the Way of the Gods," must have given the priestly clan matter for serious reflection.... Besides, there is another important fact to be noticed. The Imperial household proper had become, in the course of centuries, entirely detached from the Uji; and the omnipotence of this unit, independent of all other units, constituted in itself a grave danger to aristocratic privileges and established institutions. Too much might depend upon the personal character and will of an omnipotent God-King, capable of breaking with all clan-custom, and of abrogating clan-privileges. On the other hand, there was safety for all alike under the patriarchal rule of the clan, which [266] could cheek every tendency on the part of any of its members to exert predominant influence at the expense of the rest. But for obvious reasons the Imperial cult--traditional source of all authority and privilege--could not be touched: it was only by maintaining and reinforcing it that the religious nobility could expect to keep the real power in their hands. They actually kept it for nearly five centuries. The history of all the Japanese regencies, however, amply illustrates the general rule that inherited authority is ever and everywhere liable to find itself supplanted by deputed authority. The Fujiwara appear to have eventually become the victims of that luxury which they had themselves, for reasons of policy, introduced and maintained. Degenerating into a mere court-nobility, they made little effort to exert any direct authority in other than civil directions, entrusting military matters almost wholly to the Buke. In the eighth century the distinction between military and civil organization had been made upon the Chinese plan; the great military class then came into existence, and began to extend its power rapidly. Of the military clans proper, the most powerful were the Minamoto and the Taira. By deputing to these clans the conduct of all important matters relating to war, the Fujiwara eventually lost their high position and influence. As soon [267] as the Buke found themselves strong enough to lay hands upon the reins of government,--which happened about the middle of the eleventh century,--the Fujiwara supremacy became a thing of the past, although members of the clan continued for centuries to occupy positions of importance under various regents. But the Buke could not realize their ambition without a bitter struggle among themselves,--the longest and the fiercest war in Japanese history. The Minamoto and the Taira were both Kuge; both claimed imperial descent. In the early part of the contest the Taira carried all before them; and it seemed that no power could hinder them from exterminating the rival clan. But fortune turned at last in favour of the Minamoto; and at the famous sea-fight of Dan-no-ura, in 1185, the Taira were themselves exterminated.
