Diana, Princess of Wales, was a member of the British royal family. She was the first wife of Charles III and mother of Princes William and Harry. Her activism and glamour, which made her an international icon, earned her enduring popularity. Diana was born into the British nobility and grew up close to the royal family, living at Park House on their Sandringham estate. In 1981, while working as a nursery teacher's assistant, she became engaged to Charles, the eldest son of Elizabeth II. Their wedding took place at St Paul's Cathedral in July 1981 and made her Princess of Wales, a role in which she was enthusiastically received by the public.
