At 19, Gaius Octavius learned that his assassinated great-uncle Julius Caesar had left him three quarters of his estate and his famous name, along with a target on his back. This episode examines how an obscure young man from an equestrian family accepted that dangerous inheritance, seized Caesar’s war chest without legal authority, paid veterans to form a private army, and outmaneuvered Mark Antony before defeating Antony and Cleopatra at Actium in 31 BC.

We unpack the Principate, the carefully staged illusion of a restored republic, from the title Augustus in 27 BC to the second settlement of 23 BC, when he gave up the consulship but kept supreme military authority. We also explore the disaster in the Teutoburg Forest, the forced marriages and family tragedies behind his succession planning, his creation of Rome’s fire and police services, the Res Gestae, and how historians from Ronald Syme to Adrian Goldsworthy have judged him.
