Established February 4, 1864 with its county seat at Idaho City.

The Boise Basin, in which Idaho City lies, was one of the richest gold mining districts in the nation after the discovery of gold in 1862. More gold was pulled from this area than from the entire state of Alaska. At its peak in the 1860s and 1870s, Idaho City was, for a time, the largest city in the Northwest, it was this great influx of people that lead to the establishment of the Idaho Territory in 1863.
