What is the meaning of the term "triangle trade?"
Technically, a triangle (or triangular) trade can occur any time that three regions are involved in trade in a situation where each region has things that are wanted by only one other region. In historical terms, this term is generally used to refer to the triangular trade across the Atlantic between the Caribbean, Europe (or New England) and Africa.
In the Atlantic triangular trade, Europe (or New England) sent manufactured goods to Africa. There, they were exchanged for slaves that had been taken by the coastal African kingdoms. These slaves were then brought across the Atlantic to be sold in the Caribbean. This was the second leg of the triangle. The third leg took things like sugar, rum, and molasses from the Caribbean back to Europe.
