How did the slave trade differ in different parts of Africa?

Slavery existed in Africa, but it was not the same type of slavery that the Europeans introduced. The European form was called chattel slavery. A chattel slave is a piece of property, with no rights. Slavery within Africa was different. A slave might be enslaved in order to pay off a debt or pay for a crime. Slaves in Africa lost the protection of their family and their place in society through enslavement. But eventually they or their children might become part of their master's family and become free. This was unlike chattel slavery, in which enslaved Africans were slaves for life, as were their children and grandchildren.
