In what year was the United Nations founded?

The United Nations was founded in 1945, immediately after the end of World War II. The organization was established to promote international cooperation, peace, and security, and aimed to prevent future conflicts on the scale of the world wars. The founding of the UN represented a significant shift in international relations, emphasizing the importance of collective action and diplomacy.

By bringing countries together to discuss and address global issues, the UN sought to provide a platform for dialogue and cooperation among nations. The official charter of the United Nations was adopted on June 26, 1945, in San Francisco, and the organization officially came into existence on October 24, 1945, which is now celebrated as United Nations Day.

The other years listed do not correspond to the establishment of the UN; 1940 is before the war's end, 1950 is too late during a time of the Cold War, and 1960 is well after the UN was already functioning as a significant global institution.
