Kootenai (kōtˈənāˌ) [key], group of Native North Americans who in the 18th cent. occupied the so-called Kootenai country (i.e., N Montana, N Idaho, and SE British Columbia). Their language is thought by some scholars to form a branch of the Algonquian-Wakashan linguistic stock, although others argue that it has not been definitely related to any known linguistic family (see Native American languages). The Upper Kootenai lived near the headwaters of the Columbia River, and the Lower Kootenai lived on the Lower Kootenai River. According to tradition the Kootenai once lived E of the Rocky Mts., but they were driven westward by their enemies the Blackfoot. Kootenai culture was essentially that of the Plateau area, but after the advent of the horse the Kootenai adopted many Plains area traits including a seasonal buffalo hunt. Contact with whites began early in the 19th cent., when the North West Company established Rocky Mountain House on the upper Saskatchewan River. In 1807 the same company opened the first trading post in Kootenai country. The Kootenai are related to the Salish, with whom they share the Flathead Reservation in NW Montana. Another group of Kootenai live on a reservation in Idaho. In 1990 there were 750 Kootenai and about 2,300 people of mixed Salish and Kootenai descent in the United States, as well as some 500 Kootenai in Canada. Their name is sometimes spelled Kootenay or Kutenai.
