Although Prince William was heartbroken after learning Prince Charles and Princess Diana planned to end their marriage, the young royal was reportedly the reason why the divorce was able to move forward after negotiations hit a wall.

Princess Diana and Prince Charles finalized their divorce in 1996 when Prince William was in his early teens. However, when the couple separated in 1992, their eldest son was eager to stick by his mother’s side and protect her during the emotional time in her marriage.

The documentary “Prince William: Royalty In My Family,” claims the then-teen provided comfort to Diana, who wanted to keep her HRH (Her Royal Highness) title despite Charles’ insistence that she lose it following their divorce. “You’ll still be mummy,” the narrator claimed was the Duke of Cambridge’s words to reassure his mother of her decision to let it go.

The documentary suggests Willam encouraged Princess Diana to agree to the terms of her divorce settlement with Charles in order to legally dissolve her marriage once and for all.

“It’s believed that William later advised her to accelerate her divorce proceedings by agreeing to be stripped of her royal title,” the narrator stated.

As a way to cheer Diana up over the loss of her husband and title, Prince William reportedly booked a reservation for his mother at her favorite restaurant.

According to the documentary, Princess Diana often “relied” on William for “comfort and advice” as she struggled to let go of her marriage to Prince Charles. A year after the pair finalized their divorce, Diana died in a tragic car crash in Paris.
