The French succession in 1328.
The inevitable struggle between England and France was rendered the more serious by the claim made by Edward III that he was himself the rightful king of France. He based his pretensions upon the fact that his mother Isabella was the daughter of Philip the Fair. Philip, who died in 1314, had been followed by his three sons in succession, none of whom had left a male heir, so that the direct male line of the Capetians was extinguished in 1328. The lawyers thereupon declared that it was a venerable law in France that no woman should succeed to the throne. The principle was also asserted that a woman could not even transmit the crown to her son. Consequently Edward III appeared to be definitely excluded, and Philip VI of Valois, a nephew of Philip the Fair, became king.
Edward III claims the French crown.
At first Edward III, who was a mere boy in 1328, appeared to recognize the propriety of this settlement and did qualified homage to Philip VI for Guienne. But when it became apparent later that Philip was not only encroaching upon Edward's prerogatives in Guienne but had sent French troops to aid the Scotch, the English king bethought him of his neglected claim to the French crown.
The Flemish towns.
The advantage of publicly declaring himself the rightful king of France was increased by the attitude of the flourishing towns of Flanders. Philip VI had assisted the count of Flanders in a bitter struggle to prevent the towns from establishing their independence. Consequently the Flemish burghers now announced their willingness to desert Philip and acknowledge and aid Edward as their king.
Commercial relations between the Flemish towns and England.
English wool.
Flanders at this period was the most important trading and manufacturing country in western Europe. Ghent was a great manufacturing town, like Manchester to-day, and Bruges a busy port, like modern Antwerp or Liverpool. All this prosperity was largely dependent upon England, for it was from there that the Flemish manufacturers procured the fine, long wool which they wove on their looms into cloth and spun into yarn. In 1336 the count of Flanders, perhaps at Philip's suggestion, ordered the imprisonment of all the Englishmen in Flanders. Edward promptly retaliated by prohibiting the export of wool from England and the importation of cloth. At the same time he protected and encouraged the Flemish artisans who had emigrated across the Channel and were carrying on their industry in the county of Norfolk.
