Nobunaga's removal at once made Hideyoshi the most conspicuous figure in the empire, the only man with any claim to dispute that title being Tokugawa Iyeyasu. These two had hitherto worked in concert. But the question of the succession to Nobunaga's estates threw the country once more into tumult. He left two grown-up sons and a baby grandson, whose father, Nobunaga's first-born, had perished in the holocaust at Honno-ji. Hideyoshi, not unmindful, it may be assumed, of the privileges of a guardian, espoused the cause of the infant, and wrested from Nobunaga's three other great captains a reluctant endorsement of his choice. Nobutaka, third son of Nobunaga, at once drew the sword, which he presently had to turn against his own person; two years later (1584), his elder brother, Nobuo, took the field under the aegis of Tokugawa Iyeyasu. Hideyoshi and Iyeyasu, now pitted against each other for the first time, were found to be of equal prowess, and being too wise to prolong a useless war, they reverted to their old alliance, subsequently confirming it by a family union, the son of Iyeyasu being adopted by Hideyoshi and the latter's daughter being given in marriage to Iyeyasu. Hideyoshi had now been invested by the mikado with the post of regent, and his position in the capital was omnipotent. He organized in Kioto a magnificent pageant, in which the principal figures were himself, Iyeyasu, Nobuo and twenty-seven daimyos. The emperor was present. Hideyoshi sat on the right of the throne, and all the nobles did obeisance to the sovereign. Prior to this event Hideyoshi had conducted against the still defiant daimyos of Kiushiu, especially Shimazu of Satsuma, the greatest army ever massed by any Japanese general, and had reduced the island of the nine provinces, not by weight of armament only, but also by a signal exercise of the wise clemency which distinguished him from all the statesmen of his era.
