Cold War: East Germany's parliament abolishes the constitutional provision granting the Communist Party the leading role in the state.

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, 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.
