State in southern Greece (1205–1458)

The Duchy of Athens was one of the Crusader states set up in Greece after the conquest of the Byzantine Empire during the Fourth Crusade as part of the process known as Frankokratia, encompassing the regions of Attica and Boeotia. Its history can be divided into three periods: the rule of the French de la Roche dynasty (1205–1311), the Catalan dominion (1311–1388) and finally the rule of the Italian Acciaioli (1388–1458), which came to a close with the Ottoman conquest in 1458.

Duchy of Athens in Depth

History

The first duke of Athens (as well as of Thebes, at first) was Otto de la Roche, a minor Burgundian knight of the Fourth Crusade. Although he was known as the "Duke of Athens" from the foundation of the duchy in 1205, the title did not become official until 1260. Instead, Otto proclaimed himself "Lord of Athens" (in Latin Dominus Athenarum, in French Sire d'Athenes). The local Greeks called the dukes "Megas Kyris" (Greek: Μέγας Κύρης, "Great Lord"), from which the shortened form "Megaskyr", often used even by the Franks to refer to the Duke of Athens, is derived.
