Between 1873 and 1932, Indian policy on the prairies was the responsibility of federal government appointees known as Indian Commissioners. Charged with incorporating Native society into the apparatus of the emergent state, these officials directed a complex configuration of measures that included treaties, the Indian Act, schools, agriculture, and to some degree, missionary activity. In this study, Brian Titley constructs critical biographical portraits of the six Indian Commissioners, examining their successes and failures in confronting the challenges of a remarkable period in Canada's history.
