Jin dynasty (1115–1234)

The Jin dynasty (/dʒɪn/, Chinese: 金朝; pinyin: Jīn cháo), officially known as the Great Jin (大金; Dà Jīn), was a Jurchen-led imperial dynasty of China and empire ruled by the Wanyan clan that existed between 1115 and 1234. It is also often called the Jurchen dynasty or the Jurchen Jin after the ruling Jurchen people. At its peak, the empire extended from Outer Manchuria in the north to the Qinling–Huaihe Line in the south.

The Jin dynasty emerged from Wanyan Aguda's rebellion against the Liao dynasty (916–1125), which held sway over northern China until being driven by the nascent Jin to the Western Regions, where they would become known in Chinese historiography as the Western Liao. After conquering the Liao territory, the Jin launched a century-long campaign against the Song dynasty (960–1279) based in southern China, whose rulers were ethnically Han Chinese. Over the course of the Jin's rule, their emperors adapted to Han customs and even fortified the Great Wall against the ascendant Mongol Empire. The Jin also oversaw a number of internal cultural advances, such as the revival of Confucianism.

In 1211, the Mongols, led by Genghis Khan, invaded the Jin Empire, winning several victories. Over the span of 23 years, the Jin faced several defeats, internal revolts, defections, and coups. They were finally conquered by the Mongols in 1234.
