Excerpts from Books and Wikipedia
". . . by adopting Roman Catholicism [rather than Germanic Arianism], Clovis was able to win the hearts and minds of those peoples that he came to lead after his conquests on the battlefield. Also, Clovis indirectly ensured that the united Frankish kingdom would be linked to the papacy and to what remained of the empire, thus retaining much of the old Roman culture and easing the transition for the conquered. Despite embracing Roman Catholicism, Clovis was unable to conquer Burgundy, although he did restrict the Visigoth influence to Spain. Before his death in 511, Clovis added Aquitaine to his kingdom, with Paris as his capital. Unfortunately, Clovis's united kingdom was divided again at this death between his four sons who ruled the regions of Paris, Orleans, Soissons, and Rheims. [1001 Days]
