Oklahoma is home to nearly forty American Indian tribes and includes the largest Native population of any state. As a result, many Americans think of the state as “Indian Country.” In 2009, Blue Clark, an enrolled member of the Muscogee (Creek) Nation, produced an invaluable reference for information on the state’s Native peoples. Now, building on the success of the first edition, this revised guide offers an up-to-date survey of the diverse nations that make up Oklahoma’s Indian Country. Since publication of the first edition more than a decade ago, much has changed across Indian Country—and more is known about its history and culture. Drawing from both scholarly literature and Native oral sources, Clark incorporates the most recent archaeological and anthropological research to provide insights into each individual tribe dating back to prehistoric times. Today, the thirty-nine federally recognized tribes of Oklahoma continue to make advances in the areas of tribal governance, commerce, and all forms of arts and literature. This new edition encompasses the expansive range of tribal actions and interests in the state, including the rise of Native nation casino operations and nongaming industries, and the establishment of new museums and cultural attractions. In keeping with the user-friendly format of the original edition, this book provides readers with the unique story of each tribe, presented in alphabetical order, from the Alabama-Quassartes to the Yuchis. Each entry contains a complete statistical and narrative summary of the tribe, covering everything from origin tales to contemporary ceremonies and tribal businesses. The entries also include tribal websites, suggested readings, and photographs depicting visitor sites, events, and prominent tribal personages.
