In 917, after Li K'o-yung's death, the Sha-t'o Turks beat off an attack from the Kitan, and so were safe for a time from the northern menace. They then marched against the Liang state, where a crisis had been produced in 912 after the murder of Chu Ch'üan-chung by one of his sons. The Liang generals saw no reason why they should fight for the dynasty, and all of them went over to the enemy. Thus the "Later T'ang dynasty" (923-936) came into power in North China, under the son of Li K'o-yung. The dominant element at this time was quite clearly the Chinese gentry, especially in western and central China. The Sha-t'o themselves must have been extraordinarily few in number, probably little more than 100,000 men. Most of them, moreover, were politically passive, being simple soldiers. Only the ruling family and its following played any active part, together with a few families related to it by marriage. The whole state was regarded by the Sha-t'o rulers as a sort of family enterprise, members of the family being placed in the most important positions. As there were not enough of them, they adopted into the family large numbers of aliens of all nationalities. Military posts were given to faithful members of Li K'o-yung's or his successor's bodyguard, and also to domestic servants and other clients of the family. Thus, while in the Later Liang state elements from the peasantry had risen in the world, some of these neo-gentry reaching the top of the social pyramid in the centuries that followed, in the Sha-t'o state some of its warriors, drawn from the most various peoples, entered the gentry class through their personal relations with the ruler. But in spite of all this the bulk of the officials came once more from the Chinese. These educated Chinese not only succeeded in winning over the rulers themselves to the Chinese cultural ideal, but persuaded them to adopt laws that substantially restricted the privileges of the Sha-t'o and brought advantages only to the Chinese gentry. Consequently all the Chinese historians are enthusiastic about the "Later T'ang", and especially about the emperor Ming Ti, who reigned from 927 onward, after the assassination of his predecessor. They also abused the Liang because they were against the gentry.
