This tradition is, however, evidently an invention meant to glorify the family, at the time the Empire's ruling dynasty, by 11th-century court chroniclers..

It is unclear whether the ''doux'' in Andronikos's name is a surname or a military rank; some scholars consider them as belonging to the Doukas clan, although the exact relation, if any, with the earlier Doukai is impossible to ascertain.

Under the Komnenoi

Their association with the Komnenoi helped ensure the continued prominence and prestige of the Doukas name at the apex of the Byzantine aristocracy into the
Komnenian period The Byzantine Empire was ruled by emperors of the Komnenos dynasty for a period of 104 years, from 1081 to about 1185. The ''Komnenian'' (also spelled ''Comnenian'') period comprises the reigns of five emperors, Alexios I Komnenos, Alexios I, Jo ...

ly) linked to the actual Doukai, who became relatively obscure after the turn of the century. It is hence impossible to clearly distinguish the numerous holders of the name or to discern their exact relationship with the 11th-century Doukid dynasty. The actual bloodline of Constantine X died out probably before 1100, and the last known descendants of his brother, the ''Caesar'' John, lived in the first half of the 12th century. The majority of the 12th-century bearers of the name were therefore most likely members of other families, linked through marriage with the Doukai, who chose to emphasize this relationship due to the prestige the name conferred..


Later branches

In this way, mingled with other noble families or adopted ''de novo'' even by humble families unrelated to the original lineage, the Doukas name survived into the last centuries of the Byzantine Empire. A prominent example of the Late Byzantine period were the Komnenodoukai of the
Despotate of Epirus The Despotate of Epirus ( gkm, Δεσποτᾶτον τῆς Ἠπείρου) was one of the Greek successor states of the Byzantine Empire established in the aftermath of the Fourth Crusade in 1204 by a branch of the Angelos dynasty. It claim ...
