明朝17位英杰在东北地区设立建州三卫仿佛是天地之灵在无人之地播下了和平的种子
在永乐二年（1404年），明朝在东北地区设立了建州卫，任命女真胡里改部首领阿哈出为指挥使。随后，又建立了建州左卫，由斡朵里部首领猛哥帖木儿（即爱新觉罗孟特穆）担任指挥使。猛哥帖木儿去世后，建州左卫因其弟凡察和子董山的争斗而分裂。正统七年（1442年），明朝从建州左卫中又分出了建州右卫，让凡察掌管右卫，董山掌管左卫。这一系列动作 eventually led to the formation of the Build State Tatars. Among them, Dongshan's Build State Left Army became the most powerful and even took on the role of leader among the three armies. Seeing the growing power of the Tatars, Ming implemented policies to divide and limit their territory, which only fueled resentment among various tribes. Dongshan allied with Haixi Tatars and launched attacks against Ming-controlled towns in Liaodong, but this ultimately resulted in his own death at Ming hands during what was later known as Chenghua Chishe (平定). The build state tatars suffered heavy losses. This Dongshan was a direct ancestor of Nurhaci, who would later unite all Tatar tribes and establish the Later Jin regime in 1616 at Hetu Ala. As Ming weakened further, Build State Tatars rose again under Nurhaci's leadership before he became an "excavator" for Ming by unifying all tribes and founding Later Jin in 1616.
