The purpose of the establishment of the United Nations in 1945 was to promote international cooperation and prevent future conflicts following the devastation of World War II. The UN aimed to create a platform for dialogue among nations, foster human rights, and address global issues such as poverty, health, and education. By establishing mechanisms for collective security through peacekeeping missions and economic development initiatives, the UN sought to maintain peace and stability in a world still grappling with the aftermath of war. Its founding marked a significant step in global governance and diplomacy.
