Cold War: East Germany closes the border between the eastern and western sectors of Berlin to thwart its inhabitants' attempts to escape to the West, and construction of the Berlin Wall is started. The day is known as Barbed Wire Sunday.
Cold War
The Cold War was a period of global geopolitical rivalry between the United States (US) and the Soviet Union (USSR) and their respective allies, the capitalist Western Bloc and communist Eastern Bloc, which began in the aftermath of the Second World War and ended with the dissolution of the Soviet Union in 1991. The term cold war is used because there was no direct fighting between the two superpowers, though each supported opposing sides in regional conflicts known as proxy wars. In addition to the struggle for ideological and economic influence and an arms race in both conventional and nuclear weapons, the Cold War was expressed through technological rivalries such as the Space Race, espionage, propaganda campaigns, embargoes, and sports diplomacy.
East Germany
East Germany, officially known as the German Democratic Republic (GDR), was a country in Central Europe from its formation on 7 October 1949 until its reunification with West Germany (FRG) on 3 October 1990. Until 1989, it was generally viewed as a communist state and described itself as a socialist "workers' and peasants' state". The economy of the country was centrally planned and state-owned. Although the GDR had to pay substantial war reparations to the Soviets, its economy became the most successful in the Eastern Bloc.
East Berlin
East Berlin was the partially recognised 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 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.
