蒙金战争初期,双方交战地点很少涉及东北地区,但金朝的败退、东京城被攻陷和都城南迁等事件,对东北局势起到很大影响。东北地区先后出现耶律留哥和蒲鲜万奴等叛金势力。随着蒙军进入辽东地区,占领城镇和收降各支叛军,辽东地区暂时呈现出蒙军占据主导的局面。 In the early days of the Mongolian War, the belligerent locations of the two sides seldom involved the northeast region. However, events such as the retreat of the Jin dynasty, the fall of Tokyo city, and the southward move of the capital city exerted a great influence on the situation in the northeast. The northeastern region has appeared Yeluoligou and Pu Xian Wan slavery rebel forces. As the Mongolian army entered the area of ​​Liaodong, occupied towns and closed down all the rebel forces, the Liaodong area temporarily assumed the dominant position of the Mongolian Army.
