For context, Robbie Ethridge traces the long history of the Muscogee (Creek) Nation from its inception in present-day Georgia and Alabama in the seventeenth century; through the tribe's rise to regional prominence in the colonial era, the tumultuous years of Indian Removal, and the Civil War and allotment; and into its resurgence in Oklahoma in the twentieth and twenty-first centuries. Against this historical background, Robert J. Miller considers McGirt v. Oklahoma, examining important related cases, precedents that informed the Court's decision, and future ramifications--legal, civil, regulatory, and practical--for the Muscogee (Creek) Nation, federal Indian law, the United States, the state of Oklahoma, and Indian nations in Oklahoma and elsewhere. Their work clarifies the stakes of a decision that, while long overdue, raises numerous complex issues profoundly affecting federal, state, and tribal relations and law--and will continue to do so for the foreseeable future.
