The United Nations is an Intergovernmental Organization with a mission to solve Conflicts, provide Human Rights, and promote Democracy around the World.
The Organization was formed during the end of World War 2 in 1945, since then, in the Post-World War 2, the UN played an important role in the Cold War, opposing the Severe Expansion of the Soviet Union and their allies. When the Cold War was over under the Fall of the Soviet Union and the United States surviving in 1991, the United Nations had a new role, promoting Peace and Human Rights under the Leadership of the United States. In the September 11 Attacks and the War on Terror, the UN had an even more important role.
The Headquarters of the United Nations is New York City, the largest city in the United States that was once the Capital of the United States until Washington, D.C. arrived. The United Nations is governed by the General Assembly, and the General-Secretary.
