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.)
Emperor Xian of Han
In late 220, some months after Cao Cao's death, Cao Cao's successor, Cao Pi, forced Emperor Xian to abdicate the throne to him. He then established the state of Cao Wei with himself as the new emperor – an event marking the formal end of the Han dynasty and the beginning of the Three Kingdoms period in China. The dethroned Emperor Xian received the noble title Duke of Shanyang (山陽公) from Cao Pi and spent the rest of his life in comfort and enjoyed preferential treatment. He died on 21 April 234, about 14 years after the fall of the Han dynasty.
