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.
