After 36 years in existence, the Warsaw Pact—the military alliance between the Soviet Union and its eastern European satellites—comes to an end. The action was yet another sign that the Soviet Union was losing control over its former allies and that the Cold War was falling apart.
The Warsaw Pact was formed in 1955, primarily as a response to the decision by the United States and its western European allies to include a rearmed West Germany in the North Atlantic Treaty Organization (NATO). NATO had begun in 1949 as a defensive military alliance between the United States, Canada, and several European nations to thwart possible Soviet expansion into Western Europe. In 1954, NATO nations voted to allow a rearmed West Germany into the organization. The Soviets responded with the establishment of the Warsaw Pact. The original members included the Soviet Union, East Germany, Poland, Hungary, Romania, Bulgaria, Czechoslovakia, and Albania. Although the Soviets claimed that the organization was a defensive alliance, it soon became clear that the primary purpose of the pact was to reinforce communist dominance in Eastern Europe. In Hungary in 1956, and then again in Czechoslovakia in 1968, the Soviets invoked the pact to legitimize its interventions in squelching anticommunist revolutions.
By the late-1980s, however, anti-Soviet and anticommunist movements throughout Eastern Europe began to crack the Warsaw Pact. In 1990, East Germany left the Warsaw Pact in preparation for its reunification with West Germany. Poland and Czechoslovakia also indicated their strong desire to withdraw. Faced with these protests—and suffering from a faltering economy and unstable political situation—the Soviet Union bowed to the inevitable. In March 1991, Soviet military commanders relinquished their control of Warsaw Pact forces. A few months later, the pact's Political Consultative Committee met for one final time and formally recognized what had already effectively occurred—the Warsaw Pact was no more.
