Final answer:
Historical records do not pinpoint exact moments when subjects could not be in Mansa Musa's presence, but his and Mansa Sulayman's authoritative rule imply restricted access during important ceremonies.
Step-by-step explanation:
The presence of anyone was not allowed when the Mansa, or emperor, of the Mali Empire engaged in particular activities. From the historical accounts, it is not explicitly mentioned which specific activities barred others from the presence of the Mansa, but we do know of significant events during the reigns of Mansas like Musa I and his brother, Sulayman, that indicate the reverence and authority they commanded.
For instance, Mansa Musa, who ruled from 1312 to 1337, is renowned for his pilgrimage to Mecca, which showcased the immense wealth and devout Islamic faith of the Malian empire. No detail, however, stipulates a specific moment when subjects were forbidden from being in his presence. Similarly, Mansa Musa’s brother, Mansa Sulayman, noted for his despotism, exercised strict control and ensured 'complete security' in the land, showing no mercy for violence. Such descriptions of the ruler's powers imply that, generally, access to the Mansas would have been highly restricted during significant state or religious ceremonies.
The Mali Empire, under rulers like Mansa Musa and Mansa Sulayman, reached the peak of its prosperity and influence, thriving on the trade of gold and salt, as well as on its significant contributions to Islamic scholarship, particularly in the infamous city of Timbuktu.
