Musa Keita I (c. 1280—c. 1337) was the tenth
Mansa, which translates as "sultan" (king), "conqueror",
 or emperor
 of the wealthy West African
Mali Empire. At the time of Musa's rise to the throne, the Malian Empire consisted of territory formerly belonging to the
Ghana Empire in present-day southern
Mauritania and in Melle (
Mali) and the immediate surrounding areas. Musa held many titles, including Emir of Melle, Lord of the Mines of Wangara, Conqueror of Ghanata, and at least a dozen others.
 It is said that Mansa Musa had conquered 24 cities, each with surrounding districts containing villages and estates, during his reign.
 During his reign Mali may have been the largest producer of gold in the world at a point of exceptional demand. One of the richest people in history, he is known to have been enormously wealthy; reported as being inconceivably rich by contemporaries, "There's really no way to put an accurate number on his wealth" (Davidson 2015).
