Queen Elizabeth The Queen Mother [SEP] Widowhood
Shortly after George VI's death, Elizabeth began to be styled as "Her Majesty Queen Elizabeth The Queen Mother" because the normal style for the widow of a king, "Queen Elizabeth", would have been too similar to the style of her elder daughter, now Queen Elizabeth II. Popularly, she became the "Queen Mother" or the "Queen Mum". She was devastated by her husband's death and retired to Scotland. However, after a meeting with the Prime Minister, Winston Churchill, she broke her retirement and resumed her public duties. Eventually she became just as busy as queen mother as she had been as queen consort.
