History

In July 1858, gold along the South Platte River in Arapahoe County, Kansas Territory discovered. This discovery triggered the Pikes Peak Gold Rush. Many residents in the mining region felt disconnected from the remote territorial governments of Kansas and Nebraska, so that on October 24, 1859 voted to form their own Jefferson Territory. In the following months, the General Assembly approved the Jefferson Territory to organize 12 counties: Arrappahoe County, Cheyenne County, El Paso County, Fountain County, Heele County, Jackson County, Jefferson County, Mountain County, North County, Park County, Saratoga County and St. Vrain County. The Cheyenne County was in the field, which today includes the city of Cheyenne, Wyoming. The county was named after the Cheyenne Nation, an American Indian people who lived in this area, named.

The Jefferson Territory never received federal support. On February 28, 1861, the Colorado Territory was organized on 25 July 1868, the Wyoming Territory.
