Moore complexity: the Visigoths didn't necessarily invade Roman Gaul or Iberia but were resettled there after their time in Rome, which wasn't the Roman capital when they sacked it. In 418, [Western Roman emperor] Honorius rewarded his Visigothic federates by giving them land in Gallia Aquitania on which to settle ... and eventually were invited into Spain by a Roman usurper in the autumn of 409 .... This was probably done under hospitalitas, the rules for billeting army soldiers. The settlement formed the nucleus of the future Visigothic kingdom that would eventually expand across the Pyrenees and onto the Iberian peninsula. That Visigothic settlement proved paramount to Europe's future as had it not been for the Visigothic warriors who fought side by side with the Roman troops under general Flavius Aetius, it is perhaps possible that Attila would have seized control of Gaul, rather than the Romans being able to retain dominance. https://en.wikipedia.org/wiki/Visigoths https://en.wikipedia.org/wiki/Visigoths
