明朝末年,后金汗努尔哈赤崛起以后,在辽东地区,明朝与蒙古的尖锐矛盾降居次要地位,明朝与后金的矛盾上升为主要矛盾。但蒙古倾向如何,对明与后金力量的对比有关键的意义。本文着重论述明朝与辽东蒙古内喀尔喀部、喀喇沁部、察哈尔部的关系。至于与明朝直接发生联系较少的科尔沁等部,本文从略。 In the late Ming Dynasty, after the rise of Jinhan Nurhachu, sharp contradictions between the Ming Dynasty and Mongolia took the second place in the Liaodong area. The contradiction between the Ming Dynasty and the Later Jin Dynasty rose as the main contradiction. However, how Mongolian tendencies are crucial to the contrast between the power of the Ming Dynasty and that of the latter. This article focuses on the relationship between the Ming Dynasty and Inner Mongolia, Inner Kashgar, Kalaqin, Chahar. As for the less directly with the Ming Dynasty Horqin and other ministries, this article omitted.
