This doctoral thesis explores the uniqueness of Cree spirituality and law, based in part on oral histories and on Euro-Canadian literal evidence, specifically the multi-volumes of the Jesuit Relations and the thousands of Hudson’s Bay Company manuscripts that re-enforce insights into this Aboriginal governing system. Taken together, the oral and literal primary evidences will define how spirituality and law pre-existed colonisation and are manifested within self-governing institutions currently pursued by First Nations. The purpose is to understand better Cree spirituality and law as captured in Cree self-government models. This Aboriginal legal history contains and studies a plan of action for future self-governance based on inherent Aboriginal legal traditions and jurisprudence.
