How old was Henry VIII when he married his first wife Catherine of Aragon?

Henry VIII (28 June 1491 – 28 January 1547) was King of England from 1509 until his death in 1547. Henry is best known for his six marriages, and, in particular, his efforts to have his first marriage (to Catherine of Aragon) annulled. His disagreement with Pope Clement VII on the question of such an annulment led Henry to initiate the English Reformation, separating the Church of England from papal authority. He appointed himself the Supreme Head of the Church of England and dissolved convents and monasteries, for which he was excommunicated.

Henry VII died on 21 April 1509, and the 17-year-old Henry succeeded him as king. Soon after his father's burial on 10 May, Henry suddenly declared that he would indeed marry Catherine, leaving unresolved several issues concerning the papal dispensation and a missing part of the marriage portion. The new king maintained that it had been his father's dying wish that he marry Catherine. Whether or not this was true, it was certainly convenient. Emperor Maximilian I had been attempting to marry his granddaughter (and Catherine's niece) Eleanor to Henry; she had now been jilted. Henry's wedding to Catherine was kept low-key and was held at the friar's church in Greenwich on 11 June 1509.
