Augustus
Augustus (; 23 September 63 BC – 19 August AD 14) was a Roman statesman and military leader who was the first Emperor of the Roman Empire, controlling Imperial Rome from 27 BC until his death in AD 14. His status as the founder of the Roman Principate has consolidated an enduring legacy as one of the most effective and controversial leaders in human history.
Mark Antony
When Antony died, Octavian became uncontested ruler of Rome. In the following years, Octavian, who was known as Augustus after 27 BC, managed to accumulate in his person all administrative, political, and military offices. When Augustus died in AD 14, his political powers passed to his adopted son Tiberius; the Roman Principate had begun.
