The most ancient of these kings, reigning over the principal tribe, who is known to us is Chlodio.[2] According to Gregory of Tours Chlodio dwelt at a place called Dispargum, which it is impossible to identify. Towards 431 he crossed the great Roman road from Bavay to Cologne, which was protected by numerous forts and had long arrested the invasions of the barbarians. He then invaded the territory of Arras, but was severely defeated at Hesdin-le-Vieux by Aetius, the commander of the Roman army in Gaul. Chlodio, however, soon took his revenge. He explored the region of Cambrai, seized that town, and occupied all the country as far as the Somme. At this time Tournai became the capital of the Salian Franks. After Chlodio a certain Meroveus (Merowech) was king of the Salian Franks. We do not know if he was the son of Chlodio; Gregory of Tours simply says that he belonged to Chlodio's stock--"de hujus stirpe quidam Merovechum regem fuisse adserunt,"--and then only gives the fact at second hand. Perhaps the remarks of the Byzantine historian Priscus may refer to Meroveus. A king of the Franks having died, his two sons disputed the power. The elder journeyed into Pannonia to obtain support from Attila; the younger betook himself to the imperial court at Rome. "I have seen him," writes Priscus; "he was still very young, and we all remarked his fair hair which fell upon his shoulders." Aetius welcomed him warmly and sent him back a friend and _foederatus_. In any case, eventually, Franks fought (451) in the Roman ranks at the great battle of Mauriac (the Catalaunian Fields), which arrested the progress of Attila into Gaul; and in the _Vita Lupi_, which, though undoubtedly of later date, is a recension of an earlier document, the name of Meroveus appears among the combatants. Towards 457 Meroveus was succeeded by his son Childeric. At first Childeric was a faithful _foederatus_ of the Romans, fighting for them against the Visigoths and the Saxons south of the Loire; but he soon sought to make himself independent and to extend his conquests. He died in 481 and was succeeded by his son Clovis, who conquered the whole of Gaul with the exception of the kingdom of Burgundy and Provence. Clovis made his authority recognized over the other Salian tribes (whose kings dwelt at Cambrai and other cities), and put an end to the domination of the Ripuarian Franks.
