Emperor (tsar) Ivan Alexander of Bulgaria, who had married a certain despotēs Constantine. Konstantin married as his second wife Eudokia of Trebizond, daughter of Emperor Alexios III of Trebizond and Theodora Kantakouzene. By his first wife, Konstantin had at least one daughter and possibly a son: Helena Dragases (Jelena Dragaš, nun Hypomone), who married the Byzantine Emperor Manuel II Palaiologos and died on 13 May 1450. Their many children included the last two Byzantine emperors, of whom Constantine XI added the name Dragaš (in Greek, Dragasēs) to his own. Constantine XI was named after his grandfather. Legacy Dejanović is venerated in Serb epic poetry as Beg Kostadin (in poetry he was given a title of beg because he became an Ottoman vassal). Usually depicted as an overraly negative character, his characterisation primarily serves as a contrast to the persona of Marko Kraljević (the two are often portrayed as being blood brothers), with a purpouse of emphasising the difference between the two seemingly identical natures of their respective relations with the Ottomans, since both were latter's vassals. Their motives are, however, somewhat different. Whereas Marko is portrayed as accepting the Ottoman suzeranity for the sake and the well-being of his flock, Konstantin seeks a way to preserve his position and privileges with little to no regard to any form of higher moral code.
