A Historical Research Of The Nomadic Tribes Of The Prairie Of Eurasia And Tibetan-Yi Corridor: A Case Of The Mongols As The Centre

Nomadic Tribes of the Prairie of Eurasia played an important part in the formation and evolution of Tibetan-Yi Corridor. In the beginning of 13th Centry, rising from the north Mongolia plateau, Mongolian minority not only carried on the tie of past various Nomadic Tribes of the Prairie of Eurasia and Tibetan-Yi Corridor, but also pushed it forward.In order to break through the natural barrier of yellow river and Yangtze River which ran through the south and the north horizontally to conquer the Jin state, South Sung state etc.in the Central plains, Genghis Khan, Mongolian ruler and the like correspondently put forward the strategy of conquer the southwest and various minorities first, then the central plains" in Mongolian military conquest from the northern plateau to south expansion. To wit, it attacked the central power at the side of wing, with the help of the manpower, material resources of southwest minorities and matched with the positive battlefield from both flanks. Tibetan-Yi Corridor, an important transportation hub between the northwest and the southwest, was therefore viewed as Mongolian military target and became the strategic place of the implement" conquer the southwest and various minorities first, then the central plains". Since 1227, Mongolia state continuously began to resort to arms in the region along with whole conquer of the Jin State, South Sung state and Tibet with the development of the situation. In 1253, it was basically conquered byMongolia along with Kublai Khan invading the south, the expedition of Dali state, and fulfillment of the strategy. On this foundation, Yuan Dynasty employed the administrative division, appointed the officers to control. It also governed with the help of local people according to the actual circumstance of the region. As a result, Tibetan-Yi Corridor was not only under the control of the central political power which brought into the big unification completely for the first time, but also established the future basis of the Tushi system.Mongolia returned Tibetan-Yi Corridor to Ming Dynasty after its collapse, but remained its pressure and influence in the area even though they retreated to the north plateau, which forced Ming Dynasty to employ the defense policy of isolating Mongols and correspondingly adjusted its governance of the region at the northwest. At the beginning of 16th centry, along with the decline of Ming Dynasty and flabbiness of its border defense, the Mongols finally broke the Ming Dynasty's block, entered the region of Qing-Hai Lake, and further went down south to encroach upon the Tibetan-Yi Corridor. The Mongols accepted Tibetan Buddhism gradually, hi Qinghai Tumote Mongols allied with the Yellow-Hat sect of Tibetan Buddhism religiously and politically to extend the influence there. This objectively urged some aboriginal politics, religious parties to ally, boycott and resist the Shamanism and Mongolia's expansion, so did the Bali Tushi and Muli Tushi successively. At the end of 30's of the 17th century, Qosot Mongolia, moving into Qinghai from the south of Tianshan, went down south into the region to keep on the continuous military aggression over a long period of time, in taking charge of the Bali Tushi and Muli Tushi and got the upper hand as the predominant invaders. It obtained many politic and economic benefits, therefore conflicted with Qing Dynasty. Qosot Mongolia was forced to retreat successively from Tibetan-Yi Corridor as Qing Dynasty advanced from the east to the west. In the 20's of the 18th century, Luopuzhangdanjin failed to fight against Qing Dynasty, which announced all its governance completely in the hand of Qing Dynasty.Mongolia's invasion, caused northern steppe culture to spared to Tibetan-YiCorridor, among them, the main being national migration. Since the 13th Centry, with the immigration of the north Nomadic Tribes of the Prairie of Eurasia, mainly Mongolia, most of which merged into other minorities with many remaining culture relics, particularly with legends of forefather origins of the northern Nomadic Tribes of the Prairie of Eurasia centered by Mongolia spread extensively. In the dissertation forefather origins and culture relics were summarized into 6 types and the writer analyzed one by one to prove the interaction between the northern Nomadic Tribes of the Prairie of Eurasia centered by Mongolia and the aborigines toward the influence of the ethnical politics.
