The Yuchi aro believed to have been of a northern race, who bet:tune known in the west as Indo-Seythians, and at a later date as White Hun. They were driven from their seats somewhere between China and Khotan, by the great Turkish race of Ilioug-nu. After sonie intermediate halts, they arrived first in Tft WW1 or Fargliana, aud afterwards in Tahia or liactriana, where they destroyed the Greek dynasty, and settled them selves. The Chinese emperor WaS desirous of opening communication with them in order to excite a diversion against the Hiong-nu, the consMot disturbers of the Chinese frontier, and about ;Lc. 135 he sent for this purpose a party under an officer called Chang-kian. On their way they were caught by the Hiong-nu, and kept prisoners for ten years. Chang-kian then escaped with some of his comrades, but, adhering to his mission, succeeded in reaching Tawan, where he was well received by the people, who were ac quainted by fame with the power and riches of China, though they had never had any direct communication with that country. Finding that the Yuchi had gone south to Bactriana, he fol lowed them thither, but failed to induce them to quit their new seats upon the Oxus to return to their eastern deserts and battle with the Hiong-nu.
During the first century, the power of China had decayed, and the Hiong-nu recovered their ascendency. In A.D. 83, however, Panchao, one of the most illustrious commanders in the Chinese annals, appeared in the field, aaad in a few years recovered the Uigur coimtry and all Western Tartary to the empire.
The Yuchi and other kindred tribes in vaded Sogdiana about B.c. 127-126, and finally, about n.c. 120, conquered the whole of Bactria. They subsequently conquered Kabul, and occupied the country between that city and the Indus. Before the Christian era they were firmly seated on that river, and, under'the great king Kanishka, had become an Indian power of very considerable importance. Kanishka is variously supposed to have reigned from about A.D. 20 to 40, while another account makes him the founder of the Saka era A.D. 79. The power of these Turushka kings spread over all the Panjab, southwards as far as Muttra on the Jumna, in the first century of the Christian era. At the same time, another body, the Sah, who also used the Saka era, crossed the Indus lower down, and. occupied the province of Gujerat. From the time of Kanishka, a con tinuous succession of tribes of Scythian origin poured across the Upper Indus 'into India, each more Turanian than the one preceding it, till the Moghul conquest of India in the 15th century. The western races distinguished as Yavana, who inay have been the Bactrians driven by the Yuchi from their homes B.C. 150 or 130, and who ap peared in Orissa before and about the Christian era ; the Camboja, who joined in the advancing races, seem to have come from a country between Kandahar and Kabul ; and the Saka, the classic Sacm or Scythians, pressed on with the rest, and were forroidable during the first four centuries of the Christian era, till defeated by king Vikram aditya.
According to Chinese authorities, the Yuchi retained their hold in India certainly till A.D. 222 (J. A. S. B. vi. p. 63), and probably for some time longer, but their power seems to have been then on the wane.—Fergusson, pp. 27, 28 ; Walter Elliot; M. L. S.
