The Queen has shown a very strong sense of duty, ever since she was a girl. Her father, King George VI, was not meant to be king. Her uncle became king when her grandfather died. But he fell in love with an American woman who was divorced, and that wasn't allowed. So he had to give up being king very shortly after ascending. George VI didn't want to be king, because he was quite nervous and had a stammer. However, Elizabeth's grandfather said that he didn't think her uncle was very good as a king, and wanted George to reign, then Elizabeth. From the moment she realised that one day she would be Queen, she became very interested in her duties and did all she could to help her father. Her promise to serve her people all her life has always been very important to her. Some people think that now that she is old, perhaps she will retire ("abdicate") and let her son Prince Charles take over. People who know her well, including Prince Charles, have said that this will never happen.
