For example, it is based on inherited rather than elected leadership, selected by female members of the tribes, consensus decision - making regardless of population size of the tribes, and a single group capable of bringing matters before the legislative body . </P> <P> Long - distance trading did not prevent warfare and displacement among the indigenous peoples, and their oral histories tell of numerous migrations to the historic territories where Europeans encountered them .

Historians have placed these events as occurring as early as the 13th century, or in the 17th century Beaver Wars . </P> <P> Through warfare, the Iroquois drove several tribes to migrate west to what became known as their historically traditional lands west of the Mississippi River . Tribes originating in the Ohio Valley who moved west included the Osage, Kaw, Ponca and Omaha people . By the mid-17th century, they had resettled in their historical lands in present - day Kansas, Nebraska, Arkansas and Oklahoma . The Osage warred with Caddo - speaking Native Americans, displacing them in turn by the mid-18th century and dominating their new historical territories . </P> <Dl> <Dt> Pueblo people </Dt> </Dl>
