The deposition of Edward the Second proclaimed to the world the power which the English Parliament had gained. In thirty years from their first assembly at Westminster the Estates had wrested from the Crown the last relic of arbitrary taxation, had forced on it new ministers and a new system of government, had claimed a right of confirming the choice of its councillors and of punishing their misconduct, and had established the principle that redress of grievances precedes a grant of supply. Nor had the time been less important in the internal growth of Parliament. Step by step the practical sense of the Houses themselves completed the work of Edward by bringing about change after change in its composition. The very division into a House of Lords and a House of Commons formed no part of the original plan of Edward the First; in the earlier Parliaments each of the four orders of clergy, barons, knights, and burgesses met, deliberated, and made their grants apart from each other. This isolation however of the Estates soon showed signs of breaking down. Though the clergy held steadily aloof from any real union with its fellow-orders, the knights of the shire were drawn by the similarity of their social position into a close connexion with the lords. They seem in fact to have been soon admitted by the baronage to an almost equal position with themselves, whether as legislators or counsellors of the Crown. The burgesses on the other hand took little part at first in Parliamentary proceedings, save in those which related to the taxation of their class. But their position was raised by the strifes of the reign of Edward the Second when their aid was needed by the baronage in its struggle with the Crown; and their right to share fully in all legislative action was asserted in the statute of 1322. From this moment no proceedings can have been considered as formally legislative save those conducted in full Parliament of all the estates. In subjects of public policy however the barons were still regarded as the sole advisers of the Crown, though the knights of the shire were sometimes consulted with them. But the barons and knighthood were not fated to be drawn into a single body whose weight would have given an aristocratic impress to the constitution. Gradually, through causes with which we are imperfectly acquainted, the knights of the shire drifted from their older connexion with the baronage into so close and intimate a union with the representatives of the towns that at the opening of the reign of Edward the Third the two orders are found grouped formally together, under the name of "The Commons." It is difficult to overestimate the importance of this change. Had Parliament remained broken up into its four orders of clergy, barons, knights, and citizens, its power would have been neutralized at every great crisis by the jealousies and difficulty of co-operation among its component parts.
