Money makes the world go round, but who actually owned the world? If you look at the Bloomberg Billionaires Index today, you'll see names like Elon Musk, Jeff Bezos, or Bernard Arnault swapping the top spot like a game of musical chairs. But honestly, compared to the heavyweights of the past, today's centibillionaires are kinda playing in the minor leagues.
The history of world richest person isn't just a list of bank balances. It's a story of salt, silk, oil, and sometimes, just owning the entire country.
The King of Gold: Mansa Musa
You've probably heard the name, but the scale of this guy's wealth is hard to even wrap your head around. Mansa Musa ruled the Mali Empire in the 14th century. Back then, Mali was basically the world's primary source of gold.
When Musa went on his pilgrimage to Mecca in 1324, he didn't just pack a suitcase. He brought a caravan of 60,000 people. We're talking thousands of soldiers, heralds in silk, and dozens of camels each carrying hundreds of pounds of pure gold.
He was so generous—or maybe just showing off—that he handed out so much gold in Cairo that he actually crashed the local economy. The value of gold plummeted for over a decade because he’d flooded the market. Imagine being so rich that your vacation spending causes a ten-year national recession. Historians usually give up on putting a modern dollar amount on him, calling his wealth "incomprehensible," though some peg it at a theoretical $400 billion.
The Banker Who Owned Emperors
Fast forward to the 16th century. Meet Jakob Fugger. Most people have never heard of him, but he was basically the venture capitalist of the Renaissance.

Fugger wasn't a king. He was a merchant from Augsburg. But he had something better than a crown: he had the "Fugger News Letters," which was basically the world's first private intelligence service. He knew which ships were sinking and which kings were broke before anyone else.
At one point, he bankrolled the Holy Roman Emperor, Maximilian I, and even paid for the army that secured the election of Charles V. He basically owned the debt of Europe’s most powerful people. When he died in 1525, his fortune accounted for about 2% of Europe's entire GDP. If you scaled that to the modern U.S. economy, he’d be worth over $500 billion.
The Monopoly Era: Rockefeller and Carnegie
When we talk about the history of world richest person in the industrial age, it’s a two-man show. John D. Rockefeller and Andrew Carnegie.
Rockefeller was a bookkeeper who became obsessed with efficiency. He didn't just want to find oil; he wanted to control the pipes, the wagons, and the refineries. By the time Standard Oil was at its peak, he controlled 90% of the oil in America.

- Rockefeller’s Peak: In 1916, he became the first person to reach a $1 billion net worth.
- The GDP Metric: At his death, his wealth was about 1.5% to 2% of the U.S. GDP.
Then there’s Andrew Carnegie. The Scottish immigrant who started as a "bobbin boy" in a factory for $1.20 a week. He built the steel mills that created the American skyline. In 1901, he sold Carnegie Steel to J.P. Morgan for $480 million.
The story goes that Morgan told Carnegie, "Congratulations, Mr. Carnegie, you are now the richest man in the world." Carnegie spent the rest of his life trying to give it all away, famously saying that the man who dies rich dies disgraced.
The Modern Shift: From Assets to Equity
For most of the 20th century, the "richest" title was a bit murky. It was often held by people like the Nizam of Hyderabad, who supposedly used a 185-carat diamond as a paperweight, or the Sultan of Brunei.
But then the 1980s hit.
The way we measure the world's wealthiest changed from "who owns the most land or gold" to "who owns the most stock." This is why you see the massive volatility now.
- Yoshiaki Tsutsumi: In the late 80s, this Japanese real estate mogul was the richest man on Earth during the Japanese asset bubble.
- Bill Gates: He held the top spot for 18 of the 24 years between 1995 and 2017.
- The Tech Explosion: Since 2018, it's been a tight race between Bezos, Musk, and Arnault.
Musk’s wealth is a weird beast. It’s not cash sitting in a vault like Mansa Musa’s gold. It’s tied to the market’s belief in Tesla and SpaceX. If the stock drops 10% in a morning, he "loses" more money than most people earn in a lifetime.
Why This Matters Today
Looking at the history of world richest person shows us a pattern. Wealth used to be about physical resources—land, salt, gold, and oil. Today, it’s about "intangibles"—software, brands, and future-tech.
The scale has also become more concentrated. While Mansa Musa’s wealth was arguably a larger share of the global pie, the sheer speed at which modern billionaires can gain (or lose) $100 billion is something history has never seen before.
If you want to track this yourself or understand the shifts in global wealth, keep an eye on these three indicators:
- Interest Rates: When money is "cheap" (low rates), tech billionaires see their net worth skyrocket because future earnings are worth more today.
- Energy Transitions: Just as Rockefeller rode the oil wave, the next "richest person in history" will likely be whoever dominates the post-carbon energy grid.
- The GDP Gap: Watch the percentage of wealth held by the top 0.01% compared to a country's total GDP. Historically, when this gap gets too wide, it usually leads to major regulatory shifts or "trust-busting," much like what happened to Rockefeller in 1911.
The title of "richest" is always temporary. Whether it's a 14th-century king or a 21st-century rocket scientist, the throne eventually changes hands.
