Prince of Squillace
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. 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.
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.
