When the Germanic peoples invaded the provinces of the Roman Empire, the hordes, urged forward by the pressure of the Huns in their rear, hurled themselves for the first time upon the Pyrenean Peninsula – the Alani, a people of Scythian, or Tatar, race; the Vandals and Suebians, Germanic races. The Alani were, for the most part, quickly brought into subjection. The Vandals, after establishing themselves in Baetica, to which they gave the name of Vandalusia (Andalusia), passed on into Africa, while the Visigoths hemmed in the Suebi in Galicia until the latter were completely brought under control. These Visigoths, or Western Goths, after sacking Rome under the leadership of Alaric (410), turned towards the Iberian Peninsula, with Athaulf for their leader, and occupied the northeastern portion. Wallia extended his rule over most of the peninsula, keeping the Suebians shut up in Galicia. Theodoric I took part, with the Romans and Franks, in the Battle of the Catalaunian Plains, where Attila was routed.
