Alonso was more a politician than a clergyman. He was five years old when his father Ferdinand and grandfather King
John II of Aragon decided he would enter the Church. When
Juan de Aragón, Archbishop of Zaragoza and John's illegitimate son, died in 1475, John and Ferdinand chose Alonso to succeed him.
Pope Sixtus IV thought that he was too young and appointed Cardinal
Ausiàs Despuig. In 1478, Sixtus yielded to their pressure, deposed Ausias, and appointed Alonso as archbishop on 14 August. However, he was not ordained as a priest until 7 November 1501, a day before being ordained as a bishop. On 23 January 1512, Alonso was also appointed Archbishop of Valencia. He was enthroned as such on 4 April 1512. == Political career ==
