Юстиниан II
Tiberius (, "Tiberios"; 705–711), sometimes enumerated as Tiberius IV, was the son of Emperor Justinian II and Theodora of Khazaria. He served as co-emperor of the Byzantine Empire with his father Justinian II, from 706–711. Both were killed in 711, when Bardanes led a rebellion which marched on Constantinople. After Tiberius' death, two different individuals impersonated him, with one, named Bashir, going on to be hosted by Hisham ibn Abd al-Malik, the Umayyad caliph, before his lie was discovered and he was crucified.
