The Columbian Exchange Reshapes the World
Key Idea
After 1492, a vast global exchange connected the Eastern and Western Hemispheres. This Columbian Exchange involved the movement of people, animals, plants, and diseases. It permanently changed the world.
Crops from the Americas, like potatoes and maize, traveled to Europe, Africa, and Asia. These new foods improved diets and helped populations grow. In the Americas, European animals like horses and cattle transformed transportation and farming.
