The
Warsaw Pact (formally, the
Treaty of Friendship, Co-operation, and Mutual Assistance, sometimes, informally
WarPac, akin in format to
NATO) was a
collective defense treaty among
Soviet Union and seven Soviet
satellite states in
Central and Eastern Europe in existence during the
Cold War. The Warsaw Pact was the military complement to the
Council for Mutual Economic Assistance (CoMEcon), the regional economic organization for the communist 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
Paris Pacts 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.
