Abstract: Sharlot Hall was an author, poet, historian, booster, ranch woman, presidential elector, clubwoman, and development advocate for the territory and subsequently state of Arizona at the turn of the twentieth century. As an influential public figure regionally and nationally, she helped to shape a collective understanding of Arizona’s geography, past, and its future potential. Examined holistically, Hall’s work is best understood within a settler colonial context. She described a backdrop of an empty, untamed wilderness, which she then peopled with peaceful, hardworking, law-abiding Anglo settlers to the region in her historical writing, preservation, and educational work. When combined with a carefully curated, timeless depiction of Native Americans and her fervent advocacy for Arizona’s full and equal inclusion into the nation, Hall’s narratives and actions lay the groundwork for the naturalization and justification of a settler colonialist project.
