415 Hard pressed by the Romans Atawulf goes to Spain and conquers Barcelona. He is murdered. Sigeric succeeds him, reigning only a few days. Wallia succeeds. He makes a treaty of alliance with Honorius and receives territory in southern Gaul, under Roman supremacy, and the Visigothic kingdom of Tolosa [Tolosa (Toulouse) the capital] is founded. This alliance, the first sign of fusion between the Latin and German people, may be said to mark the beginning of the modern world.
THE VISIGOTHIC KINGDOM IN FRANCE AND SPAIN (415-711 A.D.)
At the time of foundation of the Visigothic kingdom there exist two states established by the barbaric peoples—the Suevi and the Vandals, who, as we have seen, invaded and settled in Spain (409). The Suevi have six kings until they are reduced by the Visigoths in 469. Godigisdus or Modigisdus and his son Gunderic rule the Vandals until 425, when Genseric, brother of Gunderic succeeds. In 429 Genseric, on invitation it is said of Boniface the Roman governor of Africa, leads the whole of his people and a portion of the Alani to Carthage (see kingdom of the Vandals in Africa).
415-418 Wallia as the ally of Rome wages war on the Vandals, Suevi, and Alani in Spain.
420 Theodoric I, son of Alaric, elected king on death of Wallia. The Visigoths begin to free themselves from Rome.
429 The Vandals leave for Africa.
439 Defeat of the Romans by Theodoric at Tolosa. Treaty of peace with Avitus.
451 The Romans and Visigoths unite against the invasion of Attila, king of the Huns. Defeat of Attila, at battle of Châlons in which Theodoric falls. His son Torismond succeeds.
452 Torismond killed by his brother, Theodoric II.
456 As the ally of Rome, Theodoric crosses into Spain and nearly exterminates the Suevi in battle near Astorga. He strengthens his own power and makes no attempt to restore the country to Rome.
