AbstractAt present, the federal government is engaged in community-based self-government negotiations with a number of Indian bands and tribal groups across Canada with the objective of bringing about legislative arrangements for a limited form of self-government outside the Indian Act. An important part of these negotiations involves the federal government's promise to allow the incorporation of “customary or traditional structures,” where desired, into redesigned Indian governments. This article explores the difficulties confronting Indian leaders in their attempts to revitalize traditional governing practices within their respective communities. Through a comparison of traditional and contemporary governing practices in two plains Indian societies, the Blood and Peigan Nations, this article addresses the question of whether present Indian government, which represents an externally imposed form based on the Indian Act, has been institutionalized within these communities. If institutionalization has occurred, then a return to traditional governing practices, the author argues, is effectively precluded. After analyzing traditional and contemporary governing practices the author concludes that strong traditionalist orientations remain within these Indian communities, thus providing the opportunity for political revitalization.
