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.)
History of the Han dynasty
Eventually, due to his good reputation, Huo Qubing's half-brother Huo Guang was entrusted by Wu to form a triumvirate regency alongside ethnically Xiongnu Jin Midi (d. 86 BCE) and Shangguan Jie (上官桀) (d. 80 BCE) over the court of his successor, the child Liu Fuling, known posthumously as Emperor Zhao of Han (r. 87–74 BCE). Jin Midi died a year later and by 80 BCE Shangguan Jie and Imperial Counselor Sang Hongyang were executed when they were accused of supporting Emperor Zhao's older brother Liu Dan (劉旦) the King of Yan as emperor; this gave Huo unrivaled power. However, he did not abuse his power in the eyes of the Confucian establishment and gained popularity for reducing Emperor Wu's taxes.
