Princess Margaret was one of the most disliked party guests of her time.

When she was still alive, Queen Elizabeth II’s younger sister was known for her strong personality, petulance, and arrogance. Some of her frenemies also described her as bad-mannered.

As a teenager, Princess Margaret was known for being a high-spirited rebel princess. Royal historian A.L. Rowse revealed that after studying her at a garden party in 1956, he noticed that Princess Margaret was bored and ready to burst anytime.

And at a young age, Princess Margaret also discovered her best party trick very early on. In 1959, she abused the long-standing royal tradition of not starting parties until she has arrived.

Writer and aristocrat Nancy Mitford said that the dinner in honor of Princess Margaret in 1959 was scheduled for 8:30 p.m. but her hairdresser only arrived at the said time. After arriving at the venue, everyone noticed how Princess Margaret looked like a ball of fur two well-developed legs.

The day after, Princess Margaret rudeness and bad behavior extended to when she canceled a planned excursion due to cold but she actually just spent her entire day fitting clothes at the House of Dior.

Meanwhile, Princess Margaret also insisted on being called “ma’am.” It was very typical for her to lure in other people only to surprise them with her bad behavior later on.

Actor Derek Jacobi recalled his encounter with the royal while they were at a party.

“We got on terribly well, very chummy, talking about her mom and her sister, and she really made me feel like I was a friend. Until she got a cigarette out and I picked up a lighter and she snatched it out of my hand… ‘You don’t light my cigarette, dear… Oh no, you’re not that close,’” she told Jacobi.

Princess Margaret passed away on Feb. 9, 2002, at King Edward VII’s Hospital in London after suffering from a stroke.
