The United Nations officially came into existence on October 24, 1945. This organization was established in the aftermath of World War II, with the primary aim of promoting international cooperation, maintaining peace and security, and fostering social progress. The formation of the UN marked a significant shift toward a collaborative approach to global issues, replacing the ineffective League of Nations. The UN's charter emphasizes the importance of human rights, development, and humanitarian assistance, and it has played a pivotal role in addressing various global challenges since its inception.
