The Visigoths formed inside the Roman empire between 376 and 418, sacked Rome in 410, and ruled a kingdom from Toulouse and then Toledo that produced the earliest surviving Germanic law code and lasted until 711.
The Visigoths were the Gothic people who came together inside the Roman empire between the Danube crossing of 376 and the Aquitaine settlement of 418, and who went on to rule a kingdom for nearly three centuries — from Toulouse, and after 507 from Toledo. They are the Gothic people who solved the problem the other one did not: the religious and legal division between a Gothic military elite and a far larger Roman population, which they closed deliberately, by dated acts, in the century between 580 and 654.
Their kingdom ended abruptly when Roderic was killed in 711 and Toledo fell, but their legal and political legacy did not. The Liber Iudiciorum was still being used in Iberian courts as the Fuero Juzgo six hundred years later, and northern Iberian kings spent centuries claiming to be the Goths' heirs. The polity lasted three hundred years; the claim to be its successor lasted twice that.
The Visigoths had no distinct endonym. They called themselves Goths, and every attempt to find a separate self-designation runs into that fact. Visigothi is not a name they used of themselves in the fourth century: it appears as a fixed term with Cassiodorus, paired with Ostrogothi as a matched set of "western" and "eastern" Goths, and Jordanes passes the arrangement on to everyone who read him afterwards.
Modern scholars generally reject the compass-point etymology. Vesi or Visi, which does appear in fourth-century Latin sources such as the Notitia Dignitatum and in Claudian, is treated as the older and possibly self-applied name, perhaps meaning something like "the good" or "the noble" Goths. The tidy western-and-eastern pairing is a sixth-century literary convenience laid over two peoples who had formed separately and at different times.
Ammianus' name for the group north of the lower Danube in the fourth century is Tervingi. The conventional equation of Tervingi with Visigoths is useful shorthand and inexact in a way that matters: the people who received land in Aquitaine in 418 included Greuthungi, Alans and others absorbed during forty years of movement and war, and the group that crossed the river in 376 was not the group that settled.
This is where the scholarly disagreement is sharpest, and the article names it rather than flattening it. Kulikowski argues that the Visigoths were created inside the empire and that a distinct pre-Danube Visigothic people is a retrojection from later sources. Heather allows more continuity, seeing a Tervingian core that held through 376 and re-formed around Alaric. Wolfram proposes a Traditionskern, a leading group carrying genuine tradition that others joined. Halsall and Pohl stress that the identity was situational, asserted more strongly at some moments than others. What all of them accept is that the years from 376 to 418 were formative; what they dispute is how much existed before them.
The Visigoths originate as a political community in the crisis of 376, not in Scandinavia. Tervingi under Fritigern and Alavivus crossed the Danube under Hunnic pressure, Roman mismanagement of the refugees turned them into an army, the destruction of the eastern field army at Adrianople in 378 gave them a bargaining position no barbarian group had held before, and the treaty of 382 gave them a legal existence inside the empire.
Consolidation came under Alaric I, raised as king in 395, who welded the treaty Goths and others into a force that could negotiate with both imperial courts and be ignored by neither. His Italian campaigns were checked by Stilicho at Pollentia in 402 and Verona in 403, but three blockades of Rome from 408 ended in the sack of 24 to 27 August 410 — three days that shook the Roman world's sense of itself and prompted Augustine to begin The City of God. Alaric died in southern Italy later the same year.
The final steps were territorial and dynastic. Athaulf moved the Goths into Gaul and married the emperor's sister Galla Placidia at Narbonne in 414, in a ceremony staged with deliberate Roman propriety — a bid for Gothic-Roman fusion at the highest possible level. Wallia then campaigned in Spain against Vandals and Alans on Rome's behalf, and the settlement of 418 in Aquitania Secunda made the Goths a people with land, a capital at Toulouse and a frontier. Expansion under Euric from 466 took most of southern Gaul and much of Hispania; it reversed at Vouillé in 507, where Clovis killed Alaric II and pushed the kingdom south of the Pyrenees for good.
One mechanism at the heart of the Visigothic settlement is genuinely unresolved, and it deserves flagging rather than smoothing. The traditional view is that the Goths received real shares of land, sortes, taken from Roman proprietors — a dispossession, however orderly, of the existing landowning class.
Walter Goffart argued in 1980 that they instead received assignments of tax revenue, which would make the settlement an administrative act carried out through the existing fiscal machinery rather than a transfer of estates. The debate has not been settled, and it is not a technicality: the two models imply completely different relationships between the incoming Gothic elite and the Roman landowners they lived among.
The consequences run through everything else on this page. If the Goths took land, the Hispano-Roman aristocracy had a standing grievance and the later fusion of the two populations is more surprising than it looks. If they took revenue, the settlement gave the Roman landowning class a reason to keep the fiscal system running and the Gothic elite a reason to protect it. The same uncertainty applies to the Gothic settlement in Italy, which is why it recurs in the Ostrogothic case.
Visigothic kingship was elective in principle and violently contested in practice. Gregory of Tours called king-killing the morbus Gothorum, the disease of the Goths, and the phrase is quoted so often because the record broadly supports it: a substantial proportion of Visigothic kings were deposed or murdered, and no dynasty established itself securely enough to make succession routine.
After 589 the institution that tried to fix this was the Councils of Toledo, which combined bishops with the lay magnates of the palace and legislated on secular as well as church matters. The Fourth Council of 633, presided over by Isidore of Seville, regulated royal election, condemned usurpation and bound the nobility by oath. It was an attempt to solve a political problem by making the church the guarantor of legitimacy.
It worked imperfectly, and the cost was structural. The monarchy became dependent on episcopal and aristocratic consent for its own legitimacy, which meant that a king who lost the confidence of the councils lost the argument about whether he was lawfully king at all. Administration itself ran on late Roman lines throughout — an officium palatinum of household officers, dukes over provinces and counts over cities — so the instability sat at the top of an otherwise functioning structure.
Until 589 the kingdom contained two complete and parallel churches. The Homoian church of the Goths had its own bishops, its own clergy and its own baptism, and it rebaptised converts coming from the Nicene church — the practice that made the division a fact of ordinary experience rather than a dispute among theologians. The Hispano-Roman population was Nicene and had its own long-established hierarchy, wealth and networks.
The political cost was continuous. A Gothic king could not be the religious head of most of his subjects. Nicene bishops were natural channels for the influence of a hostile foreign power, which mattered increasingly once the eastern empire held the south-eastern coast from 552. And any Gothic dissident could acquire a ready-made constituency simply by changing sides in the religious argument.
This was not a background condition but an active fault line, and every serious crisis of the sixth century ran along it. The kingdom that emerged after 589 was not more religious than the one before; it was one in which the rulers and the ruled could belong to the same institution.
