Eunuch autocracy in the Eastern Han Dynasty began when he ascended the throne at the age of ten. Since then, the emperors of the Eastern Han Dynasty have acceded to the throne at a young age, among which the youngest Shang emperor has just turned 100 days when he acceded to the throne, and Huan emperor is older when he acceded to the throne, but he is only fifteen years old. Whenever the little emperor came to power, because he was young and ignorant, state affairs were often in the hands of his mother, and her mother often relied on her consorts for power, which led to the situation that consorts were authoritarian. When the emperor grows up, he naturally wants to take power in person, which will inevitably form a conflict of interest with his consorts. In the struggle between the emperor and his consorts, because the emperor was lonely in his childhood, he could rely on eunuchs who lived together day and night. Once eunuchs helped the emperor gain power, they would be proud of themselves and monopolize the government. Eunuchs became more rampant in the Eastern Han Dynasty after Emperor Huan destroyed Liang Ji Group. From this to the demise of the Eastern Han Dynasty, eunuchs were authoritarian and good at politics, repelling dissidents and repeatedly creating party struggles, which not only ruined the political affairs, but also deepened the political darkness.
