226 The Period ot Constitution MaJang popular usage and custom, in contradistinction to statute law. (c) More narrowly that part of the system just defined which was recognised and administered by the king's justices In contradistinction to the modifications introduced by the chancellors as rules of equity in restraint or enlargement of the customary and statutory law.1 Beside this, may be placed the history of the term. Com- mon law first meant a law that was common to all Eng- land, a law not for this or that county or borough. It was thus used in the twelfth and thirteenth centuries. It was next used in opposition to statute law, as the latter developed during the fourteenth century; then, in opposi- tion to equity when the Court of Chancery became im- portant in the fifteen century. By that time, the concep- tion of it as a body of law older than, and in important ways distinguished from, two other bodies of law had crowded out the original meaning of common. The first of the present usages, just cited, seems to have come from applying to the whole of England's law the name of its most characteristic and historically important part. It is an untechnical use, but serves to distinguish England's law and legal history from those of other European coun- tries. Had no system of king's courts grown after the Norman Conquest, the Anglo-Saxon law, administered in the local courts, would, it is to be supposed, have continued to develop. It seems, from what is known of continental history, that from such a law, administered in courts so isolated from one another, no law common to the whole country could have grown. Without the common courts, there could not have been the common law. Rather, the differences, which existed among the localities when condi- tions were primitive and the people fairly homogeneous, would have become ever greater.
