1807 - Manuel Lisa establishes new fort

Fur trader, entrepreneur, Manuel Lisa

         Manuel Lisa's new fort was built for trade with the Crow and Blackfeet at a junction of the Yellowstone and Big Horn Rivers.  The Blackfeet were constantly hostile and involved in intrigues that turned the Arikara into enemies of the American traders.  As a result, the Arikara soon acquired a reputation as the most treacherous of the Missouri River tribes because they could not be intimidated by white traders.
