Which monarchy had this English peeress executed whose adult life is depicted in the 2014 historical novel The King's Curse?
Margaret Pole, Countess of Salisbury Margaret Pole, Countess of Salisbury (14 August 1473 – 27 May 1541), was an English peeress. She was the daughter of George, Duke of Clarence, the brother of kings Edward IV and Richard III. Margaret was one of two women in 16th century England to be a peeress in her own right with no titled husband. One of the few surviving members of the Plantagenet dynasty after the Wars of the Roses, she was executed in 1541 at the command of Henry VIII, who was the son of her first cousin Elizabeth of York. Pope Leo XIII beatified her as a martyr for the Catholic Church on 29 December 1886.
Sophia of Hanover Sophia of the Palatinate (commonly referred to as Sophia of Hanover; 14 October 1630 – 8 June 1714) was the Electress of Hanover from 1692 to 1698. As a granddaughter of James VI and I, she became heir presumptive to the crowns of the Kingdom of England and the Kingdom of Ireland under the Act of Settlement 1701. After the Acts of Union 1707, she became heir presumptive to the unified throne of the Kingdom of Great Britain. She died less than two months before she would have become queen, and her claim to the throne passed on to her eldest son, George Louis, Elector of Hanover, who ascended as George I on 1 August 1714 (Old Style).
