Fort Union was built in 1828 near the confluence of the Yellowstone
and Missouri Rivers in what is today northwest North Dakota. Established
first as Fort Floyd, the site became the flagship fur trade operation
for the American Fur Company of St. Louis. By the mid-1830's, the fort
was a major trade site, attracting a wide number of Native American
groups such as the Assiniboine, Blackfeet, various Dakota bands, as
well as the Mandan, and Hidatsa. Fort Union was closed as a trade operation
in 1866.
