Arthur, Prince of Wales (19/20 September 1486 – 2 April 1502) was the eldest son of King Henry VII of England and Elizabeth of York, and an older brother to the future King Henry VIII. He was Duke of Cornwall from birth, and he was created Prince of Wales and Earl of Chester in 1489. As the heir apparent of his father, Arthur was viewed by contemporaries as the great hope of the newly established House of Tudor. His mother was the daughter of the Yorkist king, Edward IV, and his birth cemented the union between the House of Lancaster and the House of York.
Plans for Arthur's marriage began before his third birthday. At the age of eleven, he was formally betrothed to Catherine of Aragon, a daughter of the powerful Catholic Monarchs in Spain, in an effort to forge an Anglo-Spanish alliance against France and Scotland. Arthur was well educated and was in good health for the majority of his life. Soon after his marriage to Catherine in 1501, the couple took up residence at Ludlow Castle in Shropshire, where Arthur died six months later, possibly from the sweating sickness, which Catherine survived. Catherine later firmly stated that the marriage had not been consummated.
