Throughout her long reign, Queen Elizabeth II has been supported in her duties by her husband, Prince Philip, Duke of Edinburgh. Prince Philip promised to help the Queen on the day of her Coronation. The Queen was also helped by her mother Queen Elizabeth, known as "The Queen Mother", who lived to be 101 years old, and stayed very active in her old-age. The Queen is the patron of many organisations and charities. She has many invitations and official duties. Many of the duties have been shared by other members of the Royal Family, who have also become patrons of many organisations.
