The fur trade in North Dakota had been well established by the time of 
        Lewis and Clark, both in Missouri River corridor and in the Red River 
        valley. In the Red River valley, the North West and Hudson’s Bay 
        Companies established posts near the Pembina River confluence, in the 
        Pembina Mountains, and in the Turtle Mountains. Some of the noteworthy 
        traders included Charles Jean Baptiste Chaboillez, Peter Grant, and Alexander 
        Henry, Jr. In the journals of Alexander Henry, Jr. mention of the Lewis 
        and Clark expeditions to the Mandan villages is noted.
        
Missouri River fur traders represented British, French, and Spanish interests. 
        Probably the first to establish active trade relations on the Missouri 
        was one Jacques D’Eglise, a Frenchmen who helped to reintroduce 
        Spanish interests in the area. Spain had contended that it was illegal 
        for any other power to trade on the upper Missouri, part of what the Spanish 
        Crown considered its territory. Others representing the Spanish included 
        James McKay and John Thomas Evans. Evans in particular visited villages 
        in 1796 which would, just eight years later, be among those Lewis and 
        Clark contacted. Among some of noteworthy traders were Rene Jesseaume, 
        who in 1794 established the North West Company trading post between the 
        Mandan and Hidatsa villages. Jesseaume was still in the area when the 
      Corps of Discovery arrived.
