The 1980s were a defining period in the Cold War, and the Warsaw Pact served as a vital symbol of the Eastern Bloc's unity and commitment to socialism. Established in May 1955, the Warsaw Pact was a collective defense treaty signed in Warsaw, Poland, between the Soviet Union and seven other Eastern Bloc socialist republics.

This 1980 poster, designed by A. Levchenko, commemorates the 25th anniversary of the pact. The dominant blues, whites, and reds in Levchenko's design symbolize peace, unity, and the Soviet flag, while the depiction of different country flags underscores the theme of international cooperation. The design encapsulates the essence of the Warsaw Pact, emphasizing the Soviet Union's dominance and its role as a counterweight to NATO.

The Warsaw Pact's history is marked by significant events, such as the invasion of Czechoslovakia in August 1968, and its unraveling began with the spread of the Revolutions of 1989. East Germany withdrew following reunification in 1990, and the pact was declared at an end in 1991. Most former Soviet republics formed the Collective Security Treaty Organization, and the Warsaw Pact countries outside the USSR each joined NATO.
