Xin dynasty
Ruzi Ying (; 5 – 25 CE), personal name Liu Ying (劉嬰), was the last ruler of the Chinese Western Han Dynasty. He was the titular ruler of the Han Empire from 6 CE to 9 CE, even though he did not officially ascend to the throne and only assumed the title of crown prince. After Emperor Ai 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 the 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, a number of ambitious individuals claimed to be restoring the Han dynasty. In 25 CE, a rebellion against the Gengshi Emperor used the former Emperor Ruzi as a focus, and when the rebellion was defeated, Liu Ying (Ruzi) was killed. He is often viewed as an innocent child who was the victim of tragic circumstances.
