Unkpatina
Unkpatina is a name for the Hunkpatina, or Lower Yanktonai, a division of the Dakota people. Their country lay among the northern Plains and the Missouri River, within a wider world of Dakota communities whose relationships were maintained by kinship and diplomacy. Like other Yanktonai, they hunted bison and moved across the prairie. In the early nineteenth century American traders and expeditions encountered Yanktonai people as the fur trade expanded along the Missouri.
