In 497 BC a dispute broke out between the Zhao clan, and the Fan and Zhonghang clans. The Fan and Zhonghang forces attacked Zhao,but were defeated and forced to retreat to the city of Zhaoge as the other three other clans (Han, Wei, and Zhi) came to Zhao's defence. Seven years later, in 490 BC the combined Jin forces decisively defeated Fan Jishe and Zhonghang Yin, leaders of their respective clans, forcing them to flee to the State of Qi. Later the Han, Zhao, and Wei clans would grow stronger leading to the partition Jin from 481 BCE into the new states of Han, Zhao, and Wei and finally destruction of the Jin State in 386 BCE.Sima Guang, "Comprehensive Mirror to Aid in Government"
