The Warsaw Pact (WP), formally the Treaty of Friendship, Cooperation and Mutual Assistance (TFCMA), was a collective defence treaty signed in Warsaw, Poland, between the Soviet Union and seven other Eastern Bloc socialist republics in Central and Eastern Europe in May 1955, during the Cold War.

It was formally established in 1951 by the Treaty of Paris, signed by Belgium, France, Italy, Luxembourg, the Netherlands, and West Germany and was generally seen as the first step in the process of European integration following the end of the Second World War in Europe.

The United Nations (UN) is an international intergovernmental organization established by the signing of the Charter of the United Nations on 26 June 1945 with the articulated mission of maintaining international peace and security, to develop friendly relations among states, to promote international cooperation, and to serve as a centre for harmonizing the actions of states in achieving those goals.

Founded in the aftermath of World War II, NATO was established with the signing of the North Atlantic Treaty in 1949.

The WHO was established on 7 April 1948, and formally began its work on 1 September 1948.
