This group of natives in North America were indigenous to the Interior Plains, historically nomadic, and relied on bison hunting.
Bison hunting Bison hunting (hunting of the American bison, also commonly known as the American buffalo) was an activity fundamental to the economy and society of the Plains Indians peoples who inhabited the vast grasslands on the Interior Plains of North America, prior to the animal's near-extinction in the late nineteenth century. The species' dramatic decline was the result of habitat loss due to the expansion of ranching and farming in western North America, industrial-scale hunting practised by non-indigenous hunters, increased indigenous hunting pressure due to non-indigenous demand for bison hides and meat, and even cases of deliberate policy by settler governments to destroy the food source of the native Indian peoples during times of conflict. Bison were first hunted for their meat, but now they are hunted for sport.
Comanche history Forming a part of the Eastern Shoshone linguistic group in southeastern Wyoming who moved on to the buffalo Plains around AD 1500 (based on glottochronological estimations), proto-Comanche groups split off and moved south some time before AD 1700. The Shoshone migration to the Great Plains was apparently triggered by the Little Ice Age, which allowed bison herds to grow in population. It is not clear why the proto-Comanches broke away from the main Plains Shoshones and migrated south. That move may have been inspired as much by the desire for Spanish horses released by the Pueblo Revolt of 1680 as by pressures from other groups drawn to the Plains by the changing environment.
