Keita dynasty in the context of "Mali Empire"

Mansa Musa (reigned c. 1312 – c. 1337) was the ninth Mansa of the Mali Empire, which reached its territorial peak during his reign. Musa's reign is often regarded as the zenith of Mali's power and prestige, although he features less in Mandinka oral traditions than his predecessors.

Musa was exceptionally wealthy, to an extent that contemporaries described him as inconceivably rich; Time magazine reported: "There's really no way to put an accurate number on his wealth." It is known from local manuscripts and travellers' accounts that Mansa Musa's wealth came principally from the Mali Empire's control and taxing of the trade in salt from northern regions and especially from gold panned and mined in Bambuk and Bure to the south. Over a very long period Mali had amassed a large reserve of gold. Mali is also believed to have been involved in the trade in many goods such as ivory, slaves, spices, silks, and ceramics. However, presently little is known about the extent or mechanics of these trades. At the time of Musa's ascension to the throne, Mali consisted largely of the territory of the former Ghana Empire, which had become a vassal of Mali. The Mali Empire comprised land that is now part of Guinea, Senegal, Mauritania, the Gambia, and the modern state of Mali.
