Coeur d'Alene (kûrdəlānˈ) [key], city (1990 pop. 24,563), seat of Kootenai co., N Idaho, near the Wash. line; inc. 1907. It is a tourist and lumbering center situated on Coeur d'Alene Lake W of the Coeur d'Alene Mts.—the gateway to a summer and winter resort area. The city has lumber mills and meat-processing plants. Fort Coeur d'Alene (later Fort Sherman) was established in 1876. The city (named after the Native American tribe) grew around the fort with the discovery (1883) of rich silver, lead, and zinc lodes and the subsequent mining boom. For the tumultuous early history of the city, see Western Federation of Miners. The city is the headquarters of Coeur d'Alene National Forest.
