Communism and the Cold War

1945 – 1989

After World War II, the world was divided by the Cold War, a period of tense rivalry between the communist Soviet Union and the capitalist United States. Communism, which emphasized state control over the economy and society, spread to Eastern Europe, China, and other parts of the world. The Cold War saw conflicts like the Korean War, the Cuban Missile Crisis, and the Vietnam War as the superpowers vied for global influence. Although direct war between the U.S. and the Soviet Union never occurred, the Cold War shaped global politics and led to an arms race that defined much of the 20th century.
