It is necessary to leave for a time the English monarchy at its zenith, still enjoying in 1189 the powers and reputation gained for it by Henry of Anjou, and to retrace our steps, in order to consider two subsidiary problems, each of which requires separate treatment—the problem of local government, and that of the relations between Church and State. The failure of the Princes of the House of Wessex to devise adequate machinery for keeping the Danish and Anglian provinces in subjection to their will was one main source of the weakness of their monarchy. When Duke William solved this problem he took an enormous stride towards establishing his throne on a securer basis. Every age has to face, in its own way, a group of difficulties essentially the same, although assuming such different names as Home Rule, Local Government, or Federation. Problems as to the proper nature of the local authority, the extent of the powers with which it may be safely entrusted, and its relation to the central government, require constantly to be solved. The difficulties involved, always great, were unspeakably greater in an age when practically no administrative machinery existed, and when rapid communication and serviceable roads were unknown. A lively sympathy is excited by a consideration of the almost insuperable difficulties that beset the path of King Edgar or King Ethelred, endeavouring to rule from Winchester the distant tribes of alien races inhabiting Northumbria, Mercia, and East Anglia. If such a king placed a weakling as ruler over any distant province, anarchy would result and his own authority might be endangered along with that of his inefficient representative. Yet, if he entrusted the rule of that province to too strong a man, he might find his suzerainty shaken off by a viceroy who had consolidated his position and then defied his king. Here, then, are the two horns of a dilemma, both of which are illustrated by the course of early English history. When Wessex had established some measure of authority over rival states, and was fast growing into England, the policy at first followed was simply to leave each province under its old native line of rulers, who now admitted a nominal dependence on the King who ruled at Winchester. The early West-Saxon Princes vacillated between two opposite lines of policy. Spasmodic attempts at centralization alternated with the reverse policy of local autonomy. In the days when Dunstan united the spiritual duties of the See of Canterbury to the temporal duties of chief adviser to King Edgar, the problem of local government became urgent. Dunstan’s scheme has sometimes been described as a federal or home-rule policy—as a frank surrender of the attempt to control exclusively from one centre the mixed populations of Northern and Midland England. His attempted solution was to loosen rather than to tighten further the bond; to entrust with wide powers and franchises the local viceroy or ealdorman
