The relation of the Government with the Plains Indians is of special importance in the history of the Southwest. Historians have been prone to generalize on this problem, and very little has been done on definite tribal relationships with the Government. The work of the government, not only of the United States, but also of Spain and France, in regard to Indian problems, should be definitely established. The problem was that of bringing the Indians from uncivilized wandering tribes to full fledged citizenship. This work is an attempt to portray Comanche life from early tribal conditions on down through the steps of government supervision. We find the tribal organization practically extinct and replaced by standards of civilization.
