Akbar I
The Mughal Empire once ruled almost all of modern day India, and under the control of their third ruler, Akbar I or Akbar the Great, they became one of the most powerful empires in the world.
Akbar’s court was extravagant and luxurious—but it’s hard to truly grasp just how much wealth he controlled.
There’s No Comparison
While there is no real way to accurately compared Akbar I’s wealth to the modern day, his empire controlled an unbelievable 25% of the world’s GDP.
Since he had complete control over the empire, that’s like having a net worth of over $20 trillion in today’s dollars.
Andrew Carnegie
In the late 1800s, steel was the hottest commodity on Earth—and if you needed steel in America, you got it from Andrew Carnegie. He built his first steel mill in 1875. By 1901, he sold the Carnegie Steel Company that he’d built in the decades since for over $300 million.
He Gave It All Away
Adjusted for inflation, Andrew Carnegie’s net worth reached $310 billion. After selling Carnegie steel, he became a famous philanthropist, eventually giving away $350 million in his lifetime—nearly 90% of his total wealth.
Henry Ford
Henry Ford—and the affordable Model Ts that rolled off of his ingenious assembly lines—completely revolutionized the modern world as we know it.
This made Henry Ford extremely famous—and extremely rich.
You Can’t Take It With You
By the time of his death, Henry Ford was worth an estimated $180 billion (in today's dollars), leaving most of his wealth to the Ford Foundation, which is still running today.
As recently as 2019, the Ford Foundation provided nearly $200 million in grants and initiatives.
John of Gaunt
John of Gaunt was the lowly fourth son of King Edward III. That meant he’d never rule a kingdom himself—but he made it work. Between his royal birth, lucky land grants, and some extremely rich wives, he became one of the richest and most powerful men in the world.
There’s Always Money In Castles
In feudal England, all the money was in land—and John of Gaunt had a lot of land. With dozens of castles across England and France, modern estimates put Gaunt’s wealth around the equivalent of $110 billion.
Jay Gould
Jay Gould was maybe the least popular of 19th-century America’s Robber Barons. He made his money in railroads and on the stock market—but his business practises weren’t exactly on the level.
He Crashed The Stock Market
Jay Gould’s tactics peaked his net worth at around the equivalent of $70 billion in today’s dollars—and made him absolutely despised. His shady attempt to corner the gold market caused a mass panic and led to the infamous Black Friday of 1869.
Mansa Musa I
Jay Gould tried to corner the gold market, but he had nothing on Mansa Musa I. Leader of the Mali Empire in the 14th century, Musa controlled trade across the Sahara—most importantly gold mined south of the desert—and it made him perhaps the single richest person in history.
He Was The Original John D. Rockefeller
Mansa Musa I was famous for his wealth and generosity even in his time. Some scholars claim that he gave away so much gold when he travelled through Egypt that he caused a national depreciation in its value.
While his wealth and power are almost impossible to truly compare to modern society, some sources have estimated his personal net worth at more than $400 billion.
Mir Osman Ali Khan Was The Richest Man On The Planet
The ruler of the princely state of Hyderabad during the British Raj, Time magazine called Mir Osman Ali Khan “richest man on the planet” in 1937. He owned 50 Rolls-Royces and used a 185-carat diamond the size of a lime as a paperweight.
Diamonds Are A Billionaire’s Best Friend
Most billionaires made their money in boring stuff like steel and railroads. Mir Osman Ali Khan’s came from his state’s rich diamond mines—hence the paper weight. Adjusted for inflation, Khan’s net worth was upwards of $230 billion.
John D. Rockefeller Was An Oil Man
The son of a con artist, John D. Rockefeller’s shrewd instincts led to the creation of Standard Oil, which, before it was broken up in a landmark antitrust suit, refined up to 90% of all American oil.
He Was The First Ever Billionaire
Maybe John D. Rockefeller’s biggest claim to fame is that he was the world’s first confirmed, actual billionaire. Not adjustment for inflation, just one billion dollars in his bank account. But that doesn’t do it justice. Today, his net worth would be more like $340 billion.
Alan Rufus
Alan Rufus is proof that it’s not about how great you are—it’s about who you know. At first, Rufus was just a relatively minor landowner in Normandy. Then he crossed the English Channel with William the Conqueror in 1066. That changed things a little bit.
He Was In The Right Place At The Right Time
Rufus must have impressed the Conqueror, because after the Battle of Hastings, William rewarded him with control of the Honour of Richmond, one of the most important and productive regions in England.
By the time he passed, Rufus’s fortune was £11,000. That may seem small—but compared to net income, that’s the equivalent of $180 billion today.
The Commodore Built Railroads
As railroads began stitching North America together, Cornelius Vanderbilt was leading the charge—and getting filthy rich while doing it. Nicknamed “The Commodore,” Vanderbilt’s gruff behavior made him a controversial figure in his own time.
He Built A Legacy
The Commodore amassed the equivalent of $185 billion in his lifetime, providing the foundation for the Vanderbilts to become one of the richest and most powerful families in America—including modern celebrities like Anderson Cooper and Timothy Olyphant.
He Came, He Saw, He Got Rich
William of Normandy was a bastard by birth, but that didn’t stop him from grasping control of his duchy with an iron fist. Though he had only a tenuous claim to the throne of England, he invaded in 1066, defeated the weak English king, and changed world history forever.
Oh, and he got stinking rich in the process.
To The Winner Go The Spoils
Conquering England made William of Normandy unimaginably rich. Modern estimates put his net worth at over $220 billion. And he enjoyed the fruits of his labor, too. By the time of his funeral, his body was so bloated that they couldn’t fit him in his coffin.
William de Warenne Proved Himself
Back in Normandy, William de Warenne was just the second son of a minor landholder—he didn’t stand to make much of a dent in the world. But after proving himself on the battlefield, de Warenne got himself noticed by William the Conqueror himself.
If you want to be one of the richest people in history, that’s a very good start.
He Got The Land
De Warenne impressed again at the Battle of Hastings, and got some seriously juicy lands in England as a reward. The value of of his estates by the time he died is estimated at $150 billion in today’s dollars.
