The United Nations was established in 1945 with 51 founding member countries committed to maintaining international peace and security through cooperation. The UN has four basic principles: maintaining peace, developing friendly relations between nations, solving international problems, and promoting human rights. While not a world government, the UN provides a forum for international cooperation and decision making between its 192 member states. The main UN bodies are the General Assembly, Security Council, Economic and Social Council, Trusteeship Council, Secretariat, and International Court of Justice.
