What are the differences between the types of slavery traditionally practiced in africa and the slavery that developed in the new world?

In Africa, the slaves were usually a product of war or conflict. Blacks owned black.  They were given freedom to wonder the village. Being a slave in Africa did not mean you were a slave for life. They were usually defined as dependents, often assimilated into their own family. Europeans thought of them as chattel. This is why the slaves were slaves for life. They had no freedom and usually treated badly.

Iwould have to say c. the german americans.
