End of the Frankish Empire - The Carolingian Civil War

　　This mighty change in the course of Teutonic destiny, this breakdown of the Frankish empire, was wrought by two destroying forces, one from within, one from without. From within came the insubordination, the still savage love of combat, the natural turbulence of the race. It is conceivable that, had Charlemagne been followed on the throne by a son and then a grandson as mighty as he and his immediate ancestors, the course of the whole broad earth would have been altered. The Franks would have grown accustomed to obey; further conquest abroad would have insured peace at home; the imperial power would have become strong as in Roman days, when the most feeble emperors could not be shaken. But the descendants of Charlemagne sank into a decline. He himself had directed the fighting energy of the Franks against foreign enemies. His son and successor had no taste for war, and so allowed his idle subjects time to quarrel with him and with one another. The next generation, under the grandsons of Charlemagne, devoted their entire lives to repeated and furious civil wars, in which the empire fell apart, the flower of the Frankish race perished, and the strength of its dominion was sapped to nothingness.
