The Impact of Marcus Aurelius' Eastern Campaign on the Socio-Political Situation of the Roman Empire
Abstract
With Pompey’s incorporation of the Seleucid Kingdom into Rome’s borders in the first century BCE, the Roman Empire became a neighbor of the Parthian Kingdom, and the Euphrates River was established as the natural frontier. Thus began the centuries-long struggle for dominance in the East between Rome and Parthia. Although no war occurred between the Roman Empire and the Parthian Kingdom during the early imperial period, the political tensions that arose over the Kingdom of Armenia during the reigns of Nero and Trajan led to armed conflict. As a result of Emperor Trajan’s eastern campaign, Rome’s borders expanded as far as the Persian Gulf. However, his successor Hadrian abandoned Trajan’s gains and withdrew Roman control to the western bank of the Euphrates. Antoninus Pius likewise followed this more moderate policy. This stance was perceived by the Parthian Kingdom as a sign of weakness, prompting them to seize the Kingdom of Armenia and attempt to occupy Rome’s eastern territories. This attempted occupation at the end of Pius’s reign became a legacy for Marcus Aurelius. In response, Marcus Aurelius dispatched Lucius Verus to the eastern regions. The Roman army succeeded in recovering the Kingdom of Armenia and securing the threatened eastern frontier, achieving victory. During the campaign, however, an outbreak of plague first appeared on the eastern frontier and subsequently spread throughout much of the Roman world. This study aims to examine the impact of Marcus Aurelius’s eastern campaign on the socio-political situation of the Roman Empire.
