But nothing forwarded this confederacy so much as the concurrence of Langton, Archbishop of Canterbury; a man whose memory, though he was obtruded on the nation by a palpable encroachment of the see of Rome, ought always to be respected by the English.  This prelate—­whether he was moved by the generosity of his nature and his affection to public good or had entertained an animosity against John, on account of the long opposition made by that prince to his election, or thought that an acquisition of liberty to the people would serve to increase and secure the privileges of the Church—­had formed the plan of reforming the government.  In a private meeting of some principal barons at London, he showed them a copy of Henry I’s charter, which, he said, he had happily found in a monastery; and he exhorted them to insist on the renewal and observance of it.  The barons swore that they would sooner lose their lives than depart from so reasonable a demand.

The confederacy began now to spread wider, and to comprehend almost all the barons in England; and a new and more numerous meeting was summoned by Langton at St. Edmundsbury, under color of devotion.  He again produced to the assembly the old charter of Henry; renewed his exhortations of unanimity and vigor in the prosecution of their purpose; and represented, in the strongest colors, the tyranny to which they had so long been subjected, and from which it now behooved them to free themselves and their posterity.  The barons, inflamed by his eloquence, incited by the sense of their own wrongs, and encouraged by the appearance of their power and numbers, solemnly took an oath, before the high altar, to adhere to each other, to insist on their demands, and to make endless war on the King till he should submit to grant them.  They agreed that, after the festival of Christmas, they would prefer in a body their common petition; and in the mean time they separated, after mutually engaging that they would put themselves in a posture of defence, would enlist men and purchase arms, and would supply their castles with the necessary provisions.

The barons appeared in London on the day appointed, and demanded of the King, that, in consequence of his own oath before the primate, as well as in deference to their just rights, he should grant them a renewal of Henry’s charter, and a confirmation of the laws of St. Edward.  The King, alarmed with their zeal and unanimity, as well as with their power, required a delay; promised that, at the festival of Easter, he would give them a positive answer to their petition; and offered them the Archbishop of Canterbury, the Bishop of Ely, and the Earl of Pembroke as sureties for his fulfilling this engagement.  The barons accepted of the terms, and peaceably returned to their castles.
