  • On October 24, 1945, the United Nations (UN) was founded in San Francisco, California. The United Nations is an international organization charged with providing international law, monitoring human rights, encouraging economic progress, and working towards world peace. Most of the countries in the world, 192 states, are members of the UN. The UN oversees peacekeeping forces that help settle conflicts between member nations, but has no police force or military of its own to enforce its decisions.

    The UN has many departments and divisions to deal with specific issues, but the two main leadership bodies are the General Assembly and the Security Council. The General Assembly is composed of representatives from all member states, with each member getting one vote. The Security Council is responsible for maintaining peace among member nations, and is made up of five permanent members (United States, United Kingdom, Russia, France, and China) and 10 rotating members. The headquarters of the United Nations is in New York City.
