North Brabant in the Netherlands and parts of neighbouring provinces of Antwerp and Limburg in Belgium. This put them in the north part of the Roman civitas Tungrorum, with Romanized population still dominant south of the military highway Boulogne-Cologne. Later, Chlodio seems to have attacked westwards from this area to take control of the Roman populations in Tournai, then southwards to Artois, and Cambrai, eventually controlling an area stretching to the Somme river. Childeric I, Clovis's father, was reputed to be a relative of Chlodio, and was known as the king of the Franks that fought as an army within northern Gaul. In 463 he fought in conjunction with Aegidius, the magister militum of northern Gaul, to defeat the Visigoths in Orléans. Childeric died in 481 and was buried in Tournai; Clovis succeeded him as king, aged just 15. Historians believe that Childeric and Clovis were both commanders of the Roman military in the Province of Belgica Secunda and were subordinate to the magister militum. The Franks of Tournai came to dominate their neighbours, initially aided by the association with Aegidius. The death of Flavius Aetius in 454 led to the decline of imperial power in the Gaul; leaving the Visigoths and the Burgundians competing for predominance in the area. The part of Gaul still under Roman control emerged as a kingdom under Syagrius, Aegidius's son. Though no primary sources expounding on the language spoken by Clovis exist, historical linguist consider it likely that, based on his family history and core territories, he spoke a form of Old Dutch. In this, the early Merovingians can be contrasted with the later Carolingians, such as Charlemagne, of the late 8th century and onward, who probably spoke various forms of Old High German. Early reign (481–491) Road to Soissons The ruler of Tournai died in 481 and was succeeded by his sixteen-year-old son, Clovis. His band of warriors probably numbered no more than half a thousand. In 486 he began his efforts to expand the realm by allying himself with his relative, Ragnachar, regulus of Cambrai and another Frankish regulus, Chalaric. Together the triumvirate marched against Syagrius and met the Gallo-Roman commander at Soissons. During the battle Chalaric betrayed his comrades by refusing to take part in the fighting. Despite the betrayal, the Franks landed a decisive victory, forcing Syagrius to flee to the court of Alaric II. This battle is viewed as
