Northern Mariana Islands
The Commonwealth of the Northern Mariana Islands (CMMI) derives from the United Nations' Trust Territory of the Pacific Islands (TTPI), created in 1947, and administered by the United States. As of 1990, the TTPI was dissolved and a local constitution developed.
The Marianas constitution provides for a governor, a lieutenant governor, a bicameral legislature (18 members in the House of Representatives and 9 members in the Senate), and a local court system including Superior and Supreme Courts. There is a U.S. District Court for the Northern Marianas Islands, and, as of 2008, the CMMI has a non-voting delegate in the U.S. Congress.
It is three-hundred mile archipelago consisting of 14 islands, with a total land area of 183.5 square miles, with the population primarily on Saipan, Rota and Tinian. The northern, largely uninhabited islands are Farallon de Medinilla, Anatahan, Sariguan, Gudgeon, Alamagan, Pagan, Agrihan, Asuncion, Maug Islands, and Farallon de Pajaro.
Saipan was a major Japanese base in the Second World War, which the Japanese considered the anchor of their inner defensive perimeter. The U.S. victory at the Battle of Saipan led to the fall of the Tojo government and the beginnings of a peace faction.
The U.S. had an airbase on Tinian, from which the 509th Bomb Group carried out the nuclear attacks against Japan.
