Lady Jane Grey, traditionally thought to have been born in October 1537, was the daughter of the Duke and Duchess of Suffolk, granddaughter of Mary Tudor and great niece of Henry VIII.
King Edward VI changed the succession decreed by Henry VIII to leave the crown to Lady Jane, therefore ensuring the continuation of the Protestant religion by preventing the succession of the Catholic daughter of Henry VIII, Mary Tudor.
Lady Jane reigned for only nine days in July 1553 before Mary Tudor succeeded to the throne. Lady Jane was imprisoned in the Tower of London until a plot to prevent Mary marrying Philip of Spain, involving the Duke of Suffolk, led to her execution, at the age of 16 or 17, on February 12 1554.
