Louis XXIV
Le Roi Soleil
Rome didn't fall, it faded away. The fall of the empire was probably less disruptive then when Sulla or Octavian took power (since there was prescription and stuff). Theodoric in Rome used the same government institutions as before. In Gaul, the Galic-Roman aristocrats shifted allegience to the Franks and became part of their nobles without problem. It was only in places like Spain, North Africa, and England where the barbarians were extremely disruptive that Rome disapeared.
