Diana, Princess of Wales (born Diana Frances Spencer; 1 July 1961 – 31 August 1997), was a member of the British royal family. She was the first wife of King Charles III (then Prince of Wales) and mother of Prince William and Prince Harry.
As Princess of Wales, Diana undertook royal duties on behalf of Elizabeth II and represented her at functions across the Commonwealth realms. She was celebrated in the media for her unconventional approach to charity work. Her patronages were initially centred on children and the elderly, but she later became known for her involvement in two particular campaigns: one involved the social attitudes towards and the acceptance of AIDS patients, and the other for the removal of landmines, promoted through the International Red Cross. She also raised awareness and advocated for ways to help people affected by cancer and mental illness. Diana was initially noted for her shyness, but her charisma and friendliness endeared her to the public and helped her reputation survive the acrimonious collapse of her marriage.
