Leo the V the Armenian was emperor of the Byzantine Empire from 813 to 820 CE. He was of Armenian descent and the last ruler of the Isaurian dynasty which had been founded by Leo III (r. 717-741 CE). The emperor's reign, after early military successes against the Bulgars, is chiefly remembered for beginning the second wave of iconoclasm in the Byzantine Church, that is the destruction of religious icons and treating those who worshipped them as heretics.
