The United Nations (UN) was established in the post-WWII era to promote international cooperation, peace, and security. Formed in 1945, its primary goals included preventing future conflicts, fostering diplomatic relations, and encouraging human rights. The UN aimed to address global challenges such as poverty, disease, and humanitarian crises through various specialized agencies, including the World Health Organization (WHO) and the United Nations Educational, Scientific and Cultural Organization (UNESCO). The organization also plays a critical role in peacekeeping missions and mediating conflicts, demonstrating its commitment to collaborative efforts for global stability and development.
