512 THE HISTORY OF MEDIEVAL EUROPE Moreover, this so-called " Hundred Years War" was not exactly a century in duration, but covered the period from x 337 to I 453- On the other hand, the number of years of actual warfare were much less than a hundred, since in the course of this period there were numerous long truces and two treaties of peace intended to put a stop to hostilities entirely. But at the time usually accepted as the end of the war there was no treaty. Finally, the causes of the reopen- ing of hostilities in 1337 between Edward III and Philip VI were not new, but the old problems of Guienne, Flanders, and Scotland over which Edward I and Philip IV had fought already. In 1328 the direct male line of the Capetians expired and the French had to determine to whom of the royal family The French ^e crown should go.

But a few years later the inevitable quarrel with France over Guienne, and the Scottish and Flemish questions, led Edward III in 1337 to lay claim to the French crown and declare war. One of the first acts of Philip VI had been to aid the Count of Flanders and to wipe out the disgrace of the de- Opening feat °f Courtrai by the victory of Cassel over the t y h?"aJ ^emish in 1328. But now there was a demo- cratic uprising led by Jacob Artevelde of Ghent, the power of the count was overthrown, and the Flemish towns made an alliance with Edward III.
