Eastern Han Dynasty

Overview

The Eastern Han Dynasty (25-220 CE) was the latter period of China's Han Dynasty, following the Western Han Dynasty (202 BCE-9 CE). Founded by Emperor Guangwu (Liu Xiu), the Eastern Han continued the "Han" imperial name but established its capital at Luoyang, which was east of the Western Han capital Chang'an. For this reason, it was historically referred to as the "Eastern Han" (Dong Han) or "Later Han" (Hou Han). The dynasty lasted for nearly 200 years and witnessed significant cultural, technological, and political developments, as well as periods of prosperity and decline.

History

The End of Xin Dynasty and Turmoil

During the late Western Han Dynasty, social contradictions intensified dramatically. After Wang Mang usurped the Han throne and established the Xin Dynasty (9-23 CE), he implemented a series of new policies including the "Field Commandment" and "Private Slaves Commandment" in an attempt to alleviate the worsening social conflicts. However, Wang Mang's reforms disrupted the vested interests of powerful landlords and upper-class bureaucrats, who fiercely opposed them. Coupled with the idealistic and archaic nature of his reforms and natural disasters, these policies ultimately backfired, intensifying social tensions. This led to the outbreak of the Linlin (Green Forest) and Chimei (Red Eyebrow) rebellions during the Tianfeng era (14-19 CE) of the Xin Dynasty. The rebellion quickly spread across the empire, plunging the nation into chaos and ultimately causing the downfall of the Xin Dynasty.

The Founding of the Eastern Han

Liu Xiu, a ninth-generation descendant of Han Dynasty founder Emperor Gaozu (Liu Bang), emerged as a key figure during this turbulent period. In 22 CE, Liu Xiu and his elder brother Liu Yan raised the "Chunling Army" in Chunling to restore Liu family rule. In 23 CE, Liu Xiu achieved a decisive victory at the Battle of Kunyang, which crippled the military forces of the Xin Dynasty. The same year, the Linlin Army captured Chang'an, and Wang Mang was killed by rebel forces, leading to the collapse of the Xin Dynasty.

After the restoration of the Han Dynasty under Emperor Gengshui (Liu Xuan), Liu Xiu was dispatched to the Hebei region to pacify the provinces and commanderies. There, he defeated Wang Lang and gained the support of powerful landlords and local gentry, establishing a firm base of power in Hebei. By 25 CE, Liu Xiu had effectively broken away from the Gengshui regime. In August of the same year, Liu Xiu ascended to the throne as Emperor Guangwu, restoring the Han Dynasty with the era name Jianwu. He established his capital at Luoyang, beginning what would become the Eastern Han Dynasty.

The Guangwu Restoration Era

Emperor Guangwu implemented a governing philosophy of "rule through gentleness" (rou dao zhi guo), focusing on restoring order after the chaos of the Xin Dynasty's collapse. He retired many military commanders from political positions while promoting civil officials, ensuring that most founding generals returned to their homes as marquises with generous stipends but without political power. Only three individuals—Deng Yu, Li Tong, and Jia Fu—were permitted to participate in major political decisions, and they too avoided political involvement to prevent suspicion.

Emperor Guangwu concentrated power in the imperial court, strengthening central authority while preventing the overreach of officials, imperial relatives, and maternal relatives. He reorganized the government structure by establishing six ministers in the Secretariat (Shangshu Sheng) to manage state affairs, thereby reducing the power of the Three Excellencies (Grand Marshal, Minister over the Masses, and Minister of Works). He also streamlined the administration by merging more than 400 counties and reducing bureaucratic positions by 90%.

The emperor implemented policies to restore agricultural production and improve people's livelihoods. In 30 CE, he restored the land tax rate to one-thirtieth of the harvest, which was lighter than the burden during the late Western Han and the war years. He issued nine edicts releasing slaves or improving their legal status, which freed numerous slaves to become commoners and encouraged displaced people to return to agricultural production. These measures, along with land surveys and tax reforms, gradually stabilized society and led to a period known as the "Guangwu Restoration" (Guangwu Zhongxing).

The Ming and Zhang Reigns

After Emperor Guangwu's death, his son Emperor Ming (Liu Zhuang) ascended the throne. Emperor Ming launched military campaigns against the Northern Xiongnu, sending his generals Dou Gu and Geng Bing to attack the Xiongnu. The Han army advanced to the Tianshan Mountains, defeating the Huyan King and pursuing them to Pulei Lake (present-day Barkol Lake in Xinjiang). This victory led to the submission of various Western Regions states, and in 74 CE, the Protectorate-General of the Western Regions was reestablished, restoring Han control over the region that had been lost for 65 years.

In 69 CE, the Ai Liao Kingdom (present-day Yunnan and northern Myanmar) submitted to Eastern Han rule, and Emperor Ming established Yongchang Commandery in the territory. This expanded Han control in the Yunnan region. During Emperor Ming's reign, Buddhism, which had begun to enter China during the late Western Han, gained further acceptance. Hearing about a deity named Buddha in the Western Regions, Emperor Ming sent envoys to India to obtain Buddhist scriptures and monks, establishing China's first Buddhist temple, the White Horse Temple (Baima Si), in Luoyang.

Emperor Zhang continued his father's policies, maintaining strict control over relatives and officials while promoting talented individuals. He issued edicts to resettle displaced persons and provided poor farmers with seeds and grain from public lands. During this period, known as the "Ming-Zhang Governance" (Ming Zhang Zhi Zhi), the empire enjoyed peace and prosperity. The population grew from 21 million at the end of Emperor Guangwu's reign to 43 million by the end of Emperor Zhang's reign.

The Yongkang Prosperity

Emperor Zhang died in 88 CE, and his son Emperor He (Liu Zhao) ascended the throne at a young age. Initially, his adoptive mother, Empress Dou, served as regent and favored her relatives, particularly her brother Dou Xian, who gained significant power. However, in 92 CE, Emperor He, with the support of officials like Ding Hong, launched a coup against the Dou faction, eliminating their influence and taking personal control of the government.

Emperor He proved to be an active ruler, launching military campaigns against the Northern Xiongnu and defeating the Kushan Empire. He also conquered more than 50 states in the Western Regions, extending Han influence to distant regions. In 97 CE, he sent the envoy Gan Ying to Daqin (the Roman Empire), who reached the eastern coast of the Mediterranean before returning. This journey represented the first documented direct contact between China and Europe. Emperor He also established the title of "Commander of the Xianbei" and expanded Han territory to include Qinghai Lake, bringing the empire to its greatest extent. This period of prosperity and expansion is known as the "Yongkang Prosperity" (Yongkang Zhi Long).

The Hexi Prosperity

After Emperor He's death in 105 CE, his wife Empress Deng Sui became regent for successive child emperors and ruled directly for 16 years. During her regency, known as the "Hexi Prosperity" (Hexi Sheng Zhi), she faced numerous challenges including natural disasters, foreign invasions, and internal rebellions. Empress Deng personally reduced expenses in the imperial court to provide relief for famine victims and led military campaigns to conquer the Wuhuan, Xianbei, and Southern Xiongnu, as well as to suppress pirates.

Empress Deng implemented several significant reforms. She established the "Three Generations of Prohibition" system to combat corruption, purified the official atmosphere, and ordered the collection of paper and ink throughout the country to support Cai Lun's improvements to papermaking. She also summoned the scholar Zhang衡 (Zhang Heng) to the court, where he developed the armillary sphere (hunyi) and the seismoscope (dongyi). In 119 CE, Empress Deng founded "Yuanchu Xuegong," the earliest known co-educational institution in history. She opposed superstition and dismantles improperly established shrines, stating that "ghosts and spirits are difficult to verify, and excessive sacrifices bring no fortune." These measures had a positive impact on the development of thought and culture during her reign.

The Decline under Emperor An

Empress Deng died in 121 CE, and Emperor An (Liu Huo) began personal rule. His reign marked the beginning of significant decline for the Eastern Han. Emperor An insulted and executed virtuous officials while allowing corrupt and treacherous individuals to gain power. He permitted his wet nurse, Wang Sheng, and her daughter, Bo Rong, to exercise improper influence, with Bo Rong even using imperial rituals in her arrogance. The eunuch Fan Feng conspired with Wang Sheng to depose Crown Prince Liu Bao and frame the Grand Marshal Yang Zhen, leading to widespread discontent throughout the empire.

After Emperor An's death, his wife Empress Yan became regent and installed the young Liu Yi as emperor. She eliminated the influence of the Geng clan (relatives of Empress Geng) and executed Fan Feng and Zhou Guang, but she subsequently promoted members of her own family, leading to another instance of external relatives controlling the government.

The Shun Restoration

Liu Yi died after ruling for just over 200 days. The wet nurse of Liu Bao (the deposed crown prince), Song E, collaborated with 19 eunuchs led by Sun Cheng to eliminate officials loyal to the Yan faction and restored Liu Bao to the throne as Emperor Shun. The Yan clan was subsequently executed.

Emperor Shun implemented significant reforms to restore order. In 132 CE, he adopted the suggestions of Zuo Xiong to reform the "Chaju" (recommendation) system, which was the primary method of selecting officials during this period. The "Yangjia New System" established age limits for recommendations, introduced examination mechanisms, and clarified standards for selecting talent. This reform brought the recommendation system close to what would later become the imperial examination system (keju) and marked the apex of the Chaju system, which would eventually evolve into the keju during the Sui and Tang dynasties.

During Emperor Shun's reign, scholars actively participated in governance, offering suggestions to improve local administration. For example, Yu Xu successfully advocated for the abolition of the "exoneration system" where local officials collected fines from people and claimed to use the money for relief but actually kept it for themselves. Emperor Shun's reign is considered a period of restoration, though it was ultimately unable to reverse the long-term decline of the dynasty.

The Liang Clan's Dominance

After Emperor Shun's death in 144 CE, his wife Empress Liang became regent and successively installed two child emperors (Emperor Chong and Emperor Zhi) before Emperor Huan (Liu Zhi) ascended the throne. Initially, Empress Liang appointed capable officials like Grand Marshal Li Gu and expelled all eunuchs from government, bringing temporary stability to the empire. However, she was unable to control her own family, particularly her brother Liang Ji, who reached the peak of power among imperial relatives.

Liang Ji controlled both Emperor Chong and Emperor Zhi. When the young Emperor Zhi made an inappropriate comment about him, Liang Ji had the child emperor poisoned. In 159 CE, Emperor Huan allied with eunuchs to eliminate the Liang clan, ending their dominance. However, this shift in power led to the rise of eunuch influence in government.

The Huan and Ling Eras and the Partisan Prohibitions

After eliminating the Liang clan, Emperor Huan rewarded the five eunuchs who assisted him by making them marquises, known as the "Five Marquises." This marked the beginning of eunuch political dominance. The corruption of eunuchs exceeded that of imperial relatives, leading to dissatisfaction among scholar-officials who allied with relatives to oppose them. Emperor Huan eventually demoted the Five Marquises and established China's first formal system of official avoidance known as the "Three Interchange Law" (San Hu Fa), which aimed to prevent local officials from forming cliques and curbed the power of powerful families.

Despite these measures, the conflict between eunuchs and scholar-officials intensified, leading to the first "Partisan Prohibitions" (Dang Gu) in which many officials were dismissed or imprisoned for their association with political factions.

After Emperor Huan's death, his wife Empress Dou became regent and appointed virtuous officials like Chen Fan and Dou Wu to assist her. She recruited talented scholars to serve in government and executed powerful eunuchs Su Kang and Guan Ba. However, she later allowed female attendants and eunuchs to interfere in governance, leading to chaos. Chen Fan and Dou Wu plotted to eliminate all eunuchs but were betrayed and killed, with Empress Dou being confined to the Southern Palace.

Emperor Ling (Liu Hong), who succeeded to the throne, initially executed powerful eunuchs Hou Lan and Wang Fu. He ordered the carving of the "Xiping Stone Classics," providing standardized texts of Confucian classics and promoting the development of printing technology. He also established the "Hongdu Gate School," the world's first specialized institution for literature and arts, which pioneered new developments in education.

However, Emperor Ling eventually succumbed to eunuch influence and initiated the second Partisan Prohibitions, which were only lifted after the outbreak of the Yellow Turban Rebellion in 184 CE.

Warfare and Fall

In 184 CE, the Yellow Turban Rebellion erupted across the empire. The corrupt and weakened court was unable to suppress the rebellion effectively. In desperation, the imperial court authorized regional governors to recruit their own armies, which successfully crushed the rebellion but allowed regional military commanders to consolidate power locally. In 188 CE, Liu Yan suggested that regional inspectors (cishi) be upgraded to governors (zhoumu) to better address the turmoil, creating a three-tier administrative system of province, commandery, and county. This reform strengthened regional military power and laid the groundwork for the warlordism that would dominate the late Eastern Han period.

In 189 CE, Emperor Ling died, and his young son Emperor Shao (Liu Bian) ascended the throne. The general He Jin, uncle of the new emperor, sought to eliminate the eunuch faction but faced opposition from Empress He. He Jin accepted a suggestion from the scholar-official Yuan Shao to invite the warlord Dong Zhuo to the capital to pressure the empress. However, the plot leaked, and the eunuchs preemptively killed He Jin. Yuan Shao then led his troops into the palace, massacring the eunuchs. The remaining eunuchs fled with Emperor Shao and his brother Chenliu Wang (Liu Xie), but were pursued and killed. Dong Zhuo subsequently arrived in Luoyang, gaining control of the central government.

Dong Zhuo deposed Emperor Shao and installed Chenliu Wang as Emperor Xian (Liu Xie). In 190 CE, he had Emperor Shao and Empress He executed. Dong Zhuo's tyrannical rule provoked resistance from regional warlords, who formed a coalition under Yuan Shao to oppose him. However, internal divisions within the coalition led to its failure, and Dong Zhuo maintained control of the central government. In 192 CE, the minister Wang Yun instigated Dong Zhuo's adoptive son, the warrior Lü Bu, to assassinate Dong Zhuo. However, Dong Zhuo's former subordinates Li Jue and Guo Si soon regained control, killing Wang Yun and once again plunging the court into chaos.

In 196 CE, the warlord Cao Xiong (Cao Cao) brought Emperor Xian to his capital at Xuchang, gradually consolidating imperial power in his own hands. By 220 CE, Cao Pi (Cao Cao's son) formally usurped the Han throne, establishing the state of Cao Wei with its capital at Luoyang. This marked the official end of the Eastern Han Dynasty and the beginning of the Three Kingdoms period in Chinese history.

Key Information

Cultural Significance

The Eastern Han Dynasty was a period of significant cultural and technological development. It witnessed the flourishing of Confucian scholarship with the establishment of the Imperial Academy (Taixue) and the production of standardized Confucian texts. The period also saw important technological innovations, most notably the improvement of papermaking by Cai Lun, which revolutionized record-keeping and communication.

Religiously, the Eastern Han saw the further development of Buddhism in China, with the establishment of the White Horse Temple as the first Buddhist institution. The interaction between Buddhism and native Chinese philosophical traditions like Daoism and Confucianism during this period laid the foundation for religious syncretism that would continue throughout Chinese history.

Artistically, the Eastern Han is known for its tomb art, particularly the elaborate brick reliefs and tomb figurines (mingqi) that provide valuable insights into contemporary life, beliefs, and social structures. The famous "Wu Liang Shrine" (Wu Liang Ci) in Shandong Province, with its detailed carvings of historical events, mythological scenes, and daily life, exemplifies the artistic achievements of this period.

Modern Status

Today, the Eastern Han Dynasty is remembered as a pivotal period in Chinese history that bridged the Western Han and the subsequent Three Kingdoms period. Its political institutions, cultural achievements, and technological innovations continue to influence Chinese civilization. The examination system that evolved during this period laid the foundation for China's imperial civil service system that would last for nearly two millennia.

Archaeologically, Eastern Han sites such as the tomb of the Marquis of Haihun (discovered in 2011) and numerous tombs with brick reliefs continue to provide valuable information about Han Dynasty society, culture, and technology. These archaeological findings, combined with extensive historical records, allow modern scholars to reconstruct the complex political, social, and cultural dynamics of this important dynasty.

The legacy of the Eastern Han is also evident in Chinese cultural memory, where figures like Emperor Guangwu, the scholar-officials who opposed eunuch power, and inventors like Cai Lun are celebrated as exemplars of virtue, integrity, and innovation. The dynasty's complex history of prosperity and decline, centralized authority and regional autonomy, continues to provide valuable lessons for understanding state governance and political power in historical perspective.
