Arthur, Prince of Wales, was the eldest son of Henry VII and Elizabeth of York and the first Tudor heir to the English throne. In 1501 he married Catherine of Aragon, strengthening the alliance between England and Spain, but died at Ludlow only a few months later, probably from an infectious illness. The later dispute over whether the marriage had been consummated became central to Henry VIII’s attempt to annul his own marriage to Catherine.
Arthur is a major figure in Philippa Gregory’s The Constant Princess and in Alison Weir’s Katherine of Aragon, The True Queen, both of which imagine Catherine’s brief first marriage and the promises or secrets that may have followed it. Because contemporary evidence about the couple’s private life is sparse, novelists have considerable freedom. Their interpretations directly shape how readers understand Catherine’s later resistance to Henry VIII.
