The Warsaw Pact—officially known as the Warsaw Treaty or Warsaw Pact among its member states, but commonly referred to in the West as the Warsaw Treaty—was a military assistance agreement for the so-called Eastern Bloc under the leadership of the Soviet Union from 1955 to 1991. It was established by the Warsaw Treaty of Friendship, Cooperation, and Mutual Assistance (abbreviated as the Warsaw Pact) and formed the North Atlantic Treaty Organization, a US-style NATO alliance, during the Cold War. Economically, the Eastern Bloc countries had been bound together by the Council for Mutual Economic Assistance since 1949. With the fall of the Iron Curtain, the Warsaw Pact's rigid structure increasingly eroded, and it was officially dissolved in 1991.
