The Warsaw Pact was a major defense agreement signed in 1955 between the Soviet Union and seven other Eastern European nations. This alliance, formally known as the Treaty of Friendship, Cooperation, and Mutual Assistance, was created during the Cold War. Its main purpose was to act as a military counterweight to NATO and the Western Bloc, especially as West Germany began to rearm. The pact also had an economic side, working alongside the Council for Mutual Economic Assistance (Comecon) for the Eastern Bloc states.
Although there was no direct fighting between the Warsaw Pact and NATO, their rivalry involved ideological battles and proxy wars around the world. The biggest military operation by the Warsaw Pact was its invasion of Czechoslovakia in 1968, where most member states participated. Interestingly, the Soviet Union had actually tried to join NATO in 1954 and also proposed a wider European security treaty, but these ideas were rejected by Western powers. Many leaders, including the Soviets, worried about Germany becoming a military threat again after the devastation of World War II.
The Warsaw Pact began to fall apart with the spread of new movements and revolutions in Eastern Europe starting in 1989. East Germany officially withdrew from the pact in 1990, just before it reunited with West Germany. Finally, in February 1991, the alliance officially ceased to exist through a joint declaration by its remaining member states. In the years that followed, most of these former Warsaw Pact countries made the significant step of joining NATO.
