The Columbian Exchange is a term used to denote the world-changing exchange of agricultural goods, slave labor, diseases, and ideas between the Eastern and Western Hemispheres that occurred after the year 1492 CE.
Okay Americas, you give me all your money, food, and resources, and I'll give you a religion you don't want and an incurable illness. Oh, and I'll even throw in some new crops you can grow for me.. There you pretty much have the essence of the Columbian Exchange. A phrase coined by historian Alfred Crosby, the Columbian Exchange describes the interchange of plants, animals, and diseases between the Old World and the Americas following Columbus' arrival in the Caribbean in 1492.
