United Nations Security Council

The Security Council held its first session on 17 January 1946 at Church House, Westminster, London. Since its first meeting, the Security Council has taken permanent residence at the United Nations Headquarters in New York City. It also travelled to many cities, holding sessions in Addis Ababa, Ethiopia, in 1972, in Panama City, Panama, and in Geneva, Switzerland, in 1990.

A representative of each of its members must be present at all times at UN Headquarters so that the Security Council can meet at any time as the need arises.


Under the United Nations Charter, the functions and powers of the Security Council are:

  • to maintain international peace and security in accordance with the principles and purposes of the United Nations;
  • to investigate any dispute or situation which might lead to international friction;
  • to recommend methods of adjusting such disputes or the terms of settlement;
  • to formulate plans for the establishment of a system to regulate armaments;
  • to determine the existence of a threat to the peace or act of aggression and to recommend what action should be taken;
  • to call on Members to apply economic sanctions and other measures not involving the use of force to prevent or stop aggression;
  • to take military action against an aggressor;
  • to recommend the admission of new Members;
  • to exercise the trusteeship functions of the United Nations in “strategic areas”;
  • to recommend to the General Assembly the appointment of the Secretary-General and, together with the Assembly, to elect the Judges of the International Court of Justice.

The Council is composed of 15 Members:
Five permanent members: China, France, Russian Federation, the United Kingdom, and the United States, and ten non-permanent members elected for two-year terms by the General Assembly (with end of term year).
