The Viking raids never ceased during the reign of Charles. The civil war of 893-8 had given the Danes an opportunity of returning to Neustria, and they were not slow to take it. When the chroniclers of the time are not recounting the rebellions of Charles's undutiful subjects, they are generally occupied in detailing Danish ravages. But it is now to be observed that the inroads of the Vikings are not nearly so dangerous to the realm as they had once been the spell of the invincibility of the Northmen had been broken, and whenever they appeared they were fiercely withstood by the local counts and dukes. The land no longer gave them such rich prey, for the open towns had now surrounded themselves with walls, and were not as formerly the defenceless victims of every raider who could muster a few hundred men at his back. Still the invaders never ceased to come, for many of their former fields of action were now closed in England Alfred and his son were too strong for them, and in Germany they never had their old good fortune after their great defeat at Louvain. France, therefore, had now to bear the brunt of their attacks, and all their hordes concentrated themselves on the coast between the Scheldt and the Garonne.

It was in 911 that Charles the Simple took a step which was to change the aspect of the great struggle with Hrolf on the the Danes. Their main army was now lying on Seine, 910-11. the lower Seine, and their chief camp was at Rouen, a great city which they had sacked and desolated and made their own. Their war-lord was now the sea-king Hrolf, or Rollo as the Franks called him, who had asserted his power by right of superior ability above all the other jarls. Hrolf's bands ranged far and wide in the Seine valley, and had fought at Chartres a bloody but indecisive battle with the host of the Franks, headed by the king's greatest vassals, the dukes of France and Burgundy and the count of Poitou.

Despairing, as Alfred had despaired thirty years before, of ever being able to drive away the Dane, Charles took the same step that the great king of Wessex had taken. He

determined to offer the Viking leader a great tract of land as a settlement for his followers, if he would consent to draw them all together and to conclude a stable peace. The experiment had been made before by the Frankish monarchs, with no encouraging results, and the tale of Charles the Fat and king Godfred must have been fresh in the minds of the Vikings. Nevertheless the offer was made once more: if Hrolf would settle down, he should have an ample Danelagh-as the English would have called it—for his men. Charles proffered him Rouen and the lower valley of the Seine, and with them the hand of his daughter Gisela. The Northman blustered and affected to despise the king's offer, but presently he began to haggle and to speak of terms. The monarch of the West Franks and the veteran sea-king met at Clair-sur-Epte, and there the bargain was concluded. Hrolf asked Treaty of Clair-sur- and received all the lands from the river Epte to Epte, 911. the sea, a grant which the Danes interpreted as giving them all the coast-land from the mouth of the Somme to the borders of Brittany. Charles added to this the easy promise of the suzerainty of Brittany itself, when Hrolf should succeed in conquering the unruly princes of that land, who for many years had paid no allegiance to the Frankish crown.

The Viking therefore received the hand of the king's daughter, promised to submit to baptism, and 'became the man' of Charles the Simple. A well-known story tells how Hrolf refused to bow the knee himself to the Frank, when the oath of homage had to be given, and deputed one of his chiefs to be his proxy, and how the Dane, with designed clumsiness, when he bent before the king's feet, succeeded in upsetting king and throne together. But Charles overlooked the insult in return for the tangible benefits that the submission of Hrolf involved, and loaded the Danes with gifts on their departure.

The Viking chief therefore settled down to live as a Frankish The Duchy duke at Rouen: he had himself baptized, accordof Normandy. ing to his promise, and the majority of his warriors followed his example. Contrary to what might have been

expected, the experiment of planting the Northmen on the lower Seine proved a complete success for the Frankish king. The majority of the Danish war-bands in Gaul drifted, one after the other, to join Hrolf's followers, and to receive from him a fixed settlement in his new duchy. By sacrificing a part of his realm, Charles the Simple had saved the rest. The duke of Normandy, no longer rex piratarum, but the king's trusted vassal, was on the whole very faithful to the oaths that he had sworn at Clair-sur-Epte. He adhered to king Charles in all his troubles, and sent him a contingent of Danes whenever he was asked for aid. It was only when Charles had been deposed by rebels that Hrolf again turned loose his plundering bands upon France, and became once more the scourge of Neustria.

The summer of 912 saw Charles both freed from his Viking war by the cession of Normandy, and hailed as king of Lotharingia by the Austrasians. The next eight years were the most fortunate period of his reign: he waged no important wars abroad, and had no very serious troubles at home. But his authority over the greater part of France was very limited: more especially in the lands south of the Loire nothing but lip-service was granted him: neither tribute nor military aid could be expected from the great counts of the South. Yet weak as he was, Charles the Simple was still stronger than his great vassals cared that he should be. Three of the greatest magnates of his realm resolved to compass his deposition : their chief was Robert duke of France, who in his old age began to covet the crown that he had refused to claim in 899. His confederates were Rudolf, second duke of Burgundy, and Heribert count of Vermandois. They commenced their operations by bidding the king dismiss his chief Rebellion minister and favourite, count Hagano. When of Robert he refused, they sent him a formal disavowal of of France. their allegiance, and after a space proclaimed Robert of France king of the West Franks.

Civil war at once began: supported by the Lotharingians

and the Normans king Charles made head against the rebels, though they raised against him all the warriors of France and Burgundy. The armies met at Soissons for a decisive engagement: the troops of the Karling were beaten, but in the moment of victory the rebel king was pierced by a Norman lance, and by Robert's death the rising was left without a leader (923).

Continued civil wars.

The great vassals were cowed for a moment by their chief's fall, and sorely distracted by a Danish invasion. Rollo had launched against the territories of the rebel dukes a great horde of Northmen, and the invaders were joined by a fresh army from England under Regnald, whom Edward the Elder had just deposed from the kingship of Northumbria. But in spite of the ravages of the Danes, who swarmed into Burgundy, and threatened to establish a second Danelagh in the valley of the Saone, the rebels resolved not to submit to their rightful lord. They now proclamed as anti-king Rudolf duke of Burgundy, for Hugh, son of Robert of France, refused to take up his father's claims. Charles might have fought down the insurrection, for a great Norman army was coming to his aid, if he had not fallen by treachery. Heribert of Vermandois offered to submit to him, and begged him to come to a conference at Peronne. The simple king hastened to the meeting, and was seized and thrown into a dungeon (923). The only drop of bitterness in the cup of the rebels was that Edgiva, the English wife of Charles, escaped with her son Lewis to the court of her father king Edward the Elder. There was still an heir of the Karling house safe beyond the seas.

For four troubled years Rudolf of Burgundy reigned as king of France, and Charles the Simple lay in durance at Peronne. Rudolf was but a phantom king: Aquitaine refused to acknowledge him: the Danes ranged all over his realm and beset his native duchy of Burgundy with especial fury. His own confederates in the rebellion paid him scanty homage, and went each on his own way. After a space

Heribert of Vermandois quarrelled with Rudolf, and to spite the new king drew Charles out of his dungeon and proclaimed him once more monarch of the West Franks. But Rudolf bought over the double traitor to rejoin him and for a second time Heribert seized the person of his natural lord and master. This time Charles did not escape with mere imprisonment: the cruel and treacherous count starved Murder of him to death at Peronne. At last Rudolf the Charles the Burgundian could call himself without dispute Simple, gag. king of France (929).

Here we must leave the history of the western realm, at a moment when it had reached much the same wretched condition that Germany attained at the time of the death of Conrad 1. More unhappy than their eastern neighbours, the Franks of Neustria and Aquitaine were not yet to see any such great rulers as Henry the First and Otto the Great set over them. They were destined to drink the cup of feudal anarchy to the dregs, ere a strong monarchy was once more to arise among them. The fight between the Karlings and the dukes of France was to drag on for two generations more, ere Hugh Capet finally gained the crown that his grandfather Robert and his great-uncle Odo had worn. And when the house of the dukes of France had seized the throne, they were to be for long ages as powerless as the Karlings whom they had supplanted.

As yet the only favourable symptom in the condition of France was the comparative immunity from Viking raids that it was beginning to enjoy. Thanks to the feudal horseman and the feudal castle, thanks still more to the narrowing of Danish ambition to the Norman duchy and its neighbouring lands of Maine and Brittany, the kingdom was beginning to enjoy a certain measure of peace from the outer enemy. Unfortunately the great vassals of the crown only used their opportunity to redouble their wicked feuds, and the nation's worst foes were to be those of its own household for many a long day.
