The Communist Revolution in Russia in 1917 was a major factor in shaping the Cold War, as it led to the spread of communism to other countries and heightened tensions between the communist Eastern Bloc and the capitalist Western Bloc. The establishment of the Soviet Union as a communist superpower directly challenged the Western powers and ultimately contributed to the formation of two opposing alliances – NATO (North Atlantic Treaty Organization) in the West and the Warsaw Pact in the East. The Communist Revolution also inspired communist movements in other countries, leading to conflicts and proxy wars between the two sides throughout the Cold War.
