Konstantinos Maniakes

Constantine Maniakes (; ) was a senior Byzantine court official of the mid-9th century.

Biography Maniakes was probably descended from a noble Armenian family. He came to the Byzantine court in the reign of Emperor Theophilos (r. 829–842), as a member of a delegation from the Armenian princes, and was left in the Byzantine capital, Constantinople, as a hostage. His intelligence and physical qualities soon marked him out, and he quickly won the confidence of Theophilos and rose in the court hierarchy. By the end of Theophilos's reign, he was droungarios of the Watch. He retained this post after Theophilos's death, and it was he who in 843 enforced the deposition of Patriarch John VII Grammatikos, who later falsely accused Maniakes of torturing him.
