Pah-Ute County, Arizona Territory

The majority of the territory is now in Clark County, Nevada, which includes the city of Las Vegas.

Created to meet the needs of a rapidly growing population of farmers along the Colorado River, the county seat was initially Callville.

[2][3][4] The county seat was moved to the Mormon community of St. Thomas on October 1, 1867.

[5] The Arizona Territory lodged multiple protests with Congress and attempted for several years to have the transfer reversed, but was unable to overturn the change of possession.

During this time, Pah-Ute county continued to have representation in the Arizona Territorial Legislature through 1868.
