Prince Charles and Lady Diana Spencer married at St Paul’s Cathedral in London on Wednesday, July 29, 1981. The ceremony was one of the decade’s biggest events—and for good reason. Queen Elizabeth II’s eldest son Charles was (and still is, of course) first in line to the throne, which made the day a landmark moment in the life of the presumptive future King of England.
With the early days of Charles and Diana’s relationship now immortalized in Netflix’s The Crown, here are some more facts and figures behind one of the 20th century’s most famous relationships.
1. Prince Charles met Diana while he was dating her sister.
Charles was romantically involved with Diana’s elder sister, Sarah Spencer (now Lady Sarah McCorquodale) when he first met his future bride-to-be. His and Sarah’s relationship wasn’t quite as harmonious as it’s portrayed in The Crown; Sarah later said that she wouldn’t marry Charles whether “he were the dustman or the King of England.” Nevertheless, it’s through Sarah that Charles was first introduced to Diana while on a grouse hunt at Althorp House, the Spencer family’s ancestral home, in 1977. Diana was just 16 at the time—six years younger than Sarah, and more than 12 years younger than Charles.
2. It was love at first sight for Charles and Diana …
Charles seems to have taken an immediate shine to Diana, telling The Daily Telegraph in 1981 that he remembered thinking, “what a very jolly and amusing and attractive 16-year-old she was” after they first met. For her part, Diana reportedly told friends that she was destined to marry Charles after her first encounter with him—adding (not so prophetically) that “he’s the one man on the planet who’s not allowed to divorce me.” (Divorce laws for royals used to be a lot more stringent than they are today, and weren’t fully relaxed until 2002.)
3. … or maybe it wasn’t love at first sight for Charles and Diana.
Long after their relationship had broken down, Diana revisited her first impression of Charles—this time with the benefit of hindsight. In 1992, she told her biographer Andrew Morton that her actual first thought after meeting the future king was, “God, what a sad man.” Ouch.
4. It took a while for things to get going between Charles and Diana.
No matter what their first impressions were, it took a long time for Charles and Diana to become a couple. It wasn’t until 1980, shortly before Diana’s 19th birthday, that the couple finally got together. In the three years in between, Charles’s relationship with Sarah Spencer fizzled out, after which he reportedly proposed to Amanda Knatchbull, the granddaughter of Earl Mountbatten, his mentor. Knatchbull turned him down.
At the same time, rumors began swirling that Charles was still romantically involved with his long-term sweetheart Camilla Shand, despite her having married Brigadier Andrew Parker Bowles in 1973. (Camilla is now the Duchess of Cornwall, Charles’s second wife. The couple tied the knot in 2005.)
