The Decline of Roman Power in the West – J.B. Bury

Synopsis:

In The Invasion of Europe by the Barbarians, historian J.B. Bury offers a narrative account of the deluge of barbarian invasions – and mass migrations – which afflicted the Roman Empire in the fifth century AD. Bury also chronicles the early evolution of the barbarian kingdoms in Western Europe throughout late antiquity.

The chapter Bury dedicates to the decline of Roman power in the western half of the empire centers on institutional collapse of the state, and the ensuing snowball of barbarianization within the Roman army. Barbarianization of the army thus allowed for the eventual consummation of an Italian kingdom under the rule of the barbarian warlord Odovacar.

Excerpts:

“The contribution which the Vandals made to the shaping of Europe was this: the very existence of their kingdom in Africa, and of their naval power in the Mediterranean, acted as a powerful protection for the growth of the new German kingdoms in Gaul and Spain, and ultimately helped the founding of a German kingdom in Italy, by dividing, diverting, and weakening the forces of the Empire. The Vandals had got round, as it were, to the rear of the Empire; and the effect of their powerful presence there was enhanced by the hostile and aggressive attitude which they continuously adopted.

“He (Ricimer) became through circumstances an emperor-maker; and his difficulty was this. If he set up too strong a man, his own power would have probably been overridden; his own fall would have been the consequence; while on the other hand weak upstarts were unable to maintain their position for any length of time, since public opinion did not respect them.

“It is also to be noted that in the intervals between the reigns of the emperors whom Ricimer set up and pulled down, when there was no emperor regnant in Italy, it did not mean that there was no emperor at all. At such times the imperial authority was entirely invested in the eastern emperor who reigned at Constantinople, the Emperor Leo; and this, too, was fully acknowledged by Ricimer, who indeed selected two of his emperors by arrangement with Leo.

“Odovacar had statesmanlike qualities, and he decided against the system of Ricimer, which had proved thoroughly unsatisfactory and unstable. His idea was to rule Italy under the imperial authority of Constantinople, unhampered by a second emperor in Italy, whom recent experiences had shown to be worse than useless. There would have been no difficulty for Odovacar in adopting this policy, if there had existed no second emperor at the time; but Julius Nepos was still alive, and, what was most important, he had been recognized at Constantinople.

“Odovacar was not hampered, as Ricimer had been, by the nominal authority of a resident emperor; he was able to pursue his own policy without any embarrassment, and to act as an independent ruler. His policy was one of peace; he was entirely averse from aggression. It must be noted, too, that his position was much easier than that of Ricimer, because the Vandal hostilities had ceased. Gaiseric had died in 477; and two years before his death he had made peace with Rome, and Odovacar had induced him to restore Sicily in return for a yearly payment.

Theodosius and the Antibarbarian Reaction – Alessandro Barbero

Synopsis:

The Battle of Adrianople in 378 often signals a key crossroad in the history of the late Roman Empire, but Alessandro Barbero lays out a somewhat different narrative in his book The Day of the Barbarians. Barbero examines the event within a three century context, and chronicles the cultural evolution of Roman civilization leading up to the battle – as well as the civilizational reaction following the final peace agreement with the Goths. As Roman power began to decline in the fifth century, the long ignored aristocracy of Rome began to reassert itself by becoming the foremost voice of the anti-barbarian reaction.

Excerpts:

“In the dissatisfaction that the Greek East felt at the political and military hegemony of the Latin West lay the seeds of competition – if not hostility – between the two parts of the Roman Empire; those seeds would not fail to produce fruit.

“All the rhetoric about the universality of the empire, about its capacity for assimilation, was trotted out to demonstrate that Theodosius had made the right choice. And, to be clear, it wasn’t all empty rhetoric; to a certain degree, that capacity for assimilation genuinely existed.

“The army, which was a community, seemed like the perfect machine for handling this integration process. It absorbed barbarians, ground them down, and transformed them into Roman veterans, into the men whom emperors in their public discourses addressed as ‘comrades in arms’ and who constituted the real pillar of the empire.

“In certain regions of the empire, where the mercenaries had completely replaced the units of the regular army, the change was reflected in the language itself: In Syriac, starting at the end of the fourth century, the word for ‘soldier’ became Goth.

“Most people ultimately shared the assumptions about the empire’s ability to assimilate the barbarians but resisted granting them too much power too quickly and thereby abdicating the civilizing mission of the empire.

The Defense Strategy of the Late Roman Empire – Arther Ferrill

Synopsis:

Defense strategy in the Roman Empire following the Crisis of the Third Century evolved considerably from the earlier preclusive security apparatus of Hadrian – which emphasized a synthesis of passive and active defense along mostly static lines of effort. Arther Ferrill credits the Emperor Constantine with the transition from the preclusive ideal to a novel defense-in-depth approach, which offered weakened frontier defenses in favor of large mobile field armies. This new model Roman army allowed more centralized control for the Emperor – as well as greater personal security – but with a vastly less controlled border region for the Empire.

Excerpts:

“Such obvious advantages, reflecting organization of war-making capacity far beyond that of Rome’s potential opponents, gave the Roman armies a psychological edge, a superiority in morale, often sufficient in itself to deter hostile military action. In the great days of the second century, with an army of about 300,000, the Romans defended an empire of some 50,000,000 people living in the Mediterranean basin.

“More than anything else Roman grand strategy in the High Roman Empire was based on the tactical superiority of the Roman army against all potential foes. To that extent the famous walls and fortresses can be misleading. The army, not the walls or forts, defended the frontiers.

“Roman grand strategy of the second century was predicated on political stability – preclusive security requires the presence of the legions on the frontiers. Civil war and rebellion, especially when they became endemic, diverted legions from the frontiers to the interior, creating marvelous opportunities for enemies across the border. That is what happened in the third century.

“The big change in Roman grand strategy came with Constantine the Great. As Zosimus claimed in the passage quoted above, Constantine organized a large mobile field army (probably 100,000 or more), stationed centrally, by withdrawing units from the frontiers, leaving them in a weakened condition. Zosimus saw this modification of traditional Roman grand strategy as catastrophic, an interpretation endorsed by Gibbon.

“The worst feature of the defense-in-depth is that inevitably the central mobile army will become an elite force and the frontier defenders merely second rate actors in defense policy. Troops that are not expected to defeat the enemy can hardly be blamed for wanting to avoid him altogether.
