Rome's Gothic Wars_ From the Third Century to Alaric - Michael Kulikowski [53]
Constantius on the Danube
The greatest barbarian danger, as the narrative of Ammianus shows, lay along the Rhine and the upper Danube, where neglect and the civil war that followed the death of Constans had weakened the frontiers. Both Alamanni and Franks were restive and the latter even succeeded in sacking so important a town as the imperial residence of Trier. Constantius, the last surviving heir of Constantine, was a deeply suspicious man, mistrustful of everyone, not least his own family. But he could not govern alone, certainly not with simultaneous disturbances on Rhine, Danube and eastern front, and even a suspect cousin was preferable to another usurper like Magnentius. Constantius turned to his only surviving male relatives, but the caesar Gallus, Julian’s elder brother, proved a disaster and soon met his end at the hands of the executioner. In 356, Julian alone remained and was duly appointed caesar. For half a decade, he campaigned more or less continuously along and beyond the Rhine. Constantius, meanwhile, devoted himself to the Sarmatians and Quadi of the middle Danube in year after year of campaigning. In 358 and 359, Constantius conducted massive punitive raids against Sarmatians and Quadi, and then against the Sarmatians’ former subjects the Limigantes. Deliberately sowing terror, Constantius sat in judgement on the many petty kings of the region, allocating territories to different groups.[97] As a result of these campaigns, the Sarmatians were eliminated as a serious power in the barbaricum. What is more, the suppression of the Limigantes created a sort of no-man’s land opposite the Danube bend between the powerful Quadic chieftains to the northwest and the Tervingian ones to the south and east. Both Quadi and Tervingi were to benefit.
Gothic power was presumably rendered all the more stable by these campaigns. Certainly neither Constantius, nor later Julian, ever felt the need to campaign along the ripa Gothica of the lower Danube, which was entirely peaceful between the 330s and the 360s. That peace allowed for the trade relations advertised in the name of a little fort called Commercium – ‘the marketplace’ – and for the recruitment of Gothic soldiers into the garrisons on the imperial side of the river.[98] Such garrison troops are probably responsible for the fairly widespread distribution of Sântana-de-Mureş/Černjachov decorative styles in places like Iatrus south of the frontier, and we know that Constantius was
