He served as co-emperor of the Byzantine Empire with his father Justinian II, from 706–711. In 705, Justinian II, who had previously been emperor of the Byzantine Empire from 685–695, but had been usurped by Leontios, used a vast army of Khazars, Bulgars, and Slavs to retake the throne from Tiberios III, who had in turn overthrown Leontios.[2] While Justinian led troops into the Byzantine Empire, he left his wife, Theodora of Khazaria, behind in Bulgaria. This news frightened the Byzantines, especially Emperor Leo III.
