14. =The 'Confirmatio Cartarum.' 1297.=--In =1297= Edward, having subdued the Scots in the preceding year, resolved to conduct one army to Flanders, and to send another to Gascony to maintain his rights against Philip IV. He therefore called on his barons to take part in these enterprises. Amongst those ordered to go to Gascony were Roger Bigod, Earl of Norfolk, and Humfrey Bohun, Earl of Hereford. They declared that they were only bound to follow the king himself, and that as Edward was not going in person to Gascony they would not go. "By God, Sir Earl," said the king to one of them, "you shall either go or hang." "By God," was the reply, "I will neither go nor hang." The two earls soon found support. The barons were sore because Edward's reforms had diminished their authority. The clergy were sore because of their recent treatment. The merchants were sore because of the exactions to which they had been subjected. Archbishop Winchelsey bound the malcontents together by asking Edward to confirm _Magna Carta_ and other charters granted by his predecessors, and by adding other articles now proposed for the first time, so as to preclude him from demanding taxes not granted by Parliament. Edward found that the new articles restricted his action more than it had been restricted by the older charters. He was deeply vexed, as he thought that he deserved to be trusted, and that, though he had exacted illegal payments, he had only done so out of necessity. He saw, however, that he must yield, but he could not bring himself to yield in person, and he therefore crossed the sea to Flanders, leaving the Prince of Wales to make the required concession. On October 10, =1297=, the _Confirmatio Cartarum_, as it was called, was issued in the king's name. It differed from _Magna Carta_ in this, that whereas John had only engaged not to exact feudal revenue from his vassals without consent of Parliament, Edward I. also engaged not to exact customs duties without a Parliamentary grant. From that time no general revenue could be taken from the whole realm without a breach of the law, though the king still continued for some time to raise tallages, or special payments, from the tenants of his own demesne lands.
