Alaric II, eighth king of the Visigoths, promulgates the Breviary of Alaric (Breviarium Alaricianum or Lex Romana Visigothorum), a collection of "Roman law".

Alaric II 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 in Aquitaine. His dominions included not only the majority of Hispania but also Gallia Aquitania and the greater part of an as-yet undivided Gallia Narbonensis.

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.

The Breviary of Alaric is a collection of Roman law, compiled by Roman jurists and issued by referendary Anianus on the order of Alaric II, King of the Visigoths, with the approval of his bishops and nobles. It was promulgated on 2 February 506, the 22nd year of his reign. It applied, not to the Visigothic nobles who lived under their own law, which had been formulated by Euric, but to the Hispano-Roman and Gallo-Roman population, living under Visigoth rule south of the Loire and, in Book 16, to the members of the trinitarian Catholic Church; the Visigoths were Arian and maintained their own clergy.

Roman law is the legal system of ancient Rome, including the legal developments spanning over a thousand years of jurisprudence, from the Twelve Tables, to the Corpus Juris Civilis ordered by Eastern Roman emperor Justinian I.
