138 The Period of Constitution Making ciality, the falseness of any scheme of arrangement, logical or chronological. But he must either not write at all or choose an untrue scheme and trust to cross-references and the intelligence of the reader. There is some justifi- cation in taking the courts first, for so much was done in the twelfth century in developing the king's court and founding the common law, though much was left for the thirteenth and even later centuries.1 The great, non- specialised power of king and Council, interpenetrating both courts and Parliament, will be treated next, and in that connection the organs of administration through which central executive authority operated, and the all- important governmental work of the people in the locali- ties under the king's command. But the barons fought to control the king and Council, using and developing the principle of the supremacy of the law*f and the barons often believed and often made others believe that they spoke for the nation. Thus the examination of a new, extra-royal source of authority enters here and the begin- nings of limited monarchy. Parliament, dealt with third, was becoming recognisable as such by the early fourteenth century; and Parliament—made by the king and used by him for his own purposes and, like most early features of government, largely judicial in its work—had, before the close of our period, shown that it could upon occasion draw to an issue with the king and embody an authority outside him, and also that its future lay in the field of legislation. 1" Of all centuries the twelfth is the most legal. In no other age, since the classical days of the Roman law, has so large a part of the sum total of intellectual endeavour been devoted to jurisprudence."—P. and M. i., iii. "In the natural course of all constitutional history the judicial precedes the legislative."—Shirley, Preface to Royal Letters [Rolls Series] ii, p. xviii.
