In the “triangular trade” system of the 1500s to the 1800s, europeans sent to africa.

Here were many things traded along the Triangular Trade Route. First of all, Europeans gave America things like onions, olives, turnips, coffee beans, peaches, pears, grains (wheat, rice, barley, oats), livestock (cattle, sheep, pigs, horses), and (most importantly) disease. Smallpox, measles, and other such sicknesses affected native Americans more because they were not immune to them like the Europeans were. In return for these things, colonies in the Americas gave Europeans pumpkins, turkeys, pheasants, potatoes, tomatoes, corn, vanilla, cacao, beans, pineapples, tobacco, and (most importantly) sugar and spices. Remember that before this, Europeans were eating plain bread (maybe the rich got a bit of butter) and barley or oatmeal with nothing on it. When they got sugar and spices, they went crazy for it. Europeans also gave textiles and wool to Africa in return for slaves that would be shipped to their colonies in the Americas
