明代的瓦刺、清代的卫拉特等都是十三世纪斡亦剌惕的不同音译。斡亦刺惕是蒙古古老部落之一。成吉思·汗统一蒙古各部后,将斡亦刺惕划分为四个千户。可能是由于这个原因,后来不管发生什么变化,它不仅习惯上被称为四卫拉特,而且它终是由四个部分组成。从十五世纪初到十八世纪中叶,卫拉特在蒙古史上发挥了重要作用。因此,研究卫拉特史有着深远的历史意义和重要的现实意义。 Wa thorn in the Ming Dynasty and the Oirat in the Qing dynasty were all transliterations of the thirteenth century. Mo is also vigilant is one of Mongolia’s ancient tribes. After Genghis Khan unified the ministries in Mongolia, he divided himself into four thousand families. It may be for this reason that later, no matter what changed, not only was it customarily referred to as the IVA, but it eventually consisted of four parts. From the beginning of the fifteenth century to the mid-eighteenth century, Oirat played an important role in the history of Mongolia. Therefore, it is of far-reaching historic significance and important practical significance to study Velater’s history.
