East Germany

East-Germany, also known as the German Democratic Republic (GDR), in German known as Deutsche Demokratische Republik (DDR), is a former state in the Eastern Bloc, that existed during the Cold War from 1949 to 1990. It comprised the region of Germany that, after World War II, was occupied by the Russians, including East Berlin (but not West Berlin) [1].
