This work answers the hypothetical question: What would the Americas be like today - politically, economically, culturally - if Columbus and the Europeans had never found them, and how would American peoples interact with the world's other societies? It assumes that Columbus did not embark from Spain in 1492 and that no Europeans found or settled the New World afterward, leaving the peoples of the two American continents free to follow the natural course of their Native lives. The Americas That Might Have Been is a professional but layman-accessible, fact-based, nonfiction account of the major Native American political states that were thriving in the New World in 1492. Granberry considers a contemporary New World in which the glories of Aztec Mexico, Maya Middle America, and Inca Peru survived intact. He imagines the roles that the Iroquois Confederacy of the American Northeast, the powerful city-states along the Mississippi River in the Midwest and Southeast, the Navajo Nation and the Pueblo culture of the Southwest, the Eskimo Nation in the Far North, and the Taino Arawak chiefdoms of the Caribbean would play in American and world politics in the 21st Century. Following a critical examination of the data using empirical archaeology, linguistics, and ethnohistory, Granberry presents a reasoned and compelling discussion of native cultures and the paths they would have logically taken over the past five centuries. He reveals the spectacular futures these brilliant pre-Columbian societies might have had, if not for one epochal meeting that set off a chain of events so overwhelming to them that the course of human history was forever changed.
