In January 1958, teenagers Charles Starkweather and Caril Ann Fugate went on a 10-victim killing spree that began in Nebraska and ended near Douglas, Wyo., after a high-speed chase through the middle of town. Starkweather was later executed in Nebraska, and Fugate was paroled after 18 years.

In 1850, the U.S. Congress authorized a conference to persuade Plains Indian tribes to live and hunt within newly designated, separate territories, and to accept payment for the damage caused by emigrants crossing their lands. The conference in September 1851 drew 10,000 Indians to the confluence of Horse Creek and the North Platte River, 30 miles east of Fort Laramie. The treaty that was signed there, the Horse Creek Treaty of 1851, permanently changed the terms of Indian-white relations on the northern Great Plains.
