Athanaric

Athanaric or Atanaric (Latin: Athanaricus; died 381) was king of several branches of the Thervingian Goths (Latin: Thervingi) for at least two decades in the 4th century. Throughout his reign, Athanaric was faced with invasions by the Roman Empire, the Huns and a civil war with Christian rebels. He is considered the first king of the Visigoths, who later settled in Iberia, where they founded the Visigothic Kingdom.
