  Research Notes:

The Crónica de San Juan de la Peña names "el primero Alfonso et el otro Jayme et el otro Frederico" as the sons of King Pedro and his wife Constanza. The Historia Sicula of Bartolomeo di Neocastro names "Alfonsus, Elisabeth regina Portugalli…Rex Iacobus, Dominus Fridericus, domina Violanta et dominus Petrus" as the children of "Petro regi Aragonum" and his wife. The Chronicle of Ramon Muntaner names "Alfonse, Jacques, Frédéric et Pierre" as the four sons of "le seigneur infant Pierre" and "la fille de Mainfroi roi de Sicile…Constance".

He succeeded his father in 1285 as ALFONSO III "el Liberal" King of Aragon and Valencia, Count of Barcelona. After he succeeded, he continued his father’s campaign against the Balearic Islands to punish his uncle Jaime II King of Mallorca, for the latter’s support of the French during the dispute over Sicily. He recaptured Mallorca city and Ibiza 1286, and captured Minorca from the Moors Jan 1287. However, diplomatic tensions with France and the Papacy worsened, and eventually Alfonso was forced to withdraw his support for his brother at Tarascon Feb 1291 as the price for lifting sanctions. He was forced to grant further privileges to the Aragonese Union 1287 (“el privilegio de la unión”), after the latter invaded Valencia and placed an embargo on royal revenues.

The Crónica de San Juan de la Peña records the death in 1292 of King Alfonso aged 27 and his burial "en el monasterio de los frayres menores de Barchinona". The Chronicle of Ramon Muntaner records the death of King Alfonso, dated to 1291, his burial "à l´ordre des frères mineurs à Barcelona", and adds that "il était parfaitement vierge, n´ayant jamais approché de femme". 1
