(). The name or origin of his mother is unknown. In 1192/93, Isaac II named him fleet commander ('' doux tou stolou'') and governor of Philippopolis, an area then suffering from the ongoing Vlach–Bulgarian rebellion. The contemporary historian Niketas Choniates writes favourably of Constantine, noting that he was able to train his troops well and to command loyalty from them, and that although naturally impetuous "in the manner of lion cubs", he was also willing to listen and be restrained by the advice of the more experienced professionals placed under his command. Constantine was able to check the rebels' raids against the region of Philippopolis and Berrhoe, so that the rebels "cowered in fear of him and were more panic-stricken at the sight of him than of the emperor". His success on the battlefield emboldened Constantine, however, and he started aiming to usurp the throne.

Constantine's followers handed him over to the emperor, claiming that they had been pressured into supporting his usurpation against their will. Isaac II harboured his doubts about their sincerity, but chose to overlook their part in the failed uprising. In the end, only Constantine was punished, by being blinded. According to Choniates, this deed greatly encouraged the Bulgarian rebels, who had feared Constantine's ability and much preferred the ineffective Isaac II to remain on the throne, if possible, for ever. Constantine's subsequent fate, or whether he was married and had any offspring, is unknown.
