The extension of Clovis’s kingdom, his overthrow of the Visigothic power, his partial conquest of the Burgundians, would have been even more rapid and decisive but for the opposing diplomacy of the great Arian ruler, Theodoric the Ostrogoth, whose prestige and power even the bold Frank dared not defy. Moreover, the Burgundians stood well with their Roman subjects, whom they treated generously, and permitted to live under a code of Roman law. When it came to war between them and Clovis, the advantage rested with the latter; but possibly the fear of Theodoric, or the pressure of war with the Alemanni, deferred the final conquest of the Burgundian kingdom for another generation. In 507 Clovis attacked the Visigothic kingdom, and incorporated it with his dominions in the course of the next year. Whether or not he had cried out, in the words of Gregory of Tours, “it is a shame that these Arians should hold a part of Gaul; let us attack them with God’s help and take their land,” at all events the war had a religious sanction, and its successful issue was facilitated by the Catholic clergy within the Visigothic territory. Clovis’s career was now nearing its end. In his last years, by treachery, murder, and open war when needed, he made himself king of all the Franks, Ripuarian and Salian. The intense partisan sympathy of the Church for this its eldest royal Teuton son speaks in the words of Gregory of Tours, concluding his recital of these deeds of incomparable villainy: “Thus day by day God cast down his (Clovis’s) enemies before him, because he did what was right in His eyes”! The unresting sons and grandsons of Clovis not only conquered Burgundy, but extended their rule far to the east, into the heart of Germany, and Merovingians became masters of Thuringia and Bavaria. That such a realm should hold together was impossible. From Clovis to Charlemagne it was the regular practice to divide the realm at death among the ruler’s sons, and for the ablest among them to pursue and slay the others, and so unite the realm again. Besides this principle of internecine conflict, differences of race and language and degrees of Latinization ensured eventual disruption.
