Prince William and Kate Middleton’s wedding may not have pushed through if Prince Harry didn’t agree to be his brother’s best man.

According to The Times, the Duke of Cambridge was adamant about giving Prince Harry an important role even though it was a break from tradition.

In the past, male royals don’t normally ask their brothers or close male friends to be their best man. Rather, they only ask them to be their supporters.

On his wedding day, Prince William said that he chose Prince Harry as his best man because he had more relevance in his life than any other alternative. After all, the royal siblings were very close to each other.

Years later, the Duke of Sussex returned the favor to Prince William by asking him to be his best man. Prince William agreed but reports claimed that at that time, the royal siblings were already having a falling out.

Prior to Prince Harry and Meghan Markle’s wedding, Prince William reportedly warned his brother about tying the knot so soon. The Duke of Cambridge was concerned over the fact that the Duke and Duchess of Sussex didn’t know each other very well.

However, Prince Harry still decided to push through with his and Markle’s wedding. And he and Prince William appeared to have a united front on the Duke of Sussex’s special day.

Years later, the royal siblings’ feud reportedly worsened. Earlier this year, a source told People that the Duke of Cambridge became more upset with his brother after Prince Harry decided to relocate to Canada.

“They didn’t leave on good terms by any means, but they are both relieved that it’s over. Perhaps Meghan and Harry didn’t think things through exactly as they could have, but they wanted to be happy. Who can blame them for that?” the source said.

Prince William and Prince Harry used to rely on each other for everything especially while they were growing up. After all, they were still very young when they lost their mom, Princess Diana to a tragic car accident.

The Duke of Cambridge was also the one that encouraged Prince Harry to seek professional help for his mental health issues. It was only a few years ago that the Duke of Sussex started talking about his struggles following the Princess of Wales’ death.

But more recent reports claimed that Prince William and Prince Harry have already started talking again.
