United Nations System

The United Nations Office at Geneva (Switzerland) is the second biggest UN centre, after the United Nations Headquarters (New York City).

The United Nations System consists of the United Nations' six principal bodies: the General Assembly, the Security Council, the Economic and Social Council (ECOSOC), the Trusteeship Council, the International Court of Justice (ICJ), the Secretariat, and the specialized agencies and related organizations. The UN System includes subsidiary bodies such as the separately administered funds and programmes, research and training institutes, and other subsidiary entities. Some of these organizations predate the founding of the United Nations in 1945 and were inherited after the dissolution of the League of Nations.
