When was the United Nations established?

The United Nations was officially established on October 24, 1945. This date is significant because it marks the day when the UN Charter came into force, following its ratification by the five permanent members of the Security Council and a majority of the other signatory states. The establishment of the UN aimed to promote peace, security, and cooperation among countries in the aftermath of World War II, and October 24 is now celebrated annually as United Nations Day. This highlights the importance of the organization in fostering international dialogue and collaboration.
