Aftermath

Alaric was succeeded in the command of the Gothic army by his brother-in-law, Ataulf, who married Honorius' sister Galla Placidia three years later. Following in the wake of Alaric's leadership, which Kulikowski claims, had given his people "a sense of community that survived his own death...Alaric's Goths remained together inside the empire, going on to settle in Gaul. There, in the province of Aquitaine, they put down roots and created the first autonomous barbarian kingdom inside the frontiers of the Roman empire." The Goths were able to settle in Aquitaine only after Honorius granted the once Roman province to them, sometime in 418 or 419. Not long after Alaric's exploits in Rome and Athaulf's settlement in Aquitaine, there is a "rapid emergence of Germanic barbarian groups in the West" who begin controlling many western provinces. These barbarian peoples included: Vandals in Spain and Africa, Visigoths in Spain and Aquitaine, Burgundians along the upper Rhine and southern Gaul, and Franks on the lower Rhine and in northern and central Gaul.
