To the south of Clovis' new acquisitions in Gaul lay the kingdom of the Arian West Goths, to the southeast that of another heretical German people, the Burgundians. Gregory of Tours reports him as saying: "I cannot bear that these Arians should be in possession of a part of Gaul. Let us advance upon them with the aid of God; after we have conquered them let us bring their realms into our power." So zealous was the newly converted king that he speedily extended his power to the Pyrenees, and forced the West Goths to confine themselves to the Spanish portion of their realm. The Burgundians became a tributary nation and soon fell completely under the rule of the Franks. Then Clovis, by a series of murders, brought portions of the Frankish nation itself, which had previously been independent of him, under his scepter. [Sidenote: Character of Frankish history.] 14. When Clovis died in 511 at Paris, which he had made his residence, his four sons divided his possessions among them. Wars between rival brothers, interspersed with the most horrible murders, fill the annals of the Frankish kingdom for over a hundred years after the death of Clovis. Yet the nation continued to develop in spite of the unscrupulous deeds of its rulers. It had no enemies strong enough to assail it, and a certain unity was preserved in spite of the ever-shifting distribution of territory among the members of the royal house.[19] [Sidenote: Extent of the Frankish kingdoms in the sixth century.] The Frankish kings succeeded in extending their power over pretty nearly all the territory that is included to-day in France, Belgium, and the Netherlands, as well as over a goodly portion of western Germany. By 555, when Bavaria had become tributary to the Frankish rulers, their dominions extended from the Bay of Biscay to a point east of Salzburg. Considerable districts that the Romans had never succeeded in conquering had been brought into the developing civilization of western Europe. [Illustration: The Dominions of the Franks under the Merovingians] [Sidenote: Division of the Frankish territory into Neustria, Austrasia, and Burgundy.] As a result of the divisions of the Frankish lands, fifty years after the death of Clovis three Frankish kingdoms appear on the map. Neustria, the western kingdom, with its center at Paris or Soissons, was inhabited mainly by the older Romanized people among whom the Franks had settled. To the east was Austrasia, with Metz and Aix-la-Chapelle as its chief cities. This region was completely German in its population. In these two there was the prophecy of the future France and Germany. Lastly, there was the old Burgundian realm. Of the Merovingian kings, as the line descended from Clovis was called, the last to rule as well as reign was Dagobert (d. 638), who united the whole Frankish territory once more under his scepter.
