Under the reign of King John II, from 1355 to 1358, the Estates General had controlled not only the voting but, through their commissaries, the administration of and jurisdiction over the taxes. In the first half of the reign of Charles VII, they had been summoned almost every year and had dutifully voted subsidies for the Crown. But when the struggle was over, they renounced the power of the purse.
