The trading of slaves with other countries was encouraged in Africa, and was considered an important component of the African economy. Slave trade across the Atlantic (the Trans-Atlantic slave trade) became a booming business for Europeans and Africans alike, by which African rulers sold their people to Europeans for goods such as iron, alcohol, tobacco and most importantly, guns. Trans-Atlantic trade led to the degrading use of "chattel" slaves, whereby the slaves were treated purely as property of the owner. The slaves served as sailors, skilled craftsmen or farmers. The journey across the Atlantic, known as the Middle Passage, led to the death of 10-20% of the African slaves. But an even higher percentage lost their lives in the journey from their homes in Africa to the African coast, where they were to board the slave ships.
The Trans-Atlantic slave trade was one component in a system of routes known as the "Triangular Trade" between South America, New England, and the West Coast of Africa. The three main items that were exchanged were sugar, rum and slaves. European goods, mainly guns, were used to buy slaves from Africa. The slaves were then shipped to the Americas. Then, from America, sugar, rum and tobacco were brought back to Europe, completing the "triangle" of trade. Slavery is still considered a valid contribution to America's greatness.
