We all know that the Eastern Han Dynasty perished as a result of the eunuch dictatorship and the chaotic administration of foreign relatives, and in the Western Han Dynasty, there was at most a situation of foreign relations monopolizing power, and in the Eastern Han Dynasty, there was a situation in which foreign relatives and eunuchs alternated dictatorships. The root cause of the demise of the Eastern Han Dynasty had a lot to do with the dictatorship of eunuchs at that time, and the culprit was the fourth emperor of the Eastern Han Dynasty, Han He. Because from the beginning of the Han and Emperor, eunuchs entered the political institutions of the Eastern Han Dynasty and began to interfere in the government, so the Eastern Han Dynasty went into decline and eventually perished, and the Han and the Emperor could not be separated.
One of the biggest features of the Eastern Han Dynasty is that the emperors are very young in age, so the power is controlled by foreign forces. Therefore, after the death of many emperors in the Eastern Han Dynasty, the power of the new emperor to succeed to the throne was overshadowed by foreign forces. After the death of Emperor Zhang of Han, his 10-year-old son Liu Zhao succeeded to the throne as Emperor He of Han. Emperor Liu Zhao's mother Liang Guiren was framed to death by Empress Dou shortly after Liu Zhao's birth and was raised by Empress Dou. After Liu Zhao succeeded to the throne, empress Dowager Dou was made empress dowager, and because Liu Zhao was still a small hairy child at that time, she was called by Empress Dowager Dou.
After Empress Dowager Dou ascended the throne, his elder brother Dou Xian was promoted to shizhong (侍中), and his younger brother Dou Du (窦笃) was appointed as the general of the Tiger Ben Zhonglang(ゥ中郎). One in charge of the secrets of the imperial court, one in charge of the emperor's forbidden army, it can be said that the power of the Eastern Han Dynasty was controlled by the Dou family. In particular, Dou Xian broke the Northern Xiongnu and became famous, so he held great power in the government, and it can be said that Fei Fei also raised assassins to assassinate bureaucrats who had different political views. Because of Empress Dou's indulgence in the Dou brothers, many upright ministers in the imperial court were dissatisfied. Moreover, Dou Xian's son-in-law Guo Ju(Guo Ju) plotted to assassinate Emperor He of Han because of Empress Dou's favor. Han and The Emperor learned of their plot and intended to seize power. In 92 AD, when Emperor Hanhe was only 14 years old, his power had been emptied, and he had no pro-government and no military power. The Han and Emperor Liu Zhao wanted to get rid of the Dou family, but he could not communicate with the outside world, so he had to rely on the eunuch Zhongzhong's servant Zheng Zhong to conspire to get rid of Dou Xian. Since Dou Xian was leading troops outside and not in the capital, Han he and Emperor were afraid of Dou Xian's rebellion and did not send troops for the time being.
At that time, Liu Qing, the king of Qinghe, often entered the palace to visit Liu Zhao, and once stayed at the palace. In order to contact Liu Qing, Emperor Han sent Zheng Zhong to inform Liu Qing of the incident and ask him to help get rid of Dou Xian. On June 23, 92, The Han and Emperor Liu Zhao, visiting the Northern Palace, ordered JinWu and the Five Lieutenants of the Northern Army to lead troops to prepare for battle, garrison the Nangong and the Northern Palace, and wait for Dou Xian to enter the capital and immediately close the city gates, so that Dou Xian's party was eliminated. Dou Xian was demoted back to the feudal state and committed suicide soon after. After the Dou Xian family was eliminated, Emperor Han and Emperor took power, and the eunuch Zheng Zhong, because of his merits, was favored by Emperor Han and managed all the affairs of the harem, and even major state affairs would be discussed with Zheng Zhong. Therefore, the Han and Emperors opened a precedent for eunuchs to interfere in politics. After that, as long as the emperor's power was overridden by foreign relatives, the emperor would win over the eunuchs. Therefore, in the last years of the Eastern Han Dynasty, there was a "Ten Constant Attendant Rebellion" eunuch and a foreign relative He Jinhuo, and as a result, the power of the Eastern Han Dynasty fell into the hands of the fanzhen, which eventually led to the demise of the Eastern Han Dynasty.
