King Charles' Cousin, Who Renounced His Royal Status to Marry a Commoner, Died in Athens — Report

King Charles III's first cousin once removed and the last living grandson of King George I of Greece has died at the age of 85, marking the end of an important chapter in European royal history.

Historian and author Michel de Grece passed away in a hospital in Athens, according to the Greek newspaper Ekathimerini on July 28. Known as Prince Michael, he was reportedly the last living grandson of King George I of Greece and had close ties to the British royal family.

The 85-year-old Greek prince was a first cousin of the late Prince Philip, Duke of Edinburgh, who was married to Queen Elizabeth II. This connection made Michel a first cousin once removed to King Charles III.

Alongside his royal lineage, Michel was known for his unique personal life. In 1965, he made headlines by giving up his royal rights to marry Marina Karella, an artist and commoner.

This significant break from royal tradition marked a turning point in Michel's life. The couple had two daughters, Princess Alexandra and Princess Olga, and five grandchildren.

Unlike many of his royal relatives, Michel chose to stay in Greece. He remained in the country even after the failed 1967 counter-coup, during which then-King Constantine attempted to overthrow the ruling military Junta. This decision reflected his strong connection to his homeland and his dedication to Greece.

Michel's life in Greece greatly influenced his work. The historian wrote extensively on Greek history, the Ottoman Empire, and European royalty. His passion for history was evident in his many books, which continue to be influential.

Beyond sharing his historical work, Michel shared stories about his family, life, and travels on his Instagram page, giving followers a glimpse into his personal experiences. He also shared his views on the British monarchy in 2021.

In one instance, Michel spoke about Charles, expressing empathy for the challenges he faced. He said, "I don't know if he's perfect or not...What I know is that he can hardly do better than what he does now...I think he does his best. [Queen Camilla], too. It's very difficult."

Michel had no regrets about following his own path away from the royal limelight and did not feel envious of Charles's position. "I do not envy him at all, really – poor guy. And he does it with dedication, with a sense of humor. She, too. But I would not like that job at all," he shared.

In addition to his views on the British monarchy, Michel also reflected on the state of many families today, noting that he observed a lot of "fighting each other, hating each other" within them.

He expressed his deep affection for his own family. "I created my own family, whom I adore—my wife, children, and grandchildren. That is the most important thing for me. My life has been one of experiences, of discoveries. And I’m still very curious. Now, I'm discovering technology through my grandchildren. It's fabulous. My life has been an adventure. It still is," he explained.

Details of Michel's funeral arrangements are yet to be announced. His passing signifies the end of a notable chapter in European royalty.

Michel's unique personal choices and influential writings have created a lasting legacy, ensuring his impact on Greek and European history will be remembered for years to come.
