Prince Charles has numerous achievements in his life as a royal. But, royal biographers have claimed the public will not remember him for these things as Princess Diana’s legacy lingers over him.

Speaking to People, Andrew Morton stated that the future King of the United Kingdom “will be remembered for one thing," and that is his failed “fairy-tale marriage” to the Princess of Wales. He added that this is the royal’s “tragedy,” noting this will be the case “whatever he does, whatever he says, [and] however he behaves.”

The royal biographer, who authored “Diana: Her True Story,” continued that the Prince of Wales’s “life has been defined by his marriage.” He also asserted that “it will always haunt him,” adding that he is “remembered for his first wife” much like Henry VIII, who, as Morton said, “is remembered for his six wives.”

In the same exchange, the magazine noted that royal biographer Ingrid Seward has similar thoughts about Prince Charles. She stated, “The ghost of [Princess] Diana really stalked him at every turn.”

The Prince and Princess of Wales got married in 1981. Insider said the royal event was “then called the ‘wedding of the century,’” adding that about 750 million people tuned in to witness them tie the knot.

The figure is reportedly in addition to the over 600,000 spectators who went out of their homes and lined the streets of London on the day of the royal wedding.

In the years that followed, the Heir Apparent and his first wife welcomed their two sons, Prince William and Prince Harry.

The publication noted that the then-couple appeared to have a “happy marriage” from the outside. But, inside, the Princess of Wales was reportedly in “turmoil” as she struggled with “marital troubles” and an “eating disorder.”

It is believed that Prince Charles and Camilla Parker Bowles began their affair in 1986. Their respective spouses, Princess Diana and Andrew Parker Bowles, allegedly knew about it.

Six years later, the Wales couple formally separated from one another. They continued to go on royal engagements, although they did them separately.

Prince Charles and Princess Diana ultimately decided to divorce in 1996. It was a year after Camilla Parker Bowles and Andrew Parker Bowles ended their marriage, according to Vanity Fair.

It was only in 1999, though, that the Prince of Wales and the now-Duchess of Cornwall made a joint public appearance after attending a birthday party at the Ritz Hotel in London.

In 2005, the future King and Camilla Parker Bowles tied the knot in a civil ceremony at Windsor Guildhall.
