For this there were several reasons. A nomad people was again ruling the agrarian regions of North China. This time the representatives of the ruling class remained military commanders, and at the same time retained their herds of horses. As early as 1100 they had well over 10,000 herds, each of more than a thousand animals. The army commanders had been awarded large regions which they themselves had conquered. They collected the taxes in these regions, and passed on to the state only the yield of the wine tax. On the other hand, in order to feed the armies, in which there were now many Chinese soldiers, the frontier regions were settled, the soldiers working as peasants in times of peace, and peasants being required to contribute to the support of the army. Both processes increased the interest of the Kitan ruling class in the maintenance of peace. That class was growing rich, and preferred living on the income from its properties or settlements to going to war, which had become a more and more serious matter after the founding of the great Sung empire, and was bound to be less remunerative. The herds of horses were a further excellent source of income, for they could be sold to the Sung, who had no horses. Then, from 1004 onward, came the tribute payments from China, strengthening the interest in the maintenance of peace. Thus great wealth accumulated in Peking, the capital of the Liao; in this wealth the whole Kitan ruling class participated, but the tribes in the north, owing to their remoteness, had no share in it. In 988 the Chinese began negotiations, as a move in their diplomacy, with the ruler of the later realm of the Hsia; in 990 the Kitan also negotiated with him, and they soon became a third partner in the diplomatic game. Delegations were continually going from one to another of the three realms, and they were joined by trade missions. Agreement was soon reached on frontier questions, on armament, on questions of demobilization, on the demilitarization of particular regions, and so on, for the last thing anyone wanted was to fight.

Then came the rising of the tribes of the north. They had remained military tribes; of all the wealth nothing reached them, and they were given no military employment, so that they had no hope of improving their position. The leadership was assumed by the tribe of the Juchên (1114). In a campaign of unprecedented rapidity they captured Peking, and the Liao dynasty was ended (1125), a year earlier, as we know, than the end of the Sung.

2 The State of the Kara-Kitai

A small troop of Liao, under the command of a member of the ruling family, fled into the west. They were pursued without cessation, but they succeeded in fighting their way through. After a few years of nomad life in the mountains of northern Turkestan, they were able to gain the collaboration of a few more tribes, and with them they then invaded western Turkestan. There they founded the "Western Liao" state, or, as the western sources call it, the "Kara-Kitai" state, with its capital at Balasagun. This state must not be regarded as a purely Kitan state. The Kitan formed only a very thin stratum, and the real power was in the hands of autochthonous Turkish tribes, to whom the Kitan soon became entirely assimilated in culture. Thus the history of this state belongs to that of western Asia, especially as the relations of the Kara-Kitai with the Far East were entirely broken off. In 1211 the state was finally destroyed.

1 Continuation of Turkish traditions

After the end of the Toba state in North China in 550, some tribes of the Toba, including members of the ruling tribe with the tribal name Toba, withdrew to the borderland between Tibet and China, where they ruled over Tibetan and Tangut tribes. At the beginning of the T'ang dynasty this tribe of Toba joined the T'ang. The tribal leader received in return, as a distinction, the family name of the T'ang dynasty, Li. His dependence on China was, however, only nominal and soon came entirely to an end. In the tenth century the tribe gained in strength. It is typical of the long continuance of old tribal traditions that a leader of the tribe in the tenth century married a woman belonging to the family to which the khans of the Hsiung-nu and all Turkish ruling houses had belonged since 200 B.C. With the rise of the Kitan in the north and of the Tibetan state in the south, the tribe decided to seek the friendship of China. Its first mission, in 982, was well received. Presents were sent to the chieftain of the tribe, he was helped against his enemies, and he was given the status of a feudatory of the Sung; in 988 the family name of the Sung, Chao, was conferred on him. Then the Kitan took a hand. They over-trumped the Sung by proclaiming the tribal chieftain king of Hsia (990). Now the small state became interesting. It was pampered by Liao and Sung in the effort to win it over or to keep its friendship. The state grew; in 1031 its ruler resumed the old family name of the Toba, thus proclaiming his intention to continue the Toba empire; in 1034 he definitely parted from the Sung, and in 1038 he proclaimed himself emperor in the Hsia dynasty, or, as the Chinese generally called it, the "Hsi-Hsia", which means the Western Hsia. This name, too, had associations with the old Hun tradition; it recalled the state of Ho-lien P'o-p'o in the early fifth century. The state soon covered the present province of Kansu, small parts of the adjoining Tibetan territory, and parts of the Ordos region. It attacked the province of Shensi, but the Chinese and the Liao attached the greatest importance to that territory. Thus that was the scene of most of the fighting.

The language of the country was Tibetan; the customs were those of the Tanguts. A script was devised, in imitation of the Chinese script. Only in recent years has it begun to be studied.

In 1125, when the Tungusic Juchên destroyed the Liao, the Hsia also lost large territories in the east of their country, especially the province of Shensi, which they had conquered; but they were still able to hold their own. Their political importance to China, however, vanished, since they were now divided from southern China and as partners were no longer of the same value to it. Not until the Mongols became a power did the Hsia recover some of their importance; but they were among the first victims of the Mongols: in 1209 they had to submit to them, and in 1227, the year of the death of Genghiz Khan, they were annihilated.
