The Warsaw Pact was the military complement to the Council for Mutual Economic Assistance (CoMEcon), the regional economic organization for the socialist states of Central and Eastern Europe . The Warsaw Pact was created in reaction to the integration of West Germany into NATO in 1955 per the London and Paris Conferences of 1954, but it is also considered to have been motivated by Soviet desires to maintain control over military forces in Central and Eastern Europe . </P> <P> The Warsaw Pact was established as a balance of power or counterweight to NATO; there was no direct confrontation between them . Instead, the conflict was fought on an ideological basis and in proxy wars . Both NATO and the Warsaw Pact led to the expansion of military forces and their integration into the respective blocs . Its largest military engagement was the Warsaw Pact invasion of Czechoslovakia in August 1968 (with the participation of all Pact nations except Albania, Romania and East Germany), which, in part, resulted in Albania withdrawing from the pact less than a month later . The Pact began to unravel in its entirety with the spread of the Revolutions of 1989 through the Eastern Bloc, beginning with the Solidarity movement in Poland and its electoral success in June 1989 . </P>
