Roxanne Dunbar-Ortiz grew up in rural Oklahoma, the daughter of a tenant farmer and part-Indian mother. She has been active in the international Indigenous movement for more than four decades and is known for her lifelong commitment to national and international social justice issues. After receiving her PhD in history at the University of California at Los Angeles, she taught in the newly established Native American Studies Program at California State University, Hayward, and helped found the Departments of Ethnic Studies and Women’s Studies.
Her 1977 book The Great Sioux Nation was the fundamental document at the first international conference on Indigenous peoples of the Americas, held at the United Nations’ headquarters in Geneva. Dunbar-Ortiz is the author or editor of seven other books, including Red Dirt: Growing Up Okie, and An Indigenous Peoples’ History of the United States. Her forthcoming book is titled Loaded and is a history of gun culture and the second amendment.
