The German Democratic Republic is the first socialist state on the territory of Germany. The GDR was formed on October 7, 1949 on the site of the former Soviet occupation zone of Germany in East Germany four years after the end of World War II. At the time of the adoption of the proclamation, the GDR was admitted by the USSR, Poland, Czechoslovakia, Hungary, Romania, Bulgaria and Finland (the latter also admitted the FRG, the rest of the countries admitted the FRG only in 1955).
The German Democratic Republic bordered on the west with Germany, on the southeast with Czechoslovakia and on the east with Poland, on the north it was washed by the Baltic Sea. Having taken over the political regime from the Soviet Union, the GDR was one of the leading countries of the socialist camp throughout the Cold War.
Although a unified Germany was divided into the FRG and the GDR, a partial sporting unity of Germany remained until 1965 — the GDR and the FRG had a single Olympic team. Also, until 1969, the church unity of Germany was preserved: a single Protestant religious organization, the Evangelical Church of Germany, operated throughout Germany, but in 1969, eight East German land churches formed the Union of Evangelical Churches of the GDR. In 1972, the GDR and the FRG admitted each other, after which the declaration of the GDR by the rest of the states began, and in 1973 both Germans were admitted to the UN. The GDR was one of the main members of the Warsaw Pact Organization, until the destruction of the Berlin Wall and the unification of Germany in 1990. On October 3, 1990, it became part of the Federal Republic of Germany.
