NATO and the Warsaw Pact

The North Atlantic Treaty Organisation is a military alliance established by the signing of the North Atlantic Treaty on April 4, 1949. The organisation established a way of collective security where its member states agree to mutual defence in response to an attack by any external party. The Warsaw Pact is the name given to the treaty between Albania, Bulgaria, Czechoslovakia, East Germany, Hungary, Poland, Romania, and the Soviet Union, which was signed in Poland in 1955 and was officially called ‘The Treaty of Friendship and Co-operation and Mutual Assistance’. The countries that formed these aliances are Albania, Bulgaria, Czechoslovakia, East Germany, Hungary, Poland, Romania, and the Soviet Union. They formed this because the members of the Warsaw Pact pledged to defend each other if one or more of the members were attacked.
