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]
