The Emperor was widely regarded as the savior of Rome. The son of slaves he had fought his way to power against the enemies of Rome. After a half century of chaos he brought order and unity to Rome, crushing pretenders to the imperial purple and restoring the borders of the Empire against the barbarian tribes. Under his tetrarchy system Rome would be ruled by two Emperors and two Caesars who would eventually succeed the Emperors. Peace now reigned in the Empire after decades of strife. Small wonder that Gaius Aurelius Valerius Diocletianus, better known to history as Diocletian, was hailed as a second Romulus, a second founder of Rome.
