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.
Tower Green Tower Green is a space within the Tower of London, a royal castle in London, where two English Queens consort and several other British nobles were executed by beheading. It was considered more dignified for nobility to be executed away from spectators, and Queen Anne Boleyn and Lady Jane Grey were among the nobility beheaded here. Queen Victoria asked for information on the exact location where the executions took place and had some granite paving laid to mark the spot. However, it is unclear whether the location is indeed correct because other sources place it on the current parade ground between the White Tower and the entrance to the current Waterloo Barracks.
