In 349 BCE, the Han and Zhao states divided the remaining Jin territory between themselves, thus completely destroying the State of Jin.

The rivalry survived the death of Li Keyong, whose son Li Cunxu continued to expand Jin territories at the expense of the Later Liang.

Even so, the Jurchens was checked by General Yue Fei and almost entirely routed before they get back to Jin territory.

He then advanced with three armies into the heart of Jin territory, between the Great Wall and the Yellow River.

He and his followers are thought to have established a base within Jin territory.

Energized by Lu's arrival, as Lu was able to serve as a guide for attacks on Jin territory, Khitan's Emperor Taizu decided to launch a major attack on Lulong.

Throughout this time however, Temüjin continued to build his forces and by 1213 had an army so powerful that they conquered all of the Jin territory up to the Great Wall of China.

In order to alleviate the shortages of labor caused by the Three Kingdoms wars, the Jin let millions of non-Chinese people move into Jin territory.

However, during this period many social problems developed as well, the most pressing of which was the migration of barbarian tribes into Jin territory, to the point where they outnumbered Han Chinese in some regions.

After Zu's death in 321, however, Later Zhao forces began to again attack Jin, gradually capturing Jin territory between the Yellow River and the Huai River.
