You seem to be referring to the Atlantic triangular slave trade. In this, the Americas sent Europe cotton, sugar, and tobacco. Europe sent Africa manufactured goods, textiles, and rum. Then, Africa sent slaves to the Americas, and the triangular trade continued. You might want to flip through your textbook a little on this one: the exact name varies from the one I gave you.
Answer: the Atlantic triangular slave trade (check in your text, the name varies)
