Jane was the eldest daughter of Henry Grey, marquis of Dorset, later duke of Suffolk, and a cousin of Edward VI. The duke of Northumberland planned to use her to seize the succession when Edward should die. Against her own wishes, she was married on 21 May 1553 to Guildford Dudley, fourth son of Northumberland. After Edward's death on 6 July 1553, she was proclaimed queen. Mary Tudor's supporters rallied and on 19 July Jane's father admitted defeat. Lady Jane's reign had lasted a mere nine days. She was held in the Tower and executed on 12 February 1554.
