unity of Christendom. The miserable reign of his worthless successor, Edward II, illustrated the importance of the personal factor in the monarchy, and also showed how incapable the barons were of supplying the place of the feeblest king. Both parties failed because they took no account of the commons of England or of national interests. The leading baron, Thomas of Lancaster, was executed; Edward II was murdered; and his assassin, Mortimer, was put to death by Edward III, who grasped some of the significance of his grandfather's success and his father's failure. He felt the national impulse, but he twisted it to serve a selfish and dynastic end. It must not, however, be supposed that the Hundred Years' War originated in Edward's claim to the French throne; that claim was invented to provide a colourable pretext for French feudatories to fight their sovereign in a war which was due to other causes. There was Scotland, for instance, which France wished to save from Edward's clutches; there were the English possessions in Gascony and Guienne, from which the French king hoped to oust his rival; there were bickerings about the lordship of the Narrow Seas which England claimed under Edward II; and there was the wool-market in the Netherlands which England wanted to control. The French nation, in fact, was feeling its feet as well as the English; and a collision was only natural, especially in Guienne and Gascony. Henry II had been as natural a sovereign in France as in England, because he was quite as much a Frenchman as an Englishman. But since then the kings of England had grown English, and their dominion over soil which was growing French became more and more unnatural. The claim to the throne, however, gave the struggle a bitter and fruitless character; and the national means, which Edward employed to maintain the war, only delayed its inevitably futile end. It was supported by wealth derived from national commerce with Flanders and Gascony; national armies were raised by enlistment to replace the feudal levy; the national long-bow and not the feudal war- horse won the battles of Crecy and Poitiers; and command of the sea secured by a national navy enabled Edward to win the victory of Sluys and complete the reduction of Calais. War, moreover, required extra supplies in unprecedented amounts, and they took the form of national taxes, voted by the House of Commons, which supplemented and then supplanted the feudal aids as the mainstay of royal finance.
