First County Seat
The first county seat was Sin-na-ac-qua-teen, a trading post located on the Clark Fork River (it was subsequently relocated to Rathdrum and later, in 1907, to Coeur d'Alene, where it remains today). Fort Coeur d'Alene (later renamed to Fort Sherman) was established in 1878; Coeur d'Alene City developed near the edge of the fort and within a few years had become a supply point and navigation hub for the mining and timber industry. Coeur d'Alene's importance as Kootenai County's center was reinforced when voters moved the county seat to Coeur d'Alene in 1908.

Six large lumber mills were located in or near Coeur d'Alene, and the city boasted 4 banks, 5 hotels, 9 churches, 4 grade schools and a high school, a movie theater, and 2 telephone systems. Four railroads served the city: the Northern Pacific, the Inland Empire Railroad electric line, the Milwaukee Road, and the Spokane International. Coeur d'Alene's major industries were timber, tourism and agriculture. By the early 1930s, Coeur d'Alene was Kootenai County's economic and social center. The City served 4 major rail lines and boasted 6 major lumber mills. Harrison was also a popular lumber center for the mining district. Bayview claimed four lime quarries and five lime processing kilns.
