The king was strong enough to face and imprison the warring earls, to hang the chiefs of the Boston marauders, and to suppress the outlaws by rigorous commissions. But the repression of baronial outrage was only a part of Edward's policy in relation to the Baronage. Here, as elsewhere, he had to carry out the political policy of his house, a policy defined by the great measures of Henry the Second, his institution of scutage, his general assize of arms, his extension of the itinerant judicature of the royal judges. Forced by the first to an exact discharge of their military duties to the Crown, set by the second in the midst of a people trained equally with the nobles to arms, their judicial tyranny curbed and subjected to the king's justice by the third, the barons had been forced from their old standpoint of an isolated class to the new and nobler position of a people's leaders. Edward watched jealously over the ground which the Crown had gained. Immediately after his landing he appointed a commission of enquiry into the judicial franchises then existing, and on its report (of which the existing "Hundred-Rolls" are the result) itinerant justices were sent in 1278 to discover by what right these franchises were held. The writs of "quo warranto" were roughly met here and there. Earl Warenne bared a rusty sword and flung it on the justices' table. "This, sirs," he said, "is my warrant. By the sword our fathers won their lands when they came over with the Conqueror, and by the sword we will keep them." But the king was far from limiting himself to the mere carrying out of the plans of Henry the Second. Henry had aimed simply at lowering the power of the great feudatories; Edward aimed rather at neutralizing their power by raising the whole body of landowners to the same level. We shall see at a later time the measures which were the issues of this policy, but in the very opening of his reign a significant step pointed to the king's drift. In the summer of 1278 a royal writ ordered all freeholders who held lands to the value of twenty pounds to receive knighthood at the king's hands.
Acts as significant announced Edward's purpose of carrying out another side of Henry's policy, that of limiting in the same way the independent jurisdiction of the Church. He was resolute to force it to become thoroughly national by bearing its due part of the common national burthens, and to break its growing dependence upon Rome. But the ecclesiastical body was jealous of its position as a power distinct from the power of the Crown, and Edward's policy had hardly declared itself when in 1279 Archbishop Peckham obtained a canon from the clergy by which copies of the Great Charter, with its provisions in favour of the liberties of the Church, were to be affixed to the doors of churches. The step was meant as a defiant protest against all interference, and it was promptly forbidden. An order issued by the Primate to the clergy to declare to their flocks the sentences of excommunication directed against all who obtained royal writs to obstruct suits in church courts, or who, whether royal officers or no, neglected to enforce their sentences, was answered in a yet more emphatic way. By falling into the "dead hand" or "mortmain" of the Church land ceased to render its feudal services; and in 1279 the Statute "de Religiosis," or as it is commonly called "of Mortmain," forbade any further alienation of land to religious bodies in such wise that it should cease to render its due service to the king. The restriction was probably no beneficial one to the country at large, for Churchmen were the best landlords, and it was soon evaded by the ingenuity of the clerical lawyers; but it marked the growing jealousy of any attempt to set aside what was national from serving the general need and profit of the nation. Its immediate effect was to stir the clergy to a bitter resentment. But Edward remained firm, and when the bishops proposed to restrict the royal courts from dealing with cases of patronage or causes which touched the chattels of Churchmen he met their proposals by an instant prohibition.
