Rome's Gothic Wars_ From the Third Century to Alaric - Michael Kulikowski [10]
Explaining the Third-Century Invasions
As the past few pages have demonstrated, the earliest evidence for Gothic invasions of the empire is not well enough attested to allow for much analysis, but that does not mean we should underestimate its impact. The letter of Gregory Thaumaturgus gives us a rare glimpse into just how traumatic the repeated Gothic raids into Asia Minor and other Greek provinces could be. But it does not answer basic questions of causation: what drove these Gothic raids, what made them a repeated phenomenon? The Graeco-Roman sources are content to explain barbarian attacks on the empire with an appeal to the fundamentals of nature itself: to attack civilization is just what barbarians do. That sort of essentialist explanation can hardly be enough for us. Rather, we need to seek explanations in the historical context. Now it happens that the third century was a period of massive change in the Roman empire, which saw the culmination of social and political developments that had been set in motion by the expansion of the Roman empire in the course of the first and second centuries A.D. Against this background, the first appearance of the Goths and the Gothic raids of the third century become comprehensible. Roman expansion had transformed the shape of Europe and the Mediterranean basin. It affected not just the many people who became Romans for the first time, but also the political constitution of the empire and even the many different peoples who lived along the imperial frontiers. One by-product of these changes was a cycle of internal political violence in the third-century empire that produced and then exacerbated the instability of the imperial frontiers.
The Roman empire had been a monarchy since the end of the first century B.C., when Augustus (r. 27 B.C.–A.D. 14), the grand-nephew and adoptive heir of Julius Caesar, put an end to a full generation of civil war that had ripped the Roman Republic apart. Augustus brought peace to the empire, but it came at the expense of the free competition amongst the Roman elite that had created a Roman empire to begin with. In its place, Augustus
