Jean de Montfort (died December 1300) was count of Squillace, seigneur of la Ferté-Alais, of Bréthencourt, and of Castres-en-Albigeois from 1270 to 1300.
This was also a period of transmission: the Roman patrician Boethius (c. 480–524) translated part of Aristotle's logical corpus, thus preserving it for the Latin West, and wrote the influential literary and philosophical treatise De consolatione Philosophiae; Cassiodorus (c. 485–585) founded an important library at the monastery of Vivarium near Squillace where many texts from Antiquity were to be preserved.
During the Kingdom of Sicily, with the lordship of Roger of Lauria, Squillace passed first to Robert of Anjou and to the counts of Monfort, then for one hundred and fifty years the city was ruled by the counts of Marzano.
On 11 September 1478 in Milan, she married Frederick of Aragon, Prince of Squillace, Altamura and Tarento (1452–1504), the future King Frederick IV of Naples.
