-semitic Nuremberg Race Laws in Nazi Germany.

In many aspects, German culture continued in spite of the dictatorship and wartime. Old and new forms coexisted next to each other, and the American influence, already strong in the 1920s, grew.

In the 20th century, association football became the largest sport in Germany. The Germany national football team, established in 1900, continued its tradition based in the Federal Republic of Germany, winning the 1954 FIFA World Cup in a stunning upset dubbed the miracle of Bern. Earlier, the German team was not considered part of the international top. The 1974 FIFA World Cup was held in West German cities and West Berlin. After having been beaten by their East German counterparts in the first round, the team of the German Football Association won the cup again, defeating the Netherlands 2–1 in the final. With the process of unification in full swing in the summer of 1990, the Germans won a third World Cup, with players that had been capped for East Germany not yet permitted to contribute. European championships have been won too, in 1972, 1980 and 1996.

After both Olympic Games of 1936 had been held in Germany, Munich was selected to host the 1972 Summer Olympics. These were also the first summer games in which the East Germans showed up with the separate flag and anthem of the GDR. Since the 1950s, Germany at the Olympics had been represented by a united team led by the pre-war German NOC officials as the IOC had denied East German demands for a separate team.

As in 1957, when the Saarland acceded, East German sport organisations ceased to exist in late 1990 as their subdivisions and their members joined their Western counterparts. Thus, the present German organisations and teams in football, Olympics and elsewhere are identical to those that had been informally called "West German" before 1991. The only differences were a larger membership and a different name used by some foreigners. These organisations and teams in turn mostly continued the traditions of those that represented Germany before the Second World War, and even the First World War, thus providing a century-old continuity despite political changes. On the other hand, the separate East German teams and organisations were founded in the 1950s; they were an episode lasting less than four decades, yet quite successful in that time.

As of 2012, West Germany have played a record 43 matches at the European Championships.

Besides the interest in the older generation of writers, new authors emerged on the background of the experiences of war and after war period. Wolfgang Borchert, a former soldier who died young in 1947, is one of the best known representatives of the. Heinrich Böll is considered an observer of the young Federal Republic from the 1950s to the 1970s, and caused some political controversies because of his increasingly critical view on society. The Frankfurt Book Fair (and its Peace Prize of the German Book Trade) soon developed into a regarded institution. Exemplary for West Germany's literature are – among others – Siegfried Lenz (with "The German Lesson") and Günter Grass (with "The Tin Drum" and "The Flounder").

During the 40 years of separation some divergence occurred in the cultural life of the two parts of the severed nation. Both West Germany and East Germany followed along traditional paths of the common German culture, but West Germany, being obviously more affected by influences from western Europe and North America, became more cosmopolitan. Conversely, East Germany, while remaining more conservative than West Germany in its adherence to some aspects of the received tradition, was strongly moulded by the dictates of a state socialist ideology of predominantly Soviet inspiration. On the non-political level, East Germany was also influenced by the Eastern Bloc's Slavic cultures that manifested in art, culinary scene, and sports. Nevertheless, young East Germans were also fascinated by Western and particularly American culture, which they had a degree of access to in a variety of ways, not least through West German television and radio, whose broadcasts reached many parts of the country.

For the majority of Germans in present-day Germany who lived in pre-reunification West Germany, there has been minimal change in daily life stemming from German reunification as the reunified country is essentially West Germany incorporating East Germany on a West German base. In contrast, for East Germans the scale of change has been sweeping in all aspects of life from that before. Although movements like exist attempting to celebrate and preserve parts of the GDR culture, since reunification the former East Germany has been converging towards the western part of the country in most parts of daily life.

In West Germany, most of the political agencies and buildings were located in Bonn, while the German Stock Market was located in Frankfurt am Main, which became the economic center. The judicial branch of both the German Federal Constitutional Court () and the highest Court of Appeals, were located in Karlsruhe.

The West German government was known to be much more decentralised than its state socialist East German counterpart, the former being a federal state and the latter a unitary one. Whilst East Germany was divided into 15 administrative districts (), which were merely local branches of the national government, West Germany was divided into states () with independently elected state parliaments and control of the, the second legislative chamber of the Federal Government.

Today, North Rhine-Westphalia is often considered to be Western Germany in geographical terms. When distinguishing between former West Germany and former East Germany as parts of present-day unified Germany, it has become most common to refer to the (old states) and the (new states), although and are still heard as well.
