Timeline of Enlargement of the United Nations
1940s
1945 (original members)
The UN officially came into existence on 24 October 1945, after ratification of the United Nations Charter by the five permanent members of the United Nations Security Council (China, France, the Soviet Union, the United Kingdom, and the United States) and a majority of the other signatories. A total of 51 original members (or founding members) joined that year; 50 of them signed the Charter at the United Nations Conference on International Organization in San Francisco on 26 June 1945, while Poland, which was not represented at the conference, signed it on 15 October 1945.
