East Berlin

East Berlin (German: Ost-Berlin; pronounced [ˈɔstbɛʁˌliːn] ^ⓘ) was the partially recognised capital city of East Germany (GDR) from 1948 to 1990, although in 1945, it was recognised by the Three Powers (United States, United Kingdom, and France) as the Soviet occupation sector of Berlin. The American, British, and French sectors were known as West Berlin. From 13 August 1961 until 9 November 1989, East Berlin was separated from West Berlin by the Berlin Wall. The Western Allied powers did not recognize East Berlin as the GDR's capital, nor the GDR's authority to govern East Berlin. On 3 October 1990, the day Germany was officially reunified, East and West Berlin formally reunited as the city of Berlin.
