Indirectly Bouvines was almost as important in the history of England as in that of France. John returned to England foiled, and in great anger; he resolved to give up the French war, secured a truce with King Philip by abandoning his attempt to reconquer his lost lands on the Loire, and turned to attack the recalcitrant subjects who had refused to join him in his late campaign beyond the Channel. Matters soon came to a head: on hearing that the king was mobilizing his mercenary bands, the barons met at Bury St Edmunds, and leagued themselves by an oath to obtain from the king a confirmation of the charter of Henry I. (November 1214). At the New Year they sent him a formal ultimatum, to which he would not assent, though he opened up futile negotiation with them through the channel of the archbishop, who did not take an open part in the rising. At Easter, nothing having been yet obtained from the king, an army headed by five earls, forty barons, and Giles Braose, bishop of Hereford, mustered at Stamford and marched on London. Their captain was Robert FitzWalter, whom they had named "marshal of the army of God and Holy Church." When they reached the capital its gates were thrown open to them, and the mayor and citizens adhered to their cause (May 17). The king, who had tried to turn them back by taking the cross and declaring himself a crusader, and by making loud appeals for the arbitration of the pope, was forced to retire to Windsor. He found that he had no supporters save a handful of courtiers and officials and the leaders of his mercenary bands; wherefore in despair he accepted the terms forced upon him by the insurgents. On the 15th of June 1215 he sealed at Runnymede, close to Windsor, the famous _Magna Carta_, in face of a vast assembly among which he had hardly a single friend. It is a long document of 63 clauses, in which Archbishop Langton and a committee of the barons had endeavoured to recapitulate all their grievances, and to obtain redress for them. Some of the clauses are unimportant concessions to individuals, or deal with matters of trifling importance--such as the celebrated weirs or "kiddles" on Thames and Medway, or the expulsion of the condottieri chiefs Gerard d'Athies and Engelhart de Cigogné. But many of them are matters of primary importance in the constitutional history of England. The Great Charter must not, however, be overrated as an expression of general constitutional rights; to a large extent it is a mere recapitulation of the claims of the baronage, and gives redress for their feudal grievances in the matters of aids, reliefs, wardships, &c., its object being the repression of arbitrary exactions by the king on his tenants-in-chief. One section, that which provides against the further encroachments of the king's courts on the private manorial courts of the landowners, might even be regarded as retrograde in character from the point of view of administrative efficacy. But it is
