William de Valence, Henry's half-brother and chief favourite, brought matters to extremity, and determined the former to give full scope to his long-cherished schemes of ambition, which the laws and the royal authority had hitherto with no little difficulty restrained.
He secretly called an assembly of the most powerful nobles, particularity Humphrey of Hereford, high constable; Roger of Norfolk, earl marshal; and the Earls of Warwick and Gloucester—men who, by their exalted rank and immense possessions, stood first in the rank of English nobility.
To this assembly he exposed the necessity of reforming the state, and entrusting the execution of the laws to other hands than those which had proved themselves, by bitter experience, so totally unfitted for the charge confided to them. In his harangue he did not forget to inveigh against the oppression exercised against the lower orders, or exaggerate on the violations of the privileges of the barons, and the depredations committed on the clergy; and, in order to aggravate the enormity of his brother-in-law's conduct, he appealed to the great charter, which Henry had so often sworn to maintain and so frequently violated.
This violation, he urged, with great show of justice, of privileges which their ancestors had wrung from the crown by an enormous sacrifice of blood and treasure, ought not to be endured, unless they were prepared to set the seal upon their own degeneracy by permitting such important advantages to be torn from them by a weak prince and his insolent foreign favourites. To all suggestions of a remonstrance the speaker replied by observing that the king's word had been too frequently broken, although confirmed by oaths, ever again to be relied upon, and that nothing short of his being placed in a position of utter inability to violate the national privileges could henceforth ensure the regular observance of them.
These complaints, which were founded in truth, accorded so entirely with the sentiments of the assembly, that they produced the desired effort, and the barons pledged themselves to a resolution of reducing the public grievances, by taking into their own hands the administration of the kingdom.
Henry having summoned a parliament, in expectation of receiving supplies for his Sicilian project, the barons appeared in the hall, clad in complete armour, and with their swords by their side. The king, on his entry, struck with the unusual appearance, asked them what was their purpose, and whether they intended to make him their prisoner. Roger Bigod replied, in the name of the rest, that he was not their prisoner, but their sovereign; that they even intended to grant him large supplies, in order to fix his son on the throne of Sicily; that they only expected some return for this expense and service; and that, as he had frequently made submissions to the parliament, had acknowledged his past errors, and still allowed himself to be carried into the same path, which gave them such just reason of complaint, he must now yield to more strict regulations, and confer authority on those who were able and willing to redress the national grievances. Henry, partly allured by the hopes of supply, partly intimidated by the union and martial appearance of the barons, agreed to their demand; and promised to summon another parliament at Oxford, in order to digest the new plan of government, and to elect the persons who were to be entrusted with the chief authority.
This parliament, which the royalists, and even the nation, from experience of the confusions that attended its measures, afterwards denominated the mad parliament, met on the day appointed; and as all the barons brought along with them their military vassals, and appeared with an armed force, the king, who had taken no precautions against them was in reality a prisoner in their hands, and was obliged to submit to all the terms which they were pleased to impose upon him. Twelve barons were selected from among the king's ministers, twelve more were chosen by parliament: to these twenty-four, unlimited authority was granted to reform the state; and the king himself took an oath that he would maintain whatever ordinances they should think proper to enact for that purpose. Leicester was at the head of this supreme council, to which the legislative power was thus in reality transferred; and all their measures were taken by his secret influence and direction. The first step bore a specious appearance, and seemed well calculated for the end which they professed to be the object of all these innovations: they ordered that four knights should be chosen by each county; that they should make inquiry into the grievances of which their neighbourhood had reason to complain, and should attend the ensuing parliament, in order to give information to that assembly of the state of their particular counties—a nearer approach to our present constitution than had been made by the barons in the reign of King John, when the knights were only appointed to meet in their several counties, and there to draw up a detail of their grievances. Meanwhile the twenty-four barons proceeded to enact some regulations as a redress of such grievances as were supposed to be sufficiently notorious: they ordered that three sessions of parliament should be regularly held every year, in the months of February, June, and October; that a new sheriff should be annually elected by the votes of the freeholders in each county; that the sheriffs should have no power of fining the barons who did not attend their courts or the circuits of the justiciaries; that no heirs should be committed to the wardship of foreigners, and no castles entrusted to their custody; and that no new warrens or forests should be created, nor the revenues of any counties or hundreds be let to farm. Such were the regulations which the twenty-four barons established at Oxford, for the redress of public grievances.
But the Earl of Leicester and his associates, having advanced so far to satisfy the nation, instead of continuing in this popular course, or granting the king that supply which they had promised him, immediately provided for the extension and continuance of their own authority. They roused anew the popular clamour which had long prevailed against foreigners; and they fell with the utmost violence on the king's half-brothers, who were supposed to be the authors of all national grievances, and whom Henry had no longer any power to protect. The four brothers, sensible of their danger, took to flight, with an intention of making their escape out of the kingdom; they were eagerly pursued by the barons. Aymer, one of the brothers, who had been elected to the see of Winchester, took shelter in his episcopal palace, and carried the others along with him they were surrounded in that place, and threatened to be dragged out by force, and to be punished for their crimes and misdemeanours; and the king, pleading the sacredness of an ecclesiastical sanctuary, was glad to extricate them from this danger by banishing them the kingdom.
