A Barracks emperor was a Roman Emperor
Roman Emperor
The Roman emperor was the ruler of the Roman State during the imperial period . The Romans had no single term for the office although at any given time, a given title was associated with the emperor...

. There were approximately fourteen barracks emperors in 33 years, producing an average reign of a little over two years apiece. The resulting instability in the imperial office and the near constant state of civil war and insurrection threatened to destroy the Roman Empire from within and left it vulnerable to attack from without.

Style of the 3rd century barracks emperors


Unlike previous emperors who had seized power in military coups d'état (Vespasian

, had begun his military career as an enlisted soldier. A barracks emperor could not boast of a distinguished family name or a successful career as a statesman or public servant; rather, he had only his military career to recommend himself, and his only influence was the points of his soldiers' swords.

Some of these soldier emperors were members of the equestrian class who had worked their way up to a sufficient position of influence within their legion that the soldiers would support a bid for the purple, although this was a risky undertaking because the soldiers could withdraw their support at any time and perhaps shift it to another military leader who looked more promising at the time.

Because the barracks emperors were frequently border commanders, the act of overthrowing the reigning emperor and seizing power for themselves left large gaps in the empire's border defenses, gaps that could be exploited by the Romans' enemies, leading to the Germanic incursion into Roman territory in the 260s and resulting in the construction of the Aurelian Walls

. The barracks emperors also used state money to pay their troops — no emperor who had come into power by force of arms could afford to allow his soldiers to become disaffected, as those who live by the sword die by the sword — and public works and infrastructure fell into ruin. To accommodate the vast demands of buying off their soldiers, the state often simply seized private property, damaging the economy and driving up inflation.
