Foundation and dynasties

A Frankish state covering Attica and Boeotia (capitals Thebes and Athens), founded 1205 under the Burgundian knight Otto de la Roche (called "Duke" from 1205, the title becoming official 1260). Three periods: de la Roche (French, 1205–1311), Catalan (1311–1388), and Acciaioli (Florentine, 1388–1458).

Halmyros and the Catalans

In 1308 the duchy passed to Walter V of Brienne, who hired the mercenary Catalan Company against Thessaly, then tried to cheat them of pay. At the Battle of Halmyros (15 March 1311) — earlier called the Battle of the Cephissus/Orchomenos — the Catalans annihilated Walter and the flower of Frankish chivalry, seizing the duchy. Catalan rule (under the Crown of Aragon/Kings of Sicily, using the Assizes of Romania) lasted until 1388.

Acciaioli and fall

The Florentine Acciaioli family (Nerio I from 1388) took Athens; after a brief Venetian interlude (1395–1402), the Acciaioli ruled until the Ottoman conquest. The last duke, Francesco II Acciaioli, was deposed when Ottoman forces under Turahanoğlu Ömer Bey took Athens; the standard dates are the Ottoman conquest of Athens in 1456 and of the duchy's remnants (the Acropolis) by 1458.
