270 The Period of Constitution Making without the consent of the vassals. They did not mean to deny the principle of scutage or say that consent was necessary to normal commutation of bona fide feudal service; later dealings between king and barons make this plain. What they did mean was that John's per- versions of scutage must be brought under control and that no "gracious aid/' i.e. an aid beyond the three allowed in feudal custom, should be taken without con- sent. That the "common counsel" referred to was simply that which the king found in Ms feudal court is made certain by the detailed description, in article four- teen, of how such counsel was to be taken.x But in the period following the Charter, feudal ideas and practices were rapidly disappearing; taxation developed along several lines; the Charter, though, with this, among other articles, omitted, was frequently confirmed, and the contract idea running throughout it was thus kept alive—and that in a period when people were not scien- tific in their use of history and did not enquire what the contract covered or meant at an earlier time. The result was that, whereas in 1215, in this matter of aids and scutages, the king's vassals held him to the feudal law, at the end of the century the nobles, assuming to speak for the nation, said that the king should not levy taxes without general consent. A completer illustration is found in article sixty-one. This article sets forth the contract principle in more general terms. It says, in effect, that there were recog- nised customs and laws, such as those just set down, which the king was bound to keep, and that if he did not his people could compel him to keep them; and it pro- vided the clumsy machinery of the twenty-five barons to this end. Feudalism was clearly the source of this idea. The feudal contract was the formal ground for this whole baronial movement, that which saved it from 1 For a discussion of the famous phrase commune consitium, especially as to whether or not it was an assembly name, see American Historical 9 xxv., 1-17.
