On 20 November 1947, seventy-eight years ago, Princess Elizabeth married Lieutenant Philip Mountbatten, newly appointed Duke of Edinburgh, in Westminster Abbey, London. At the time, she was still Her Royal Highness Princess Elizabeth, and he was Lieutenant Philip Mountbatten, HRH The Duke of Edinburgh. Years later, she would become Queen Elizabeth II, while he would be remembered globally as Prince Philip, Duke of Edinburgh — one of the longest-serving royal consorts in British history. #london
