The United Nations (UN) was created in 1945 after World War II to maintain world peace and prevent future conflicts. Established in the aftermath of the war, the UN aimed to foster international cooperation and dialogue among nations to address global challenges, including war, poverty, and human rights abuses. The organization brought together member states to promote peacekeeping efforts, development initiatives, and international law. The UN General Assembly and the Security Council became key platforms for addressing issues of security, diplomacy, and humanitarian aid, playing a vital role in shaping post-war international relations.
