The evils of the day became specially revealed during the reign of Ytsong, who was scarcely seated on the throne before his troops suffered several defeats at the hands of a rebel prince in Yunnan, who completely wrested that province from the empire. He was as pronounced a patron of Buddhism as some of his predecessors had been oppressors, and he sent, at enormous expense, to India a mission to procure a bone of Buddha's body, and on its arrival he received the relic on bended knees before his whole court. His extravagance of living landed the Chinese government in fresh difficulties, and he brought the exchequer to the verge of bankruptcy. Nor was he a humane ruler. On one occasion he executed twenty doctors because they were unable to cure a favorite daughter of his. His son Hitsong came to the throne when he was a mere boy, and at once experienced the depth of misfortune to which his family had sunk. He was driven out of his capital by a rebel named Hwang Chao, and if he had not found an unexpected ally in the Turk chief Likeyong, there would then have been an end to the Tang dynasty. This chief of the Chato immigrants - a race supposed to be the ancestors of the Mohammedan Tungani of more recent times - at the head of forty thousand men of his own race, who, from the color of their uniform, were named "The Black Crows," marched against Hwang Chao, and signally defeated him. The condition of the country at this time is painted in deplorable colors. The emperor did not possess a palace, and all the great towns of Central China were in ruins. Likeyong took in the situation at a glance, when he said, "The ruin of the Tangs is not far distant." Likeyong, who was created Prince of Tsin, did his best to support the emperor, but his power was inadequate for coping with another general named Chuwen, prince of Leang, in whose hands the emperor became a mere puppet. At the safe moment Chuwen murdered his sovereign, and added to this crime a massacre of all the Tang princes upon whom he could lay his hands. Chao Siuenti, the last of the Tangs, abdicated, and a few months later Chuwen, to make assurance doubly sure, assassinated him. Thus disappeared, after two hundred and eighty-nine years and after giving twenty rulers to the state, the great Tang dynasty which had restored the unity and the fame of China. It forms a separate chapter in the long period of disunion from the fall of the Hans to the rise of the Sungs.

After the Tangs came five ephemeral and insignificant dynasties, with the fate of which we need not long detain the reader. In less than sixty years they all vanished from the page of history. The struggle for power between Chuwen, the founder of the so-called Later Leang dynasty, and Likeyong was successfully continued by the latter's son, Litsunhiu, who proved himself a good soldier. He won a decisive victory at Houlieoupi, and extinguished the Leang dynasty by the capture of its capital and of Chuwen's son, who committed suicide. Litsunhiu ruled for a short time as emperor of the Later Leangs, but he was killed during a mutiny of his turbulent soldiers. This dynasty had a very brief existence; the last ruler of the line, finding the game was up, retired with his family to a tower in his palace, which he set on fire, and perished, with his wives and children, in the flames. Then came the Later Tsins, who only held their authority on the sufferance of the powerful Khitan king, who reigned over Leaoutung and Manchuria. The fourth and fifth of these dynasties, named the Later Hans and Chows, ran their course in less than ten years; and when the last of these petty rulers was deposed by his prime minister a termination was at last reached to the long period of internal division and weakness which prevailed for more than seven hundred and fifty years. The student reaches at this point firmer ground in the history of China as an empire, and his interest in the subject must assume a more definite form on coming to the beginning of that period of united government and settled authority which has been established for nearly one thousand years, during which no more than four separate families have held possession of the throne.
