Final answer:
Ibn Battuta visited Mali after 1337, during the reign of Mansa Sulayman, the brother of Mansa Musa. Sulayman's rule was characterized by its strong justice system, ensuring security throughout the empire, which was largely inhabited by devout Muslims.
Step-by-step explanation:
The renowned Muslim geographer Ibn Battuta traveled to Mali during the reign of Mansa Sulayman, who succeeded his brother Mansa Musa. Ibn Battuta's journey occurred in a period after the death of Mansa Musa, sometime around the middle of the 14th century. According to historical records, Mansa Musa's reign lasted from 1312 to 1337, and his brother's reign followed, so Ibn Battuta's visit would have occurred after 1337. However, the exact years of Mansa Sulayman's rule are less certain.
Mansa Sulayman's reign was noted for its strict adherence to ensuring security and justice, as attested by Ibn Battuta's account of Mali having "complete security in the land". As an authority, Mansa Sulayman was known to be tough on crime and any form of violence, which helped foster a sense of safety among the populace. During this time, the Empire of Mali thrived as a center of Islamic learning and piety, along with being an influential hub of trans-Saharan trade. The inhabitants, devout Muslims, maintained a society that Ibn Battuta described as secure and faithful.
