Katakalon Tarchaneiotes

Katakalon Tarchaneiotes (Greek: Κατακαλών Ταρχανειώτης), mentioned in the works of Nikephoros Bryennios the Younger as Katakalon Katakalos (Κατακαλών Κατακαλός), was an 11th-century Byzantine official, active during the reigns of Michael VII Doukas (r. 1071–1078), Nikephoros III Botaneiates (r. 1078–1081) and Alexios I Komnenos (r. 1081–1118).

He first appeared in 1074, when he replaced his father as Duke (dux) of Antioch and confronted the revolt of Philaretos Brachamios, though without success. Years later, as Katepano of Adrianople (now Edirne), he initially confronted the revolt of Nikephoros Bryennios the Elder but ended up allying with him and taking part in the Battle of Kalavrye. In 1094, he attended the Council of Blachernae (1094), and in 1095, defended Adrianople during a Cuman invasion.
