At the end of the Eastern Han Dynasty, the struggle between consorts and eunuchs continued, which made state affairs increasingly corrupt, and then the Yellow Scarf Uprising broke out. Liu Bei entered his official career because he made great achievements in suppressing the peasant uprising. But not long after, He Jin and Dong Zhuo were defeated, and the world situation gradually turned into a warlord melee. Liu Bei ran around in the melee. After Battle of Red Cliffs recovered all parts of Jingzhou, he advanced to capture Hanzhong and finally established the Shu-Han regime.

Shu and Han dynasties occupied Jingzhou and Yizhou in their heyday. After Guan Yu lost Jingzhou and Liu Bei's Yiling, his national strength was damaged, and then Zhuge Liang restored the national strength of Shu, forcing the southern and central regions to yield, and gained a lot of natural resources such as materials, population, equipment and minerals, and his national strength became strong again. Militarily, Shu Han often took the initiative, but gradually declined in the later period, and was finally destroyed by the Sima family who controlled Cao Wei.
