The Jin Dynasty was founded in what would become northern Manchuria by the Jurchen tribal chieftan Wányán Āgǔdǎ (完顏阿骨打) in 1115. In 1125, it successfully annihilated the Liao Dynasty which had held sway over northern China, including Manchuria and part of the Mongol region for several centuries. Also at this time, the Jin made overtures to the Korean kingdom of Goryeo, which Emperor Yejong refused. On January 9, 1127 Jin forces ransacked Kaifeng, capital of the Northern Song Dynasty, capturing both Emperor Qinzong, and his father, Emperor Huizong, who had abdicated in panic in the face of Jin forces. Following the fall of Kaifeng, Song forces under the leadership of the succeeding Southern Song Dynasty continued to fight for over a decade with Jin forces, eventually signing the Treaty of Shaoxing in 1141, calling for the cessation of all Song land north of the Huai River to the Jin and the execution of Song General Yue Fei in return for peace.
After taking over Northern China, the Jin Dynasty became increasingly Sinicized. About three million people, half of them Jurchens, migrated south into northern China over two decades, and this minority governed about thirty million Chinese. The Jurchens were given land grants and organized society into 1,000 households (猛安 - meng'an) and 100 households (謀克 - mouke). Many married Hans, although the ban on Jurchen nobles marrying Hans was not lifted until 1191. After Jin Emperor Tàizōng (太宗) died in 1135, the next three Jin emperors were grandsons of Wányán Āgǔdǎ by three different princes. Young Jin Emperor Xīzōng (熙宗) (r. 1135-1149) studied the classics and wrote Chinese poetry. He adopted Han cultural traditions, but the Jurchen nobles had the top positions.
Later in life, Emperor Xīzōng became an alcoholic and executed many officials for criticizing him. He also had Jurchen leaders who opposed him murdered, even those in his own Wanyan family clan. In 1149 he was murdered by a cabal of relatives and nobles, who made his cousin Wányán Liàng (完顏亮) the next Jin emperor. Because of the brutality of both his domestic and foreign policy, Wanyan Liang was posthumously demoted from the position of emperor. Consequently, historians have commonly referred to him by the posthumous name of Prince Hǎilíng (海陵王).
In 1153, Prince Hǎilíng moved the empire's "southern" capital from Huining Fu in northern Manchuria (south of present-day Harbin) to Zhongdu (now Beijing). Four years later in 1157, he razed Beijing, including the nobles’ residences, and moved the Jurchen southern capital from Beijing to Kaifeng and began to reconstruct it (since its sack in 1127). Prince Hǎilíng also tried to suppress dissent by killing Jurchen nobles, executing 155 princes.
Emperor Prince Hǎilíng attacked the Southern Song in 1161. Meanwhile, two simultaneous rebellions of Jurchen nobles, led by soon-to-be crowned Wányán Yōng (完顏雍), and Khitan tribesman erupted in Manchuria, forcing the Jin Dynasty to withdraw its troops from southern China to quell the uprisings. The Jin were defeated in the Battle of Caishi and Battle of Tangdao. With a depleted military force, Prince Hǎilíng failed to make headway in his attempted invasion of the Song. Finally he was assassinated by his own generals in December of 1161. His son and heir was also assassinated in the capital. Although crowned in October, Wányán Yōng was not officially recognized as Jin Emperor Shìzōng (世宗) until the murder of Prince Hǎilíng's heir. The Khitan uprising was not suppressed until 1164; their horses were confiscated so that the rebels had to take up farming. Other Khitan and Xi cavalry units had been incorporated into the Jin army. Because these internal uprisings had severely weakened the Jin’s capacity to confront the Southern Song militarily, the Jin court under Emperor Shizong began negotiating for peace. The Treaty of Lóngxīng (隆興和議) was signed in 1164 and ushered over 40 years of peace between the two empires.
In the early 1180s Emperor Shìzōng instituted a restructuring of 200 meng'an units to remove tax abuses and help Jurchens. Communal farming was encouraged. The Jin empire prospered and had a large surplus of grain in reserve. Shìzōng's grandson, Emperor Zhāngzōng (章宗) (r. 1189-1208) venerated Jurchen values, but he also immersed himself in Chinese culture and married an ethnic Han woman. The Taihe Code of law was promulgated in 1201 and was based mostly on the Tang Code. In 1207 the Song tried to invade, but the Jin forces effectively repulsed them. In the peace agreement the Song had to pay higher annual indemnities and behead Hán Tūozhòu (韩侂胄), the leader of their war party.
In his book Empire of The Steppes, Grousset reports that the Mongols were always amazed at the valor of the Jin warriors, who held out until seven years after the death of Genghis Khan himself.
