As the sunset is often the most beautiful hour of the day, so the splendour of the old Flemish communes reached its zenith at the moment when many of them were about to sink into their long sleep. This was the period of Burgundian rule. Upon the death of Louis of Maele the County of Flanders ceased to be a separate sovereignty, as it had been since Baldwin of the Iron Arm, for the husband of Margaret, the old Count's daughter, was Duke of Burgundy and brother of the King of France--a foreign prince whose interests in France far out-weighed in his mind his interests in Flanders. The new ruler, Philip the Bold, was acknowledged as Count of Flanders in 1384, but was only able to enter Audenaerde by stratagem after a siege, and was defied openly by the sturdy burghers of Ghent. The following year, however, Philip effected a family union by which he virtually controlled the two important States of Brabant and Hainaut. His eldest son was married to Margaret, daughter of the Regent of Hainaut, while the latter's son married Philip's daughter. These marriages were celebrated at Cambrai, in April, 1385, and at the same time the Duchess of Brabant recognised Philip's second son as heir to the Duchy. Brabant at that time was less rich and powerful than Flanders, but its chief cities, Brussels and Louvain, were growing rapidly. Hainaut, on the other hand, had been termed by one of its leaders "a poor country of proud men"--its chief cities, Mons and Valenciennes, being places of third-rate importance, and its present vast mineral wealth then undreamed of. The marriages of Cambrai are worth remembering, however, as explaining the rapidity with which the House of Burgundy extended its sway over nearly all of what is now Belgium. Ghent still resisted its new Count, but an army of one hundred thousand French and Burgundians--gathered primarily to invade England--destroyed the seaport of Damme, which had been rebuilt since its previous destruction by the French, and plundered "the Four Trades," as the fertile region thereabout was called. Ghent, however, had suffered enough to make it sue for peace and acknowledge Philip's sovereignty. The invasion of England project came to nothing--as have so many others before and since--but it had at least enabled Philip to establish his power in Flanders.
