During the later years of the Spring and Autumn Period, the Kingdom Jin was divided by the three families Wei, Han and Zhao into three kingdoms.

Marquis Wen of Wei was a wise ruler capable of employing talents. He sent Yue Yang to annihilate the Kingdom of Zhongshan and Ximen Bao to govern the County of Ye. He appointed the infamous Wu Qi as the general to fight the Kingdom of Qin and exploit the area around the West River and Li Kui as the prime minister to carry out reform in Wei. Under his rule, the Kingdom of Wei became stronger and stronger.

After Marquis Wen of Wei died, his sons and grandsons were nothing compared to him. They made little of talented people and kept starting wars. The Kingdom of Wei declined in strength. When the Qin army took control of Daliang, capital of Wei, in 225 B.C., Wei fell.
