Historical Trajectory
Phase I: Rise
West Germany was established on 23 May 1949 from the American, British, and French occupation zones following World War II. Chancellor Konrad Adenauer, in office until 1963, firmly anchored the new state within NATO rather than pursuing neutrality, and pursued agreements that laid groundwork for the European Union. The Saarland rejoined in 1957, and three southwestern states merged to form Baden-Württemberg in 1952, consolidating the federal structure.
Phase II: Zenith
The Wirtschaftswunder—economic miracle—of the 1950s lifted West Germany from wartime devastation to become the world's second-largest economy within a decade. A founding member of the G6 in 1975, West Germany anchored Western European economic integration through the European Economic Community. Its political stability, export-driven industrial base, and strong social market economy set a model emulated across postwar Europe.
Phase III: Decline
The fall of the Berlin Wall in November 1989 accelerated events rapidly. East Germany voted to dissolve itself and accede to the Federal Republic in 1990. On 3 October 1990, five reconstituted eastern states and reunited Berlin formally joined, raising the total to sixteen states. The reunited Germany continued West Germany's institutional memberships, political culture, and Western alliances, with the Federal Republic simply expanding rather than being replaced.
