The establishment of the United Nations followed World War II, driven by the need for a global organization to promote peace and cooperation among nations. Key events included the devastation of the war, which highlighted the failures of the League of Nations, and the advocacy of leaders such as Franklin D. Roosevelt and Winston Churchill. The United Nations Charter was drafted in 1945, focusing on issues like human rights, conflict resolution, and international security. The UN was born out of a desire to prevent future wars and foster international dialogue, fundamentally shaping global governance and diplomacy.
