Chinese Empire

The Most Famous Chinese Emperors: Power, Personality, and Legacy

Across the more than two thousand years of the Chinese empire, from 221 BCE to 1912 CE, perhaps 350 individuals held the title of emperor. Most of them are remembered, if at all, only by specialists. But a handful became so consequential — or so colourful — that their names have been household words in East Asia for centuries, and are increasingly familiar to readers worldwide. This section profiles the emperors who shaped the institution most decisively: the conqueror who invented the title, the martial ruler who made Confucianism state orthodoxy, the founder of the Tang golden age, the Ming maritime emperor, and the three great Qing rulers whose reigns defined the last dynasty of imperial China.

The emperors discussed here are arranged in roughly chronological order. Qin Shi Huang (r. 221–210 BCE) comes first, because he created the institution. Emperor Wu of Han (r. 141–87 BCE) comes next, because he gave the empire its classical form. Tang Taizong (r. 626–649) follows as the second great unifier. Yongle (r. 1403–1424) of the Ming represents the early modern maritime turn. Kangxi (r. 1661–1722), Yongzheng (r. 1722–1735), and Qianlong (r. 1735–1796) of the Qing form the last great group, ruling for 135 years and presiding over the high tide of the last dynasty. We close with brief notices of the only female emperor, Wu Zetian, and the last emperor, Puyi.

For a comprehensive treatment of the institution of the emperor, see the section on Chinese emperors and imperial power. The political mechanics of who inherited the throne are covered in imperial succession, and the world inside the palace see imperial court life. The dynastic context is set out in the section on Chinese dynasties.

Qin Shi Huang (r. 221–210 BCE): The First Emperor

The man born Ying Zheng in 259 BCE became, in 221 BCE, the first ruler in human history to claim the title of huángdì — emperor. King of the western state of Qin, he had conquered the six rival Warring States between 230 and 221 BCE in a series of swift, ruthless campaigns. Upon unification, he took the title Shi Huangdi (始皇帝), the First August Emperor, and announced that his dynasty would last “for ten thousand generations.”

His personality was a compound of immense energy, paranoid suspicion, and titanic ambition. He was a tireless administrator who read reports at all hours, an insatiable builder who commissioned palaces, roads, canals, and the first unified Great Wall, and a megalomaniac who ordered the construction of a tomb complex guarded by thousands of life-size terracotta soldiers. He toured the empire repeatedly in his last years, inscribing stone stelae on the sacred peaks to record his achievements, and he sent expeditions to find the islands of the immortals in the eastern sea. He was also a tyrant who burned books that conflicted with the state ideology in 213 BCE and reportedly buried scholars alive.

His reign transformed China. He abolished feudal fiefdoms and replaced them with commanderies and counties. He standardised the written script, the system of weights and measures, the coinage, and the axle width of carts. He built a network of imperial highways, dug irrigation canals, and connected the older northern walls into the first unified Great Wall. He expanded the empire south to the Yangzi and west into the Ordos region. Within a few years of his death in 210 BCE, the dynasty he had founded collapsed in a wave of rebellion, but the institutional framework he imposed outlasted the Qin and was inherited by every subsequent dynasty. His full story is told see our Qin Shi Huang

Emperor Wu of Han (r. 141–87 BCE): The Martial Emperor

If Qin Shi Huang invented the title of emperor, Emperor Wu of Han (漢武帝, Hàn Wǔdì) gave the institution its classical form. The seventh emperor of the Han and the son of the cautious Emperor Jing, Wu came to the throne at fifteen and reigned for fifty-four years, longer than any Han ruler. His reign was the high noon of Han power: he expanded the empire to its greatest extent, opened the Silk Road, defeated the Xiongnu nomads, and made Confucianism the state orthodoxy.

His personality combined cold intelligence, restless ambition, and a deep susceptibility to flattery. As a young man he was dazzled by the tales of the frontier general Li Guang and the legendary warriors of the steppe, and he spent most of his reign in pursuit of military glory. He sent envoys west into Central Asia to seek allies against the Xiongnu, opening the routes that would later be called the Silk Road. He conquered northern Vietnam and northern Korea, and he pushed Han influence into the Tarim Basin. His armies drove the Xiongnu far into the Mongolian steppe, and his long wars of expansion left the empire fiscally strained by the time of his death.

His most consequential decision was to elevate Confucianism above the older mixture of philosophies that had governed the early Han. In 136 BCE he established the Imperial Academy (太學, tàixué) to train scholars in the Five Classics, and from 124 BCE he reserved key offices for candidates recommended by local worthies. The Confucian classics became the basis of the civil service examination, and the scholar-official class became the backbone of imperial government. Wu’s reign was the formative moment of the imperial Chinese state, and the man himself is detailed see our Emperor Wu of Han

Tang Taizong (r. 626–649): The Perfect Emperor

Tang Taizong (唐太宗, Táng Tàizōng), personal name Li Shimin, was the second emperor of the Tang and the founder of the Tang golden age. He came to the throne through one of the most notorious events in Chinese history: the Xuanwu Gate Incident of 626, in which he ambushed and killed his elder brother Li Jiancheng and the latter’s allies, then forced his father Li Yuan (Emperor Gaozu) to abdicate. Despite the bloody start to his reign, Taizong proved to be one of the most brilliant, reflective, and successful rulers in Chinese history. The phrase “Taizong’s reign” (貞觀之治, Zhēnguàn zhī zhì) became a byword for good government.

Taizong was a great soldier, a great general, and a great judge of men. He defeated the Eastern Turks in 630, taking control of the steppe routes and being acclaimed by the steppe peoples as “Heavenly Khan.” He supervised the compilation of legal codes that became the model for East Asian jurisprudence. He listened to remonstrance: when his famously outspoken chancellor Wei Zheng corrected him in public, Taizong would bow and thank him, even when the criticism stung. He made the Tang government the most meritocratic and effective in the world, and he presided over a flourishing of poetry, painting, and sculpture.

The Xuanwu Gate Incident of 626, in which Taizong ambushed and killed his elder brother Li Jiancheng and the latter’s allies at the northern gate of the Taiji Palace, and then forced his father Li Yuan to abdicate, haunted Taizong for the rest of his life. He was determined to leave a record of legitimate, benevolent rule, and he succeeded. Tang Taizong became, in later Chinese tradition, the model emperor: a brilliant unifier, a patron of arts and learning, a general who led his armies, and a ruler who listened to honest counsel. The Confucian historiographers of the Song and after ranked him, with Emperor Wen of Han, as one of the two great virtuous rulers.

Yongle Emperor of the Ming (r. 1403–1424): The Maritime Emperor

The third emperor of the Ming, Yongle (永樂, Yǒnglè), personal name Zhu Di, was the most energetic and ambitious of the early Ming rulers and one of the most controversial. He was the fourth son of the Hongwu emperor, the founder of the Ming, and he came to the throne by launching a three-year civil war against the designated heir, his nephew the Jianwen emperor, whom he eventually defeated and whose supporters he slaughtered in a great purge. Once enthroned, however, Yongle proved to be a brilliant administrator and a great patron of culture and exploration.

Yongle is best known for two enormous projects. The first was the Zheng He treasure voyages: between 1405 and 1433, the eunuch admiral Zheng He led seven great expeditions into the Indian Ocean, reaching as far as East Africa, the Persian Gulf, and possibly the southern tip of the African continent. The fleets numbered up to 300 ships and 30,000 men, dwarfing anything contemporary Europe could put to sea. The second project was the construction of the Forbidden City in Beijing, completed in 1420 and still the largest palace complex in the world. Yongle also moved the Ming capital from Nanjing to Beijing, rebuilt the Great Wall in brick and stone, and compiled the Yongle Encyclopedia, the largest encyclopaedia of the premodern world.

Yongle’s personality combined the ruthlessness of a usurper with the cultural ambitions of a Confucian monarch. He was a great reader, a fine calligrapher, and a devout Buddhist who patronised Tibetan lamas. He was also, in his early years, a cold and decisive soldier who personally led armies into Mongolia on five major campaigns. He died in 1424 on campaign in the north, after falling from his horse. His reign, brief and violent as it was, set the political and cultural template of the Ming.

Kangxi (r. 1661–1722): The Long Reign

The longest-reigning emperor in Chinese history, the Kangxi emperor (康熙帝, Kāngxī dì), personal name Xuanye, took the throne at the age of seven in 1661 and reigned for sixty-one years, until his death in 1722. He was the fourth emperor of the Qing and the second to rule over all of China. His reign was one of the most consequential in Chinese history: he suppressed the revolt of the Three Feudatories (1673–1681), conquered Taiwan (1683), campaigned against the Russians on the Amur (1685–1689), and incorporated Mongolia, Tibet, and Xinjiang into the empire for the first time.

Kangxi’s personality combined intellectual curiosity, physical energy, and a sharp political instinct. He was a fine scholar of the Confucian classics, an accomplished calligrapher, and an avid student of Western science — he took lessons in geometry, astronomy, and anatomy from the Jesuit missionaries at court, and he gave the Jesuits permission to translate the Elements of Euclid into Chinese. He was a tireless traveller who made six inspection tours of the south and repeatedly visited the summer retreat at Chengde. Kangxi also presided over one of the most serious succession crises in Chinese history. He had fathered thirty-five sons, and the question of who would inherit was unresolved for decades. The controversy is see our how Chinese emperors were chosen.

Yongzheng (r. 1722–1735): The Working Emperor

Yongzheng (雍正, Yōngzhèng), personal name Yinzhen, was the fourth son of Kangxi and the fifth emperor of the Qing. He succeeded his father after a contested transition, and he reigned for only thirteen years, but the period was one of the most hard-working and effective in Qing history. Yongzheng is remembered for two things above all: an intense personal involvement in government, and a thorough reform of the bureaucracy and the tax system.

Yongzheng reportedly worked sixteen to eighteen hours a day, reviewing memorials, drafting responses in his own hand, and following up on local problems. He abolished the surcharges that had accumulated under the late Kangxi reign, instituted a policy of “melting the official surcharges into the regular tax” (耗羨歸公, hàoxiān guīgōng), which raised state revenue and reduced corruption. He reorganised the Grand Council and the system of palace memorials, and he tightened discipline throughout the bureaucracy. He was also famously suspicious: he is said to have kept a private list of those he considered enemies, and to have ordered the execution or exile of several brothers and high officials. Yongzheng’s personality was austere, shrewd, and intensely disciplined. The reforms he instituted left the state in strong fiscal shape, and his son Qianlong inherited a state that was the wealthiest and most populous on earth.

Qianlong (r. 1735–1796): The Imperial Magnificence

The Qianlong emperor (乾隆帝, Qiánlóng dì), personal name Hongli, was the fourth son of Yongzheng and the sixth emperor of the Qing. He reigned for sixty years, voluntarily abdicating in 1796 out of deference to the tradition that no emperor should reign longer than his grandfather Kangxi, and he lived on as Retired Emperor until 1799. His reign was the high tide of the Qing and the most splendid in late imperial Chinese history. It was also the moment at which the long Qing boom began to exhaust itself.

Qianlong was a cultivated, energetic, and self-confident ruler. He was a fine poet, a competent painter, a passionate collector, and a great patron of the arts. He patronised the compilation of the Siku Quanshu (四庫全書, Complete Library of the Four Treasuries), the largest collection of books in Chinese history, and he presided over the great imperial collection of paintings and calligraphy. He expanded the empire to its greatest territorial extent, completing the conquest of Xinjiang in 1759 and incorporating Tibet, Mongolia, and parts of Central Asia. He made ten grand inspection tours of the south, repeating his grandfather Kangxi’s travels.

The Qianlong reign was also the period of the most damaging corruption in Qing history. The eunuch-style favourite Heshen dominated the court for twenty years, amassing a fortune that, by some accounts, equalled half the state revenue. The long peace and rising population masked serious structural problems: fiscal pressure on the peasantry, ethnic tensions in the western and southern frontiers, and the corrosive effect of a state apparatus that was no longer reformed. The Qianlong reign, in retrospect, marked the high point of the imperial system and the beginning of its long decline.

Other Notable Emperors

Wu Zetian (r. 690–705): The Only Female Emperor

The only woman in Chinese history to rule as emperor regnant, Wu Zetian (武則天) entered the palace of Emperor Taizong as a low-ranking concubine in the 620s, transferred to the household of his son and successor Emperor Gaozong, and gradually accumulated power as Gaozong’s health declined. After Gaozong’s death in 683, she ruled as regent for her sons, and in 690 she proclaimed a new Zhou Dynasty (周) and took the title of emperor. She reigned for fifteen years in her own name, and even after her forced abdication in 705 she continued to exert influence at court. Modern scholarship has rehabilitated her reputation as a competent ruler who maintained the empire’s strength, patronised Buddhist scholarship, and made a successful transfer of power. Her story is one of the most remarkable in Chinese history, and it is see our the role of the empress dowager.

Hongwu (r. 1368–1398): The Rebel Founder

The founder of the Ming, Hongwu (洪武, Hóngwǔ), personal name Zhu Yuanzhang, was born a peasant, lost his family in a famine, became a Buddhist monk, joined a rebel band, and eventually rose to command the army that expelled the Mongols. His reign was one of the most thorough reorganisations of the state in Chinese history. He abolished the chancellor’s office, divided the empire into military-administrative regions under his relatives, and instituted a draconian legal code that prescribed death for dozens of offences. He also executed the chancellor Hu Weiyong and ten thousand of his associates in 1380 in one of the largest political purges in history.

Puyi (r. 1908–1912): The Last Emperor

The last emperor of China, Puyi (溥儀, Pǔyí), was born in 1906, enthroned in 1908 at the age of two, and forced to abdicate in February 1912. He lived on in the Forbidden City as a kind of puppet emperor until expelled in 1924, became the puppet ruler of Japanese-occupied Manchukuo in the 1930s and 1940s, was captured by the Soviets in 1945, returned to China in 1959, and worked in a botanical garden until his death in 1967. His reign marked the end of the imperial institution in China.
