Demitre was an Albanian count in the Catalan dominions in late-14th-century Thessaly, during the Frankokratia.
Mentioned as de Mitre and lo comte Mitra (a corruption of Dimitri/Demetrius[1]) in contemporary sources, he was an Albanian chieftain based in southeastern Thessaly (Albanians had migrated to Thessaly from about 1320).[2] He could rally 1,500 cavalrymen and was entitled to bear the royal banner of Aragon as a born vassal of Peter IV.[3] Among the eighteen Catalan vassals of the area in 1380-1 he ranks second below the Count of Salona and above the Margrave of Bodonitsa.[2] In a document of April 1381, he is listed among those greeted by Peter IV for their services against the Navarrese Company in 1379.[2]
