Catherine of Aragon is married by proxy to Arthur, Prince of Wales. Catherine is 13 and Arthur is 12.

Catherine of Aragon was Queen of England as the first wife of King Henry VIII from their marriage on 11 June 1509 until its annulment on 23 May 1533. She had previously been Princess of Wales while married to Henry's elder brother, Arthur, Prince of Wales, for a short period before his death.

A proxy wedding or proxy marriage is a wedding in which one or both of the individuals being united are not physically present, usually being represented instead by other persons (proxies). If both partners are absent, this is known as a double proxy wedding.

Arthur, Prince of Wales, 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.
