Septimius Severus is now ruler or Rome without opposition, had been all things, and all was of little value. He is now distracted with the care, not of acquiring, but of preserving an empire.

Septimius Severus is proclaimed the new Emperor of Rome, but doesn’t have time to rest on his laurels. With rivals to the east and west, not to mention the problematic Parthians, he has an empire to consolidate.

The Roman Empire shudders in the wake of Commodus’ death, which if you recall, was a matter of months but a whole two emperors ago. Striding into Rome at the head of an army is Septimius Severus, ready to set the right path and found a new, powerful dynasty. Year of the five emperors, take three.

Enraged at the lack of a decent bonus, the Praetorian Guard cut down the newly installed Emperor Pertinax and resolve to sell the throne to the highest bidder. Stepping forward with a sufficient bank balance is Didius Julianus, a man with a proven track record in both the military and the senate. What could go wrong? Year of the five emperors, take two.

Guest: Dr Caillan Davenport (Roman History, Macquarie University).

Many saw Pertinax as a safe pair of hands to hold the empire - an old general and close advisor of Antoninus Pius, he represented a regime change from the days of lavish excess of Commodus. But was it too much too soon? Well they don't call 193CE the year of the five emperors for nothing.

Livy was an historian writing during the Augustan age of Rome, who wrote one of the empire’s most famous works – an extensive and exhaustive history, spanning 142 books. Of those we have the first quarter, and they’ve influenced every work on Rome that has been written since.

Guest: Professor Ronald Ridley (Honorary,Historical and Philosophical studies, University of Melbourne).

For much of our journey through the Antonine dynasty we’ve had Dio Cassius as our guide. As both a historian and a senator, Dio had a ringside seat to some of the greatest Emperors the Roman empire had seen. He wrote an extensive and what is considered reliable history of the Roman empire, spanning 80 volumes, many of which we have today.

Epicureanism was an ancient philosophy founded in Athens which became popular throughout the Roman world. It teaches that the greatest good is to seek modest pleasures, and this will lead to a state of tranquility.

The borders of the Roman Empire grew and shrank throughout its history, reaching its greatest extent during the rule of Trajan. How the Romans viewed and managed their provinces changed with the politics of Rome, and their relationship with outside powers influenced what it meant to be a Roman.

Guest: Dr Paul Burton (Senior Lecturer, Centre for Classical Studies, Australian National University).

One thing you can say about the reign of Commodus is that it must have been an interesting time to live in Rome. Between the spectacles in the colosseum and the lowered life expectancy in the Senate, it was just a matter of time until someone took a knife to Commodus, and after almost a century in power, the Antonine dynasty comes to an end.
