Isaac Kontostephanos

Isaac Kontostephanos (Greek: Ἰσαάκ Κοντοστέφανος) was a Byzantine admiral during the reign of Emperor Alexios I Komnenos (r. 1081–1118) and who fought in the Byzantine–Norman wars. Much of what is known about Isaac’s military career is from Anna Komnene’s Alexiad where he is depicted as incompetent during the second Norman invasion of the Balkans. However, this image is reflective of Anna’s politics during the time of the composition of her work in the 1140s, specifically the Norman invasion of 1147-49 and internal competition with the Kontostephanoi.
