Before discussing the origins or the effects of feudalism it is well to form a definite conception of the system as we find it in the twelfth and thirteenth centuries, when it is the basis of local government, of justice, of legislation, of the army and of all executive power. In this period the lawyers have arrived at the doctrine that all lands is held from the King either mediately or directly. The King is himself a great landowner with demesnes scattered over the length and breadth of the realm; the revenues of these estates supply him with the larger part of his permanent income.
