At the end of the New Dynasty, the Red Eyebrow Uprising in Greenwood broke out, and Liu Xiu, the imperial clan of the Western Han Dynasty, took advantage of the situation. In AD 25, Liu Xiu proclaimed himself emperor and made Luoyang (now Luoyang, Henan Province) his capital, continuing the title of "Han", which was called the Eastern Han Dynasty in history. During the Eastern Han Dynasty, the power of Sangong was greatly weakened, and the power of Shangshutai was promoted. During the reign of Emperor Hanming and Zhang Han, the Eastern Han Dynasty entered its heyday, which is known as the reign of Zhang Ming. In the later period of Zhang Han, consorts became more and more overbearing. After Han and Emperor ascended the throne, the consorts were eliminated, and the national strength of the Eastern Han Dynasty reached its peak, which was known as Yuan Long through the ages.
In the middle and late Eastern Han Dynasty, the Empress Dowager said that consorts were in charge, and the young monarch could be in charge with the help of eunuchs. History is called the battle between officials, the increasingly corrupt political affairs, and the powerful forces wantonly annexed land. During the period of Emperor Huan and Emperor Ling of Han Dynasty, the peasants could not bear multiple cruel oppression, and the court ordered all states and counties to recruit soldiers by themselves, which basically put down the rebellion, but led to the self-respect of local strongmen. In the first year of Chuping (190), Dong Zhuo took Xian Di to Chang 'an? From then on, the imperial court was sidelined, which opened the prelude to the warlord melee in the late Eastern Han Dynasty. After Dong Zhuo was killed, he returned to the west in the first year of Jian 'an (196), and Cao Cao welcomed Emperor Xian of Han Dynasty to move to Xuchang. In 220 AD, Cao Pi usurped the Han Dynasty, and the Eastern Han Dynasty was destroyed, entering the period of the Three Kingdoms regime.
The Eastern Han Dynasty made outstanding achievements in culture, science and technology, military affairs and Buddhism. Culturally, Zheng Xuan pushed the study of Confucian classics to a peak and created Zheng Xue. Technically, Cai Lun improved papermaking, and Zhang Heng invented the seismograph and the armillary sphere, which militarily forced the northern Xiongnu to move westward. During this period, Buddhism was introduced into China through the White Horse Temple. During the Eastern Han Dynasty, the powerful landlords expanded to form gentry, and the Xiongnu, Qiang and Di nationalities moved inward. After the northern Xiongnu moved westward, Xianbei people occupied Mobei, which had a far-reaching impact on later generations.
Precautions:
Before Emperor Shun of Han Dynasty, the young emperor was supported by Empress Yan (Empress Han An) at first. Liu Yi died after being emperor for half a year, and Shun Di took the opportunity to ascend the throne. At present, history books and scholars do not classify Liu Yi as the Emperor of the Han Dynasty, while others call him the Northern Xiang Hou.
Xian Di was once the (later) emperor Liu Bian. He was the emperor for four months and spent a lot of time in asylum. At present, history books and scholars have not classified Liu Bian as the Emperor of the Han Dynasty. However, after Dong Zhuo poisoned the young emperor Liu Bian, he was renamed Hongnong Huaiwang. Therefore, the world called the young emperor "King of Hongnong".
Emperor Zhaolie of Shu Han was posthumously named "filial piety", but Liu Xie did not die when he was mourned.
During the Jian 'an period, the temple names of emperors other than Xianzong were summoned.
In December of the first year of Yong Han (189), except for Guangxi, Zhao Ning and Yong Han, it was called six years in Zhong Ping.
Kai, Yi, Shu and Zhong were the emperors of Han 'an, Huan and Ling.
