During the 260 years of alien rule in North China, the picture of South China also was full of change. When in 317 the Huns had destroyed the Chinese Chin dynasty in the north, a Chin prince who normally would not have become heir to the throne declared himself, under the name Yüan Ti, the first emperor of the "Eastern Chin dynasty" (317-419). The capital of this new southern empire adjoined the present Nanking. Countless members of the Chinese gentry had fled from the Huns at that time and had come into the southern empire. They had not done so out of loyalty to the Chinese dynasty or out of national feeling, but because they saw little prospect of attaining rank and influence at the courts of the alien rulers, and because it was to be feared that the aliens would turn the fields into pasturage, and also that they would make an end of the economic and monetary system which the gentry had evolved for their own benefit. But the south was, of course, not uninhabited. There were already two groups living there--the old autochthonous population, consisting of Yao, Tai and Yüeh, and the earlier Chinese immigrants from the north, who had mainly arrived in the time of the Three Kingdoms, at the beginning of the third century A.D. The countless new immigrants now came into sharp conflict with the old-established earlier immigrants. Each group looked down on the other and abused it. The two immigrant groups in particular not only spoke different dialects but had developed differently in respect to manners and customs. A look for example at Formosa in the years after 1948 will certainly help in an understanding of this situation: analogous tensions developed between the new refugees, the old Chinese immigrants, and the native Formosan population. But let us return to the southern empires.
