Wallia or Valia (in Spanish: Walia, in Portuguese Vália), (c. 385 – 419) was king of the Visigoths from 415 to 419, earning a reputation as a great warrior and prudent ruler. He was elected to the throne after Athaulf and then Sigeric were assassinated in 415. In 418 he honored the alliance by invading Hispania, where his army destroyed the Siling Vandals and so reduced the numbers of Alans living there that the survivors placed themselves under the rule of Gunderic, king of the Asding Vandals.
