      The Missouri were a sedentary hunter/farmer nation but became nomadic buffalo hunters in the summer.  They were closely associated and related to the Otoe tribe and located on the Missouri River at the mouth of the Grand River upon White arrival, but soon moved to the lower Platte and neighboring Missouri Rivers.
     Tradition states that they were once one nation which included the Iowa, Missouria, and Winnebago .  They first split from the Winnebago, and later from the Iowa.  A later fission from the Otoe resulted from a quarrel between two chiefs over the seduction of one's daughter by the son of the other.  Linguistic evidence concurs with the order and timing of these events.
      White pressure and inter-tribal wars forced numerous relocations and large population losses in the 19th century.  They finally rejoined their closest relatives the Otoe.
