The establishment of the United Nations' charter was precipitated by the devastating consequences of World War II. As wartime alliances sought to prevent future global conflicts, delegates from 50 nations convened in San Francisco in 1945 to draft the UN Charter. Key events leading up to the charter included the failure of the League of Nations, wartime cooperation among Allied powers, and the Holocaust's universal outcry for human rights protections. The charter emphasized international cooperation, peace, security, and the promotion of human rights. It laid the foundation for a multilateral framework aimed at fostering diplomacy and collective action to resolve conflicts.
