Musa I of Mali was the tenth Mansa, which translates to “King of Kings” or "Emperor". Musa was a devout muslim and a very generous man. During his pilgramage to Mecca in 1324, he was able to single handedly devalue gold in the Middle East.
Each city that Musa visited was generously given large quantities of gold, and he made it a goal to build a mosque each and every Friday. He was also generous to the poor, giving them gold and even trading gold for souveniers. After the huge influx of gold to these regions, the gold became devalued, causing prices of goods to inflate rapidly.
To bring order to the gold market, Musa borrowed all the gold he and his entourage could cary from banks in Cairo. Even that was not enough to stop the price of precious metals from being devalued in the region for the next decade.
