When people think of the richest people in history, more often than not they think of industrialists from the modern era, such as the Rothschilds, the Rockefellers, or the Carnegies. Perhaps some would also name current billionaires such as Bill Gates, Jeff Bezos, or the many wealthy Arab sheiks. However, the richest person in all of history is a Malian ruler named Musa Keita I, tenth Mansa of the Empire of Mali (Mansa is a title like ‘sultan’ or ‘emperor’). He was so rich and extravagant in his spending that he disrupted Egypt’s economy just by passing through!
