Episode Three
The Shadow of the King: Following the death of Henry VIII and the Act of Succession of 1543, which allowed all three of his children to rule. Edward VI, Mary I and Elizabeth I.
Mary I
(18 February 1516 – 17 November 1558), was Queen of England and Queen of Ireland from 19 July 1553 until her death. She was the oldest daughter of Henry VIII and Katherine of Aragon. The fourth crowned monarch of the Tudor dynasty, she is remembered for restoring England to Roman Catholicism after succeeding her short-lived half brother, Edward VI, to the English throne. In the process, she had almost 300 religious dissenters burned at the stake in the Marian Persecutions, earning her the sobriquet of "Bloody Mary". Her re-establishment of Roman Catholicism was reversed by her successor and half-sister, Elizabeth I.
Mary was the only child of Henry VIII and his first wife Catherine of Aragon to survive infancy. Her mother had many miscarriages, and Mary had been preceded by a stillborn sister and three short-lived brothers, including Henry, Duke of Cornwall. Through her mother, she was a granddaughter of Ferdinand II of Aragon and Isabella I of Castile. She was born at the Palace of Placentia in Greenwich, London. She was baptised with Thomas Cardinal Wolsey standing as her godfather. Mary was a sickly child who had poor eyesight, sinus conditions and bad headaches. At the age of 6, she suffered from a brain tumor. It was removed, though this caused her to suffer from epileptic seizures. John Hussey, 1st Baron Hussey of Sleaford was her Chamberlain, and his wife, Lady Anne, daughter of George Grey, 2nd Earl of Kent, was one of Mary's attendants.
