Prince Williamthought the moment “was an important show of unity at an incredibly difficult time for the family,” a royal source told PEOPLE.

A palace insider echoed: “It’s such an extraordinary historical moment and also a deeply personal one for the family that you’d hope and think that all members of the family would unite and support [the King] especially. And perhaps some of those wounds can be healed in the process.”

Relations have been strained between the Duke and Duchess of Sussex and the rest of the royal family in recent years, though grieving the Queen could bring them back together again.
