The organ of the United Nations Organization responsible for the former colonies of defeated world war ll powers is the Trusteeship Council. The Trusteeship Council was established by the United Nations in 1945 to oversee the administration of trust territories and to promote their development towards self-government or independence. These trust territories were territories that were formerly part of the defeated powers of World War II, which were placed under the control of the United Nations. The Trusteeship Council was responsible for overseeing the administration of these territories, providing assistance in economic and social development, and ensuring that they were prepared for self-government or independence. The Trusteeship Council suspended its operations in 1994 after the last trust territory, Palau, became independent. Therefore, the Trusteeship Council was responsible for overseeing the former colonies of the defeated powers of World War II under the United Nations.
