The Soviet Union moved with fear in response to the anti-communist formation NATO . The soviet Union concluded the Warsaw Pact with its satellites in May 1955. It included all communist states in Europe - Soviet Russia, Albania, Bulgaria, Hungary, Poland, Romania, Czechoslovakia and East Germany. The Pact spoke of peaceful intentions and defense. It allowed its members to participate in any other coalition or alliance but it assured members of immediate assistance, including the use of armed force, in the event of armed aggression from other countries. To provide for military assistance, a Russian Supreme Commander was appointed to lead the combined armed forces of its members. A committee was established to foster political understanding of its members.
In the Late 1980's the anti-soviet and anti communist movements through eastern Europe began to crack to the war saw pact. Members from the pact started to leave because they wanted to get away from communism.
The Soviet Union gave up their control of the war saw pact. A few months later the committee met one last time and they talked about what they accomplished. After that meeting the Warsaw pact was ended.
On March 31st, 1991 the Warsaw pact ended.
