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.
The Triangular Trade was a trading triangle that went between England, West Africa, and the New England Colonies. The English first went to West Africa to trade English goods for African Slaves. Then they went to the New England colonies to trade the slaves for cash crops. This is the triangular trade.
