As for the way they honored their mother this week, royal historian Robert Lacey told PEOPLE that the brothers"demonstrated a constructive way of dealing with differences."

“[They were] not sweeping [their differences] under the carpet but acknowledging more important things and doing that in a way that warmed everyone’s heart,” said Lacey, who hasexplored the tensionsbetween William, 39, and Harry, 36, in his bookBattle of Brothers.

Added Ken Wharfe, who led the personal protection of Princess Diana and her sons for several years in the late ’80s: “It was their idea and it was a joint effort.”
