The primary reason behind the development of the United Nations was to promote international cooperation and prevent future conflicts after the devastation of World War II. Formed in 1945, the UN aimed to address issues like peacekeeping, security, and human rights. Its founders sought to create a platform for dialogue among nations to resolve disputes diplomatically, enhancing global stability. The UN also focused on social progress and humanitarian efforts, reflecting a commitment to fostering a better world. The establishment of this organization embodied the hope for collective action against threats to peace and a shared pursuit of human welfare.
