Latah County, Idaho: History
=== Settlement ===
European-American settlement of the Palouse commenced in 1871. Development of population centers at Genesee and Moscow are the earliest followed by Juliaetta and Kendrick in the 1880s. The railroad's arrival in Moscow in 1885 led to its development as the primary population center of the county. The establishment of the University of Idaho at Moscow in 1889 also was significant in the city's continued growth. Settlement of Troy commenced in 1895 with Bovill being first settled by Lord Hugh Bovill in 1899. Construction of a railroad from Moscow to Bovill was completed in 1907 with the town of Deary developing in that year on the railroad. Potlatch was settled as a company town in 1905.
Moscow first shows in the 1880 census with a population of 76. It was incorporated as a village in 1887. Genesee was established as a town in 1889. Julieatta, Kendrick, and Troy were established as towns by the 1900 Census, with each incorporating as a village prior to 1910. Bovill and Deary were incorporated as villages prior to 1920. Potlatch and Onaway remained unincorporated as late as 1960. They were returned at the 1950 Census as a single unincorporated area.
The Idaho Territorial Legislature established the counties of Lah-Toh and Kootenai on December 22, 1864. Lah-Toh contained all of northern Idaho west of Shoshone County between the Clearwater River and 48° north latitude. Coeur d'Alene was named the county seat of Lah-Toh County. The legislature was well aware that settlement was lacking in the area to support a county government and established that the Governor could organize the county commission upon receipt of a petition from fifty residents. On January 9, 1867, the Fourth Idaho Legislature repealed the act creating the two counties, established the northern line of Nez Perce County to coincide with the present northern line of Latah County, and placed the remaining portion of Lah-Toh within the boundary of Kootenai County. Unaware of Lah-Toh's abolishment, residents of Moscow attempted to organize the county of Lah-Toh in 1878. Initially, the Governor granted the request, but later informed the residents that they were actually located within the boundary of Nez Perce County. The Idaho Territorial Legislature failed to address creation of a county for the residents of Moscow. As a result, Fred T. Dubois successfully petitioned on their behalf for the United States Congress to create the county. On May 14, 1888, Latah County with its seat at Moscow came into existence as the first and only U.S. county created by the United States Congress.
