American Samoa is a United Statesterritory in the South Pacific Ocean. Settled as early as 1000 BC, Samoa was "discovered" by European explorers in the 18th century. International rivalries in the latter half of the 19th century were settled by an 1899 treaty in which Germany and the US divided the Samoan archipelago. The US formally occupied its portion - a smaller group of eastern islands with the excellent harbor of Pago Pago - the following year. (see History of Samoa for more.) The western islands are now the independent state of Samoa.

About 30 ethnic Samoans currently play in the NFL; it has been estimated that a Samoan male is 40 times more likely to play in the NFL than a non-Samoan American.
Persons born in American Samoa are United States nationals, but not United States citizens. This is virtually the only circumstance under which an individual would be one and not the other.
