After the
United Nations was founded in 1945, the League of Nations was disbanded; all but one of the mandated territories became
United Nations trust territories, a roughly equivalent status. In each case, the colonial power that held the mandate on each territory became the administering power of the trusteeship, except the
Empire of Japan, which, having been defeated in World War II, lost its mandate over the South Pacific islands. These islands became a "strategic trust territory" under U.S. administration known as the
Trust Territory of the Pacific Islands. The sole exception to the transformation of the League of Nations mandates into UN trusteeships was
South Africa and its mandated territory,
South West Africa. Rather than placing South West Africa under trusteeship, as with other former mandates, South Africa proposed
annexation, a proposition rejected by the
UN General Assembly. Despite South Africa's resistance, the
International Court of Justice affirmed that South Africa remained subject to international obligations under the South West Africa mandate. Eventually, in 1990, the mandated territory, now
Namibia, gained independence, culminating from the
Tripartite Accords and the resolution of the
South African Border War — a prolonged guerrilla conflict against the
apartheid regime that lasted from 1966 until 1990. Nearly all the former League of Nations mandates had become
sovereign states by 1990, including all of the former UN trust territories except a few successor entities of the gradually dismembered Trust Territory of the Pacific Islands (formerly Japan's South Pacific Trust Mandate). These exceptions include the
Northern Mariana Islands, which is a
commonwealth in
political union with the U.S., with the status of
unincorporated organised territory. The Northern Mariana Islands elects its own
governor to serve as territorial
head of government. Still, it remains a U.S. territory with its
head of state being the President of the United States and
federal funds to the commonwealth administered by the
Office of Insular Affairs of the
U.S. Department of the Interior. Remnant
Micronesia and the
Marshall Islands, the heirs of the last territories of the Trust, attained final independence on 22 December 1990. (The UN Security Council ratified the termination of trusteeship, effectively dissolving the trusteeship status, on 10 July 1987.) The
Republic of Palau, split off from the
Federated States of Micronesia, became the last to gain its independence effectively, on 1 October 1994. ==See also==
