William Wells Bent was a frontier trader and rancher in the American West, with forts in Colorado. He also acted as a mediator among the Cheyenne Nation, other Native American tribes and the expanding United States. With his brothers, Bent established a trade business along the Santa Fe Trail. In the early 1830s Bent built an adobe fort, called Bent's Fort, along the Arkansas River in present-day Colorado. Furs, horses and other goods were traded for food and other household goods by travelers along the Santa Fe trail, fur-trappers, and local Mexican and Native American people. Bent negotiated a peace among the many Plains tribes north and south of the Arkansas River, as well as between the Native American and the United States government.

Bent's Old Fort is a fort located in Otero County in southeastern Colorado, United States. A company owned by Charles Bent and William Bent and Ceran St. Vrain built the fort in 1833 to trade with Southern Cheyenne and Arapaho Plains Indians and trappers for buffalo robes. For much of its 16-year history, the fort was the only major white American permanent settlement on the Santa Fe Trail between Missouri and the Mexican settlements. It was destroyed in 1849.
