Lady Jane Grey

Lady Jane Grey (c. 1537 – 12 February 1554), later known as Lady Jane Dudley (after her marriage) and as the "Nine Days' Queen", was an English noblewoman who claimed the throne of England and Ireland from 10 July until 19 July 1553. Mary initially spared her life; however, Jane soon became viewed as a threat to the Crown when her father, Henry Grey, 1st Duke of Suffolk, became involved with Wyatt's rebellion against Queen Mary's intention to marry Philip II of Spain. Jane and her husband were executed on 12 February 1554.
