It’s hard to imagine the royal family without Prince Harry.

After all, the Duke of Sussex is currently considered the most popular member of the royal clan.

But long before Harry earned his Duke title after marrying former actress Meghan Markle, the young prince considered renouncing his royal status.

“Harry was a reluctant royal,” royal biographer Penny Juror claimed in the new documentary Meghan Markle: American Princess.

“I think there was a real danger at one time that Harry might turn his back on his royal life and his royal responsibilities and go and live somewhere else quietly,” she added.

As well all know, in the end, Harry stayed a royal – but there was just one person who convinced him to stay.

According to CBS This Morning host Gayle King, who also chimed in during the documentary, Harry decided not to abandon his royal duties for the sake of his grandmother, the Queen.

Prince Harry's decision to renounce his status came about around the same time he developed a reputation for being rebellious.

From his infamous Las Vegas trip in 2012 to the time he dressed as a Nazi in 2005, Harry was subject to a lot of negative media attention.

Despite it all, however, the Queen has always had a close relationship with Harry and in the end, she forgave him.

While Prince William is said to have a more professional relationship with his grandmother, Prince Harry's relationship to the Queen is a much more typical grandmother-to-grandson relationship.

"Behind closed doors, she's our grandmother, it's a simple as that," Prince Harry said in a 2012 interview on the ABC.

"I still think she's just my grandmother, really," Prince William added in the interview.

"I'm probably a bit of a cheeky grandson, like my brother as well. We both take the mickey a bit too much. But I remember always having a healthy respect for my grandmother."

The Duchess of Sussex, Meghan Markle, has also formed a good relationship with the Queen in her short time as a royal.

"It's incredible, I think, you know, to be able to meet her through his lens, not just with his honour and respect for her as the monarch, but the love that he has for her as his grandmother," Meghan said in her post-engagement interview with the BBC.

"All of those layers have been so important for me so that when I met her I had such a deep understanding and of course incredible respect for being able to have that time with her," she continued.

"She's an incredible woman."
