By the time Columbus had arrived, dozens of plants were in regular use, the most important of which were maize (corn), potatoes, cassava, and various beans and squashes. Lesser crops included sweet potato, papaya, pineapple, tomato, avocado, guava, peanuts, chili peppers, and cacao, the raw form of cocoa.
Traders returned to Europe with maize, potatoes, and tomatoes, which became very important crops in Europe by the 18th century. The term was first used in 1972 by American historian Alfred W. Crosby in his environmental history book The Columbian Exchange.
