Ancient Rome’s Most Important Civil Wars: The History of the Conflicts that Destroyed the Roman Republic and Split the Roman Empire

Summary

Caesar is still remembered for winning a civil war and helping bring about the end of the Roman Republic, leaving a line of emperors in its place, but it’s quite possible that none of what Caesar did would’ve happened without the template for such actions being set 40 years earlier. At the time, when Caesar was in his teens, war was being waged both on the Italian peninsula and abroad, with domestic politics pitting the conservative, aristocratic optimates against the populist, reformist populares, and this tension ultimately escalated into an all-out war. One of the leading populares was Caesar’s uncle, Gaius Marius, a military visionary who had restructured the legions and extended the privileges of land ownership and citizenship to legionaries on condition of successful completion of a fixed term of service. In the late 2nd century B.C., Marius had waged a successful campaign against several Germanic tribes, and after earning eternal fame in the Eternal City, Marius was appointed a consul several times. In 88 B.C., he entered into conflict with his erstwhile protégé, the optimate Sulla, over command of the army to be dispatched against Mithridates VI of Pontus, a long-time enemy of Rome and its Greek allies.  

The 50 years following the assassination of Severus Alexander on March 19, 235 A.D. has been generally regarded by academics as one of the lowest points in the history of the Roman Empire. This stands in stark contrast to the previous 150 years, which included the reigns of the Five Good Emperors and has been universally praised as one of the high points of the empire. Severus Alexander was the last of the Severan emperors, and the subsequent years of crisis were characterized by a series of short reigns, usually ending in the violent death of the reigning emperor.
