At the same time, the attitude even of Henry III. towards Magna Carta indicates a distinct advance upon that of his father. It was much that the advisers of John’s infant heir solemnly accepted, on behalf of the Crown, the provisions of the Charter, and strove to enforce them during the minority; and it was even more that Henry, on attaining majority, confirmed the arrangement thus arrived at, freely and on his own initiative, and found himself thereafter unable openly to repudiate the bargain he had made. Yet the settlement of the dissensions between Crown and baronage was still nominal rather than real. In the absence of proper constitutional machinery, the king was merely bound by bonds of parchment which he could break at pleasure. The victory of the friends of liberty proved a hollow one, since unsupported promises count for little in the great struggles fought for national liberties. Even the crude constitutional devices of the Charter of 1215 entirely disappeared from its confirmations; and, in the absence of all sanctions for its enforcement, the Charter became an empty expression of good intentions. If a quarrel arose, no constitutional expedient existed to reconcile the disputants—nothing to obviate a final recourse to the arbitrament of civil war. Thus, part of the blame for the recurring and devastating struggles of the reign of Henry III. must be attributed to the defects of the Great Charter. The whole interest of the reign indeed lies in the various attempts made to evolve adequate machinery for enforcing the liberties contained in Magna Carta. Experiments of many kinds were tried in the hope of turning theory into practice. The system of government outlined in the Provisions of Oxford of 1258, for example, reproduced the defects of the crude scheme contained in chapter 61 of the Great Charter, and added new defects of its own. It sought to keep the king in the paths of good government by the coercion of a body of his enemies. This baronial committee was not designed to enter into friendly co-operation with Henry in the normal work of government, but rather to supersede entirely his right to exercise certain of the royal prerogatives. No glimmering was yet apparent of the true solution afterwards adopted with success. It was not yet realized that the best way to control the Crown was through the agency of its own ministers, and not by means of a hostile opposition organized for rebellion—that the correct policy was to make it difficult for the king to rule except through regular ministers, and to secure that all such ministers should be men in whom the _Commune Concilium_ reposed confidence and over whom it exercised control.
