East and West Germany Reunite

At midnight on 3 October 1990, the black, red, and gold flag of the Federal Republic of Germany was raised in front of the Reichstag building in Berlin. This ceremonial moment marked the formal end of the German Democratic Republic and the culmination of an extraordinary diplomatic process that had unfolded across less than eleven months. After more than four decades of division rooted in the aftermath of World War II, the two separate German states officially joined together under a single legal order.

The partition had taken shape in 1949, when the American, British, and French occupation zones coalesced into the Federal Republic of Germany, while the Soviet zone was organized into the German Democratic Republic. Both entities operated under distinct ideological and economic systems throughout the Cold War, each restricted by Allied occupation frameworks. While West Germany anchored itself within Western European institutions and NATO, East Germany aligned with the Soviet bloc and heavily fortified its borders, notably dividing the historic metropolis of Berlin with a concrete wall in 1961.
