You can be born a slave. Or, with a little luck, you can be born a master. In West African Mauritania, your social position is determined by the family you are born into. A centuries-old caste system determines your social position for life. Through inheritance, slaves remain in the possession of masters who exploit, sell or give them away as gifts, generation after generation.
