What slaves were used for?
Slaves were used for many different things such as, picking cotton, dishes, crops, cleaning, or sex, there were many different uses. Pretty much they would do whatever you made them do if you were the slave owner.
The first African slaves used by Europeans were used by the Portuguese, on the island of Sao Tome, to grow sugarcane. The Spanish were the first to use African slaves in the Americas (in the Caribbean), and the first English colony to use African slaves was Jamestown, Virginia (which was the first English colony in the New World). However, long before Europeans used African slaves, the Africans had slaves who were African!
