In 1266, conflict between the Hohenstaufen house and the Papacy led to Sicily's conquest by Charles I, Duke of Anjou. Opposition to French officialdom and taxation combined with incitement of rebellion by agents from the Byzantine Empire and the Crown of Aragon led to the Sicilian Vespers insurrection and successful invasion by king Peter III of Aragon in 1282. The resulting War of the Sicilian Vespers lasted until the Peace of Caltabellotta in 1302, dividing the old Kingdom of Sicily in two.
