What Is 193 CE

Overview

193 CE stands as one of the most turbulent years in Roman imperial history, marked by political chaos, military insurrection, and rapid changes in leadership. Known historically as the Year of the Five Emperors, it followed the assassination of Emperor Commodus and ushered in a period of civil war and instability across the empire.

This year exemplified the fragility of imperial succession in Rome, where power increasingly depended on military support rather than dynastic legitimacy. The events of 193 CE ultimately led to the rise of Septimius Severus, a general who restructured the empire’s power dynamics and established a new imperial dynasty.

• Pertinax became emperor in January 193 after the murder of Commodus but was assassinated by the Praetorian Guard after only 87 days in power due to his strict reforms.
• Didius Julianus notoriously purchased the throne from the Praetorian Guard for 25,000 sesterces per soldier, making his reign one of the most scandalous in Roman history.
• Pescennius Niger, governor of Syria, declared himself emperor and gained support from the eastern provinces, controlling key territories including Antioch and Egypt.
• Clodius Albinus, governor of Roman Britain, was initially named co-Caeser by Septimius Severus but later declared himself Augustus, challenging Severus’ authority.
• Septimius Severus, commander of the Pannonian legions, marched on Rome, declared himself emperor, and ultimately defeated all rivals to establish the Severan dynasty in 197 CE.

How It Works

The collapse of stable succession in 193 CE revealed how Roman imperial authority had become dependent on military backing rather than legal or senatorial approval. Each claimant to the throne leveraged regional armies and provincial loyalty to advance their cause.

• Assassination of Commodus: On December 31, 192 CE, Emperor Commodus was strangled by a wrestler named Narcissus, ending the Antonine dynasty and triggering a power vacuum.
• Praetorian Auction: After killing Pertinax, the Praetorian Guard infamously auctioned the throne, with Didius Julianus winning by promising 25,000 sesterces per guard.
• Military Revolt: Septimius Severus, stationed in Illyricum, responded to Pertinax’s death by marching on Rome, declaring himself avenger of the murdered emperor.
• Civil War: From 193 to 197 CE, Rome was engulfed in civil war as Severus defeated rivals including Niger at the Battle of Issus in 194 CE and Albinus at Lugdunum in 197 CE.
• Eastern Support: Pescennius Niger gained backing from Parthia and several eastern legions, but his failure to secure naval dominance weakened his campaign.
• Severan Reforms: After victory, Septimius Severus doubled soldiers’ pay to 500 denarii annually and purged the Senate, consolidating power in the military.

Comparison at a Glance

Below is a comparison of the five claimants to the Roman throne in 193 CE, highlighting their backgrounds, support bases, and outcomes.

This table illustrates how military strength, rather than political legitimacy, determined success in 193 CE. While Julianus had the Senate’s initial recognition, Severus’ control of disciplined legions proved decisive. The year underscored the decline of senatorial influence and the rise of the army as the true arbiter of imperial power.

Why It Matters

The events of 193 CE reshaped the trajectory of the Roman Empire, marking a turning point in how emperors were chosen and how power was maintained. It exposed the vulnerabilities of centralized rule without clear succession mechanisms and elevated the military as the dominant political force.

• The Year of the Five Emperors demonstrated that imperial authority could be bought, sold, and seized by force, undermining traditional Roman governance.
• Septimius Severus’ rise marked the beginning of the Severan dynasty, which ruled until 235 CE and included emperors like Caracalla and Elagabalus.
• The Praetorian Guard’s role in selling the throne led to its eventual disbandment by Severus, who replaced it with a loyal legionary guard.
• Military loyalty became the primary criterion for power, leading to increased provincial recruitment and army politicization.
• The civil wars of 193–197 CE weakened frontier defenses, contributing to later invasions during the Crisis of the Third Century.
• This period influenced later historians like Cassius Dio, who documented the chaos and criticized the erosion of senatorial authority.

The legacy of 193 CE endures as a cautionary tale about the fragility of power and the dangers of militarized politics in any empire.
