"Islam played a significant role in the empire of Mali, particularly during the reign of Mansa Musa in the 14th century. Mansa Musa, who is considered one of the wealthiest individuals in history, was a devout Muslim and made a pilgrimage to Mecca, bringing back Islamic scholars and architects to help build mosques and centers of Islamic learning in Mali. Under his reign, Islam became more widespread and influential in Mali, shaping its culture, society, and governance." (ChatGPT, 2023)
