Dates of existence
On 5 March 1945, the United States, on behalf of itself, China, the Soviet Union, and the United Kingdom, invited governments that had signed or adhered to the United Nations Declaration of 1942 and had declared war against Germany or Japan to participate in the United Nations Conference on International Organization (UNCIO), to be held in San Francisco, U.S.A., beginning on 25 April 1945.
At the Conference, delegates of 50 nations worked to complete a United Nations charter, which was to be based on, inter alia, proposals established the previous year by representatives of China, the Soviet Union, the United Kingdom and the United States at the Dumbarton Oaks estate in Washington, D.C., U.S.A. (a.k.a. the Dumbarton Oaks Proposals).
The Conference was divided into four commissions and twelve technical committees. The four commissions, each led by a president, were:
Commission I, General Provisions; Commission II, General Assembly; Commission III, Security Council; and Commission IV, International Court of Justice.
The commissions were further divided into committees, which formulated recommendations based on relevant chapters of the Dumbarton Oaks Proposals.
Mr. Alger Hiss served as the Conference's secretary-general, and Mr. John Ross served as deputy secretary-general.
The Conference ended on 26 June 1945 with the signing of the United Nations Charter. On 24 October 1945, the five permanent members of the Security Council and 24 other signatory states deposited their ratifications of the Charter with the United States government, thereby officially establishing the United Nations.
