Alaric II (Gothic: 𐌰𐌻𐌰𐍂𐌴𐌹𐌺𐍃, Alareiks, 'ruler of all'; Latin: Alaricus; c. 458/466 – August 507) was the King of the Visigoths from 484 until 507. He succeeded his father Euric as King of the Visigoths in Toulouse on 28 December 484; he was the great-grandson of the more famous Alaric I, who sacked Rome in 410. He established his capital at Aire-sur-l'Adour (Vicus Julii) in Aquitaine. His dominions included not only the majority of Hispania (excluding its northwestern corner) but also Gallia Aquitania and the greater part of an as-yet undivided Gallia Narbonensis.
