[Sidenote: Causes of the Hundred Years’ War]
The question of the Salic Law is important because its different interpretations were the immediate excuse for opening hostilities between England and France in that long and weary struggle called the ‘Hundred Years’ War’. There were of course other and far deeper reasons. One of these reasons was that English kings had never forgotten or forgiven John’s expulsion from Normandy. They wanted to avenge this ignominious defeat and also Philip IV’s encroachments in the Duchy of Guienne, that, united to his policy of supporting the Scottish chieftains in their war of independence, had been a steady source of disaster to England since the beginning of the fourteenth century.
Because of his failure in Scotland and the revolts of his turbulent barons Edward II was murdered; and Edward III, taking warning from his father’s fate, welcomed the war with France, not merely in the hope of revenge and glory, but still more in order to find an occupation for the hot English blood that might otherwise in the course of its embittered feuds murder him.
He rode forth to battle, the hero of his court and of the chivalry of England; but no less, as it happened, the champion of her middle classes, who cheerfully put their hands in their pockets to pay for his first campaigns. The reason of their enthusiasm for this war was that Philip of Valois, in order to annoy his rival, had commanded his Flemish subjects to trade no longer with the English. Now English sheep were the best in Europe (so valuable that their export was forbidden lest another nation should obtain the breed), and English wool was the raw material of all others on which Flanders depended for the wealth and prosperity gained by her looms and factories. Before this time English kings had encouraged Flemish trade, establishing ‘Staple’ markets in certain towns under their protection, where merchants of both countries could meet and bargain over their wares. Wishing to retaliate on Philip VI, however, Edward III stopped the export of wool, though at the same time he offered good terms and advantages to any of the manufacturers of Bruges and Ghent who might care to settle in Norfolk or on the East Coast and set up factories there as English subjects.
