In 1194, Frederick II, took control of the region, after inheriting the Kingdom from his mother Constance, Queen of Sicily. He created a kingdom that blended cultures, philosophy and customs and would build several castles while fortifying existing ones which the Normans previously constructed. After the death of Frederick II in 1250, Calabria was controlled by the Capetian House of Anjou, under the rule of Charles d’Anjou after being granted the crown of the Sicilian Kingdom by Pope Clement IV. In 1282, under Charles d’Anjou, Calabria became a domain of the newly created Kingdom of Naples, and no longer of the Kingdom of Sicily, after he lost Sicily due to the rebellion of the Sicilian Vespers. During the 14th century, would emerge Barlaam of Seminara who would be Petrarch's Greek teacher and his disciple Leonzio Pilato, who would translate Homer's works for Giovanni Boccaccio.
