would be likely to seem to them possible,--the relationship of vassal and lord; and that with these first grants of land which the king made to his followers was introduced into England that side of the feudal system which Saxon England had never known, but which was, from this time on, for nearly two centuries, to be the ruling system in both public and private law. In saying that the feudal system was introduced into England by these grants, we must guard against a misconception. The feudal system, if we use that name as we commonly do to cover the entire relations of the society of that age, had two sides to it, distinct in origin, character, and purpose. To any clear understanding of the organization of feudal society, or of the change which its establishment made in English history, it is necessary, although it is not easy, to hold these two sides apart. There was in the practices and in the vocabulary of feudalism itself some confusion of the two in the borderland that lay between them, and the difficulty is made greater for us by the fact that both sides were primarily concerned with the holding of land, and especially by the fact that the same piece of land belonged at once to both sides and was held at the same time by two different men, by two different kinds of tenure, and under two different systems of law. The one side may be called from its ruling purpose economic and the other political. The one had for its object the income to be drawn from the land; the other regarded chiefly the political obligations joined to the land and the political or social rank and duties of the holders.
