Chapter XI of the United Nations Charter defines a non-self-governing territory (NSGT) as a territory "whose people have not yet attained a full measure of self-government". Chapter XI of the UN Charter also includes a "Declaration on Non-Self-Governing Territories" that the interests of the occupants of dependent territories are paramount and requires member states of the United Nations in control of such territories to submit annual information reports concerning the development of those territories. Since 1946, the UNGA has maintained a list of non-self governing territories under member states' control. Since its inception, dozens of territories have been removed from the list, typically when they attained independence or internal self-government, while other territories have been added as new administering powers joined the United Nations or the UN General Assembly (UNGA) reassessed their status.
Since 1961 the list has been maintained by the Special Committee on Decolonization.
Chapter XI of the UN Charter contains a Declaration Concerning Non-Self-Governing Territories. Article 73(e) requires UN member states to report to the United Nations annually on the development of NSGTs under their control. From the initial reports provided by eight member states (Australia, Belgium, Denmark, France, the Netherlands, New Zealand, the United Kingdom and the United States), a list was compiled in 1946 listing 72 NSGTs. In several instances, administering powers were later allowed to remove dependent territories from the list, either unilaterally (as in the case of French overseas territories such as French Polynesia), or by a vote of the General Assembly (as in the cases of Puerto Rico, Greenland, the Netherlands Antilles and Suriname).
The list draws its origins from the period of colonialism and the Charter's concept of non-self-governing territories. As an increasing number of formerly colonized countries became UN members, the General Assembly increasingly asserted its authority to place additional territories on the list and repeatedly declared that only the General Assembly had the authority to authorize a territory's being removed from the list upon attainment of any status other than full independence. For example, when Portugal joined the United Nations it contended that it did not control any non-self-governing territory, claiming that areas such as Angola and Mozambique were an integral part of the Portuguese state, but the General Assembly rejected this position. Similarly, Western Sahara was added in 1963 when it was a Spanish colony. As with Namibia, which was seen, due to its former status as a League of Nations mandate territory, as a vestige of German colonial legacy in Africa, until it was removed in 1990 upon its independence. A set of criteria for determining whether a territory is to be considered "non-self-governing" was established in General Assembly Resolution 1541 (XV) of 1960. Also in 1960, the General Assembly adopted , promulgating the "Declaration on the Granting of Independence to Colonial Countries and Peoples", which declared that all remaining non-self-governing territories and trust territories were entitled to self-determination and independence. The following year, the General Assembly established the Special Committee on the Situation with Regard to the Implementation of the Declaration on the Granting of Independence to Colonial Countries and Peoples (sometimes referred to as the Special Committee on Decolonization, or the "Committee of 24" because for much of its history the committee was composed of 24 members), which reviews the situation in non-self-governing territories each year and reports to the General Assembly. A revised list in 1963 listed 64 NSGTs.
The following 17 territories are currently included in the list.
