Warsaw Pact
End of the Cold War

In 1989, popular civil and political public discontent toppled the Communist governments of the Warsaw Treaty countries. The beginning of the end of the Warsaw Pact, regardless of military power, was the Pan-European Picnic in August 1989. The event, which goes back to an idea by Otto von Habsburg, caused the mass exodus of GDR citizens and the media-informed population of Eastern Europe felt the loss of power of their rulers and the Iron Curtain broke down completely. Though Poland's new Solidarity government under Lech Wałęsa initially assured the Soviets that it would remain in the Pact, this broke the brackets of Eastern Europe, which could no longer be held together militarily by the Warsaw Pact. Independent national politics made feasible with the perestroika and liberal glasnost policies revealed shortcomings and failures (i.e. of the soviet-type economic planning model) and induced institutional collapse of the Communist government in the USSR in 1991. From 1989 to 1991, Communist governments were overthrown in Albania, Poland, Hungary, Czechoslovakia, East Germany, Romania, Bulgaria, Yugoslavia, and the Soviet Union.

As the last acts of the Cold War were playing out, several Warsaw Pact states (Poland, Czechoslovakia, and Hungary) participated in the US-led coalition effort to liberate Kuwait in the Gulf War.

On 25 February 1991, the Warsaw Pact was declared disbanded at a meeting of defence and foreign ministers from remaining Pact countries meeting in Hungary. On 1 July 1991, in Prague, the Czechoslovak President Václav Havel formally ended the 1955 Warsaw Treaty Organization of Friendship, Cooperation and Mutual Assistance and so disestablished the Warsaw Treaty after 36 years of military alliance with the USSR. The USSR disestablished itself in December 1991.
