The Burgundian princes found their chief support in the nobility, in a numerous class of officials, and in the municipal aristocracies. The nobles, transformed from a feudal caste to a court clique, even though they retained, as satellites of the monarch, much wealth and power, had relatively lost ground to the rising pretensions of the cities and of the commercial class. The clergy, too, were losing their old independence in subservience to a government which regulated their tithes and forbade their indulgence-trade. In 1515 Charles secured from Leo X and again in 1530 from Clement VII the right of nomination to vacant benefices. He was able to make of the bishops his tools and to curtail the freedom, jurisdiction, and financial privileges of the clergy considerably because the spiritual estate had lost favor with the people and received no support from them. As the two privileged classes surrendered their powers to the monarch, the third estate was coming into its own. Not until the war of independence, however, was it able to withstand the combination of bureaucracy and plutocracy that made common cause with the central government against the local rights of the cities and the customary privileges of the gilds. Almost everywhere the prince was able, with the tacit support of the wealthier burghers, to substitute for the officers elected by the gilds his own commissioners. [Sidenote: Revolt of Ghent] But this usurpation, together with a variety of economic ills for which the commoners were inclined, quite wrongly, to blame the government, caused general discontent and in one case open rebellion. The gilds of Ghent, a proud and ancient city, suffering from the encroachments of capitalism and from the decline of the Flemish cloth industry, had long asserted among their rights that of each gild to refuse to pay one of the taxes, any one it chose, levied by the government. [Sidenote: 1539] The attempt {237} of the government to suppress this privilege caused a rising which took the characteristically modern form of a general strike. The regent of the Netherlands, Mary, yielded at first to the demands of the gilds, as she had no means of coercion convenient. Charles was in Spain at the time, but hurried northward, being granted free passage through France by the king who felt he had an interest in aiding his fellow monarch to put down rebellious subjects. Early in 1540 Charles entered Ghent at the head of a sufficient army. He soon meted out a sanguinary punishment to the "brawlers" as the strikers were called, humbled the city government, deprived it of all local privileges, suppressed all independent corporations, asserted the royal prerogative of nominating aldermen, and erected a fortress to overawe the burghers. Thus the only overt attempt to resist the authority of Charles V, apart from one or two insignificant Anabaptist riots, was crushed.
