The German Democratic Republic (GDR; , DDR; more commonly known in English as East Germany) was a self-declared socialist state (but often referred to in the West as a "communist state") in the Eastern Bloc created in the Soviet Zone of occupied Germany and the Soviet sector of occupied Berlin. The German Democratic Republic existed from 7 October 1949 until 3 October 1990, when its re-established states acceded to the adjacent Federal Republic of Germany, thus producing the current form of the state of Germany.

In 1955, the Soviet Union declared that the Republic was fully sovereign. However, Soviet occupation troops remained in GDR territory, based on the four-power Potsdam Agreement, while British, Canadian, French and American forces remained in the Federal Republic of Germany in the West. Berlin, completely surrounded by GDR territory, was similarly divided with British, French and U.S. garrisons in West Berlin and Soviet forces in East Berlin. Berlin in particular became the focal point of Cold War tensions. East Germany was a member of the Warsaw Pact and a close ally of the Soviet Union.

Following the initial opening of sections of the Berlin Wall on 9 November 1989, new elections were held on 18 March 1990, and the governing party, the Socialist Unity Party of Germany, lost its majority in the Volkskammer (the East German parliament) soon after. On 23 August, the Volkskammer decided that the Republic would recreate the five pre-war states (which had been dissolved in 1952), which would join the Federal Republic of Germany on 3 October 1990. As a result of the reunification on that date, the German Democratic Republic ceased to exist.

Discussions at Yalta and Potsdam also outlined the planned occupation and administration of post-war Germany under a four-power Allied Control Council, or ACC, composed of the United States, United Kingdom, France, and the Soviet Union. At the Potsdam Conference in the summer of 1945, following the end of fighting in Europe, France, the United Kingdom, the United States and the Soviet Union decided to divide Germany into four occupation zones. Each country would control a part of Germany until its sovereignty was restored.

The Länder (states) of Mecklenburg-Vorpommern, Brandenburg, Saxony, Saxony-Anhalt, Thuringia, fell in the Soviet Zone of Germany (in German: Sowjetische Besatzungszone, or SBZ). Soviet objections to economic and political changes in western (US, UK, and French) occupation zones led to Soviet withdrawal from the ACC in 1948 and subsequent evolution of the SBZ into East Germany, including the Soviet sector of Berlin. Concurrently, the Western occupation zones consolidated to form West Germany (or the Federal Republic of Germany, FRG).
