Gods of Thunder: How Climate Change, Travel, and Spirituality Reshaped Precolonial America

A sweeping account of Medieval North America when Indigenous peoples confronted climate change.

Few Americans today are aware of one of the most consequential periods in ancient North American history-the Medieval Warm Period of seven to twelve centuries ago (AD 800-1300 CE). On every page of this book, readers will be led down the same paths walked by Indigenous people a millennium ago, some
trod by Spanish conquistadors just a few centuries later. The book will follow the footsteps of priests, pilgrims, traders, and farmers who took great journeys, made remarkable pilgrimages, and migrated long distances to new lands.

Along the way, readers will discover a new history of a continent that, like today, was being shaped by climate change-or controlled by ancient gods of wind and water. Through such elemental powers, the history of Medieval America was a physical narrative, a long-term natural and cultural experience
in which Native people were entwined long before Christopher Columbus arrived or Hernan Cortes conquered the Aztecs.

The book's dozen chapters cover a lot of ground, focusing on some remarkable parallels between pre-contact American civilizations separated by a thousand miles or more. Key archaeological sites are featured in every chapter, all of which link in an evidentiary trail a great religious movement that
swept Mesoamerica, the Southwest, and the Mississippi valley, sometimes because of worsening living conditions and sometimes by improved agricultural yields thanks to global warming a thousand years ago.
