The German Democratic Republic (East Germany), located on the great north European plain, ceased to exist in 1990. During the closing days of World War II in Europe, Soviet troops advancing into Germany from the east occupied the German provinces of Mecklenburg, Brandenburg, Saxony-Anhalt, Saxony and Thuringia. These five provinces comprised the occupation zone administered by the Soviet Union after the cessation of hostilities. The other three zones were administered by the United States, Great Britain and France. Under the Potsdam agreement, questions affecting Germany as a whole were to be settled by the commanders in chief of the occupation zones acting jointing and by unanimous decision. When Soviet intransigence rendered the quadripartite commission inoperable, the three western zones were united to form the Federal Republic of Germany, May 23, 1949. Thereupon the Soviet Union dissolved its occupation zone and established it as the Democratic Republic of Germany, Oct 7, 1949. East and West Germany became reunited as one country on Oct. 3, 1990.
