5. Euric (466-484). This reign was the culminating point of the Visigothic monarchy in Gaul. Euric led expeditions beyond the Loire against the Armoricans; in 474, he conquered Auvergne, which was then ceded to him by treaty; he had already conquered Arles and Marseilles, so that the monarchy of the Visigoths then extended from the Pyrenees to the Loire, and from the Ocean to the Alps, thus adjoining the monarchies of the Burgundians and Ostrogoths. Euric had also extended his dominions into Spain, where he possessed the Tarragonese district and Bœtica, which he had conquered from the Suevi. Euric had the laws and customs of the Goths written in a book. A passage of Sidonius Apollinarius which speaks of _Theodoricianæ leges_, has led to the belief that Theodoric commenced this collection; but Euric is also called Theodoric. 6. Alaric II. (484-507.) This reign was the epoch of the decay of the Visigothic monarchy in Gaul. Alaric, less warlike than his predecessors, gave himself up to the pursuit of pleasure. He was defeated by Clovis, at Vouillé near Poitiers, and left dead on the field. The Franks in the east, and the Burgundians in the west, dismembered the Visigothic monarchy, which thus became reduced to Languedoc, properly so called, and a few districts adjacent to the Pyrenees. {209} The Breviarium Aniani. Alaric did for his Roman subjects what Euric had done for the Goths. He collected and revised the Roman laws, and formed them into a code called the _Codex Alaricianus_. This code was based upon the _Codex Theodosianus_ published in 438 by Theodosius the Younger, and upon the _Codex Gregorianus_, the _Codex Hermogenianus_, the _Pauli Sententiæ_, and the _Constitutiones Imperiales_, published subsequently to the reign of Theodosius. This code was also called the _Breviarium Aniani_. It has been thought that Anianus, the referendary of Alaric, was its principal editor; but Père Sirmond has proved that Anianus only published it by order of the king, and sent authentic copies of it into the provinces. By an act of Alaric, the Roman legislation was, so to speak, revived, rearranged, and adapted to the monarchy of the Goths. It thenceforth emanated from the Gothic king himself. In the north of Gaul, whilst the Barbarian laws ceased to be customs and became written laws, the Roman laws lost their force as a whole, and became customs; in the south, on the other hand, they remained written laws, and retained much greater power, exercising an important influence upon the laws of the Barbarians. It would appear that this twofold written legislation must tend necessarily to maintain the separation of the two nations; but it contributed on the contrary to bring it to an end.
