The political authority over the whole nation was held by the feudal government. The feudal system was first established by Minamoto no Yoritomo towards the close of the twelfth century; at first there was no intention of replacing the Imperial Court in the government of the country; but from various causes the political and military power fell into the Shogun’s hands. The Emperor merely watched over the sacred treasures of his House and delegated political power to the feudal government. During the civil wars the fortunes of Imperial Court seriously declined; but Ota and Toyotomi, who were loyal to the Throne, presented landed estate to the Court when they had brought the country into peace. Tokugawa frequently built Imperial palaces and presented funds for household expenses; and the Imperial House was placed in easier circumstances. But it was the policy of the Tokugawa family to hold the real power over the nation. In 1614, Iyeyasu established regulations for the control of the _kuge_, by which although the real power of the Imperial House was diminished the principle of loyalty to the Throne and distinction of lord and subject were strictly maintained, and Tokugawa himself set the example to the nation by his reverent treatment of the Imperial Family. Although this attitude towards the Throne was a policy of Iyeyasu, it was also an expression of the innate loyalty and patriotism of the people. Thus, the dignity of the Imperial Family remained unimpaired; and it may be seen from the original cause of the Ako revenge how high the importance was attached to the reception of Imperial envoys. THE SAMURAI. The samurai were all under the control of the feudal government. Those whose annual stipends were not less than ten thousand _koku_ of rice were called _daimyo_, those below them were _hatamoto_, and the lowest were _kenin_. The _daimyo_ were of three classes, lords of provinces, lords of castles, and lords of domains without castles. They ruled over their domains. Asano Takumi-no-Kami, the vengeance for whose death forms the subject of the _Chushingura_, was the lord of the castle of Ako in the province of Harima; his annual income was 50,000 _koku_; he belonged to the second category of _daimyo_. The _daimyo_ came in turn to Yedo for a short stay; and among their retainers, some remained permanently in Yedo, while others accompanied their lords on their journeys to and from the Shogun’s city. The samurai who left their clans and drifted about, or for some reason, lost their stipends, were known as _ronin_. Such were the retainers of Ako who lost their stipends through the fall of their lord’s house. THE COMMON PEOPLE. By common people were meant the merchant and agricultural classes. They were not permitted to wear swords or have family names; and they were known only by their individual names. Thus, merchants and artisans were called by their trades and farmers by their villages.
