When the Visigoths under Ataulf left Italy they passed into southern Gaul, and there established themselves with Toulouse as the centre of the Visigothic kingdom. They soon extended their rule to Spain, with the connivance of sundry Roman rulers. Some time before them Vandals, Suevi and Alans, having crossed the Rhine into Gaul, had been drawn across the Pyrenees by half-traitorous invitations of rival Roman governors. The Visigoths now attacked these peoples, with the result that the Suevi retreated to the north-west of the peninsula, and at length the restless Vandals accepted the invitation of the traitor Count Boniface, and crossed to Africa. Visigothic fortunes varied under an irregular succession of non-hereditary and occasionally murdered kings. Their kingdom reached its farthest limit in the reign of Euric (466-486), who extended its boundaries northward to the Loire and southward over nearly all of Spain.[138] Under the Visigoths the lot of the Latinized provincials, who with their ancestors had long been Roman citizens, was not a hard one. The Roman system of quartering soldiers upon provincials, with a right to one-third of the house, afforded precedent for the manner of settlement of the Visigoths and other Teuton invaders after them. The Visigoths received two-thirds not only of the houses but also of the lands, which indeed were bare of cultivators. The municipal organization of the towns was left intact, and in general the nomenclature and structure of Roman officialdom were preserved. As the Romans were the more numerous and the cleverer, they regained their wealth and social consideration. In 506, Alaric II. promulgated his famous code, the _Lex Romana Visigothorum_, usually called the “Breviarium,” for his Roman subjects. Although the next year Clovis broke down the Visigothic kingdom in Gaul, and confined it to narrow limits around Narbonne, this code remained in force, a lasting source of Roman law for the inhabitants of the south and west of Gaul.[139]
