The Visigothic Kingdom, Visigothic Spain or Kingdom of the Goths occupied what is now southwestern France and the Iberian Peninsula from the 5th to the 8th centuries. One of the Germanic successor states to the Western Roman Empire, it was originally created by the settlement of the Visigoths under King Wallia in the province of Gallia Aquitania in southwest Gaul by the Roman government and then extended by conquest over all of Hispania. The Kingdom maintained independence from the Eastern Roman or Byzantine Empire, whose attempts to re-establish Roman authority in Hispania were only partially successful and short-lived.

The Visigoths were a Germanic people united under the rule of a king and living within the Roman Empire during late antiquity. The Visigoths first appeared in the Balkans, as a Roman-allied barbarian military group united under the command of Alaric I. Their exact origins are believed to have been diverse but they probably included many descendants of the Thervingi who had moved into the Roman Empire beginning in 376 and had played a major role in defeating the Romans at the Battle of Adrianople in 378. Relations between the Romans and Alaric's Visigoths varied, with the two groups making treaties when convenient, and warring with one another when not. Under Alaric, the Visigoths invaded Italy and sacked Rome in August 410.
