06/27/1458 AD died
Alfonso, by formally submitting his reign to the Papacy, obtained the consent of Pope Eugene IV that the Kingdom of Naples would go to his illegitimate son, Ferdinand.
He died in Castel dell'Ovo, while he was planning the conquest of Genoa.
At the time, Alfonso was at odds with Pope Callixtus III, who died shortly afterwards.[citation needed] Alfonso's Iberian possessions had been ruled for him by his brother, who succeeded him as John II of Aragon. Sicily and Sardinia were also inherited by John II.
