<P> The Visigoths, after the Sack of Rome (410) under Alaric I, were settled by the Romans in Aquitaine in 418 as foederates . Periodically they marched on Arles, the seat of the praetorian prefect but were always pushed back . In 437 they signed a treaty with the Romans which they kept . In 451 they provided one - third of the army of other tribes and Romans which defeated the Huns confederation of Eastern peoples led under Attila at the Battle of the Catalaunian Plains . they were by their king Theodoric I in 451 . They became independent of the Empire under his son, Euric who extended their territory over most of the Iberian peninsula and Gaul in the 460s and 470s . In 507, the Visigoths were pushed into Hispania by the Frankish Kingdom following the Battle of Vouillé in which the combined forces of Franks and Burgundians fell on them . They were able to retain Narbonensis and Provence after the timely arrival of an Ostrogoth detachment sent by Theodoric the Great . By the late 6th century, the Visigoths had converted to Catholicism . Their kingdom fell and was progresively conquered from 711 when the Muslim Moors defeated their last kings Roderic and Ardo (ruling until 724 over Catalonia and Narbonne) during the Umayyad conquest of Hispania . Some nobles found refuge in the mountain areas of the East Pyrenees and Cantabrian West and founded different autonomous realms, as Gothia, Pamplona and the Kingdom of Asturias in 718, they all began later to regain control under the leadership of the Visigothic nobleman Pelagius of Asturias, whose victory at the Battle of Covadonga (c. 722) it is taken to be the earliest at the centuries - long Reconquista . It was from the Asturian kingdom that some parts of modern Spain and Portugal evolved . These Goths never became completely Romanized as they became rather,' Hispanicized' . A completely different body of Society which they were pivotal to transform, from the Late Empire provincial polity with which they merged to into the Medieval entity stratified as an aristocratic Society under a strong centralist Monarchy and even stronger Christian Church for both peoples hitherto differentiated by Laws into a new Code, albeit different from the Feudal World that will devolve into later in France and other parts of Western Europe, organized around Germanic aristocracies too . They were widespread over a very a large territory and body of population, and however isolated or separated on the first centuries by customs, laws and religion practices in this fashion progressively adopted new ones retaining little of their original culture except for practical military customs, some artistic expressions and families traditions, as heroic songs and other folklore including Germanic names still in use in present - day Spain give ample evidence . In the late 6th Century Goths settled as foederati in parts of Asia Minor . Their descendants, who formed the elite Optimatoi regiment, still lived there in the early 8th Century . While they were largely assimilated, their Gothic origin was still well - known: the chronicler Theophanes the Confessor calls them Gothograeci . </P> <P> Christopher I. Beckwith suggests that the entire Hunnic thrust into Europe and the Roman Empire was an attempt to subdue independent Goths in the west . It is possible that the Hunnic attack came as a response to the Gothic eastwards expansion . </P> <P> In the 4th century, the Greuthungian king Ermanaric became the most powerful Gothic ruler, coming to dominate a vast area of the Pontic Steppe which possibly stretched from the Baltic Sea to the Black Sea as far eastwards as the Ural Mountains . Ermanaric's dominance of the Volga - Don trade routes made historian Gottfried Schramm consider his realm as a forerunner of the Viking founded state of Kievan Rus' . Ermanaric later committed suicide, and the Greuthungi fell under Hunnic dominance . </P> <P> In 454 AD, the Ostrogoths successfully revolted against the Huns at the Battle of Nedao and their leader Theoderic the Great invaded what is now Italy in 488 and settled his people there, founding an Ostrogothic Kingdom which eventually gained control of the whole Italian peninsula . </P>
