The original name of the United Nations was the United Nations Conference on International Organization, or UNCIO.
This name was used during the initial planning and formation of the organization in 1944 and 1945. The UNCIO was held in San Francisco, California, and its primary purpose was to draft the United Nations Charter, which established the organization's structure and functions.
After the UN Charter was adopted and signed by the founding member states, the organization officially became known as the United Nations on October 24, 1945.
The name "United Nations" itself was coined by U.S. President Franklin D. Roosevelt, who used it in a 1941 declaration with the United Kingdom. The term refers to the idea of nations working together for peace and security, which was the core principle behind the establishment of the organization.
