After Red Cliffs Liu Bei took southern Jing Province, seized Yi Province (modern Sichuan) in 214 and Hanzhong in 219, styling himself King of Hanzhong. On hearing that Cao Pi had founded Wei, he declared himself emperor at Chengdu in the fourth month of 221 and named his state Han, asserting the legitimacy of the Han house. Historians call it Shu Han to distinguish it from the earlier Han. Zhuge Liang became chancellor.
