 The annals began with Emperor Guangwu of Han, restorer of the dynasty and founding emperor of the Eastern (or Later) Han, and continued through to the time of Emperor Min of Jin, final emperor of the Western Jin (i.e.years CE 25–317).Although his primary goal was to argue that ritual abdication was insufficient to achieve a legitimate mandate, Xi Zuochi's aims had the secondary effect of legitimating Liu Bei's Shu Han as the legitimate successor to the Han dynasty, which he displayed by employing the Shu Han calendar, going so far as to use dynastic founder Emperor Wu of Jin's taboo personal name in recording the events of Liu Shan's final regnal year.
