United Nations founding, Aban 2. On this date in 1324 Jalali (1945 CE), the Charter of the United Nations came into force and the organization officially began its work. The United Nations was established to maintain international peace and security, promote friendly relations among nations, and encourage cooperation in solving global problems. Its main headquarters is located in New York City, and the organization initially had 51 member states. The founding of the United Nations was a direct response to the devastation of World War II, which resulted in millions of deaths and widespread destruction across many countries. The UN Charter was drafted at a conference in San Francisco and signed by the participating nations. After formal ratification, the Charter took effect on Aban 2, 1324, and the United Nations replaced the League of Nations as the primary international body for peace and cooperation. Today, the United Nations includes nearly all countries in the world and plays a significant role in managing international crises, providing humanitarian assistance, supporting human rights, and promoting sustainable development. Through its specialized agencies and various programs, the UN addresses issues such as global health, the environment, and education, and remains one of the most important international institutions. This observance was added to the Jalali calendar due to its historical significance and global impact; the date was designated to highlight the United Nations' role in international developments and cooperation among nations.
