The terminally ill Edward VI is persuaded by his chief minister John Dudley, Duke of Northumberland, to rule that his successor should be Lady Jane Grey, whose grandmother was Henry VIII's younger sister and whose husband was Northumberland's son Guildford. This was intended to ensure that the crown remained within the grasp of a Protestant succession, preventing Edward's Catholic sister Mary from undoing all his reforming work after his death.
