Duke Robert, of Normandy, who died in 1035, was succeeded by his young son William, who bore in youth the opprobrious name of "the Bastard," but who extinguished it in later life under the proud appellation of "the Conqueror." By reason of his bastardy he was not an acceptable successor, and, being yet a boy, it seemed little likely that he would maintain himself on the ducal throne. Normandy, for a dozen years, was given up to lawless strife among its nobles. In 1047 a large part of the duchy rose in revolt, against its objectionable young lord. "It will be remembered that the western part of Normandy, the lands of Bayeux and Coutances, were won by the Norman dukes after the eastern part, the lands of Rouen and Evreux. And it will be remembered that these western lands, won more lately, and fed by new colonies from the North, were still heathen and Danish some while after eastern Normandy had become Christian and French-speaking. Now we may be sure that, long before William's day, all Normandy was Christian, but it is quite possible that the old tongue may have lingered on in the western lands. At any rate there was a wide difference in spirit and feeling between the more French and the more Danish districts, to say nothing of Bayeux, where, before the Normans came, there had been a Saxon settlement. One part of the duchy in short was altogether Romance in speech and manners, while more or less of Teutonic character still clave to the other. So now Teutonic Normandy rose against Duke William, and Romance Normandy was faithful to him. The nobles of the Bessin and Cotentin made league with William's cousin Guy of Burgundy, meaning, as far as one can see, to make Guy Duke of Rouen and Evreux, and to have no lord at all for themselves. … When the rebellion broke out, William was among them at Valognes, and they tried to seize him. But his fool warned him in the night; he rode for his life, and got safe to his own Falaise. All eastern Normandy was loyal; but William doubted whether he could by himself overcome so strong an array of rebels. So he went to Poissy, between Rouen and Paris, and asked his lord King Henry [of France] to help him. So King Henry came with a French army; and the French and those whom we may call the French Normans met the Teutonic Normans in battle at Val-ès-dunes, not far from Caen. It was William's first pitched battle," and he won a decisive victory. "He was now fully master of his own duchy; and the battle of Val-ès-dunes finally fixed that Normandy should take its character from Romance Rouen and not from Teutonic Bayeux. William had in short overcome Saxons and Danes in Gaul before he came to overcome them in Britain. He had to conquer his own Normandy before he could conquer England. … But before long King Henry got jealous of William's power, and he was now
