The Duchy of Neopatras ( ca, Ducat de Neopàtria; scn, Ducatu di Neopatria; gr, Δουκάτο Νέων Πατρών; la, Ducatus Neopatriae) was a principality in southern Thessaly, established in 1319. Officially part of the Kingdom of Sicily, itself part of the Crown of Aragon, the duchy was governed in conjunction with the neighbouring Duchy of Athens, it enjoyed a large degree of self-government. From the mid-14th century, the duchies entered a period of decline: most of the Thessalian possessions were lost to the Serbian Empire, internal dissensions arose, along with the menace of Anatolian beyliks, Turkish piracy in the Aegean and the onset of Ottoman Empire, Ottoman expansion in the Balkans. Enfeebled, the Catalan possessions were taken over by the Florentine adventurer Nerio I Acciaioli in 1385–1390. The title of Duke of Neopatras was held by the heir of the List of Sicilian monarchs, King of Sicily.

History

When the Greek ruler of Thessaly, John II Doukas, died in 1318 without an heir, his domains fell into chaos. The Almogavars of the Catalan Company, who had Battle of Halmyros, recently conquered most of the Duchy of Athens to the south of Thessaly, took advantage of the situation to push north. Led by Alfonso Fadrique, the Catalans took Neopatras in 1319, and by 1325 had also conquered Zetounion, Loidoriki, Siderokastron and Vitrinitsa, as well as—apparently briefly—Domokos, Gardiki, Phthiotis, Gardiki and Pharsalus. The central and northern part of Thessaly remained in Greek hands under a series of local magnates, some of whom recognized Byzantine suzerainty, like Stephen Gabrielopoulos of Trikala; others, however, like the Maliasenos family around Volos, turned to the Catalans for support. The Greek rulers of Thessaly had long, but erroneously, been known as "Dukes of Neopatras" in Western European sources from their capital, modern Ypati; this was a result of confusion from the family name of Doukas, which Western sources mistook as the title of "duke".The actual title borne by the rulers of Thessaly was that of ''sebastokrator''. Properly speaking this was not hereditary, but had to be conferred by the reigning Byzantine emperor. As a result, the territory conquered by the Catalans in Thessaly was organized as the "Duchy of Neopatras" and was divided into five Captaincy, captaincies. The Catalans selected the infant Manfred, Duke of Athens, Manfred, son of King Frederick III of Sicily, as their duke, but actual power was wielded by the Duke's local representative, the vicar-general, as well as by the marshal (''mariscalus exercitus ducatuum'') as the elected head of the Company members. Most of the Duchy's possessions in Thessaly were lost when the region was conquered by the Serbian Empire, Serbs of Stefan Dushan in 1348, but Neopatras and the region around it remained in Catalan hands. In 1377, the title of Duke of Athens and Neopatras was assumed by Peter IV of Aragon. It was preserved among the subsidiary titles of his successors, and was regularly included in the List of titles and honours of the Spanish Crown, full title of the List of Spanish monarchs, Spanish monarchs at least until the War of the Spanish Succession, takeover of the Spanish crown by the House of Bourbon. In 1378–79, the Aragonese lost most of their possessions in Boeotia to the Navarrese Company, while from the south the ambitious Florentine adventurer Nerio I Acciaioli, Nerio Acciaioli, lord of Ancient Corinth, Corinth, took over Megara in 1374 and began applying pressure on Athens. By 1380, the Catalans were left only with the two capitals of Athens and Neopatras, as well as the County of Salona. Athens fell to Acciaioli in 1388, and in 1390 he captured Neopatras as well. Acciaioli could boast in the title "Lord of Corinth and of the Duchy of Athens and Neopatras", but his triumph was short-lived: in 1393/4 the Ottoman Turks conquered Neopatras and the entire Spercheios River valley. Ecclesiastically, Neopatras largely corresponded to the Latin Archbishopric of Neopatras (''L'Arquebisbat de la pàtria''), which had one suffragan: Zetounion (Lamia). Among the Catalan archbishops was Ferrer d'Abella, who tried to have himself transferred to a west European episcopal see, see.
