Bent's Fort was a landmark of the American frontier, a huge private fort on the upper Arkansas River in present southeastern Colorado. Established by the adventurers Charles and William Bent, it stood until 1849 as the center of the Indian trade of the central plains. David Lavender's chronicle of these men and their part in the opening of the West has been conceded a place beside the works of Parkman and Prescott.

From about 1830 to 1849, Bent's Old Fort, located in present-day Colorado, was the largest trading post in the Southwest and the mountain-plains region. Although the raw enterprise and improvisation that characterized the American westward movement seem to have little to do with ritual, Douglas Comer argues that the fort grew and prospered because of ritual and that ritual shaped the subsequent history of the region to an astonishing extent.
