What Is 187 CE

Overview

187 CE is a year in the Common Era that falls within the late Roman Imperial period. While not marked by a single world-changing event, it was part of a pivotal era in European and Mediterranean history. This year occurred during the reign of Emperor Commodus, who ruled the Roman Empire from 180 to 192 CE after the death of his father, Marcus Aurelius.

The Roman Empire in 187 CE was experiencing both internal instability and external military pressures. Though it maintained vast territories across Europe, North Africa, and the Middle East, signs of decline were emerging. Economic strain, military overextension, and leadership challenges would soon contribute to the Crisis of the Third Century.

• Commodus was the sole ruler of the Roman Empire in 187 CE, having assumed power in 180 CE after his father’s death, marking a shift from philosopher-kings to erratic leadership.
• The Roman Empire spanned approximately 5 million square kilometers in 187 CE, making it one of the largest political entities in ancient history.
• The capital of the Roman Empire remained Rome, though the administrative center increasingly shifted toward Nicomedia and other eastern cities in later decades.
• The population of the Roman Empire in 187 CE is estimated at 55–60 million people, with Rome city itself housing over 1 million residents.
• The Antonine Plague, likely smallpox, which began in 165 CE, may have still been affecting military recruitment and urban populations in 187 CE, weakening imperial resilience.

How It Works

Understanding the significance of 187 CE requires examining the political, military, and cultural structures of the Roman Empire at the time. This year did not witness a major battle or decree, but it reflects broader trends in imperial governance and societal change.

• Commodus' Rule:Commodus increasingly viewed himself as a divine figure, renaming Rome 'Colonia Lucia Annia Commodiana' in 185 CE and identifying as Hercules reborn, undermining imperial dignity.
• Military Structure: The Roman legions in 187 CE numbered around 375,000 soldiers, deployed across frontiers from Britain to Syria to protect the empire’s vast borders.
• Economic System: The denarius, Rome’s silver coin, had been steadily devalued; by 187 CE, its silver content had dropped to less than 50% of its original weight.
• Provincial Administration: The empire was divided into about 45 provinces in 187 CE, each governed by appointed officials who reported to the emperor in Rome.
• Religious Landscape: Traditional Roman religion coexisted with mystery cults and early Christianity, which had fewer than 50,000 adherents in the empire by 187 CE.
• Urban Infrastructure: Roman cities in 187 CE featured advanced engineering, including aqueducts supplying over 1 million liters of water daily to cities like Rome and Carthage.

Key Comparison

This comparison highlights how 187 CE placed the Roman and Han empires as the two dominant superpowers of the ancient world. Both ruled over 50 million people and maintained vast infrastructures, though they operated independently on opposite sides of Eurasia.

Key Facts

187 CE is a snapshot of a turning point in Roman history, where stability began to erode under personal rule and military challenges. These facts illustrate the empire’s condition during this period.

• Commodus celebrated a triumph in 187 CE for victories in Germania, though these were likely exaggerated to bolster his image after years of frontier warfare.
• The Legio II Parthica was established later by Septimius Severus, but in 187 CE, Legio X Gemina was stationed in Hispania, maintaining regional stability.
• Rome’s annona system distributed free grain to about 200,000 citizens in 187 CE, a key tool for maintaining urban loyalty.
• The Saturnalia festival was widely celebrated in December 187 CE, reflecting the continued importance of Roman religious traditions.
• Christian theologian Irenaeus of Lyon was active around 187 CE, writing Against Heresies to unify Christian doctrine amid growing diversity.
• The Limes frontier system in Germania was under constant pressure, with raids recorded as early as 180 CE, continuing into 187 CE.

Why It Matters

While 187 CE may not be remembered for a specific event, it represents a critical juncture in the trajectory of the Roman Empire. The choices made during Commodus’ reign had long-term consequences for imperial stability and governance.

• The decline in imperial legitimacy under Commodus contributed to the Year of the Five Emperors in 193 CE, just a few years after 187.
• Military spending in 187 CE consumed an estimated 60–70% of the imperial budget, straining the economy and leading to tax increases.
• The erosion of senatorial influence in 187 CE marked a shift toward autocratic rule, weakening Rome’s political institutions.
• Urban centers in 187 CE faced growing inequality, with a small elite controlling over 70% of land and wealth.
• The cultural legacy of 187 CE includes literature, engineering, and law that influenced Europe for centuries after the empire’s fall.

Studying years like 187 CE helps historians understand the slow, systemic changes that precede major collapses. It reminds us that history is shaped not only by dramatic events but also by the quiet accumulation of trends over time.
