The following is a list of United Nations member states arranged in chronological order according to their dates of admission (with the United Nations Security Council resolutions that recommended their admission and the United Nations General Assembly resolutions that admitted them, signified with SCR and GAR, respectively), including former members. Members denoted with "→" changed their names, had their memberships in the UN continued by a successor state, merged with other members, or were dissolved.

Timeline 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.
