January 29, 2026

Overview

In this engaging encore episode, host Gary Arndt delves into one of the most catastrophic eras in Roman history—the Crisis of the Third Century (235–284 CE). He explains how the once-mighty Roman Empire almost disintegrated under the pressure of devastating plagues, economic collapse, constant invasions, and relentless political turmoil. With vivid storytelling and sharp insight, Gary narrates the rapid succession (and frequent assassination) of emperors and the series of disasters that battered Rome, showing that only luck and timely leadership kept the empire from total collapse.

Key Discussion Points & Insights

1. Background: Setting the Stage for Crisis

• Macro-level Problems (02:00–03:15)
  • Aftereffects of the Antonine Plague: Severely weakened the population and military; economy suffered.
  • Plague of Cyprian (249–262): Cities like Alexandria lost up to 60% of their population.
  • Runaway Inflation:
    • Denarius coin’s silver content dropped from 98% (Augustus) to 50% at start of crisis, plummeting further.
    • Gold Aureus debased from 95% to 38% gold.
    • Debasement led to severe price increases and economic chaos.
  • End of Roman Climate Optimum:
    • Shifts in climate led to inconsistent agricultural productivity.
  • Lack of Succession Plan:
    • With no established system for imperial succession, each emperor’s death or assassination created power vacuums and chaos.

“There was never a system of succession which was put in place. Every time one emperor replaced another, things were kind of up in the air.” (04:00, Gary Arndt)

2. Explosive Political Turmoil: Emperor Turnover

• Beginning of the Crisis (04:25)
  • Assassination of Alexander Severus (235 CE): Last period of stability ended as his own troops turned on him due to his negotiation attempts with Germanic tribes rather than confrontation.
  • Rise of Maximinus Thrax:
    • Considered an outsider, ruled as a despotic military strongman. (05:00)
  • The Year of Six Emperors (238 CE):
    • Revolts, assassinations, and rapid turnovers: Maximinus, Gordian I, Gordian II, Pupienus, Balbinus, and finally young Gordian III, who ruled at 13.

“I think you probably realize by now that the third century was a very bad time to be a Roman emperor.” (09:25, Gary Arndt)

• Rapid Succession and Violent Ends
  • Gordian III murdered at 19 (244).
  • Philip the Arab and son killed in civil war (249).
  • Decius dies in battle against the Goths (251)—first emperor to die in combat vs. a foreign army.
  • Hostilian taken by plague.
  • Trebonianus Gallus, Aemilian, Valerian—all murdered or captured.

3. Fragmentation of the Empire

• Valerian and Gallienus (12:30)

  • Valerian splits empire between himself (East) and his son (West) due to overwhelming pressures.
  • Catastrophe Strikes:
    • Valerian is captured alive by Persian King Shapur I (a humiliation for Rome), dies in captivity under grim rumors.
  • Breakaway States Emerge:
    • Gallic Empire in the West (Gaul, Britannia, Hispania) under Postumus.
    • Palmyrene Empire in the East under Queen Zenobia (Syria, Egypt).

• Chaos and Foreign Invasions

  • Goths sack the Balkans and Athens.
  • Continuous civil war, provinces seceding, and borders collapsing.

“There were people in the outer fringes of the empire who had no clue who the emperor was for much of this period because the job was being changed so frequently.” (23:35, Gary Arndt)

4. Brief Resurgence: Competent Leadership Emerges

• Aurelian ("Restorer of the World") (16:50)

  • Defeats both breakaway empires, reunifies Rome.
  • Builds the Aurelian Walls around Rome and initiates currency reforms to fight hyperinflation.
  • Assassinated in 275—demonstrating that even competence couldn’t break the cycle of murder.

• Further Instability

  • Rapid-fire emperors: Tacitus, Florianus, Probus, Carus, Numerian, Quirinus—all die violently or mysteriously, except Carus (killed by lightning).
  • Diocletian (284–305): Ends the chaos—rules for 21 years, overhauls government and military, and voluntarily retires to grow cabbages!

“The only reason it didn’t fall apart was really due to luck and the fact that the right emperors came along at just the right time.” (24:20, Gary Arndt)

Notable Quotes & Memorable Moments

• "If everything I just went over in this episode seems really confusing and a giant mess, that's because it was." (23:25, Gary Arndt)
• "In 260, while fighting the Persians, Valerian was not killed in combat or assassinated. Something worse happened. He was captured alive by the Persian king Shapur I … The reason why his capture was worse than death was because it was a huge sign of weakness for Rome." (11:40)
• "Aurelian was the first truly competent emperor in several decades … earning the title Restitutor Orbis, or Restorer of the World." (16:55)
• "Diocletian ruled for 21 years until he voluntarily abdicated so he could retire and grow cabbages, which he did for four years until dying of natural causes, which was a highly unnatural way for a Roman emperor to die during this period." (20:35)
