The Roman Empire had been born. Once Octavian named Tiberius as his heir, it was clear to everyone that even the hope of a restored Republic was dead. Most likely, by the time Augustus died, no one was old enough to know a time before an Emperor ruled Rome. The Roman Republic had been changed into a despotic régime, which, underneath a competent and strong Emperor, could achieve military supremacy, economic prosperity, and a genuine peace, but under a weak or incompetent one saw its glory tarnished by cruelty, military defeats, revolts, and civil war.
