Charles, Prince of Wales, first met Diana in November 1977, and after courting her for several years, the two got engaged in February 1981. That July, Diana, who was 20 at the time, married Charles at St Paul's Cathedral. The wedding was televised and had a whopping 750 million viewers, while 600,000 people lined the streets. The couple went on to have two sons, Prince William in 1982 and Prince Harry in 1984.
In August 1996, Charles and Diana divorced after years of tabloid speculation surrounding their marriage, as well as the prince's relationship with Camilla Parker Bowles. That next year, Diana was killed after her car crashed in the Pont de l'Alma road tunnel in Paris, France. She was 36.
It wasn't until 2005 that Prince Charles married Bowles, now the Duchess of Cornwall.
