14 May 1955, Warsaw (Poland), on signature of the Warsaw Treaty of Friendship, Cooperation and Mutual Assistance (Warsaw Pact), by the Heads of Governments of Albania, Bulgaria, Czechoslovakia, the German Democratic Republic, Hungary, Poland, Romania and USSR. Signature of the Treaty supplemented the bilateral long-term alliance treaties already in existence between the USSR and on the one hand and, on the other, Czechoslovakia (1943), Poland (1945), Bulgaria (1948), Hungary (1948), Romania (1948). The Treaty came into effect 5 June 1955. A further declaration on the nature of the Treaty was made at a meeting of representatives of member countries, 28 Jan 1956, Prague (Czechoslovakia). In Aug 1961 Albania ceased to participate in the work of the Organization and in Sep 1968 withdrew from WTO. The meeting held in Mar 1969, Budapest (Hungary), established the Committee of Defence Ministers and the Military Council. A Convention was signed, Apr 1973, Moscow (USSR), on the legal status, privileges and immunities of staff of the Joint Command of the Armed Forces. The Treaty was extended for a further ten years in June 1975. In Nov 1976, Bucharest (Romania), the Committee of Foreign Ministers was set up to reinforce political cooperation (first meeting in May 1977, Moscow). The Treaty was extended, 26 Apr 1985, for a further 20 years, until the year 2005, with an option to renew it then for a further 10 years. With the reunification of Germany in 1990, the German Democratic Republic no longer existed as a separate state and was therefore no longer a member. Following decision of meeting of foreign and defence ministers, 18 Feb 1991, Budapest, the military structure of the Pact was to be dismantled by 1 Apr 1991. Final meeting held 1 July 1991. Political dissolution was expected by Mar 1992, but the splitting of the Soviet Union into its republics and the formation of the Commonwealth of Independent States (CIS), Dec 1991, meant that the Pact effectively ceased to exist at that date.
