Meet Mansa Musa, The 14th Century African King & Richest Man In History (Worth Over $4Trillion)
Economists have determined that the West African emperor’s vast wealth most likely positions him as the richest person in history. But just how much money did he have? And what did he do with it?
Emperor Mansa Musa I came to reign over the Malian Empire through somewhat strange means.
Before embarking on a long and somewhat arduous pilgrimage to Mecca (called a Hajj in the Muslim religion), then-emperor Abubakari II deputized Musa to temporarily assume his role. An “on-call” emperor was a common feature throughout the history of the empire. It’s somewhat comparable to the modern-day role of a vice president.
This arrangement worked out fine until Abubakari set out to explore the far side of the Atlantic Ocean and never returned. Musa, then, inherited the throne since he had been deputized. But Musa wasn’t a nobody: His great-uncle was Sundiata Keita, who founded the Malian Empire.
As many a late night infomercial will tell you, there are lots of ways to attain wealth. Musa got his primarily through trading gold and salt, which were found in abundance in West Africa at the time. He also used the money to strengthen the country’s cultural centers, particularly Timbuktu, which he annexed in 1324.
It was when Musa made his Hajj to Mecca — an important part of the Muslim religion, which was very widespread in the region at this point in history — that the rest of the world became aware of the extent of his wealth.
Because he had so much to spend, his caravan throughout Cairo, Medina, and finally to Mecca had a procession of more than 60,000, dozens of animals, and plenty of gold. In fact, as they traveled, Musa and his entourage gave gold away to people in the streets.
They also bought lots of stuff — so much stuff, in fact, that they actually messed up the global economy for a while: The gold he spent circulated, and there was so much of it, that the value actually went down.
The disruption eventually evened out, in part because Mansa Musa began borrowing from lenders in Cairo (despite the high interest rate) and essentially single-handedly controlled the price of gold in the Mediterranean.
He actually ended up using most of it to build a great number of mosques (legend says he built one every Friday of his reign), the most famous of which is the Djinguereber Mosque. He also commissioned many universities throughout the kingdom — many of which, along with the mosques, are still standing today, some 700 years later.
Musa quite literally put himself, and his empire, on the map when he made this journey — maps from Italian cartographers during his reign had artists add his likeness, holding a nugget of gold of course. He extended the reach of his trade ports and became one of the most powerful rulers of his time — if not in all of history.
Musa ruled for about 25 years according to historian’s best estimates: they believe he died in 1332, at which time his son inherited the throne.
In the spirit of other extremely wealthy people who ultimately become philanthropists, you might wonder how he stacks up against some contemporary billionaires, like Bill Gates, John D. Rockefeller, or Warren Buffett.
When adjusted for inflation, Mansa Musa’s wealth is believed to have been around $4 Trillion. The only person who comes close to Musa’s wealth is John D. Rockefeller, whom economists believe amassed a worth of around $400 billion.
Of course, Rockefeller wasn’t just in the oil business, he virtually was the oil business. As for Bill Gates, he comes in at several hundred billion below Musa at $100 billion. That’s still a lot of money, but will anything Gates made still be around in 900 years?
In the end, historians and economists find Mansa Musa’s legacy rich not because of how much money he had, but how he used it.
