Prince William and Prince Harry's relationship took a turn for the worse after the Duke of Sussex fled the U.K. — and Harry and William's dynamic was severely damaged by the Sussexes' 2021 tell-all interview with Oprah Winfrey and Spare.
Since moving to California, Harry's distance from his relatives quickly became visible. The veteran wasn't invited to his father's Trooping the Colour, and he was seated away from his brother, sister-in-law and niece and nephew during King Charles' coronation.
Despite the schism being made known after Megxit, a palace aide told author Tina Brown that the damage began on William's wedding day.
"Though they were still 'incredibly close, living next door to each other [at Kensington Palace], sharing the same office, and hanging out a lot," Brown wrote in The Palace Papers.
"[Harry] mourned his us-against-the-world bond with William," Brown added.
As William joined Kate's family, Harry slowly began to feel "displaced."
"Bucklebury [The Middleton's home] world bored Harry to tears," Brown wrote. "[William and Kate] had a tight unit, and William [became] a full-on Windsor country bumpkin."
Harry hinted at struggling with William becoming a husband in his memoir.
"The brother I'd escorted into Westminster Abbey that morning was gone — forever," Harry shared. "Who could deny it? He'd never again be first and foremost Willy. We'd never again ride together across the Lesotho countryside with capes blowing behind us. We'd never again share a horsey-smelling cottage while learning to fly. Who shall separate us? Life, that's who."
"And I recall Willy walking her back up the aisle, and as they disappeared through the door, into the carriage that would convey them to Buckingham Palace, into the eternal partnership they'd pledged, I recall thinking: Goodbye," he wrote.
"There has always been this competition between us, weirdly," Hary explained. "I think it really plays into or was played by, the 'heir/spare.'"
