The Duchy of Athens was a Latin or Frankish state in Greece that existed from 1205 to 1458 CE. It was created in the aftermath of the Fourth Crusade (1202-1204 CE) and would be ruled for the majority of its history by the Burgundian de la Roche family, the Catalans under the rule of the kings of Sicily, and the Florentine Acciaioli family. As a Latin state in Greece, it was closely connected to its neighboring states as well as the rulers of southern Italy and imposed feudal law on its small territory in Attica, Boeotia, and later Thessaly.
