Empire of the Summer Moon: Quanah Parker and the Rise and Fall of the Comanches, the Most Powerful Indian Tribe in American History

by S.C. Gwynne

They would have to reorder their entire social structure around a set of values and principles that were still largely unimaginable to them. The Comanches and Kiowas were to share a 2.9-million-acre reservation in what is now southwestern Oklahoma, north and east of the Red River and its north fork, south of the Washita, and west of the 98th meridian. This was actually very good land, huntable and arable and with decent water sources, and it was in traditional Comanche territory and included Medicine Bluffs and other sacred sites. But it was a tiny fraction of Comancheria, which at its peak held nearly 200 million acres. Nor did it include by far the richest of the old hunting grounds, the Texas bison plains.
