Warsaw Pact (dissolved)

The Warsaw Pact, established in 1955, was a military alliance of Eastern European communist countries led by the Soviet Union, created in response to NATO. It aimed to counter Western influence during the Cold War, involving countries like Poland, East Germany, Czechoslovakia, Hungary, Romania, and Bulgaria. The pact allowed for collective defense and military cooperation among its members. However, the political landscape changed with the fall of communism in Eastern Europe in the late 1980s, leading to the dissolution of the Warsaw Pact in 1991, shortly before the Soviet Union itself collapsed.
