The earliest Japanese society was not, therefore, even a feudalism in the meaning which we commonly attach to that word: it was a union of clans at first combined for defence and offence,--each clan having a religion of its own. Gradually one clan-group, by power of wealth and numbers, obtained such domination that it was able to impose its cult upon all the rest, and to make its hereditary chief Supreme High Pontiff. The worship of the Sun-goddess so became a race-cult; but this worship did not diminish the relative importance of the other clan-cults,--it only furnished them with a common tradition. Eventually a nation formed; but the clan remained the real unit of society; and not until the present era of Meiji was its disintegration effected--at least in so far as legislation could accomplish. [239] We may call that period during which the clans became really united under one head, and the national cult was established, the First Period of Japanese Social Evolution. However, the social organism did not develop to the limit of its type until the era of the Tokugawa shoguns,--so that, in order to study it as a completed structure, we must turn to modern times. Yet it had taken on the vague outline of its destined form as early as the reign of the Emperor Temmu, whose accession is generally dated 673 A.D. During that reign Buddhism appears to have become a powerful influence at court; for the Emperor practically imposed a vegetarian diet upon the people--proof positive of supreme power in fact as well as in theory. Even before this time society had been arranged into ranks and grades,--each of the upper grades being distinguished by the form and quality of the official head-dresses worn; but the Emperor Temmu established many new grades, and reorganized the whole administration, after the Chinese manner, in one hundred and eight departments. Japanese society then assumed, as to its upper ranks, nearly all the hierarchical forms which it presented down to the era of the Tokugawa shoguns, who consolidated the system without seriously changing its fundamental structure. We may say that from the close of the First Period of its social evolution, the nation remained practically separated into two classes: the [240] governing class, including all orders of the nobility and military; and the producing class, comprising all the rest. The chief event of the Second Period of the social evolution was the rise of the military power, which left the imperial religious authority intact, but usurped all the administrative functions (this subject will be considered in a later chapter). The society eventually crystallized by this military power was a very complex structure--outwardly resembling a huge feudalism, as we understand the term, but intrinsically different from any European feudalism that ever existed. The difference lay especially in the religious organization of the Japanese communities, each of which, retaining its particular
