Triangular trade started in the mid-15th century. Trading took place between America, Europe and Africa. It was also referred to as the Trans-Atlantic trade, as the route used to conduct this trade was on the Atlantic Ocean.
During the fifteenth and sixteenth centuries, European traders started to get involved in the Slave Trade. European traders had previously been interested in African nations and kingdoms, such as Ghana and Mali, due to their sophisticated trading networks. Traders then wanted to trade in human beings. They took enslaved people from western Africa to Europe and the Americas. At first this was on quite a small scale but the Slave Trade grew during the seventeenth and eighteenth centuries, as European countries conquered many of the Caribbean islands and much of North and South America.
