Nobility, Spanish military and politician. Innico was born in Toledo around 1414. His father was Constable of Castile Ruy López Dávalos, who fell from grace and forced into exile for his support of Henry of Aragon in the dynastic struggles who had opposed him to John II of Castile. The mother of Innico was instead the noblewoman Costanza (or Constanza) de Tovar, daughter of Sancho Fernández de Tovar, lord of Caracena and Cevico de la Torre. Ruy López had taken refuge in the Valencian court of Alfonso V of Aragon and Innico and his brothers Alfonso and Rodrigo were pages in the service of the Aragonese monarch. In 1432 they followed Alfonso, known as "the Magnanimous" (later ascended to the throne of Naples in 1442, as Alfonso I of Naples) in his campaigns in Italy, Sicily and Naples. Innico was decorated as a knight during Alfonso's campaigns in Italy. In 1435 he was taken prisoner following the naval battle of Ponza. Innico, as well as several nobles and members of the royal family (including Alfonso d'Aragona, Enrico and Giovanni), was taken to Milan, where he remained a prisoner of Filippo Maria Visconti. Even after the release of Alfonso and his brothers in 1436, Innico remained at the Milanese court in the service of the Visconti, receiving various bonuses and assignments. In fact, Innico appears to have been appointed chamberlain of Filippo Maria. He was also invested with the ownership of the fiefs of Borgofranco and Scaldasole in 1436. In the service of the Visconti, Innico participated between 1436 and 1438, in the conflicts that saw the Duchy of Milan opposed to the Republic of Venice in the context of the so-called Wars of Lombardy. Innico d'Avalos is believed to be one of the possible authors of the epic-chivalric poem Curial and Güelfa, written in Catalan with various Italianisms. Innico definitively returned to Naples around 1440. Already in 1439, however, he had been recalled by King Alfonso, who had arranged for him, in order to reward him for his services, the marriage with the heiress Enrichetta Ruffo di Calabria. However, this project was not successful due to the interposition of Antonio Centelles, who, although he was originally commissioned by the king to act as an intermediary in the marriage negotiation, ended up marrying Enrichetta himself. The Centelles later also attempted to assassinate Innico. Between 1444 and 1447 we find Innico in Lombardy, Monferrato and Liguria as ambassador of the Aragonese crown. In 1449 he was appointed grand chamberlain of the kingdom of Naples, taking over from Francesco d'Aquino (who died in September of that year). Previously Innico had been Aquino's lieutenant at the Regia Camera della Sommaria. As his lieutenant Innico chose Nicolantonio de 'Monti. In 1442 Alfonso cfavored Innico's engagement with Antonella d'Aquino, nephew of the aforementioned Francesco and countess of Monteoderisio, Antonella exchanged the promise of marriage with Innico I d'Avalos on 11 November 1450 and the marriage between the two was celebrated in 1452. In March 1452 Innico received the Emperor Frederick III of Habsburg, who had come to Gaeta. Frederick had arrived in the kingdom after being crowned emperor in Rome and having married Princess Eleonora d'Aviz. The wedding celebrations took place at the court of the bride's uncle, Alfonso V of Aragon. Later we find Innico lined up alongside King Ferrante of Aragon in the conflict that saw him opposed to the pretender to the Neapolitan throne Giovanni d'Angiò-Valois (Conspiracy of the barons). Innico was taken prisoner in the battle of Sarno (1460) and took part in the battle of Troy in 1462, being awarded the Order of the Ermine in 1463. In March 1464 Innico went to Rome and later to Urbino as a member of a delegation of the king of Naples to Pope Pius II in order to bestow a donation of 60,000 ducats intended to finance a crusade against the Turks. In 1467 Innico was awarded the Order of the Garter. Also during the reign of Ferrante, Innico took part in some minor military operations against the Turks following the battle of Otranto in 1480, and in the military operations in Puglia and Abruzzo against the Papal State and the Republic of Venice conducted as part of the so-called War of Ferrara. Innico died in Naples on 12 September 1484. The following day the funeral took place and his burial took place in the Church of Santa Maria di Monteoliveto.
