History of Wyoming
The UP reached the town of Cheyenne, which later became the state capital, in 1867. The railroad eventually spanned the entire state, boosting the population, and creating some of Wyoming's largest cities, such as Laramie, Rock Springs and Evanston. The railroad needed coal, which was discovered in quantity in the southwestern part of the state, especially around Rock Springs. In 1885, a murderous riot known as the Rock Springs Massacre broke out when white miners drove out Chinese miners employed by the Union Pacific Coal Company in Rock Springs.
Wyoming State Capitol
The construction of the capitol began prior to Wyoming gaining statehood. Cheyenne was born in 1867 in the path of the transcontinental railroad, when the Union Pacific crews arrived to lay tracks westward. Cheyenne soon laid claim to a higher status than older Wyoming settlements such as those at Fort Laramie, Fort Bridger, and the mining town of South Pass City, changing Cheyenne from a village to a city in a matter of months. The seat of the new Territorial government was established in Cheyenne in 1869.
