Before treating, however, of the Genroku age in which the vendetta of the Ako retainers took place, which has left such a mark upon the history of this country, we must glance at the period of the Tokuwaga Shogunate. That period lasted two hundred and sixty-four years from the appointment to the Shogunate of Tokugawa Iyeyasu in 1603 to the surrender of political power to the Emperor by Tokugawa Yoshinobu in 1867. Towards the close of the Ashikaga Shogunate (1338-1573), the country was torn by factions and plunged in civil war. But the great hero Toyotomi Hideyoshi, better known as the Taiko, gave the country a brief respite from war. The predominance of his house, however, lasted only for two generations; and on the defeat of his son by Iyeyasu in 1600 at Sekigahara, supreme power fell into Iyeyasu’s hands, and the campaigns of Osaka in 1614 and 1615 put an end to the Toyotomi line. The nation now bowed to Iyeyasu’s authority, and his house ruled over it for more than two centuries and a half. THE IMPERIAL COURT. Society during the Tokugawa period may be generally divided into four classes, the _kuge_, the samurai, the common people, and the lowest classes. The Emperor reigned over the country at Kyoto; and around him were the Imperial princes, some of whom were qualified to succeed to the Throne in case of failure of Imperial issue. The _kuge_, or Court nobles, numbered about one hundred and thirty; their titles and offices were hereditary. They were jealous of their social position. They attended daily at the Imperial Court; but their duties mostly concerned the grant and deprivation of Court rank, various ceremonies, and Court etiquette. Administrative affairs were entirely in the hands of the feudal government. All business between it and the Imperial Court was transacted by a few high officials.
