The primary purpose of the United Nations (UN) is to promote international cooperation and maintain global peace and security. Established in 1945 after World War II, the UN aims to prevent conflict, facilitate dialogue between nations, and address global challenges such as poverty, inequality, and human rights abuses. It provides a platform for member states to discuss and collaborate on issues affecting humanity. The UN also undertakes various humanitarian efforts and peacekeeping missions worldwide to promote stability and support development in countries in need.
