Beyond the Aztec Frontier
Look at the Americas in the days before the European invasion. What you see are great empires in South and Central America, but, for the most part, a collection of thinly distributed and, in a political and material sense, less highly developed civilizations in North America. In what is now the southwestern region of the United States, the Anasazi (“Basket Makers”) evolved into the people of the Pueblo culture. For many years, these were the people who lived just beyond the Aztec frontier.
