The Warsaw Pact is formed

The Soviet Union and seven of its European satellites sign a treaty establishing the Warsaw Pact, a mutual defense organization that put the Soviets in command of the armed forces of the member states.

The Warsaw Pact, so named because the treaty was signed in Warsaw, included the Soviet Union, Albania, Poland, Romania, Hungary, East Germany, Czechoslovakia and Bulgaria as members. The treaty called on the member states to come to the defense of any member attacked by an outside force and it set up a unified military command under Marshal Ivan S. Konev of the Soviet Union. The introduction to the treaty establishing the Warsaw Pact indicated the reason for its existence. This revolved around “Western Germany, which is being remilitarized, and her inclusion in the North Atlantic bloc, which increases the danger of a new war and creates a threat to the national security of peace-loving states.” This passage referred to the decision by the United States and the other members of the North Atlantic Treaty Organization (NATO) on May 9, 1955 to make West Germany a member of NATO and allow that nation to remilitarize. The Soviets obviously saw this as a direct threat and responded with the Warsaw Pact
