later, Aetius settled the Burgundians in the region, under King Gondioc which became part of the Kingdom of the Burgundians. His son, Chilperic II, ruled Valence from 473 to 493 when he was slain by his brother Gundobad. Chilperic's daughter Clotilde married Clovis, the King of the Franks, in 493. Clovis's son Childebert I attacked the Burgundians in 534, adding their territory to the Frankish Kingdom. The city then fell successively under the power of the Franks, the Arabs of Spain, the sovereigns of Arles, the emperors of Germany, the counts of Valentinois, the counts of Toulouse, as well as its own bishops, who struggled to retain the control of the city they had won in the fifth century. These bishops were often in conflict with the citizens and the counts of Valentinois and to strengthen their hands against the latter the pope in 1275 united their bishopric with that of Die. The citizens put themselves under the protection of the dauphin, and in 1456 had their rights and privileges confirmed by Louis XI and put on an equal footing with those of the rest of Dauphiné, the bishops consenting to recognize the suzerainty of the dauphin. In the 16th century Valence became the centre of Protestantism for the province in 1563. The town was fortified by King Francis I. It became the seat of a celebrated university in the middle of the 15th century; but the revocation of the Edict of Nantes in 1685 struck a fatal blow at its industry, commerce and population. Toponymy The conquest of Gaul by Julius Caesar made the Rhône corridor a major north-south communication axis, linking with the new Roman possessions around the Mediterranean Sea. Many settlements were founded, including Valentia, a Latin name meaning La Vaillante [brave], La Vigoureuse [strong], in the territory of the . The town named Valença in Occitan, Valènço in literary Provençal and Valinço in local Provençal. Heraldry Antiquity At the end of prehistory The city of Massalia, long on good terms with Rome, asked it for help against the Salyes who had ravaged its territory. The intervention of the Romans, from 125 BC, assured its safety but the war continued against the Allobroges, among whom the Salyes people had found refuge. In August 121 BC, the army of Quintus Fabius Maximus crushed them at the Battle of the Isère River (confluence of the Rhône and Isère) according
