Step-by-step explanation:
The empire in Africa's second civilization that was more noted for its center of learning was the Mali Empire. Timbuktu, the capital city of Mali, became a leading Islamic center for education, commerce, and the slave trade. It attracted scholars, jurists, and Arab scholars from all over the Islamic world and established mosques and schools that became repositories of Islamic scholarship and learning. Over one hundred schools and eighteen universities were established in Timbuktu for Islamic studies.
