The Jin Dynasty was a Chinese dynasty that ruled from 1115 to 1234. It was founded by the Jurchen people, who overthrew the Liao Dynasty. The Jin Dynasty is known for its military strength and territorial expansion, particularly in northern China. During its reign, the Jin Dynasty established a complex bureaucracy and promoted trade and agriculture. It also faced challenges, including conflicts with the Song Dynasty and internal strife. The dynasty ultimately fell to the Mongol Empire, marking the end of its rule and the beginning of a new era in Chinese history.
