How was the Later Jin Dynasty established?

Houjin, the name of the dynasty, 1616~1644. The Manchus are a descendant of the Jurchen tribe and have always lived in Northeast China. During the Yongle period of the Ming Dynasty, the Ming Dynasty wanted to suppress the remaining forces of the Northern Yuan Dynasty, so the Ming Dynasty established the Far East Command Department in Northeast China and began to control various Jurchen tribes.

Timur, the fierce brother of the Jurchen tribe in Jianzhou (the sixth ancestor of Nurhachi), was the governor of Jianzhou's left guard in the Ming Dynasty. The tribes in the north were powerful and went south to oppress Jianzhou. Meng brother Timur was killed, and the Jianzhou tribe was forced to move south, eventually settling in Hetuala.

After moving south, the Jianzhou Department had close contacts with the Central Plains region, social productivity increased significantly, the economy prospered, and the Eight Banners system was immediately established. At this time, it was Nurhachi who served as the leader of the Jianzhou Department in the Ming Dynasty. In 1583 (the 11th year of Wanli in the Ming Dynasty), Nurhachi was appointed as the commander. With his ancestors and father's legacy, he successively annexed the four Haixi tribes, conquered the Jurchen tribes in the East China Sea, and unified the Jurchen tribes scattered in Manchuria.

In 1616 (the forty-fourth year of Wanli in the Ming Dynasty), Nurhachi proclaimed himself khan in Hetuala, established the Jin Dynasty (called Hou Jin in history), and changed the destiny of the Yuan Dynasty.

In 1618 (the third year of Tianming and the forty-sixth year of Wanli in the Ming Dynasty), Nurhachi published a proclamation called "Seven Hatreds" to protest against the Ming Dynasty, and began to openly raise troops to rebel against the Ming Dynasty.

After the death of Aixinjueluo Nurhaci, Aixinjueluo Huang Taiji came to the throne. In 1636 (the ninth year of Chongzhen in the Ming Dynasty), Huang Taiji changed the country's name to "Qing" and his reign name Chongde. , the "Dajin" national code ceased to be used.
