The Byzantines established an occidental province, Spania, in the south, with the intention of reviving Roman rule throughout Iberia. Eventually, however, Hispania was reunited under Visigothic rule. 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. Euric (466), who put an end to the last remnants of Roman power in the peninsula, may be considered the first monarch of Spain, though the Suebians still maintained their independence in Galicia. Euric was also the first king to give written laws to the Visigoths. In the following reigns the Catholic kings of France assumed the role of protectors of the Hispano-Roman Catholics against the Arianism of the Visigoths, and in the wars which ensued Alaric II and Amalaric lost their lives.
