Yes, you are correct! The alliance that East Germany belonged to but West Germany did not is the Warsaw Pact.

The Warsaw Pact was a political and military alliance formed in 1955 between the Soviet Union and its Eastern European satellite states, including East Germany. The main purpose of the Warsaw Pact was to counter the influence of NATO (North Atlantic Treaty Organization) in Europe during the Cold War.

History of the Warsaw Pact

The Warsaw Pact was established in response to the formation of NATO in 1949, which was seen as a threat by the Soviet Union and its allies. The pact was signed in Warsaw, Poland on May 14, 1955, and was initially comprised of eight member states, including the Soviet Union, East Germany, Poland, Czechoslovakia, Hungary, Romania, Bulgaria, and Albania.

Military Cooperation

One of the key aspects of the Warsaw Pact was its military cooperation among member states. The Soviet Union maintained a significant military presence in Eastern Europe and provided military support to its allies. The pact also facilitated joint military exercises and training, as well as the standardization of weapons and equipment among member states.

End of the Warsaw Pact

The Warsaw Pact officially ended on July 1, 1991, following the dissolution of the Soviet Union and the end of the Cold War. The member states of the pact gradually transitioned to new political systems and alliances, with many former Eastern Bloc countries joining NATO after the fall of the Soviet Union.
