The Breviary of Alaric (Breviarium Alaricianum or Lex Romana Visigothorum) is a collection of Roman law, compiled by unknown writers and approved by referendary Anianus on the order of Alaric II, King of the Visigoths, with the advice 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.
