Princess Margaret and Queen Elizabeth II were always compared to each other while they were growing up. Since Her Majesty is the monarch, her younger sister was viewed as the spare.

In fact, there were also rumors suggesting that Princess Margaret was jealous of the Queen. However, this was denied by royal biographer Christopher Warwick. While speaking with Express, Warwick discussed some of the late royal’s issues with her older sister.

“Margaret was, of course, the younger daughter and she obviously was the younger sister. She once said to me, ‘I’ve never suffered from second daughter-itis… I never minded being referred to as the younger daughter, but I do mind being referred to as the younger sister,’” he said.

Princess Margaret also had a stern reaction towards the education that she and the Queen attained. When the Queen was just a kid, it was already known that she will head the monarchy one day. And as such, they decided that it was a good idea for her to have lessons in constitutional history and other subjects.

The lessons were taught by Sir Henry Martin, who was the vice provost at Eton College. During Warwick’s conversation with Princess Margaret, he asked her how she felt about not having further education just like the Queen.

“And the princess said, ‘Yes, that was always a bone of contention…’ So it’s little things like that… She minded not having the higher education, but that doesn’t mean she was jealous of her sister for having had it,” Warwick explained.

Several years later, Her Majesty and Princess Margaret’s differences were once again highlighted after the former didn’t allow the latter to wed Captain Peter Townsend since he was a divorcee.

In the documentary “Royals at War,” royal correspondent Victoria Arbiter said that the Queen, who is the head of the Church of England, didn’t give Princess Margaret and Townsend special treatment. Princess Margaret eventually called it quits with Townsend.
