Beginning with Native American activism in the 1960's and bolstered by the Indian Self Determination Act of 1975, tribes have been actively attempting in recent decades to increase tribal sovereignty and self-determination and revitalize tribal communities. One way they are doing this at Rocky Boy's Reservation in North Central Montana, is by taking control of the production of tribal narratives through institutions like the tribe's Internal Review Board and the completion of the first tribal history written completely by tribal members (2008). Another way is by looking back at the history of past researchers to the reservation and having important dialogues about the impacts and legacies of those researchers' work with the community. Out of this dialogue an "oral tradition" has emerged at Rocky Boy centering largely on Frank Bird Linderman (1869-1938) and Verne Dusenberry (1906-1966). These two researchers are often remembered very differently by tribal members: Linderman emerges as a hero due to his political aid for the Chippewa Cree in helping them acquire a reservation homeland, while Dusenberry more often serves as a representative of the troubled relationship between researchers and the tribe in the past. This dissertation examines the creation of historical narratives about Rocky Boy's Chippewa Cree, focusing on the effects of "contests" over cultural authority between key researchers to the reservation and tribal leaders in the making of those narratives. This dissertation makes a comparative analysis of the similarities and differences between the two researchers' claims to cultural authority by returning them to the contexts of their relationships with Chippewa Cree, and the stories and legacies that emerged around their work on the reservation. It explores the responses of tribal leaders to Linderman and Dusenberry and attempts by Chippewa Cree leaders (Little Bear, Big Rock, Rocky Boy, and Four Souls) to recontextualize and reclaim cultural authority and tribal historical narratives in their interactions with these researchers. By making these comparisons, this dissertation examines the ongoing effects these battles over cultural authority have had on tribal self-determination and revitalization efforts both past and present. Two of four chapters detail the lives and textual works of Frank Bird Linderman and Verne Dusenberry. These two men serve as a nexus point for the complex, interwoven and historically-layered "contexts" and "contests" over authority--both past and present, inter-culturally and intra-tribally, as writing and material forms, between outsiders and the living reservation that are the focus of this dissertation. This dissertation intervenes into previous histories written about Rocky Boy that have largely failed to recognize how complexly intertwined and often shared the processes of creating histories about the Rocky Boy's Reservation have been between outside researchers, tribal leaders and the reservation community. It also intercedes in the ongoing dialogue and debate about the role of researchers, cultural authority and protocols and tribal history in tribal revitalization and self-determination for the tribe.
