Beyond 1492: The Columbian Exchange
Dr. Benjamin Ehlers, UGA Department of History
Tuesday, July 17, 1:30 pm Gardenside Room
The State Botanical Garden of Georgia

The historian Alfred Crosby used the term Neo-Europes to describe the regions of the world flooded by European emigrants after 1492. North America, Australia, Argentina: these areas shared Europe's climate, but lacked the natural competitors to check the expansion of Old World flora and fauna. "Euro-Weeds,“ a word Crosby applied to animals and microbes as well as noxious plants, thrived in their new environment, as witnessed by the spread of peaches, oranges, and rye, as well as feral pigs and horses. Beyond the navigational skill of Columbus and the military acumen of Cortes, the European colonization of new worlds depended upon the propagation of crops, livestock, and diseases such as smallpox.

This presentation will begin with a discussion of Crosby's model, with reference to the voyages of Columbus and the Spanish conquest of Mexico. We will then proceed to the Heritage Garden to reflect upon the lasting results of the Columbian exchange in the American Southeast.
