Prince William and Prince Harry were confused and shocked that the public grieved for the death of their mom, Princess Diana.

The Duke of Cambridge was only 15 years old, while the Duke of Sussex was 12 when their mother, Princess Diana, died in a car crash. According to the two princes, it was heartbreaking, but they were also wondering why the people were so affected by their mom’s death.

“I couldn’t understand why everyone wanted to cry as loud as they did, and show such emotion as they did when they didn’t really know our mother,” Prince William said about the funeral procession. “I did feel a bit protective at times about her. I was like, 'you didn’t even know her.' Why and how are you so upset?”

Prince William confessed that looking back he learned to understand what Princess Diana gave to the world and to a lot of people. That’s when he understood why they grieved for Princess Diana.

“The way that people were grabbing us and pulling us into their arms… I don’t blame anybody for that, of course I don’t, but it was those moments that were quite shocking,” Prince Harry recalled.

In the photos during Princess Diana’s funeral, Prince Philip, Prince William, Earl Spencer, Prince Harry and Prince Charles can be seen walking behind the People’s Princess’ coffin. According to Ingrid Seward’s book “My Husband And I: The Inside Story of the Royal Marriage,” Princess Diana’s brother believed that he should only be the one to walk behind her coffin, but the royal family disagreed.

Prince William also refused to join, but Prince Charles pleaded him to do it as it would be utterly wrong for him not to accompany them. The Duke of Cambridge agreed with a condition – that Prince Philip had to join them and walk beside him. Prince William confessed that walking behind his mom’s coffin was “one of the hardest things” he had to do.

Prince Harry shared the same sentiment. In an interview with Newsweek, he revealed that it was not easy because his mother just died and he had to walk a long way behind her coffin surrounded by thousands of people watching him while millions did on television.

“I don’t think any child should be asked to do that, under any circumstances. I don’t think it would happen today,” Prince Harry said.
