Lah-Toh County, Idaho Territory
Lah-Toh County was created by the Idaho Territorial Legislature in 1864 with Coeur d'Alene as its county seat. The name is Nez Perce for "the place of pine trees and sestle". The county was abolished in 1867. The portion of the county located south of the present Latah County line was transferred to Nez Perce County while the portion of the county north of Latah County joined Kootenai County.
The county was re-established in 1888 with different boundaries as Latah County.
