Prince of Squillace was a noble title created in 1494, by King Alfonso II of Naples (House of Trastamara) for Gioffre Borgia on the occasion of his wedding with the king's daughter Sancia d'Aragona.[1] He was also created Count of Cariati. His second wife was María de Mila y Aragón with whom he had issue. The male line became extinct after the death of the fourth title-holder, Pietro Borgia d'Aragona, the last male heir to hold this title.[1]
Squillace, in Calabria, was the site of an Italo-Norman castle. During the Norman (1130–94) and Swabian (1194–1266) periods of the kingdom of Sicily, it was the seat of a county. After the wars of 1266 and 1282, the county continued to be granted by the Angevin kings of Naples, while the title continued in use in Aragonese Sicily.
