East Berlin

East Berlin (German: Ost-Berlin; pronounced [ˈɔstbɛʁˌliːn] ) was the capital of East Germany (GDR) from 1949 to 1990. From 1945, it was 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. For most of its administrative existence, East Berlin was officially known as Berlin, capital of the GDR (German: Berlin, Hauptstadt der DDR) by the GDR government. On 3 October 1990, the day Germany was officially reunified, East and West Berlin formally reunited as the city of Berlin.

Overview

With the London Protocol of 1944 and subsequent Potsdam Conference in 1945, the Allied powers of the United States, the United Kingdom, and the Soviet Union decided to divide Germany into three occupation zones and to establish a special area of Berlin, which was occupied by the three Allied Forces together. In May 1945, the Soviet Union installed a city government for the whole city that was called "Magistrate of Greater Berlin", which existed until 1947. After the war, the Allied Forces initially administered the city together within the Allied Kommandatura, which served as the governing body of the city.
