Diana was born into the British nobility and grew up close to the royal family on their Sandringham estate. In 1981, while working as a nursery teacher's assistant, she became engaged to Prince Charles, the eldest son of Queen Elizabeth II. Their wedding took place at St Paul's Cathedral in 1981 and made her Princess of Wales, a role in which she was enthusiastically received by the public. The couple had two sons, William and Harry, who were then second and third in the line of succession to the British throne. Diana's marriage to Charles, however, suffered due to their incompatibility and extramarital affairs. They separated in 1992, soon after the breakdown of their relationship became public knowledge. The details of their marital difficulties became increasingly publicised, and the marriage ended in divorce in 1996.
