The purpose of the United Nations, established in 1945, was to promote international cooperation and prevent future conflicts following World War II. Its foundation aimed to foster dialogue among nations, uphold human rights, and facilitate peacekeeping efforts. By providing a platform for member states to engage in diplomacy, the UN sought to address various global challenges, including poverty, health crises, and environmental issues. The organization also aims to promote sustainable development and uphold the principles enshrined in the Universal Declaration of Human Rights.
