Constantine Komnenos Doukas

Constantine Komnenos Doukas (Greek: Κωνσταντίνος Κομνηνός Δούκας; ca. 1172 – after 1242), usually named simply Constantine Doukas, was a son of the sebastokrator John Doukas and brother of the founders of the Despotate of Epirus, Michael and Theodore. He was named governor of Acarnania and Aetolia and given the rank of Despot, which he held until his death.

Little is known about his life. He was born ca. 1172, the youngest son of John Doukas by his second wife Zoe Doukaina. He may be identical to the Constantine Doukas who on 12 April 1204, on the eve of Constantinople's fall to the Fourth Crusade, competed with Constantine Laskaris for the imperial crown. Around 1208, he accompanied the deposed emperor Alexios III Angelos, who had sought refuge in the Epirote court, to the Sultanate of Rum. From there, with Turkish support, Alexios unsuccessfully tried to take over the Empire of Nicaea.

Returning to Epirus, Constantine was named governor of Acarnania and Aetolia, with Naupaktos as his capital, probably after Theodore Komnenos Doukas's succession as ruler of Epirus in 1215. In 1216, he accompanied his brother Theodore in a campaign against Bulgaria. Constantine's rule was successful, as he recovered Neopatras and Lamia from their Latin rulers, but was marred by his clash with the bishop of Naupaktos, John Apokaukos, who protested his authoritarian rule and extortionate tax demands from the populace. The dispute led to the forcible deposition and exile of Apokaukos in 1220, and was resolved only in May 1221 after a synod including representatives from most of the senior sees in Greece and the Epirote domains. Indeed, the relations between Constantine and Apokaukos became cordial thereafter, and the bishop even composed an encomium in his honour.
