Musa, Mansa (1280-1337) Mansa Musa, fourteenth century emperor of the Mali Empire, is the medieval African ruler most known to the world outside Africa. His elaborate pilgrimage to the Muslim holy city of Mecca in 1324 introduced him to rulers in the Middle East and in Europe.
Musa is known to have visited the Mamluk sultan of Egypt, Al-Nasir Muhammad, in July of 1324. But Musa's generous actions inadvertently devastated the economy of the regions through which he passed.
