The Pax Romana Podcast

In 325 AD, a gathering of bishops in a small town near Constantinople changed the course of Christianity and the Roman Empire forever. Known as the Council of Nicaea, this wasn’t just a theological debate—it was a collision of imperial power and religious authority. At its heart was Constantine the Great, the first Christian emperor, whose dream of a unified empire under one God reshaped church and state. But why did Constantine step into this religious fray? How did his decisions at Nicaea influence the future of Western civilization?

Was Constantine's conversion to Christianity genuine? How did it reshape Roman politics and culture? Evidence from Lactantius and Eusebius suggests a sincere conversion, with a divine vision sparking his faith, though political pragmatism shaped its expression. His actions, like the Edict of Milan and church-building, wove Christianity into Roman identity, transforming the empire. Constantine’s legacy established Christianity as Rome’s cornerstone, hinting at a complex blend of faith and strategy that redefined Western history. ⁠⁠Donate: https://www.paypal.com/ncp/payment/WZTWCMWCJJYFC⁠⁠⁠⁠⁠⁠ ⁠⁠⁠⁠⁠⁠YouTube Channel: https://www.youtube.com/@ProfCPE⁠⁠⁠⁠⁠⁠ Buy Professor Elliott's newest book:⁠⁠⁠⁠⁠⁠⁠Pox Romana: The Plague that Shook the Roman World⁠⁠⁠⁠⁠⁠⁠.

The Third Century Crisis prompted Diocletian’s Tetrarchy in 293 AD--a bold four-ruler system to restore order. Then, in 303, Diocletian inaugurated the Great Persecution of Christians. Religion and politics intersected when Diocletian abdicated in 305, setting in motion a chain of events which prompted a succession crisis and empowered a new usurper, Constantine, to make a play for Rome. How did Constantine come to power and how did his rise intersect with the fall of the tetrarchy and sweeping religious changes in the Roman Empire? ⁠⁠Donate: https://www.paypal.com/ncp/payment/WZTWCMWCJJYFC⁠⁠⁠⁠⁠ ⁠⁠⁠⁠⁠YouTube Channel: https://www.youtube.com/@ProfCPE⁠⁠⁠⁠⁠ Buy Professor Elliott's newest book:⁠⁠⁠⁠⁠⁠Pox Romana: The Plague that Shook the Roman World⁠⁠⁠⁠⁠⁠.

What happens when a society’s protectors turn on its elites? Why did the Roman military, with its fierce loyalty and unity, eclipse the wealthy senators of the Pax Romana? How did Rome’s own soldiers, alienated and rootless, turn into “barbarians” within? Peter Turchin's insights offer some useful food for thought. ⁠⁠Donate: https://www.paypal.com/ncp/payment/WZTWCMWCJJYFC⁠⁠⁠⁠ ⁠⁠⁠⁠YouTube Channel: https://www.youtube.com/@ProfCPE⁠⁠⁠⁠ Buy Professor Elliott's newest book:⁠⁠⁠⁠⁠Pox Romana: The Plague that Shook the Roman World⁠⁠⁠⁠⁠.

Was Diocletian’s Edict on Maximum Prices was a bold attempt to combat hyperinflation. It was sold with moralizing rhetoric--not unlike rhetoric in favor of anti-price-gouging laws or wage and price controls in modern states. Diocletian blamed greed instead of addressing currency issues. Did the Price Edict work? ⁠Donate: https://www.paypal.com/ncp/payment/WZTWCMWCJJYFC⁠⁠⁠ ⁠⁠⁠YouTube Channel: https://www.youtube.com/@ProfCPE⁠⁠⁠ Buy Professor Elliott's newest book:⁠⁠⁠⁠Pox Romana: The Plague that Shook the Roman World⁠⁠⁠⁠.

The Roman Empire under Diocletian saw sweeping changes that reshaped its core. Provinces were reorganized and multiplied to tighten administrative control. The bureaucracy swelled, with tens of thousands of officials managing the sprawling empire. Peasants were bound to the land they worked, securing a steady flow of taxes and labor. Meanwhile, the military's reach deepened, its influence seeping into daily life. ⁠Donate: https://www.paypal.com/ncp/payment/WZTWCMWCJJYFC⁠⁠ ⁠⁠YouTube Channel: https://www.youtube.com/@ProfCPE⁠⁠ Buy Professor Elliott's newest book:⁠⁠⁠Pox Romana: The Plague that Shook the Roman World⁠⁠⁠.

Diocletian a low-born Illyrian, rose to emperor in a period of crisis. Instead of waiting for another civil war to erupt, he appointed Maximian to co-rule with him, and handle the problematic western empire. But as problems with invading armies and usurpers continued, Diocletian took the dramatic step of appointing additional emperors in AD 293, establishing the Tetrarchy ('Rule of Four Men'). This militarized system concentrated power in the hands of four absolute autocrats, sidelining the Senate and marking the shift from Principate to Dominate.

Turmoil resumed following Emperor Aurelian’s assassination in AD 275. Rapidly changing emperors, barbarian invasions and internal strife defined the years 275-284. Within this chaos, Diocles, a low-born Dalmatian soldier, seized power in 284. But instead of joining the long list of warlords that only temporarily won power before falling in civil war, he laid a new foundation for a transformative era in Roman politics.

Students often ask me for Roman Empire book recommendations. Listeners have as well. It is easy to find popular histories, but here I discuss eleven excellent hidden gems--books that are great for the causal reader, but robust enough that I’ve used them in my research and teaching. These aren’t popular titles, but they’re brilliantly crafted by leading academics, diving deep into Rome’s history, culture, religion and economy. Each book is well-written, accessible, and budget-friendly, perfect for history fans and students eager to explore Rome’s epic story.

Lucius Annaeus Seneca, the 1st-century Roman Stoic, sparks endless debate. His works, like Letters to Lucilius and On the Shortness of Life, preach virtue, simplicity, and resilience. Yet, Seneca amassed a fortune of 300 million sesterces, owned lavish villas and advised Nero. Critics call him a hypocrite. His Stoic writings inspire, but do they align with his actions? This tension defines his legacy. Was Seneca a true Stoic, or was he a fraud?

Listeners and students have asked me who my favorite Roman emperor is. Lists of the "best" emperors often highlight giants like Augustus, Trajan, and Marcus Aurelius—undeniably impressive for their conquests and governance. But my favorite, for personal reasons, is a man overlooked by many historians and dismissed by the writers of his time. A blue-blooded elite, he seized power in a chaotic coup, faced senatorial scorn, yet ruled effectively. He expanded the empire, improved infrastructure, and, remarkably, seemed to enjoy himself while doing it. Who is this underappreciated emperor? Check out the episode to find out.

Ancient Rome--the heart of an empire--was fed by a vast network of ships and storehouses that brought grain from distant lands like Egypt and Africa. The Roman state orchestrated this colossal effort, called the Annona, to feed its citizens, a feat unmatched in the pre-industrial world. But behind this marvel lay a darker story—rural farmers stripped of their harvests, urban masses dependent on handouts and a system driven by political ambition. Today, we’ll explore this complex machine that kept Rome alive and ask: was the Roman government’s grain dole system helpful or harmful?

In first-century Galilee, King Herod Antipas’s stable rule provided a relatively peaceful setting for Jesus of Nazareth, born around 4 BC, to emerge as a Jewish preacher, promoting repentance and the kingdom of God. Conversely, Judea faced turmoil under Roman prefects like Pontius Pilate. By around AD 30, Jesus entered Jerusalem, and was crucified within a week. But was Jesus a mere mythological figure, or did he really exist? Ancient sources outside the New testament canon in fact confirm that Jesus was real. Josephus’s Antiquities (AD 93–94) describes Jesus as a wise man crucified under Pilate; Tacitus’s Annals (AD 116) notes “Christus” suffered 'the extreme penalty'; Pliny the Younger’s letters (AD 112) affirm a growing movement of Christ-followers almost a century after Jesus' crucifixion.

Roman emperors governed a sprawling empire, from Britain to Syria—but how did they maintain control over such vast lands? Did they rely on spies to monitor their enemies and ensure loyalty? Enter the frumentarii, a mysterious group of soldiers originally tasked with grain supply. History reveals they evolved into agents of espionage, assassination, and taxation, serving emperors like Hadrian and Severus. This episode uncovers their shadowy roles—and why their power crumbled under Diocletian.

Did Romans trust their money? Roman officials required legal exchange rates, but not everyone obeyed them--especially when mints adulterated or debased precious metal coinage. Only scant evidence of rebellion survives, but there are hints that show Romans inventing new conventions--some quite elegant. How overt was monetary defiance? Marcus Cornelius Fronto, famed rhetorician and tutor to Emperor Marcus Aurelius, once told the emperor in a letter: “Cleave to the old coinage”. Romans trusted coins when they were reliable, but were skeptical of newly debased coin .

On March 15, 44 BC, Julius Caesar, appointed dictator for life, was assassinated by senators led by Marcus Brutus and Gaius Cassius. Caesar’s dictatorship, his military conquests, populist reforms and unprecedented power seemed like the style of monarchy the Republic was meant to guard against. The conspirators against Caesar justified the killing as a constitutional defense against tyranny. Yet, their motives were questionable, and the outcome of the assassinate simply led to more tyranny. So was the assassination of Julius Caesar justified?

In 58 BC, Julius Caesar embarked on a campaign that transformed Gaul—modern France, Belgium, and beyond—into a Roman province . What propelled this conquest? Strategic fears had long haunted Rome, from the Gallic sack of the 390s BC to Germanic pressures across the Rhine. Economic prospects tantalized as well. Yet Caesar’s ambition loomed largest, and his victories reshaped what had been a frontier into the Roman Empire’s heartland.

Rome’s early Republic leaned on its legions, with no real navy to speak of—until Carthage, a sea-dominating empire, sparked the First Punic War in 264 BC. Exposed and outmatched, Rome turned the tide in 261 BC, reverse-engineering a captured Carthaginian ship to craft a fleet of quinqueremes. Armed with ingenious corvus boarding bridges, Rome's new navy stunned Carthage, and launched Rome as a Mediterranean powerhouse. How did land-locked Rome master the seas?

Aurelian—a gritty Balkan soldier—seized a crumbling Roman Empire in AD 270. His five-year reign still stuns: how did he crush Germanic hordes, topple Zenobia’s Palmyrene Empire and reunite the Gallic Empire under Roman rule? But Aurelian was more than a conqueror. He constructed miles of walls around Rome, and erected a massive temple to Sol Invictus--god of the unconquered sun.

As a lethal plague tore through Rome, Persian king Sapor I struck the Empire’s east, capturing Emperor Valerian—a staunch senator and fierce Christian persecutor—after his bold counterattack failed. Internal strife and external foes shattered Rome into three warring realms: the Gallic and Palmyrene Empires rose amidst the chaos. Would the third century witness Rome’s doom?
