John II of Aragon
King of Aragon from 1458 to 1479
John II (Spanish: Juan II, Catalan: Joan II, Aragonese: Chuan II and Basque: Joanes II; 29 June 1398 – 20 January 1479), called the Great (el Gran) or the Faithless (el Sense Fe), was King of Aragon from 1458 until his death in 1479. As the husband of Queen Blanche I of Navarre, he was King of Navarre from 1425 to 1479. John was also King of Sicily from 1458 to 1468.
Biography
John was born at Medina del Campo (in the Crown of Castile), the son of King Ferdinand I of Aragon and Eleanor of Alburquerque. In his youth he was one of the infantes (princes) of Aragon who took part in the dissensions of Castile during the minority and reign of John II of Castile. Until middle life he was also lieutenant-general in Aragon for his brother and predecessor Alfonso V, whose reign was mainly spent in Italy. In his old age he was preoccupied by incessant conflicts with his Aragonese and Catalan subjects, with Louis XI of France, and in preparing the way for the marriage of his son Ferdinand with Isabella I of Castile which brought about the union of the crowns of Aragon and Castile and which was to create the Monarchy of Spain. His troubles with his subjects were closely connected with tragic dissensions within his own family.
John was first married to Blanche I of Navarre of the House of Évreux. In 1432, John II appointed Juan Vélaz de Medrano, Lord of Igúzquiza and Learza, as his royal chamberlain, a position he had previously held under Blanche's late father, Charles III of Navarre.

Public reputation and documentary evidence do not always develop together; absence from a summary is not evidence of historical absence. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
