Princess Diana and Prince Charles's marriage was one of the most tumultuous relationships within the royal family.

After their separation in 1992, it was revealed that Prince Charles had an affair with Camilla Parker Bowles. Sources revealed that on top of the royal couple’s issues, the Duchess of Cornwall also served as one of the reasons behind their split.

But “The Crown” creator Peter Morgan said that Camilla shouldn’t be blamed for the Prince and Princess of Wales’ divorce because she captured Prince Charles’ heart first and not the other way around.

“The assumptions were that he met and fell in love with Diana and that Camilla appeared later. But Diana was the intrusion on a pre-existing romance so we set that up within the season,” Morgan told Express.

Prince Charles and Camilla met each other in 1970, and they fell in love. But just three years later, while the heir to the throne was serving in the Royal Navy, he received a letter from the future Queen saying that she and Andrew Parker Bowles will soon tie the knot.

Royal expert Penny Junor revealed that Prince Charles was heartbroken when he heard the news. The dad of two wrote anguished letters to his nearest and dearest.

“It seemed to him particularly ‘cruel’, he wrote in one letter, that after ‘such a blissful, peaceful and mutually happy relationship’ fate had decreed that it should only last a mere six months,” Junor said.

Five years after Camilla and Andrew tied the knot, Prince Charles started having an affair with the Duchess of Cornwall. But it was only in 1980 that the future King met Princess Diana. The royal couple’s wedding took place in 1981. At that time, Prince Charles and Camilla’s affair continued.

In the Channel 5 documentary “Charles and Di: The Truth Behind Their Wedding,” royal biographer Christopher Wilson said that Princess Diana found a gold bracelet in Prince Charles’ study, and she later found out that it was her future husband’s farewell present to his former flame.

“I think she was very suspicious of anything Camilla. She asked to see what was inside and eventually, she was allowed to have her way. She was absolutely in tears, in a terrible state about it,” he said.
