For more than two centuries the Ashikaga lorded it over Japan, as the Hojo had done before them, and the mikados were tools in their strong hands. Then arose a man who overthrew this powerful clan. This man, Nobunaga by name, was a descendant of Kiyomori, the great leader of the Taira clan, his direct ancestor being one of the few who escaped from the great Minamoto massacre. The father of this Taira chief was a soldier whose valor had won him a large estate. Nobunaga added to it, built himself a strong castle, and became the friend and patron of the last of the Ashikaga, whom he made shogun. (The Ashikaga were descendants of the Minamoto, who alone had hereditary claim to this high office.) But Nobunaga remained the power behind the throne, and, a quarrel arising between him and the shogun, he deposed the latter, and became himself the ruler of Japan. After two hundred and thirty-eight years of dominion the lordship of the Ashikaga thus came to an end. Of this great Japanese leader we are told, "He was a prince of large stature, but of weak and delicate complexion, with a heart and soul that supplied all other wants; ambitious above all mankind; brave, generous, and bold, and not without many excellent moral virtues; inclined to justice, and an enemy to treason. With a quick and penetrating wit, he seemed cut out for business. Excelling in military discipline, he was esteemed the fittest to command an army, manage a siege, fortify a town, or mark out a camp of any general in Japan, never using any head but his own. If he asked advice, it was more to know their hearts than to profit by their advice. He sought to see into others and to conceal his own counsel, being very secret in his designs. He laughed at the worship of the gods, being convinced that the bonzes were impostors abusing the simplicity of the people and screening their own debauches under the name of religion." Such was the man who by genius and strength of will now rose to the head of affairs. Not being of the Minamoto family, he did not seek to make himself shogun, and for forty years this office ceased to exist. He ruled in the name of the mikado, but held all the power of the realm. The good fortune of Nobunaga lay largely in his wise choice of men. Under him were four generals, so admirable yet so diverse in military ability that the people gave them the distinctive nicknames of "Cotton," "Rice," "Attack," and "Retreat." Cotton, which can be put to a multitude of uses, indicated the fertility in resources of the first; while the second made himself as necessary as rice, which people cannot live a day without. The strength of the third lay in the boldness of his attacks; of the fourth, in the skill of his retreats. Of these four, the first, named Hideyoshi, rose to great fame. A fifth was afterwards added, Tokugawa Iyeyasu, also a famous name in Japan.
