It was Ts'i that drove back the Mongol-Manchu tribes and rescued Yen in 662; it was the Ts'i ruler who led a coalition of princes against other groups of Tartars and placed back on his ancestral throne the ruler of Wei, who had been driven from his country by Tartars in 658; it was the First Protector, ruler of Ts'i, who managed to pacify the more westerly Tartars we find persistently menacing the Emperor in 648; to whose rescue the Tartars came in 642, when a coalition of orthodox Chinese princes shamelessly took advantage of the First Protector's death to attack Ts'i during the mourning period. Now it was that the Second Protector, still a refugee among his Tartar relatives, started for Ts'i, his original idea being to replace the philosopher Kwan-tsz as adviser to the First Protector; but, shortly after he reached Ts'i, the First Protector died, and it was only by stratagem that his friends succeeded in rescuing the future Second Protector from the arms of his Ts'i Delilah and his _d'elices de_ Capue. His chief adviser, and at the same time his brother-in-law from a Tartar point of view, was the lineal descendant of the Chao man who had saved the Emperor in 800 B.C. He set out, _via_ the orthodox states, for his own country. These petty orthodox states, such as Wei, Cheng, and Ts'ao, which did not then see their way to profit politically by the Pretender's visit, paid the penalty of their meanness and their rudeness to him later on. Sung was polite, as at that time Sung and Ts'u were both aiming at the Protectorship. Ts'u's hospitality was bluff and good-natured, the King being too strong to fear, and too unsophisticated to intrigue after Chinese fashion. Just then news coming from Ts'in that the Pretender's brothers had all resigned or died, and that his chance had now come, the Pretender hurried to Tsin, regained his throne, and was acclaimed Protector of China exactly at the critical moment when a strong hand was urgently required to check the particular ambitions of Ts'in, Ts'i, and Ts'u. Ts'u was too barbarous; Sung was too pedantic; Tsin alone had unrivalled experience both of Tartars and Eastern barbarians, and also of Southern barbarians (Ts'u). Probably it was only the fact of the Tsin ruling family bearing the same clan-name as the Emperor that had decided Tsin throughout to be orthodox Chinese instead of Tartar. The Tartar family into which the Second Protector had married as a comparatively young man was, however, also of the imperial clan- name, i.e. it was of orthodox Chinese origin, but (even like the Chou imperial family at one time) it had adopted Tartar customs. A large number of the one thousand or more petty Chinese principalities, attached not directly to the Emperor, but to the greater vassals as mesne lords, were in the same predicament; that is to say, they were of Chinese origin, but they had found that it paid them best to adopt barbarian ways. It was exactly as though Scipio
