Manuel Kamytzes Komnenos Doukas Angelos was a Byzantine general who was active in the late 12th century, and led an unsuccessful rebellion in 1201–02, against his cousin, Emperor Alexios III Angelos.

Prōtostratōr was a Byzantine court office, originating as the imperial stable master. Its proximity to the imperial person led to a highly visible role in imperial ceremonies, and served as a springboard for several capable individuals, like Manuel the Armenian or the future emperors Michael II and Basil I the Macedonian, to reach the highest offices. From the mid-11th century, the post rose in importance, becoming more an honorific dignity for senior members of the court, than an actual office. From the 13th century on, the post could be held by several persons, and ranked eighth in the overall hierarchy of the court. Throughout its history, it was a title often borne by senior military commanders. The female form of the title, given to the wives of the prōtostratores, was prōtostratorissa (πρωτοστρατόρισσα).
