Arthur, Prince of Wales

The eldest child of Henry VII and Elizabeth of York, Arthur Tudor was born at Winchester on 20 September 1486, less than a year after his father's victory at Bosworth Field. His birth joined the rival claims of Lancaster and York in a single heir, and his name, chosen with deliberate reference to the legendary British king, advertised the ambitions of the new dynasty. He was created Prince of Wales in 1489 and given a careful humanist education under tutors including Bernard André and Thomas Linacre.

Arthur's marriage was the centrepiece of his father's diplomacy. Under the Treaty of Medina del Campo, concluded in 1489, he was betrothed in infancy to Catherine of Aragon, daughter of Ferdinand II of Aragon and Isabella I of Castile, linking the Tudors to the house of Trastámara, then among the most powerful in Europe. The couple corresponded in Latin for years before they met. They were married at Old St Paul's Cathedral in London on 14 November 1501, an occasion of elaborate pageantry intended to display the dynasty's security and standing.

Shortly after the wedding the young couple travelled to Ludlow Castle on the Welsh border, where Arthur, as Prince of Wales, nominally presided over the Council of Wales and the Marches. In March 1502 both husband and wife fell seriously ill, possibly with the sweating sickness then present in the region. Catherine recovered; Arthur died on 2 April 1502, aged fifteen. He was buried in Worcester Cathedral, where his chantry chapel survives.

His death redirected the course of the dynasty. His younger brother Henry became heir apparent and succeeded in 1509 as Henry VIII, marrying the widowed Catherine of Aragon under a papal dispensation. The question of whether Arthur's brief marriage had been consummated — Catherine consistently maintained that it had not — later became central to Henry VIII's effort to annul his own marriage in the late 1520s, a dispute that precipitated England's break with Rome. Arthur thus shaped the English Reformation more through his early death than through anything he accomplished in life, and his loss left Henry VII with only one surviving son on whom the Tudor succession depended.
