The nameSanpoil comes from theOkanagan[snpʕwílx], "gray as far as one can see". It has beenfolk-etymologized as coming from the Frenchsans poil, "without fur".[3] The Yakama people know the tribe asHai-ai'-nlma orIpoilq. The Sanpoil call themselvesNesilextcl'n,.n.selixtcl'n, probably meaning "Salish speaking," andN'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. Chiefs were not hereditary. In the 19th and early 20th centuries, United States government officials began recognizing one chief at a time.
The Sanpoil 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 Sanpoil's relatively peaceful nature toward others, notably Euro-American settlers.
