Jin Dynasty (1115-1234) was a northern regime established by the Nuzhen nationality in the history of China, which lasted for 120 years. Jurchen was originally a vassal of the Liao Dynasty, and it was celebrated for four years (1 1 14). After Jin Taizu Hong Yan unified the various departments of Jurchen, he rose up against the Liao Dynasty. The following year, the capital was established in Huining Prefecture, Beijing (now Harbin City, Heilongjiang Province), and Daikin and Jianyuan received the title of "receiving the country". The Liao Dynasty perished at 1 125, and the Northern Song Dynasty perished two years later. In the first year of Zhenyuan (1 153), Wan Yanliang, the king of Hailing, moved to Daxing House in Zhongdu (now Beijing).
During the reign, Jin's political culture reached its peak, and it turned from prosperity to decline in the later period of the reign. After Jin Xuanzong succeeded to the throne, his internal politics was corrupt, the people were poor, and he was invaded by Mongolia, so he was forced to move his capital to Bianjing (now Kaifeng, Henan). Jurchen nobles occupied the fields in North China and enslaved the Han nationality, which aggravated the contradiction between the two sides. With the decline of the Jin Dynasty, the Han people rose up in succession. 1234, Jin fell under the attack of the Southern Song Dynasty and Mongolia.
During the heyday of the Jin Dynasty, the ruling territory included the north of Huaihe River in Chinese mainland today, most of the Qinling Mountains in the northeast and the Far East of the Russian Federation, with a vast territory. As a conquering dynasty, Jin has a strong tribal system. At first, it adopted the aristocratic collegiate system, and after absorbing the system of Liao and Song Dynasties, it gradually moved from dual politics to a single Sino-French system.
