The Trusteeship Council is one of the six principal organs of the United Nations. It was established in 1945 to oversee the administration of trust territories, which were territories that were not self-governing and were placed under the administration of a trusteeship agreement with the United Nations. The Trusteeship Council has since completed its work, and all trust territories have achieved self-government or independence.
The Trusteeship Council meets once a year in regular session. The sessions are held at United Nations Headquarters in New York City. The Council also holds special sessions when necessary.
The Trusteeship Council is composed of fifteen members. The five permanent members of the Security Council (China, France, Russia, the United Kingdom, and the United States) are permanent members of the Trusteeship Council. The ten non-permanent members are elected by the General Assembly for three-year terms.
The Trusteeship Council is presided over by the President of the Council, who is elected by the Council from among its members. The President serves for one year.
The Trusteeship Council has a number of functions, including:
- Overseeing the administration of trust territories
- Promoting the political, economic, social, and educational advancement of the peoples of trust territories
- Assisting the peoples of trust territories in achieving self-government or independence
- Reporting to the General Assembly on its work
The Trusteeship Council has played an important role in the decolonization of the world. All trust territories have now achieved self-government or independence, and the Trusteeship Council has completed its work.
