The Soviet Union and seven of its European satellites sign a treaty establishing the Warsaw Pact, a mutual defense organization that put the Soviets in command of the armed forces of the member states. * The Warsaw Pact, so named because the treaty was signed in Warsaw, included the Soviet Union, Albania, Poland, Romania, Hungary, East Germany, Czechoslovakia, and Bulgaria as members.
