The Cold War began in 1947 after World War II as tensions grew between the United States and its Western allies and the Soviet Union and its Eastern Bloc allies. Over several decades, the two superpowers competed for power and influence around the world through proxy wars, arms races, and propaganda. While direct military conflict was avoided, the Cold War had wide-ranging impacts, including the division of Germany and Korea, dictatorships in Latin America, and the space race. It ended in 1991 with the collapse of the Soviet Union.
