Gothic revolt of Theodoric I

The uprising took place between 425 and 426, in the period shortly after the death of usurpator John and was terminated by a military operation under the command of Aëtius.[1] The cause of the uprising must be sought on the one hand in the settlement of the Goths in Gallia Aquitania close to the Gallic capital Arles by Constantius III and was intended to keep an eye on the senatorial nobility.In the previous period he should have campaigned against a series of usurpers (including Constantine and Jovinus) who received much support from the Gallic elite.Nevertheless, with the establishment of the Goths, Constantius had created a new power group that sought more influence within late Roman Gaul.[4] With the death of Constantius III in 421 and of Honorius in 423, the Western Roman Empire ended up in a new crisis that would have major consequences for the relationship between imperial power and the army.Because the emperor was still a child, the western part of the empire was governed by mother Galla Placidia who was strongly under the influence of her generals.The policies of the Western Roman Emperor Honorius had always relied heavily on the work of his brother-in-law Constantius, who had been appointed co-emperor seven months earlier.[8] Theoderic withheld Castinus from the support of the Visigothic auxiliary troops, as a result of which he suffered a heavy defeat in the battle of Tarraco in Baetica against Gunderic, the king of the Vandals who thus became the undisputed masters of Hispania.He accepted Valentinian III as emperor and was given the high position of praefectus praetorio per Gallia, entrusting him with the rule of Gaul and Spain.Aetius' appointment as chief executive in Gaul is seen as a maneuver by the new regime to keep a potential troublemakers away from the central government.
