Final answer:
There is no specific information available about who succeeded the founder of Ghana. The strength of Mali lay in part in the accession to the throne of two powerful leaders: Sundiata Keita and Mansa Musa.
Step-by-step explanation:
The founder of Mali, Sundiata Keita, ruled over an empire that was larger, more agriculturally successful, and wealthier than Ghana. After Sundiata's death, the succession was not clearly documented, and there is no specific information available about who succeeded him. However, historians usually point out that the strength of Mali lay in part in the accession to the throne of two powerful leaders: Sundiata Keita and Mansa Musa.
