- Significance
On 14 May 1955 the Soviet Union and seven Eastern European communist states signed the Treaty of Friendship, Cooperation and Mutual Assistance in Warsaw, creating the Warsaw Pact. The signatories were the Soviet Union, Albania, Bulgaria, Czechoslovakia, East Germany, Hungary, Poland and Romania.
The alliance was a direct response to the admission of the Federal Republic of Germany (West Germany) into NATO days earlier, which Moscow portrayed as a remilitarisation threat. The pact established a mutual-defence framework and a unified military command under Soviet leadership, formalising the Soviet Union's control over the armed forces of its satellite states. While presented as a counterpart to NATO, in practice it served to consolidate Soviet political and military dominance in Eastern Europe, as demonstrated by interventions in Hungary in 1956 and Czechoslovakia in 1968. The Warsaw Pact's creation completed the division of Europe into two opposing military blocs that defined the structure of the Cold War until its dissolution in 1991.
