If the element of continuity is thus important in the political system of Germany, France, or Switzerland, in that of England it is fundamental. It is not too much to say that the most striking aspect of English constitutional history is the continual preservation, in the teeth of inevitable changes, of a preponderating proportion of institutions that reach far into the past. "The great difficulty which presses on the student of the English constitution, regarded as a set of legal rules," observes a learned commentator, "is that he can never dissociate himself from history. There is hardly a rule which has not a long past, or which can be understood without some consideration of the circumstances under which it first came into being."[1] It is the purpose of the present volume to describe European governments as they to-day exist and operate. It will be necessary in all cases, however, to accord some consideration to the origins and growth of the political organs and practices which may be described. In respect to Great Britain this can mean nothing less than a survey, brief as may be, of a thousand years of history. [Footnote 1: W. R. Anson, The Law and Custom of the Constitution (3d ed., Oxford, 1897), I., 13.] II. ANGLO-SAXON BEGINNINGS The earliest form of the English constitution was that which existed during the centuries prior to the Norman Conquest. Political organization among the Germanic invaders of Britain was of the (p. 003) most rudimentary sort, but the circumstances of the conquest and settlement of the island were such as to stimulate a considerable elaboration of governmental machinery and powers. From the point of view of subsequent institutional history the most important features of the Anglo-Saxon governmental system were kingship, the witenagemot, and the units of local administration--shire, hundred, borough, and township.[2] [Footnote 2: See G. B. Adams, The Origin of the English Constitution (New Haven, 1912), Chap. 1. That the essentials of the English constitution of modern times, in respect to forms and machinery, are products of the feudalization of England which resulted from the Norman Conquest, and not survivals of Anglo-Saxon governmental arrangements, is the well-sustained thesis of this able study. That many important elements, however, were contributed by Anglo-Saxon statecraft is beyond dispute.]
