1955-05-14

In May 1955, the Soviet Union and seven Eastern European states signed a mutual defense treaty in Warsaw, creating the Warsaw Pact.

Background

Following NATO’s formation in 1949 and West Germany’s integration in 1955, Moscow responded with a counter-alliance. The Warsaw Treaty of Friendship, Cooperation, and Mutual Assistance established a military and political alliance under de facto Soviet command. Though framed as voluntary, the Pact functioned as an enforcement mechanism of Soviet control, coordinating foreign policy and military planning—often at the expense of national sovereignty. It later enabled interventions in Hungary (1956) and Czechoslovakia (1968), reinforcing Cold War tensions.
