History of Germany
From antiquity to the modern era — the historical eras, key events, and narrative that shaped Germany.
Overview
GERMANY WAS UNITED on October 3, 1990. Unification brought together a people separated for more than four decades by the division of Europe into two hostile blocs in the aftermath of World War II. The line that divided the continent ran through a defeated and occupied Germany.
Historical Eras
The major periods of {country}’s history at a glance.
Germanic Antiquity
500 BCE – 843
Germanic tribes inhabited the territories east of the Rhine and north of the Danube, resisting Roman expansion — most famously when Arminius (Hermann) annihilated three Roman legions at the Battle of Teutoburg Forest in 9 CE. The Franks eventually unified much of the region under Charlemagne, who was crowned Holy Roman Emperor in 800. The Treaty of Verdun in 843 divided the Carolingian Empire, establishing the foundations of a distinct East Frankish realm that would become Germany.
Holy Roman Empire
843 – 1648
The medieval German kingdom coalesced under Saxon, Salian, and Hohenstaufen dynasties, with Otto I crowned the first Holy Roman Emperor in 962. Power struggles between emperors and popes, the Crusades, the Hanseatic League's commercial dominance, and Rudolf of Habsburg's rise in 1273 shaped the era. The Protestant Reformation, ignited by Martin Luther in 1517, shattered religious unity and culminated in the devastating Thirty Years' War, ended by the Peace of Westphalia in 1648.
German Confederation
1648 – 1871
Following Westphalia, hundreds of fragmented German states operated under loose imperial structures until Napoleon dissolved the Holy Roman Empire in 1806. The Congress of Vienna (1814–1815) replaced it with the German Confederation, a weak alliance of sovereign states. Prussia's ascendancy under Frederick the Great, the War of Austrian Succession, wars against Denmark and Austria, and Otto von Bismarck's shrewd diplomacy progressively consolidated German territories toward national unification.
Imperial Germany
1871 – 1918
Bismarck's wars of unification culminated in the proclamation of the German Empire at Versailles in 1871, with Prussian King Wilhelm I as Kaiser. Rapid industrialization made Germany one of the world's foremost economic and military powers, while Bismarck's dismissal by Kaiser Wilhelm II in 1890 ushered in more aggressive foreign policies. Germany's role in World War I (1914–1918), triggered by the assassination of Archduke Franz Ferdinand, ended in catastrophic defeat and the Kaiser's abdication.
Weimar, Third Reich & Division
1918 – 1990
The Weimar Republic struggled against economic collapse and political extremism before Adolf Hitler's Nazi regime seized power in 1933, unleashing World War II and the Holocaust. Defeat in 1945 left Germany occupied and divided: the democratic Federal Republic in the West and the Soviet-backed German Democratic Republic in the East, separated after 1961 by the Berlin Wall. Decades of Cold War division ended when mass protests and the Wall's opening in November 1989 led to formal reunification on October 3, 1990.
Unified Germany
1990 – present
Reunified Germany rapidly became the cornerstone of European integration, deepening its commitment to the European Union and NATO while absorbing the substantial economic and social costs of rebuilding the former East. Helmut Kohl, Gerhard Schröder, and Angela Merkel — Europe's longest-serving modern leader — guided Germany through the euro's adoption, the 2008 financial crisis, the eurozone debt crisis, and the 2015 refugee surge. Today Germany stands as Europe's largest economy and a central pillar of the postwar liberal international order.
