Philippkios Bardanes (d. 714) was briefly the emperor of the Byzantine Empire, reigning from 711 to 713. He incited the rebellion that overthrew Justinian II for the final time. His short reign saw his support for the doctrine of monothelitism. He was declared a heretic. Further, his redeployment of troops into the Balkans gave the Umayyad Caliphate a chance to make military gains in 712. In 713, Bardanes was blinded in his bath and sent into exile, where he died in 714.
Bardanes, who preferred to go by his Greek name Philippikos, was a soldier from Armenia in the late 600s to early 700s CE. During the first part of the reign of Justinian II, he saved the young emperor from attack by a Sklavinian hiding underwater. Justinian never forgot this act of loyalty and sent Bardanes on various missions, much to the disapproval of Myakes, Justinian's chief of excubitors. Bardanes ultimately turned against Justinian, preventing the massacre of children in Kherson, the news of which greatly displeased Justinian.
