Lady Jane Grey

Lady Jane Grey (1536/1537 – 12 February 1554), also known as Lady Jane Dudley after her marriage, and nicknamed the "Nine Days Queen", was an English noblewoman who was proclaimed Queen of England and Ireland on 10 July 1553 and reigned until she was deposed by the Privy Council of England, which proclaimed her cousin, Mary I, as the new Queen on 19 July. Jane was later beheaded for high treason.

Jane was the great-granddaughter of Henry VII (through his youngest surviving daughter, Mary Tudor), the grandniece of Henry VIII, and the first cousin once removed of Edward VI, Mary I, and Elizabeth I. Under the will of Henry VIII, Jane was in line to the throne after her cousins. She had a humanist education and a reputation as one of the most learned young women of her day. In May 1553, she was married to Lord Guildford Dudley, a younger son of Edward VI's chief minister, John Dudley, Duke of Northumberland. In June, the dying Edward VI wrote his will, nominating Jane and her male heirs as successors to the Crown, in part because his half-sister Mary was Catholic, whereas Jane was a committed Protestant and would support the reformed Church of England, whose foundation Edward laid. The will removed both of his half-sisters, Mary and Elizabeth, from the line of succession because of their illegitimacy, subverting their lawful claims under the Third Succession Act. Through the Duke of Northumberland, Edward's letters patent in favour of Jane were signed by the entire privy council, bishops, and other notables.

After Edward's death, Jane was proclaimed queen on 10 July 1553 and awaited coronation in the Tower of London. Support for Mary grew rapidly, and most of Jane's supporters abandoned her.
