Why lady Jane grey die?

Answer 1

Lady Jane Grey died because of her parents and her uncle in law John Dudley or Northumberland . She was the great-granddaughter of King Henry VIII and when the son of Henry VIII died he named her as the Queen instead of his two half sisters Mary and Elizabeth. Mary did not like this and 9 days after Jane became Queen Mary declared herself Mary I and over threw Jane. Jane was throw into the tower of London and was executed a couple of months later. Mary then had Jane and her husband executed be Jane's father rebelled against Mary and she thought that with out Jane and her most likely revengful husband on the scene she could rule in peace.
