About This Place
Idaho City is a city in and the county seat of Boise County, Idaho, United States, located about 36 miles (58 km) northeast of Boise. The population was 458 at the 2000 census.
Idaho City is part of the Boise City–Nampa, Idaho Metropolitan Statistical Area.
Idaho City was founded in December 1862 as "Bannock" (sometimes given as "West Bannock"), amidst the Boise Basin gold rush during the Civil War, the largest since the California gold rush a dozen years earlier. Near the confluence of Elk and Mores Creeks, its plentiful water supply allowed it to outgrow the other nearby camps in the basin, such as Placerville, Pioneerville, and Centerville. As its population swelled, the new Idaho Territorial legislature changed the town's name to "Idaho City," to avoid confusion with Bannack, Montana, in present-day Beaverhead County, the southwestern corner of Montana.
