Lady Diana Frances Spencer was just 20 when she married Prince Charles, heir to the throne of Britain, on 29 July 1981. Her beauty and youthful charisma quickly earned Diana the nickname of "the people's princess." She and Charles had two sons, William (b. 1982) and Harry (b. 1984). However, the marriage was troubled almost from the start, and its breakdown was daily fodder for tabloids during the 1990s. Diana and Charles were divorced in 1996 and Diana devoted her life to her two sons and to worldwide charities. She and her boyfriend, Dodi Fayed, were killed in 1997 in a high-speed car crash while being followed by paparazzi in Paris, France. A French investigation showed that their driver, Henri Paul, was intoxicated. There followed years of allegations, led in part by Fayed's father Mohamed Al Fayed, that the pair had been victims of a conspiracy. A three-year British investigation concluded in 2006 that "there was no conspiracy to murder any occupants of that car. This was a tragic accident."
