An exploration of Indigenous cosmology and history in North America While Western accounts of North American history traditionally start with European colonization, Indigenous histories of North America–or Turtle Island–stretch back millennia. Drawing on comparative analysis, firsthand Indigenous accounts, extensive historical writings, and his own experience, Omaha Tribal member, Cherokee Citizen, and teacher Taylor Keen presents a comprehensive re-imagining of the ancient and more recent history of this continent's oldest cultures. Examining the complexities and commonalities of Indigenous legends and creation myths, Keen reveals shared oral traditions across much of North America, including among the Algonquin, Athabascan, Sioux, Omaha, Ponca, Osage, Quapaw, and Kaw tribes. He explores the history of Cahokia, the Mississippian Mound Builder Empire of 1050-1300 CE, told through the dramatic story of Honga, a Native leader who is building a dynastic empire within the third largest city in the world at the time. He examines ancient earthen works and ceremonial sites of Turtle Island, revealing the Indigenous cosmology, sacred mathematics, and archaeoastronomy encoded in these places that artfully blend the movements of the sun, moon, and stars into the physical landscape. Challenging the mainstream historical consensus, Keen presents an Indigenous revisionist history regarding Thomas Jefferson, expansionist doctrine, and Manifest Destiny. He reveals how, despite being displaced as the United States colonized westward, the Native peoples maintained their vision of an intrinsically shared humanity and the environmental responsibility found at the core of Indigenous mythology. Building off a deep personal connection to the history and mythology of the First Peoples of the Americas, Taylor Keen helps to rediscover and give renewed voice to the immemorial cultures of Turtle Island, revealing an alternative vision of the continent's geography and the significance of our past and future presence here.
