They turned the power of the purse to little or no account; they discredited themselves in the eyes of the nation by giving proofs of feebleness and indecision in the first great crisis with which they were called to deal, the interregnum of anarchy and conspiracy that ensued upon the capture of King John at Poitiers (1356). The result was that the States General, occasionally summoned to endorse the policy or register the decrees of the monarchy, remained an ornamental feature of the French constitution. In England, on the other hand, the Commons accepted the position of auxiliaries to the superior Estates in their contests with the Crown; and the new Parliament pursued the aims and the tactics of the old Great Council, with all the advantages conferred by an exclusive right to grant taxation. For more than two hundred years it was a popular assembly in form and in pretension alone. The most active members of the Lower House were drawn from the lower ranks of the territorial aristocracy; and the Commons were bold in their demands only when they could attack the prerogative behind the shield of a faction quartered in the House of Lords. But the alliance of the Houses transformed the character of English politics. Before Parliament had been in existence for two centuries, it had deposed five kings and conferred a legal title upon three new dynasties; it had indicated to posterity the lines upon which an absolutism could be fought and ruined without civil war; and it had proved that the representative element in the constitution might overrule both monarchy and aristocracy, if it had the courage to carry accepted principles to their logical conclusion.
