It was an age of turbulence in Europe, and the violence of predatory invaders brought woes upon many peoples. On the east of Charles' empire the Hungarians, successors of the Huns, began to threaten. In the midst of all these distractions and dangers, assailed by enemies without and within, Charles found it a task far beyond his abilities to construct a state upon foundations of unity. He bore many titles and held several crowns, but his actual dominion was narrowly restricted, and his nominal subjects were in a state of political subdivision almost amounting to dismemberment. After various futile efforts during his later years to unify his empire, Charles died from an illness which seized him in 877, on his return to France from a fruitless campaign of subjugation and pillage in Italy. In the subsequent division of the empire, according to the terms of the treaty of Verdun, the several portions included Italy, the nucleus of France, and that of the present Germany. Already suffering from the devastating expeditions of the Norse or Northmen, the Carlovingian empire, now weakened by division, became an easier prey for the invaders. Emboldened by success, the Northmen at length commenced to settle in the regions they invaded, no longer returning, as formerly, to their northern homes in winter. Among chieftains of the early Norman invaders who settled in France was Hastings, who became Count of Chartres; later came Rou, Rolf, or Rollo the Rover, to whom Charles the Simple of France gave Normandy, whence sprang the conquerors and rulers of England, who laid the foundation of the English-speaking nations of today.) The first of Charlemagne's grand designs, the territorial security of the Gallo-Frankish and Christian dominion, was accomplished. In the East and the North, the Germanic and Asiatic populations, which had so long upset it, were partly arrested at its frontiers, partly incorporated regularly in its midst. In the South, the Mussulman populations which, in the eighth century, had appeared so near overwhelming it, were powerless to deal it any heavy blow. Substantially France was founded. But what had become of Charlemagne's second grand design, the resuscitation of the Roman Empire at the hands of the barbarians that had conquered it and become Christians? Let us leave Louis the Debonair his traditional name, although it is not an exact rendering of that which was given him by his contemporaries. They called him Louis the Pious. And so, indeed, he was, sincerely and even scrupulously pious; but he was still more weak than pious, as weak in heart and character as in mind; as destitute of ruling ideas as of strength of will, fluctuating at the mercy of transitory impressions or surrounding influences or positional embarrassments. The name of _Débonnaire_ is suited to him; it expresses his moral worth and his political incapacity both at once.
