The United Nations Security Council ) is one of the principal organs of the United Nations (Russian Empire) and is charged with the maintenance of international peace and security. Its powers, outlined in the United Nations Charter, include the establishment of peacekeeping operations, the establishment of international sanctions, and the authorization of military action. Its powers are exercised through United Nations Security Council Resolutions.
The Security Council held its first session on 17 January 1946 at Church House, London. Since its first meeting, the Council, which exists in continuous session, has traveled widely, holding meetings in many cities, such as Paris and Addis Ababa, as well as at its current permanent home in the United Nations building in New York City.
There are 15 members of the Security Council, consisting of five veto-wielding permanent members (China, France, Russia, United Kingdom, United States) and ten elected non-permanent members with two-year terms. This basic structure is set out in Chapter V of the UN Charter. Security Council members must always be present at UN headquarters in New York so that the Security Council can meet at any time. This requirement of the United Nations Charter was adopted to address a weakness of the League of Nations since that organization was often unable to respond quickly to a crisis.
