xxxii Introduction a study of the long labour and suffering by which it has been wrought. The field of general English history is divided into the following main divisions1: a. Britain before the Roman occupation began, namely, before 55 B.C. This is practically prehistoric Britain. 6. Roman Britain, 55 B.c.-~4O7 A.D. c. England from the Anglo-Saxon conquest to the Norman Conquest, 449-1066. d. England from the Norman Conquest to the end of the middle ages, the period when governmental institu- tions were in the making, 1066-1485. e. The modern period, when through greater political self-consciousness these institutions were tested and de- veloped, and in recent times greatly modified and ex- tended. Constitutional history has nothing to do with the first division, and very little to do with the second, from which latter period little or nothing that is found in the later English government came. Our institutional story has its beginning in the third division, the Anglo-Saxon period. It is exceedingly important to note, however, that it had its beginning also on the continent. Through the Norman Conquest its roots run back through Norman history to France and the Prankish Empire, and draw from the soil of the whole continental development since the fall of Rome, and from Rome itself. Thus in its fullest sense English constitutional history did not begin until the Norman Conquest, because, until that time, there were not present in England all the materials out of which the constitution was to grow. There were, then, two great introductory lines of development, two tap roots from which the later constitution drew, the one Anglo-Saxon and the other Norman, the one largely insular, the other continental.2 The coming together of these through the 1 Strictly speaking, of course, there was no English history in the island of Britain until the coming of the Anglo-Saxons. 2 But It should be noted here, and the point will be illustrated in the account which follows, that Anglo-Saxon institutions owed much to con-
