  • Cold War

    1945–1991Berlin, Germany

    After World War II, the Western Bloc led by the United States and the Eastern Bloc led by the Soviet Union engaged in a nearly half-century-long political, economic, and military confrontation. Although the two superpowers never fought directly, they competed globally through proxy wars, an arms race, and the Space Race. The Cold War began in the late 1940s and ended with the dissolution of the Soviet Union in 1991.

    1922–1991Moscow

    On December 30, 1922, the Treaty on the Creation of the USSR was signed at the Bolshoi Theatre in Moscow, officially establishing the Union of Soviet Socialist Republics. Plenipotentiary delegates from the Russian, Transcaucasian, Ukrainian, and Byelorussian Soviet republics signed the treaty, along with a declaration serving as its preamble. The treaty legally formalized the political union of the Soviet republics that had existed since 1919, creating a new federal government with centralized functions in Moscow. Legislative power was vested in the Congress of Soviets and the Central Executive Committee, while executive power lay with the Council of People's Commissars.
