(Bonus) The Warsaw Pact

(Bonus) The Warsaw Pact (WP),[d] formally the Treaty of Friendship, Cooperation and Mutual Assistance (TFCMA),[e] was a collective defense treaty signed in Warsaw, Poland, between the Soviet Union and seven other Eastern Bloc socialist republics of Central and Eastern Europe in May 1955, during the Cold War. The term "Warsaw Pact" commonly refers to both the treaty itself and its resultant defensive alliance, the Warsaw Treaty Organization[5] (WTO).[f] The Warsaw Pact was the military and economic complement to the Council for Mutual Economic Assistance (Comecon), the regional economic organization for the Eastern Bloc states of Central and Eastern Europe. Dominated by the Soviet Union, the Warsaw Pact was established as a balance of power or counterweight to the North Atlantic Treaty Organization (NATO) and the Western Bloc.[17][18] There was no direct military confrontation between the two organizations; instead, the conflict was fought on an ideological basis and through proxy wars. Both NATO and the Warsaw Pact led to the expansion of military forces and their integration into the respective blocs.[18] The Warsaw Pact's largest military engagement was the Warsaw Pact invasion of Czechoslovakia, its own member state, in August 1968 (with the participation of all pact nations except Albania and Romania),[17] which, in part, resulted in Albania withdrawing from the pact less than one month later. The pact began to unravel with the spread of the Revolutions of 1989 through the Eastern Bloc, beginning with the Solidarity movement in Poland,[19] its electoral success in June 1989 and the Pan-European Picnic in August 1989.[20]
