the remaining resistance and made his triumphal entrance in Naples on 26 February 1443, as the monarch of a pacified kingdom. Alfonso then reunited under his dominion the kingdoms of Naples and Sicily, divided since the Sicilian Vespers. After the personal union, he began to call himself Rex Utriusque Siciliae; this was then used by other kings and his successors who ruled over those territories. Art and administration Like many Renaissance rulers, Alfonso V was a patron of the arts. He founded the Academy of Naples under Giovanni Pontano, and for his entrance into the city in 1443 had a magnificent triumphal arch added to the main gate of Castel Nuovo. Alfonso V supplied the theme of Renaissance sculptures over the west entrance. Alfonso was particularly attracted to classical literature. He reportedly brought copies of the works of Livy and Julius Caesar on his campaigns; the poet Antonio Beccadelli even claimed that Alfonso was cured of a disease by the reading of a few pages from Quintus Curtius Rufus' history of Alexander the Great.

Alfonso founded the first university of Sicily, the Siciliae Studium Generale. Later life Alfonso was also a powerful and faithful supporter of Skanderbeg, whom he decided to take under his protection as a vassal in 1451, shortly after the latter had scored his second victory against Murad II. In addition to financial assistance, he supplied the Albanian leader with troops, military equipment, and sanctuary for himself and his family if such a need should arise. This was because in 1448, while Skanderbeg was fighting off the Turkish invasions, three military columns, commanded by Demetrio Reres along with his sons Giorgio and Basilio, had been dispatched to help Alfonso V defeat the barons of
