Late Latin Duchy of Athens (1340s)

Timeline

1. 1340–1343Duchy of Athens · Central GreeceAfter the Battle of Halmyros in 1311 the Catalan Company replaced the de la Roche family as Dukes of Athens, but the duchy retained Latin feudal titles, Catholic dioceses and remnants of Frankish customary law. In the early 1340s the viceregents ruled in the name of the King of Aragon, with Latin nobles and Catalan military colonists governing jointly, forming a unique 'Latin Duchy–Catalan Company' hybrid polity.
2. 1343–1347Piraeus–Aegina · AtticaIn the mid-1340s the Duchy of Athens competed with Venice in Aegean trade and guarded against the remnants of the de la Roche family and the potential threat of the Navarrese Company. Relying on Aragonese suzerain support to maintain independence, its finances and military strength could no longer restore the Frankish hegemony of 1205, and the Latin duchy entered a late phase dependent on external protection.
3. 1348–1350Thessaly–Attica · Central GreeceIn 1348 Serbian Emperor Dušan conquered Thessaly, and the Latin duchy lost many northern fiefs and fortresses, its territory shrinking to the core of Attica and New Patras. Though the duchy still survived before 1350, it had lost its status as hegemon of Frankish Greece; the hallmarks of the Latin duchy's late period—territorial fragmentation, reliance on mercenaries, nominally Latin but actually Catalan—were by now fixed.
