Idaho Counties

There are forty-four Counties in Idaho. When Idaho became a territory in March, 1863, there were four Counties in existence: Boise, Idaho, Nez Perce and Shoshone. By the time Idaho became a state, there were 15 counties. The rest of the 44 Counties came into existence during the 30 years after Idaho became a state. Two of the former counties disappeared during this time. Alturas, which was created in 1864, was later divided into the many counties now found in central Idaho. Logan County was only in existence for six years, from 1889 to 1895. It was combined with Alturas to form Blaine County and Lincoln County, which was formed just two weeks after Logan lost its identity.
