The richest royals in the world

Many royals are known for their power, prestige, notoriety, and money. There are those who are part of centuries-old dynasties, others relatively new to the scene, and several who came to their riches through their royal titles. Some royals earned their fortunes differently, whether through their philanthropic efforts or as the subject of tabloid gossip due to affairs and questionable business practices.

Of late, one royal has gained notoriety for eschewing his official role in favor of expatriate life in another country. (Yes, he is on this list.) Then, there are the royals working toward building a better future for their country—and the planet.

Stacker looked at the world's richest royals and ranked the top 25 by net worth, according to Celebrity Net Worth. What does that wealth look like? It runs from a "low" of $60 million to a high of $30 billion.

How do these royals live with their wealth? One king has 30 poodles, one of which was named Air Chief Marshal in the Royal Thai Air Force. There's an Italian prince with a food truck in Los Angeles and a British Lord who capitalized on their famous title with a gourmet sandwich fast-food chain. Two royals on the list have competed in the Olympics. Another king has had 15 wives and 36 children.

So who are these fascinating, wealthy royals? Read on to find out.

Prince Henry Charles Albert David is the Duke of Sussex, second son of King Charles III and Diana, Princess of Wales, and fifth in line to the British throne.

In January 2020, after reports of severe conflict within the royal family following Prince Harry's marriage to actress Meghan Markle, the Duke surrendered his position as a senior member of the royal family and moved with his family to California. That October, the couple founded the nonprofit Archewell Inc.

Prince Harry's wealth is largely tied to land holdings he still retains in Britain, but he's also made quite a financial and literary splash with the publication of "Spare," a memoir released by Penguin Random House in 2023. The book sold 3.2 million copies worldwide in its first week of publication alone.

#21. Princess Caroline of Monaco

The older sister of Princess Stéphanie, Caroline has two royal titles: Her Serene Highness, Princess Caroline of Monaco, and Her Royal Highness, the Princess of Hanover. The latter title is due to her current marriage to Prince Ernst August of Hanover.

Caroline was the president of the Monegasque Committee for the International Year of Children. She also founded Jeune J'écoute, a hotline for troubled youth. Such endeavors led the princess to be named a UNESCO Goodwill Ambassador.

H.S.H. Caroline has been married three times. She divorced her first husband, Philippe Junot, and was granted an annulment by the Catholic Church. Her second husband, powerboat racer Stefano Casiraghi, perished in a 1990 racing accident. The couple had three children together: Andrea, Charlotte, and Pierre.

#18. John Montagu

- Net worth: $100 million

What is a royal to do when their famous name evokes hunger? They capitalize on it. Such is the case for John Montagu, the 11th Earl of Sandwich, a direct descendant of John Montagu, the 4th Earl of Sandwich.

As for the 4th Earl of Sandwich, the word is he was fond of gambling and asked for roast beef between two slices of bread so he could continue playing cards with no disruption. Whether or not that story is true, Montagu embraced the legend as a restaurateur. He launched Earl of Sandwich, a chain of 30 U.S.-based restaurants, with his son, Orlando, and Planet Hollywood founder Robert Earl.

Montagu doesn't spend his days taking sandwich orders, though. He serves in the House of Lords and provides public access to the family's heritage property.

- Net worth: $100 million

The grandson of King Umberto II, the last king of Italy, and Queen Maria Jose, Emanuele Filiberto of Savoy is the Prince of Piedmont and Venice. Another title he vied for: the king of the dancefloor, when he competed in Italy's version of "Dancing with the Stars" in 2009. The dance competition was not Filiberto's first foray into the entertainment industry. After myriad appearances in the media over the years, he created two production companies, Savoy & Gregory and Royal Me Up.

In 2003, Filiberto married French actor Clotilde Courau. The prince has since created a line of T-shirts and owns a pasta food truck in Los Angeles. In late 2022, he made headlines for attempting to buy the Savoia football club to "keep it away" from the mafia.

He recently began efforts to reclaim jewels belonging to the House of Savoy. Worth an estimated $335 million, the gems have been in possession of the Italian government and the Bank of Italy since the abolition of the monarchy months after World War II. Thus far, Filberto's efforts to retrieve the jewels have failed.

Born in 1952, Maha Vajiralongkorn is the son of Queen Sirikit and King Bhumibol Adulyadej. Twenty years later, Vajiralongkorn's father pronounced him crown prince. Bhumibol passed away in 2016, but it wasn't until 2019 that Vajiralongkorn would officially step into the role of Thailand's king.

In 1977, Vajiralongkorn married his cousin, Princess Soamsawali, who gave birth to their daughter, Princess Bajrakitiyabha, the following year. During the marriage, he began an affair with Yuvadhida, an actress. They produced five children between 1979 to 1987, eventually marrying in 1994. By 1996, Vajiralongkorn denounced Yuvadhida and disowned their four sons. The prince's third marriage was to Srirasmi, a lady-in-waiting who gave birth to their son Prince Dipangkorn in 2005.

Days before his 2019 coronation, Vajiralongkorn married former Thai Airways flight attendant, Suthida, declaring her Queen Suthida Vajiralongkorn Na Ayudhya. Two months after his marriage to Queen Suthida, King Vajiralongkorn announced he was taking an official consort, Maj. Gen. Sineenat Wongvajirapakdi. Though that's not who he named Air Force chief marshal in the Royal Air Force—that would be Foo Foo, one of his 30 poodles.

Thailand's Crown Property Bureau, valued at over $40 billion, comes under Vajiralongkorn's rule.
