_Early Historical Period._--With the emperor Richu, who came to the throne A.D. 400, the historical period may be said to commence; for though the chronology of the records is still questionable, the facts are generally accepted as credible. Conspicuous loyalty towards the sovereign was not an attribute of the Japanese Imperial family in early times. Attempts to usurp the throne were not uncommon, though there are very few instances of such essays on the part of a subject. Love or lust played no insignificant part in the drama, and a common method of placating an irate sovereign was to present a beautiful damsel for his delectation. The veto of consanguinity did not receive very strict respect in these matters. Children of the same father might intermarry, but not those of the same mother; a canon which becomes explicable on observing that as wives usually lived apart from their husbands and had the sole custody of their offspring, two or more families often remained to the end unconscious of the fact that they had a common sire. There was a remarkable tendency to organize the nation into groups of persons following the same pursuit or charged with the same functions. A group thus composed was called _be_. The heads of the great families had titles--as _omi_, _muraji_, _miakko_, _wake_, &c.--and affairs of state were administered by the most renowned of these nobles, wholly subject to the sovereign's ultimate will. The provincial districts were ruled by scions of the Imperial family, who appear to have been, on the whole, entirely subservient to the Throne. There were no tribunals of justice: the ordeal of boiling water or heated metal was the sole test of guilt or innocence, apart, of course, from confession, which was often exacted under menace of torture. A celebrated instance of the ordeal of boiling water is recorded in 415, when this device was employed to correct the genealogies of families suspected of falsely claiming descent from emperors or divine beings. The test proved efficacious, for men conscious of forgery refused to undergo the ordeal. Deprivation of rank was the lightest form of punishment; death the commonest, and occasionally the whole family of an offender became serfs of the house against which the offence had been committed or which had been instrumental in disclosing a crime. There are, however, frequent examples of wrong-doing expiated by the voluntary surrender of lands or other property. We find several instances of that extreme type of loyalty which became habitual in later ages--suicide in preference to surviving a deceased lord. On the whole the successive sovereigns of these early times appear to have ruled with clemency and consideration for the people's welfare. But there were two notable exceptions--Yuriaku (457-479) and Muretsu (499-506). The former slew men ruthlessly in fits of passion or resentment, and the latter was the Nero of Japanese history, a man who loved to witness the agony of his fellows and knew no sentiment of mercy or remorse. Yet even Yuriaku did not fail to promote industrial pursuits. Skilled artisans were obtained from Korea, and it is related that, in 462, this monarch induced the empress and the ladies of the palace to plant mulberry trees with their own hands in order to encourage sericulture. Throughout the 5th and 6th centuries many instances are recorded of the acquisition of landed estates by the Throne, and their occasional bestowal upon princes or Imperial consorts, such gifts being frequently accompanied by the assignment of bodies of agriculturists who seem to have accepted the position of serfs. Meanwhile Chinese civilization was gradually becoming known, either by direct contact or through Korea. Several immigrations of Chinese or Korean settlers are on record. No less than 7053 householders of Chinese subjects came, through Korea, in 540, and one of their number received high rank together with the post of director of the Imperial treasury. From these facts, and from a national register showing the derivation of all the principal families in Japan, it is clearly established that a considerable strain of Chinese and Korean blood runs in the veins of many Japanese subjects.
