Two centuries ago, the fierce winds of change were sweeping through the Middle Missouri Valley. French, Spanish and then American traders and settlers had begun pouring in. In the midst of this time of tumult and transition, five chiefs rose up to lead their peoples: Omaha Chief Big Elk, the Pottawatamie/Ottawa/Chippewa Tribe's Captain Billy Caldwell, Ioway Chief Wangewaha (called Hard Heart), Pawnee Brave Petalesharo and Ponca Chief Standing Bear. Historian Gail Holmes tells the story of their leadership as the land was redefined beneath them.
