The Sanpoil (or San Poil) are a Native American people of the U.S. state of Washington. They are one of the Salish peoples and are one of the twelve members of the Confederated Tribes of the Colville Reservation. The name Sanpoil comes from the Okanagan [snpʕwílx], "gray as far as one can see". It has been folk-etymologized as coming from the French sans poil, "without fur". The Yakama people know the tribe as Hai-ai'-nlma or Ipoilq. The Sanpoil call themselves Nesilextcl'n, .n.selixtcl'n, probably meaning "Salish speaking," and N'pooh-le, a shortened form of the name. The Sanpoil had a semi-democratic system of government with various chiefs representing each community within the tribe. Heredity was not a requirement for chiefs. In later years, United States government officials began recognizing one chief at a time. The last four officially recognized chiefs of the San Poil Tribe were Que Que Tas (b. 1822-d.1905), his son Nespelem George (b. 1863-d. Jan. 29, 1929), Skolaskin, and Jim James. The mother of Que Que Tas was a woman chief who met Lewis and Clark on the great plateau when they came through on the Pacific Northwest Expedition. Ethnography Since the 17th century the Sanpoil flourished with a large number of villages along the Sanpoil River and Nespelem River, tributaries of the Columbia River Later, the tribe was placed on Sanpoil and Colville Reservations in Washington state. The San Poil Tribe was incorporated into the Colville Confederation by Executive Order from the President of the United States after strong recommendation from the Indian agents noting the San Poil's relatively peaceful nature toward others (especially European settlers). The Sanpoil are considered Interior Salish Native Americans, a designation that also includes the Okanagan, Sinixt, Lakes, Wenatchee, Nespelem, Spokan, Kalispel, Pend d'Oreilles, Coeur d'Alene, and Flathead peoples. Ross classifies Nespelem as one of the Okanagan tribes, while Winans classifies them as part of the Sanpoil. There is little cultural and linguistic difference between the San Poil and the Nespelem. In 1905, the United States Indian Office counted 324 Sanpoil and 41 Nespelem. In 1910, the Census counted 240 and 46. In 1913, after a survey, the Office of Indian Affairs counted 202 and 43. Language Sanpoil is a Salish language belonging to the inland division of Salishan languages typical of Plateau nations, and related most closely to Salishan languages' eastern section.
