Ruzi Ying
Ruzi Ying (; 5 – 25), also known as Emperor Ruzi of Han and the personal name of Liu Ying (劉嬰), was the last emperor of the Chinese Western Han Dynasty from 6 CE to 9 CE. After Emperor Ai of Han and Emperor Ping died without heirs, Wang Mang chose the youngest of the available successors in order to maintain his power in the government. The child Ying was soon deposed by Wang Mang who declared the Xin Dynasty in place of the Han. During Xin Dynasty, Ying was under effective house arrest—so much so that as an adult, he did not even know the names of common animals. Before and after the Xin Dynasty was overthrown in 23 CE, many ambitious people claimed to be restoring the Han dynasty. In 25 CE, a rebellion against the temporary Gengshi Emperor used the former Emperor Ruzi as a focus, and when the rebellion was defeated, he was killed. He is often viewed as an innocent child who was the victim of tragic circumstances. (The expression "Emperor Ruzi" is a misnomer, as he never assumed the throne and was only named crown prince. Nevertheless, he is commonly referred to as such.)
Xi Zuochi
Even the work's title, naming the Han and Jin dynasties without mention of the intervening Wei, is indicative of its primary thrust. 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. Late in life, in his final memorial to the throne, Xi Zuochi laid bare his rationale and method behind delegitimating Wei while conducting the balancing act of considering the Jin dynasty still legitimate.
