Politics of American Samoa takes place in a framework of a presidential representative democratic dependency, whereby the governor is the head of government, and of a pluriform multi-party system. American Samoa is an unincorporated and unorganized territory of the United States, administered by the Office of Insular Affairs, U.S. Department of the Interior. Its constitution was ratified in 1966 and came into effect in 1967. Executive power is discharged by the governor and the lieutenant governor. Legislative power is vested in the two chambers of the legislature. The party system is based on the United States party system. The judiciary is independent of the executive and the legislature.
There is also the traditional village politics of the Samoan Islands, the fa'amataicode: smo promoted to code: sm and the faʻa Sāmoacode: smo promoted to code: sm , which continues in American Samoa and in independent Samoa, and which interacts across these current boundaries. The faʻa Sāmoacode: smo promoted to code: sm is the language and customs, and the fa'amataicode: smo promoted to code: sm the protocols of the fonocode: smo promoted to code: sm (council) and the chiefly system. The fa'amataicode: smo promoted to code: sm and the fonocode: smo promoted to code: sm take place at all levels of the Samoan body politic, from the family, to the village, to the region, to national matters. The mataicode: smo promoted to code: sm (chiefs) are elected by consensus within the fonocode: smo promoted to code: sm of the extended family and village(s) concerned. The mataicode: smo promoted to code: sm and the fonocode: smo promoted to code: sm (which is itself made of mataicode: smo promoted to code: sm ) decide on distribution of family exchanges and tenancy of communal lands. The majority of lands in American Samoa and independent Samoa are communal. A mataicode: smo promoted to code: sm can represent a small family group or a great extended family that reaches across islands, and to both American Samoa and independent Samoa.
