In what year did the United Nations officially form?

The formation of the United Nations took place in 1945, following the devastation of World War II. The organization was established to promote international cooperation, maintain peace and security, and prevent future conflicts. The UN Charter was signed on June 26, 1945, in San Francisco, and the official establishment of the United Nations occurred on October 24, 1945, which is now celebrated as United Nations Day.

This year was significant as the need for a new global organization to foster dialogue and cooperation among nations became clear after the conflict of World War II, which had highlighted the failures of the League of Nations. By contrast, the other years listed are associated with events that did not involve the establishment of this vital international body. For instance, 1939 marked the beginning of World War II, while 1950 and 1963 came years after the UN was already operational, focusing instead on specific developments within the organization or global events.
