So, you think you’re rich? Let me introduce you to Aristotle Onassis, the man who made Croesus look like he was clipping coupons. This Greek shipping magnate wasn’t just wealthy—he was the richest man in the world in the 1960s and 70s. And he did it all while wearing sunglasses indoors and marrying Jackie Kennedy. Seriously, the guy had swagger.

The Super-Tanker King Who Started with Nothing

Onassis was born in 1906 in Turkey, but his family fled to Greece. He started his empire by buying six ships during the Great Depression. Why? Because everyone else was panicking, and Onassis saw a fire sale on the high seas.

By the 1950s, he owned the world’s largest private fleet of supertankers. He’d laugh at oil companies and say, “You need me more than I need you.” And he was right—his ships were like floating treasure chests.

The Most Expensive Wedding Cake in History

Onassis famously married Jacqueline Kennedy in 1968, six years after JFK died. The wedding gift? A $20 million diamond ring. That’s like buying a small island and wearing it on your finger.

The gossip columns went nuts. Headlines screamed, “Jackie O Marries the Minotaur!” But Onassis didn’t care—he just lit another cigar and checked his bank balance. The whole affair was so dramatic, it probably funded a dozen soap operas.

The Titanic-Sized Ego

Did he have a yacht? Oh, honey. He owned the Christina O, a 325-foot floating palace. It had a swimming pool that could be drained and turned into a dance floor. Barstools were covered in whale foreskin (yes, really), and the deck had a backgammon board made of tiles.

He once told a reporter, “If women didn’t exist, all the money in the world would have no meaning.” Smooth, Ari. Smooth. But also, gross—he was famously a serial womanizer.

The Greatest Flex: Buying a Whole Island

In 1962, Onassis bought Skorpios, a private island in Greece. He had it completely remodeled, built a private chapel, and planted thousands of palm trees. He then hosted parties with Winston Churchill, Maria Callas, and Greta Garbo. No, I’m not making this up—Churchill fell asleep at one dinner and Onassis just shrugged.

He even built a personal heliport in the 1960s. That’s like having a private Uber for your helicopter. “Just land it on the lawn, mate.”

The Drama: Maria Callas vs. Jackie O

For years, Onassis was the lover of opera diva Maria Callas. Then he dumped her for Jackie. Callas was so furious she didn’t sing for seven years. Imagine being so powerful you can silence the world’s greatest soprano with a breakup text (well, a telegraph).

The real kicker? Onassis’s rival, shipping tycoon Stavros Niarchos, married Jackie’s sister. Yes, the family had a yacht-based arms race. Their Christmas dinners must have been a nightmare. “Pass the caviar, you stole my mistress!”

The Very Un-Funny Ending

Onassis’s life took a dark turn in the 1970s. His son, Alexander, died in a plane crash. His daughter, Christina, battled addiction. And his marriage to Jackie was icy—she once said living with him was “like living in a mafia movie.”

By 1975, Onassis was dead from respiratory failure. His last words? "I have everything, but I have nothing." Oof. That’s a punchline you don’t want.

Fun Facts to Stun Your Friends

He once gave a $25,000 tip to a waiter for bringing the right brand of champagne. The waiter promptly fainted.

He owned 7,000 pairs of shoes, but never wore sneakers. “I don’t walk. I am driven.”

The Greek government tried to tax him, so he bought a controlling share of their national airline. Stunt king.

Was He Happy? (Probably Not)

Onassis had three yachts, a private island, and a wife who was the most famous woman on Earth. But he was lonely, ugly to his rivals, and died with a broken heart. The lesson? Money can buy a superyacht, but it can’t buy you dinner with your dead son. Too dark? Sorry—rich people problems.

Still, the man changed business forever. He pioneered the use of tax havens and flag-of-convenience ships. He basically invented the modern billionaire playbook. And he did it all while wearing a toupee in the wind.

So pour a glass of ouzo for Onassis. He was a scoundrel, a genius, and the king of the high seas. And he probably would have hated this article—unless he owned the newspaper it was printed in. Which, knowing him, he probably did.
