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.
Effects of the Columbian Exchange: Plants, animals, culture, humans, diseases, etc. were transferred between the Americas, Europe, and Africa. Europe and Africa gained corn, tomatoes, and potatoes. This caused a massive population booms and an increase in wealth and capitalism and a decrease in feudalism in Europe. More Africans were born too, so the slave trade really took off.
