The Catalan Company, mercenaries led by Roger de Flor and formed by Almogavar veterans of the War of the Sicilian Vespers, were hired by the Byzantine Empire to fought the Turks, defeating them in several battles. After the assassination of Roger de Flor in 1305 by orders of the emperor's son Michael Palaiologos, the Company took revenge sacking Thrace and later Greece, where they founded the duchies of Athens and Neopatras in the name of the King of Aragon. Catalan rule over the Greek lands lasted until 1390.
