Berlin in ruins after World War II

At the beginning of the German Revolution in November 1918, Germany was declared a republic. However, the struggle for power continued, with radical-left Communists seizing power in Bavaria. The revolution came to an end on 11 August 1919, when the democratic Weimar Constitution was signed by President Friedrich Ebert.[34] An era of increasing national confidence, a very liberal cultural life and decade of economic prosperity followed - known as the Golden Twenties. Suffering from the Great Depression of 1929, the harsh peace conditions dictated by the Treaty of Versailles, and a long succession of unstable governments, Germans increasingly lacked identification with the government in the early 1930s. This was exacerbated by a widespread right-wing Dolchstoßlegende, or stab-in-the-back legend, which argued that Germany had lost World War I because of those who wanted to overthrow the government. The Weimar government was accused of betraying Germany by signing the Versailles Treaty.
By 1932, the German Communist Party and the Nazi Party controlled the majority of Parliament, fuelled by discontent with the Weimar government. After a series of unsuccessful cabinets, President Paul von Hindenburg appointed Adolf Hitler as Chancellor of Germany on 30 January 1933.[35] On 27 February 1933 the Reichstag building went up in flames, and a consequent emergency decree abrogated basic citizens' rights. An enabling act passed in parliament gave Hitler unrestricted legislative power. Only the Social Democratic Party voted against it, while Communist MPs had already been imprisoned.[36][37] Using his powers to crush any actual or potential resistance, Hitler established a centralised totalitarian state within months. Industry was revitalised with a focus on military rearmament.[38]
In 1935, Germany reacquired control of the Saar and in 1936 military control of the Rhineland, both of which had been lost in the Treaty of Versailles.[39] In 1938, Austria was annexed, and in 1939, Czechoslovakia was brought under German control. The invasion of Poland was prepared through the Molotov–Ribbentrop pact and Operation Himmler. On 1 September 1939 the German Wehrmacht launched a blitzkrieg on Poland, which was swiftly occupied by Germany and by the Soviet Red Army. The UK and France declared war on Germany, marking the beginning of World War II.[40] As the war progressed, Germany and its allies quickly gained control of most of continental Europe and North Africa, though plans to force the United Kingdom to an armistice or surrender failed. On 22 June 1941, Germany broke the Molotov–Ribbentrop pact and invaded the Soviet Union. Japan's attack on Pearl Harbor led Germany to declare war on the United States. The Battle of Stalingrad forced the German army to retreat on the Eastern front.[40]

In September 1943, Germany's ally Italy surrendered, and German troops were forced to defend an additional front in Italy. D-Day opened a Western front, as Allied forces advanced towards German territory. On 8 May 1945, the German armed forces surrendered after the Red Army occupied Berlin.[41]
In what later became known as The Holocaust, the Third Reich regime had enacted policies directly subjugating many dissidents and minorities. Millions of people were murdered by the Nazis during the Holocaust, including several million Jews, Romani people, Slavic people, Soviet POWs, people with mental and/or physical disabilities, Jehovah's Witnesses, homosexuals, and members of the political and religious opposition.[42] World War II was responsible for more than 40 million dead in Europe.[43] The war casualties for Germany are estimated at 5.3 million German soldiers,[44] millions of German civilians;[45][46] and losing the war resulted in large territorial losses; the expulsion of about 15 million ethnic Germans from former eastern territories of Germany and other formerly occupied European countries; mass rape of German women;[47] and the destruction of numerous major cities. The Nuremberg trials of Nazi war criminals were held after World War II

Following the fall of Napoleon, the Congress of Vienna convened in 1814 and founded the German Confederation (Deutscher Bund), a loose league of 39 sovereign states. Disagreement with restoration politics partly led to the rise of liberal movements, followed by new measures of repression by Austrian statesman Metternich. The Zollverein, a tariff union, furthered economic unity in the German states.[27] National and liberal ideals of the French Revolution gained increasing support among many, especially young, Germans. In the light of a series of revolutionary movements in Europe, which established a republic in France, intellectuals and commoners started the Revolutions of 1848 in the German states. King Frederick William IV of Prussia was offered the title of Emperor, but with a loss of power; he rejected the crown and the proposed constitution, leading to a temporary setback for the movement.[28]

Conflict between King William I of Prussia and the increasingly liberal parliament erupted over military reforms in 1862, and the king appointed Otto von Bismarck the new Minister President of Prussia. Bismarck successfully waged war on Denmark in 1864. Prussian victory in the Austro-Prussian War of 1866 enabled him to create the North German Confederation (Norddeutscher Bund) and to exclude Austria, formerly the leading German state, from the federation's affairs. After the French defeat in the Franco-Prussian War, the German Empire was proclaimed in 1871 in Versailles, uniting all scattered parts of Germany except Austria (Kleindeutschland, or "Lesser Germany").
With almost two-thirds of its territory and population, Prussia was the dominating constituent of the new state; the Hohenzollern King of Prussia ruled as its concurrent Emperor, and Berlin became its capital.[28] In the Gründerzeit period following the unification of Germany, Bismarck's foreign policy as Chancellor of Germany under Emperor William I secured Germany's position as a great nation by forging alliances, isolating France by diplomatic means, and avoiding war. Under Wilhelm II, however, Germany, like other European powers, took an imperialistic course leading to friction with neighbouring countries. As a result of the Berlin Conference in 1884 Germany claimed several colonies including German East Africa, German South-West Africa, Togo, and Cameroon.[29] Most alliances in which Germany had previously been involved were not renewed, and new alliances excluded the country.[30]
The assassination of Austria's crown prince on 28 June 1914 triggered World War I. Germany, as part of the Central Powers, suffered defeat against the Allies in one of the bloodiest conflicts of all time. An estimated two million German soldiers died in World War I.[31] The German Revolution broke out in November 1918, and Emperor Wilhelm II and all German ruling princes abdicated. An armistice ended the war on 11 November, and Germany was forced to sign the Treaty of Versailles in June 1919. The treaty was perceived in Germany as a humiliating continuation of the war, and is often cited as an influence in the rise of Nazism

The Germanic tribes are thought to date from the Nordic Bronze Age or the Pre-Roman Iron Age. From southern Scandinavia and north Germany, they expanded south, east and west from the 1st century BC, coming into contact with the Celtic tribes of Gaul as well as Iranian, Baltic, and Slavic tribes in Central and Eastern Europe.[16] Under Augustus, the Roman General Publius Quinctilius Varus began to invade Germania (an area extending roughly from the Rhine to the Ural Mountains). In AD 9, three Roman legions led by Varus were defeated by the Cheruscan leader Arminius. By AD 100, when Tacitus wrote Germania, Germanic tribes had settled along the Rhine and the Danube (the Limes Germanicus), occupying most of the area of modern Germany; Austria, southern Bavaria and the western Rhineland, however, were Roman provinces.[17]
In the 3rd century a number of large West Germanic tribes emerged: Alemanni, Franks, Chatti, Saxons, Frisii, Sicambri, and Thuringii. Around 260, the Germanic peoples broke into Roman-controlled lands.[18] After the invasion of the Huns in 375, and with the decline of Rome from 395, Germanic tribes moved further south-west. Simultaneously several large tribes formed in what is now Germany and displaced the smaller Germanic tribes. Large areas (known since the Merovingian period as Austrasia) were occupied by the Franks, and Northern Germany was ruled by the Saxons and Slavs.[17]

On 25 December 800, the Frankish king Charlemagne was crowned emperor and founded the Carolingian Empire, which was divided in 843.[19] The Holy Roman Empire resulted from the eastern portion of this division. Its territory stretched from the Eider River in the north to the Mediterranean coast in the south.[19] Under the reign of the Ottonian emperors (919–1024), several major duchies were consolidated, and the German king was crowned Holy Roman Emperor of these regions in 962. The Holy Roman Empire absorbed northern Italy and Burgundy under the reign of the Salian emperors (1024–1125), although the emperors lost power through the Investiture Controversy.
Under the Hohenstaufen emperors (1138–1254), the German princes increased their influence further south and east into territories inhabited by Slavs, preceding German settlement in these areas and further east (Ostsiedlung). Northern German towns grew prosperous as members of the Hanseatic League.[20] Starting with the Great Famine in 1315, then the Black Death of 1348–50, the population of Germany plummeted.[21] The edict of the Golden Bull in 1356 provided the basic constitution of the empire and codified the election of the emperor by seven prince-electors who ruled some of the most powerful principalities and archbishoprics.[22]


Martin Luther initiated the Protestant Reformation
Martin Luther publicised The Ninety-Five Theses in 1517 in Wittenberg, challenging the Roman Catholic Church and initiating the Protestant Reformation. A separate Lutheran church became the official religion in many German states after 1530. Religious conflict led to the Thirty Years' War (1618–1648), which devastated German lands.[23] The population of the German states was reduced by about 30%.[24] The Peace of Westphalia (1648) ended religious warfare among the German states, but the empire was de facto divided into numerous independent principalities. In the 18th century, the Holy Roman Empire consisted of approximately 1,800 such territories.[25]
From 1740 onwards, dualism between the Austrian Habsburg Monarchy and the Kingdom of Prussia dominated German history. In 1806, the Imperium was overrun and dissolved as a result of the Napoleonic Wars
