Ancient China

For more than three thousand years there has been a civilization in the valleys of the Yellow and Yangtze rivers that has thought of itself as the center of the world. Its people called their land Zhongguo—the "Middle Kingdom," the country at the center of all under Heaven. Dynasties rose and fell; conquerors came and were absorbed; capitals moved and borders breathed in and out. Yet a single continuous thread of writing, ritual, and statecraft ran through it all, making Chinese civilization the longest continuous one on Earth.

To tell its story honestly, we must begin by separating two things that are often blurred: legend and evidence. The Chinese tradition remembers a golden dawn of sage-rulers—the Three Sovereigns and Five Emperors, the Yellow Emperor who supposedly invented the arts of civilization, the great Yu who tamed the floods. These are cherished myths, not history. No archaeology confirms them. We should treat them as the founding stories a culture tells about itself: beautiful and meaningful, but not documented fact.

The first dynasty in the traditional list, the Xia, sits in a gray zone. Histories written centuries later describe it in detail, and archaeologists have found an impressive Bronze Age culture—often linked to the site of Erlitou—that flourished at roughly the right time and place. But nothing yet unearthed can be firmly labeled "Xia," and that culture left no readable writing about itself. So the Xia remains debated: possibly real, possibly a later idealization. Honest history flags it rather than assuming it. It is with the Shang—whose kings' names were later confirmed by inscriptions pulled from the ground—that documented China truly begins.

One idea, more than any other, would give Chinese history its rhythm. It was the doctrine of the Mandate of Heaven—the belief that Heaven grants a just ruler the right to reign and withdraws it from a tyrant, whose fall then becomes not merely a defeat but a cosmic verdict. It explained why dynasties rose and fell, licensed rebellion against bad rulers, and demanded virtue from good ones. We will meet it properly in the next chapter, at the very moment it was born.

This is the story of how a scatter of Bronze Age settlements became an empire that would endure, in one form or another, for more than two thousand years—and of the philosophers, emperors, inventors, and rebels who made it. It begins with writing scratched onto bone.

Documented Chinese history opens, strangely, in a nineteenth-century pharmacy. For generations, farmers near Anyang had been turning up old bones and shells, which apothecaries ground into medicine as "dragon bones." In 1899 scholars noticed that many carried mysterious scratches—and realized, with astonishment, that they were reading the oldest Chinese writing ever found: the oracle bones of the Shang dynasty, more than three thousand years old.

The Shang kings ruled the Yellow River heartland from roughly 1600 to 1046 BCE. To divine the future, their diviners applied heat to turtle shells and ox shoulder blades until they cracked, then read the cracks as answers from the ancestors and the high god Di. They inscribed the questions onto the bone—about harvests, war, childbirth, the weather, the king's aching tooth. Tens of thousands of these inscriptions survive, and they do something remarkable: they confirm, name by name, a list of Shang kings that later Chinese historians had written down, proving those records reliable all the way back into the Bronze Age.

The writing on those bones is already mature—thousands of characters, recognizably the ancestor of the script Chinese people write today. A system that developed must have had earlier roots we have not yet found. That unbroken line of characters, running from the oracle bones to the modern newspaper, is one of the marvels of human culture: no other living script reaches back so far.

Around 1046 BCE the Shang fell to a vassal people from the west, the Zhou, at the Battle of Muye. Now the conquerors faced a problem of legitimacy. How could they justify overthrowing a dynasty that had claimed the favor of Heaven and the ancestors? Their answer was one of the most consequential ideas in Chinese history. The last Shang king, they declared, had become a debauched tyrant; Heaven had therefore stripped him of the right to rule and bestowed it upon the virtuous Zhou. This was the Mandate of Heaven.

The Mandate was a double-edged gift. It made every ruler's success proof of virtue—and every disaster, be it flood, famine, or defeat, a possible sign that Heaven was withdrawing its favor. It gave rebels a license and gave kings a warning. For the next three thousand years, Chinese thinkers would judge every dynasty by it, and every founder of a new dynasty would claim it.

The Zhou became the longest dynasty in Chinese history, reigning in name from 1046 to 256 BCE—nearly eight centuries—though for much of that time their kings were figureheads. In 771 BCE the western capital was sacked, a king was killed, and the court fled east, beginning the era historians call the Eastern Zhou. Real power drained away to a patchwork of regional lords who warred among themselves. Yet out of that lengthening chaos came the greatest flowering of thought China would ever know.

It is one of history's paradoxes that China's most violent age produced its wisest books. As Zhou authority dissolved and rival states fought for survival—first through the Spring and Autumn period, then the aptly named Warring States—wandering thinkers moved from court to court, each offering rulers a cure for the chaos. Their competing answers became known as the Hundred Schools of Thought, and several of them would shape East Asia forever.

The greatest of these thinkers was Confucius (Kongzi, 551–479 BCE), a minor official and teacher from the state of Lu who never won the high office he sought. His answer to the chaos was not law or force but virtue, ritual, and right relationships—between ruler and subject, parent and child, husband and wife, elder and younger, friend and friend. If everyone cultivated character and played their proper role with sincerity, he taught, harmony would follow naturally. His conversations, collected by his disciples in the Analects, became the ethical foundation of a civilization.

Where Confucius looked to society, the Daoists looked to nature. The Dao De Jing, attributed to the sage Laozi—who may himself be legendary, though the book is real and ancient—taught almost the opposite lesson: that the harder one grasps and strives, the worse things go. Wisdom lies in aligning oneself with the Dao, the natural "Way" of the universe, and in wu wei—effortless action, accomplishing by not forcing. Daoism became the poetic, mystical counterweight to Confucian duty, and the two would balance each other in the Chinese soul ever after.

A third school gave the opposite answer to Confucius. The Legalists—thinkers such as Han Fei and the reforming statesman Shang Yang—argued that human nature was fundamentally selfish, and that only strict laws, harsh punishments, and a powerful, centralized state could produce order. Not virtue but fear; not the cultivated gentleman but the efficient machine. It was a cold and effective doctrine, and it was about to build the first empire—and very nearly wreck it.

The age of war produced one more classic. In the state of Wu, a treatise on strategy appeared that is still read in military academies and boardrooms today: The Art of War, traditionally attributed to the general Sun Tzu (Sunzi). Its date and authorship are debated—some scholars think it was compiled later—but its wisdom is timeless: that the supreme skill is to win without fighting, and that victory begins with knowledge.

These schools were never idle philosophy. They were rival prescriptions for ending an age of blood. In the end all three great currents survived and braided together: Confucianism became the public ethic of family and state, Daoism the private balance of the individual, and Legalism the hidden machinery of imperial power. The next chapter belongs to the men who embraced Legalism, sharpened one western state into a weapon, and conquered everything under Heaven.

In 221 BCE, after centuries of warfare, one state swallowed all the others. The western state of Qin, forged into a ruthless war-machine by generations of Legalist reform, conquered its rivals one by one until its king ruled everything under Heaven. No mere king's title could contain the achievement, so he invented a grander one: Huangdi, "Emperor." He would be Qin Shi Huang—First Emperor of Qin. For the first time in its history, China was a single empire.

The man born Ying Zheng had become king of Qin as a boy of thirteen; by thirty-eight he had unified the known world. Now he set about making the conquest permanent. With his chancellor Li Si, he abolished the old feudal states and divided the empire into administered provinces run by appointed officials. He standardized almost everything: one script, one currency, one system of weights and measures, even the axle-width of carts so that every wheel would fit the same ruts in the road. A merchant or magistrate could now travel from one end of the empire to the other and be understood.

Of all these acts, the standardization of writing was the deepest. China's spoken tongues differed enormously from region to region—and still do—but a single script meant a text written in one place could be read across the entire civilization. That unity of writing has held China together through every subsequent conquest, division, and collapse. It may be the single most important thing the First Emperor ever did.

The price was terror. Legalism in power meant forced labor on a colossal scale. The emperor conscripted hundreds of thousands to build roads and canals, and to join and extend the older frontier ramparts of the northern states into an early version of the Great Wall against the steppe nomads. Countless laborers died at the works. To crush dissent, he is said to have ordered the burning of books that could nourish criticism—Confucian and historical texts above all—and, according to the historian Sima Qian, to have had scholars executed. To later Confucians this "burning of the books and burying of the scholars" made him the archetype of the tyrant, though some modern historians suspect the scale was exaggerated by the hostile writers who came after him.

Qin Shi Huang died in 210 BCE—reportedly while touring in search of that elixir, perhaps hastened to his grave by mercury pills his physicians prescribed for long life. He had boasted that his dynasty would endure for ten thousand generations. It lasted barely four years after him, disintegrating into revolt by 206 BCE, the shortest-lived of all the great dynasties. Its Legalist harshness had built an empire and then broken upon its own cruelty. But the unified China it had created never truly went away—every later dynasty would rule the state the First Emperor made.

Out of the Qin collapse rose a commoner. Liu Bang, a man of humble birth and rough manners, defeated his rivals in the wars that followed and in 202 BCE founded the Han dynasty. It would become China's classical golden age—so defining that, more than two thousand years later, the great majority of Chinese still call themselves the "Han people," and their language "Han speech" (Hanyu). To be Chinese, ethnically, is to this day to be Han.

The Han kept the unified state the Qin had built but softened its cruelty. Where the Qin had ruled by terror, the Han gradually embraced Confucianism, marrying the gentle Confucian ideals of virtue and learning to the strong central bureaucracy the Legalists had forged. Under Emperor Wu (Han Wudi, r. 141–87 BCE), Confucianism became the official ideology of the state, and the empire expanded dramatically—south toward Vietnam, north against the Xiongnu nomads, and west into the oases of Central Asia.

It was under the Han that one of China's great gifts to the art of government first took root: the ideal that officials should be chosen for learning and merit—recommended, and tested on the Confucian classics—rather than for birth alone. Fully realized only centuries later, this civil-service ideal would become one of the most influential institutions in world history. The state, the Han believed, should be run by educated men of character.

Emperor Wu also sent an envoy, Zhang Qian, on a desperate mission west to seek allies against the Xiongnu. Zhang was captured, held for years, escaped, and finally returned with something more valuable than any alliance: knowledge of the roads and kingdoms of the west. The routes he charted became the Silk Road, the caravan network linking China to Central Asia, India, Persia, and ultimately Rome.

At its height the Han was one of the two great empires of antiquity, rivaling the Roman Empire at the other end of Eurasia in size and population—each perhaps 50 to 60 million people, though such ancient figures are estimates. It was the Han, too, that produced China's greatest historian, Sima Qian, whose Records of the Grand Historian became the model for all later Chinese history-writing. He had fallen foul of the emperor, and chose a terrible mutilation over an honorable death so that he might live to finish his work.

The Han reigned for four centuries, briefly interrupted when the usurper Wang Mang seized the throne (9–23 CE), splitting the dynasty into a Former and a Later Han. But its golden age slowly decayed, eaten by court intrigue, the corruption of palace eunuchs, and finally a vast peasant uprising, the Yellow Turban Rebellion of 184 CE. By 220 CE the Han collapsed into three warring kingdoms. Yet it had set the enduring template for everything after: a Confucian, bureaucratic empire, unified under one Son of Heaven, that every later dynasty would strive to restore.

Before the Han fell, it gave the world a gift as quiet as it was world-changing: paper. The court official Cai Lun is traditionally credited, around 105 CE, with perfecting a method of making paper from tree bark, hemp, and rags. Forms of paper had existed a little earlier, but Cai Lun's process made it cheap and practical for the first time. Lighter than the bamboo strips scholars had bound into bulky scrolls, and far cheaper than silk, paper would eventually carry human knowledge across the entire world.

Paper was not the Han's only invention. Chinese craftsmen produced an early magnetic compass—a lodestone "south-pointer" first used not for navigation but for divination and aligning buildings with cosmic forces. The polymath Zhang Heng built a bronze seismoscope in 132 CE that could register the direction of a distant earthquake. The Han also advanced cast iron, medicine, mathematics, and astronomy, ranking it among the most inventive civilizations of the ancient world.

But the fall of the Han opened one of the most famous and romanticized eras in all of Chinese history: the Three Kingdoms. From 220 CE, three states—Wei in the north, Shu in the west, and Wu in the southeast—fought one another for the Mandate of Heaven. It was an age of warlords and cunning ministers, of shifting alliances and brilliant stratagems, of loyalty and betrayal played out on a grand stage.

Militarily, the period was a bloody stalemate that lasted only about sixty years and coincided with a catastrophic fall in China's registered population—the result of war, mass migration, and the simple breakdown of census-taking as central authority collapsed. Yet no era of Chinese history is more beloved, because more than a thousand years later it became the raw material for one of the "Four Great Classical Novels": Romance of the Three Kingdoms, a sprawling historical epic written in the Ming dynasty and traditionally attributed to Luo Guanzhong.

The Three Kingdoms ended in 280 CE, when the Jin dynasty briefly reunited China under one throne. But the reunion was fragile and short-lived. Within a few decades the country shattered again—and this time it would stay broken for nearly three centuries. Into that long division, along the very Silk Road the Han had opened, a foreign religion from India was already walking, and it would change the Chinese soul.

For nearly three hundred years after the Han, China was divided. In the north, dynasty after dynasty was founded by nomadic conquerors from the steppe who settled down and slowly became Chinese; in the south, refugee courts of the old aristocracy carried on the classical traditions. Historians call this fractured age the Northern and Southern Dynasties. It was politically unstable and often violent—yet division did not mean darkness. Art, poetry, and above all religion flourished.

The great story of these centuries is the arrival of Buddhism. Born in India, the faith travelled the Silk Road into China, offering what the native traditions did not: a path of personal salvation, an explanation for suffering, a promise of rebirth, monasteries where one could withdraw from the world, and a message of compassion for all living things. In an age of war and short, uncertain lives, it spread explosively—among peasants and emperors alike. Devoted Chinese pilgrims such as Faxian journeyed all the way to India and back to bring home the scriptures.

Buddhism did not sweep the old teachings away. Over time it blended with them into the characteristic Chinese pattern of the "three teachings"—Confucianism for the public duties of family and state, Daoism for harmony with nature, and Buddhism for the fate of the soul—each answering a different human need. But its coming was the single greatest cultural importation in Chinese history before the modern age.

Reunification, when it came, came suddenly. In 581 CE a northern general named Yang Jian seized power, and by 589 he had conquered the south and reunited China after nearly three centuries of division, founding the Sui dynasty. As Emperor Wen, he rebuilt strong central government, restored the bureaucracy, and revived the idea of recruiting officials by examination.

But the Sui, like the Qin eight centuries before it, drove its people too hard. The second emperor, Yang Guang, exhausted the country with grandiose building projects and a series of disastrous invasions of Korea. Revolts erupted across the empire, and in 618 he was assassinated. The Sui had lasted barely thirty-seven years. Yet, exactly like the Qin, this short and brutal dynasty had done the essential work of reunification—and it handed a rebuilt, reconnected empire to one of the most glorious dynasties in the history of the world: the Tang.

For nearly three centuries the Tang dynasty presided over what many historians consider the most brilliant civilization then on Earth. Its capital, Chang'an—modern Xi'an—was the largest and most cosmopolitan city in the world, home to perhaps a million people, its markets thronged with Persian merchants, Central Asian musicians, Turkic soldiers, Korean students, and pilgrims of a dozen faiths. Confident, open, and immensely powerful, Tang China set a standard of culture that Korea, Japan, and Vietnam raced to imitate.

The early Tang under Emperor Taizong (Li Shimin, r. 626–649) is remembered as a model reign—an era of expansion, competent administration, and a ruler who famously prized honest criticism from his ministers. The examination system was revived and strengthened. Tang armies pushed far into Central Asia, and the dynasty's power and prestige reached a zenith rarely matched before or since.

It was in this era that the most extraordinary figure in the whole of imperial politics rose to the top. Wu Zetian entered the palace as a low-ranking consort, climbed through the treacherous ranks of the court, ruled effectively from behind two weak emperors, and then, in 690, did the unthinkable: she declared herself huangdi—emperor—in her own name. She remains the only woman in more than two thousand years of imperial history to hold that supreme title in her own right.

The Tang was also the golden age of Chinese poetry. Two poets tower above all the rest: Li Bai (701–762), the exuberant, wine-loving romantic who wrote of moonlight and freedom, and Du Fu (712–770), the sober conscience of a war-torn age who wrote of suffering and duty. Their verse is memorized by Chinese schoolchildren to this day; Li Bai's short poem on gazing at the bright moon and thinking of home is perhaps the most famous poem in the language. Their words are quoted so often, and translated so variously, that they have become part of the very texture of Chinese culture.

Then came the catastrophe. In 755 a favored frontier general named An Lushan launched a massive rebellion that tore the empire apart. The An Lushan Rebellion (755–763) is remembered as one of the most destructive events in premodern history—though the numbers demand caution.

The dynasty staggered on for another century and a half, hollowed out by provincial warlords, palace eunuchs, and recurring revolt, until it finally fell in 907. China dissolved once more into an era of division—the Five Dynasties and Ten Kingdoms. But this interregnum would be brief. Within decades a new dynasty would reunite the land and launch it into a burst of invention that would, in time, remake the entire world.

In 960 a general named Zhao Kuangyin reunited the Chinese heartland and founded the Song dynasty. The Song would be militarily weaker than the Tang—it lost the north to nomadic empires and eventually the whole country to the Mongols—yet in almost every other respect it was one of the most advanced societies the world had ever seen. Historians sometimes describe the Song as an economic and technological revolution: many of the ingredients of an industrial revolution, assembled seven centuries early.

It was under the Song that the innovations traditionally called China's greatest came together and transformed. Gunpowder, discovered by Tang alchemists who had ironically been searching for an elixir of immortality, the Song turned into war—bombs, rockets, and "fire-lances," the distant ancestors of the gun. Printing reached new heights: woodblock printing already existed (the Diamond Sutra of 868 CE is the world's oldest dated printed book), but around the 1040s a commoner named Bi Sheng invented movable type, four centuries before Gutenberg. The magnetic compass was now turned to navigation, letting ships sail confidently out of sight of land.

The Song economy boomed so mightily that it outran the supply of metal coins—so the government issued the world's first state-backed paper money. Iron and coal production reached levels Europe would not match for another six or seven centuries. And the cities exploded into something the world had never quite seen before.

This was an age of high thought as well as high commerce. The philosopher Zhu Xi and his fellow thinkers reinterpreted the Confucian classics into a rigorous new system—Neo-Confucianism—that would dominate Chinese intellectual life until the twentieth century. Landscape painting reached a sublime, meditative height, and the polymath Shen Kuo wrote with startling clarity of magnetic declination, geology, and the movements of the heavens.

But the Song lived always under military threat. In 1127 it lost the north to the Jurchen Jin; the court fled south and rebuilt itself at Hangzhou as the Southern Song—prosperous, cultured, and hemmed in. And far beyond the horizon, on the Mongolian steppe, a far greater storm was gathering. In 1279 the Song became the last and hardest conquest of the Mongols. The most sophisticated society on Earth had fallen to the most formidable army the world had ever produced.

How do you govern a vast empire without a hereditary nobility seizing all the power for itself? China's answer became one of its most distinctive and influential institutions: the imperial examination. From the Sui and Tang onward, and above all under the Song and the dynasties that followed, the men who governed China were chosen—at least in principle—not by birth but by their mastery of the Confucian classics, tested in grueling written examinations.

The system was punishing. A candidate might study for decades, memorizing the classics and the approved commentaries, before sitting for examinations held at the local, provincial, and finally the palace level. Candidates were sealed for days into tiny cells to write their essays, watched against cheating. The tiny fraction who passed the highest, empire-wide degree—the jinshi—could enter the bureaucracy and rise toward the summit of power. These scholar-officials, whom Westerners would later call "mandarins," ran the largest state on Earth.

For its time, it was a startlingly meritocratic idea: that talent and learning, not blood or birth, should confer power. In principle a poor peasant's brilliant son might rise to become a minister of state—and a handful actually did, celebrated forever after in local memory. The system gave China a professional, literate governing class bound together by a shared canon and a shared ethic, and it lent the empire a remarkable stability and continuity across the centuries, holding it together even when dynasties fell.

But the limits were just as real. Preparing for the exams required years of leisure and expensive tutoring that only comfortable families could afford, so in practice the landed gentry dominated the results. And the curriculum, over time, grew rigid. By the Ming and Qing it demanded a stylized "eight-legged essay" on set classical passages, rewarding elegant conformity and rote mastery over originality. Critics charged that it trained superb memorizers rather than innovators, and that its reverence for ancient texts left the governing class dangerously inflexible when a new and modern world came knocking.

Still, for thirteen centuries the examination hall shaped China. It created the enduring ideal of the scholar-official—the cultivated gentleman who could write poetry, paint a landscape, and administer a province with equal grace—and it embedded a reverence for education so deep that it survives across Chinese societies to this day. When the system was finally abolished in 1905, it was a sign that the old imperial order itself was passing away.

In the thirteenth century the most formidable military force in history erupted from the steppe. The Mongols, united by Genghis Khan, conquered the largest contiguous land empire the world has ever known—and China was their greatest prize. It took decades of ferocious war, but by 1279 Genghis's grandson Kublai Khan had subdued the last resistance of the Southern Song. For the first time, all of China lay under the rule of a foreign conqueror. (The Mongol side of this story—the rise of Genghis, the world empire, the conquests—is told in full in our companion narrative on the Mongol Empire.)

Kublai declared himself emperor of a new dynasty, the Yuan, in 1271, moving his capital to Dadu—the city we now call Beijing. He was a Mongol who chose to rule China as a Chinese-style emperor, adopting much of its administration and ceremony. Yet he and his successors kept Mongols and their foreign allies firmly at the top of a rigid ethnic hierarchy that placed the native Chinese—especially the recently conquered southerners—at the very bottom.

Under the single vast canopy of the Mongol Empire, the Silk Road grew safer than it had ever been, and trade and travel across Eurasia flourished—the era historians call the Pax Mongolica. It was to Kublai's China, by his own account, that a young Venetian merchant came and stayed for years: Marco Polo, whose book would dazzle all of Europe.

Yet the Yuan sat on unstable ground: a small Mongol minority ruling an immense Chinese majority. Resentment of ethnic discrimination and heavy taxation festered, and the Mongols never fully won over the Confucian scholar class, having suspended and downgraded the beloved examinations for decades. Then, in the fourteenth century, calamity piled on calamity—the Yellow River flooded catastrophically, famine spread, and plague swept through (the same Black Death then ravaging Eurasia). To a people schooled in the Mandate of Heaven, such disasters could mean only one thing: Heaven was withdrawing its favor.

Rebellion spread like fire across the land. Out of the chaos rose a man born into the poorest of peasant families, orphaned by famine, who had once begged as a wandering monk: Zhu Yuanzhang. He built a rebel army, drove the Mongols back to the steppe, and in 1368 proclaimed a new, native Chinese dynasty. The Yuan had lasted less than a century. Han Chinese rule was restored—and the new dynasty, the Ming, was fiercely determined that China would never again fall to outsiders.

Zhu Yuanzhang, who had risen from beggar to emperor, founded the Ming ("Brilliant") dynasty in 1368 and took the reign name Hongwu. Having survived famine and lived under Mongol misrule, he was determined to restore a proud, orthodox, native Chinese order—and to rule it with an iron grip, purging officials by the thousands whenever he suspected disloyalty. The Ming would reign for nearly three centuries and bequeath to the world some of the most iconic images of imperial China.

Under his son, the Yongle Emperor (Zhu Di, r. 1402–1424), the Ming reached a peak of confidence and ambition. He moved the capital north to Beijing and built there the palace complex that has symbolized Chinese emperorship ever since: the Forbidden City.

The Yongle Emperor also launched one of the most astonishing episodes in the history of the sea. Between 1405 and 1433, the admiral Zheng He—a Muslim court eunuch of great ability—led seven immense voyages across the Indian Ocean, reaching Southeast Asia, India, Arabia, and the coast of East Africa. His "treasure fleets" were staggering in scale, dwarfing anything Europe would put to sea for another century.

And then, astonishingly, China turned its back on the ocean. After 1433 the voyages simply stopped. The Confucian officials who distrusted the powerful eunuchs, and who saw little value in costly foreign adventures, won the argument at court. The great fleets were left to rot at their moorings, ocean-going shipbuilding was restricted, and China deliberately turned inward—at the very moment Europe was about to turn outward toward the sea.

The later Ming turned its energy landward, rebuilding and extending the northern frontier defenses into the Great Wall the world pictures today. But walls could not save the dynasty from itself. Court intrigue, the tyranny of palace eunuchs, fiscal crisis, and a run of famines hollowed it out from within. In 1644 a peasant rebel army seized Beijing, and the last Ming emperor hanged himself from a tree on a hill behind the Forbidden City. Into the chaos, from beyond the wall, rode a new power.

The power beyond the wall was the Manchus—a people from the forests of the northeast, descendants of the same Jurchens who had once wrenched northern China from the Song. Organized into disciplined military "banners," they had already built a formidable state of their own. When rebellion toppled the Ming in 1644, a Ming general guarding the strategic pass at Shanhaiguan opened the gate and invited the Manchus in to help him crush the rebels. They crushed them—and then they stayed, founding the Qing dynasty, the last imperial dynasty in Chinese history.

Once again a tiny minority ruled the vast Han Chinese majority. To mark their dominance, the Manchus forced Chinese men to shave their foreheads and wear the hair in the Manchu queue, the long braid, on pain of death—"lose your hair or lose your head." Yet they also ruled as thoroughly Confucian emperors, preserving the examinations and the scholar-bureaucracy and courting the loyalty of the educated class. It took decades to complete the conquest, but the Qing would become one of the most successful dynasties China ever knew.

The high Qing rested on two of the longest-reigning monarchs in all of world history: the Kangxi Emperor (r. 1661–1722) and his grandson the Qianlong Emperor (r. 1735–1796). Under them China swelled to its greatest territorial extent, roughly doubling in size as it absorbed Mongolia, Tibet, Xinjiang, and Taiwan, while its population exploded past three hundred million. For a time it was the largest, and among the most prosperous, empires on Earth.

The Qing presided over a golden age of population growth, commerce, and culture. It produced the greatest of all Chinese novels, Dream of the Red Chamber; monumental scholarly encyclopedias; and fine porcelain traded to every corner of the globe. European demand for Chinese tea, silk, and porcelain poured a river of silver into the empire, which seemed magnificently self-sufficient—the center of the world, in need of nothing from anyone.

That serene confidence was about to curdle into a fatal blindness. Even as Qianlong was waving away British trinkets, the world beyond China was transforming. Europe was industrializing; its warships and its factories were racing ahead. The Qing empire was vast, populous, and proud—and, though almost no one at court could see it, falling dangerously behind. Within half a century of Qianlong's death, the modern world would come crashing through China's door, and the last dynasty would begin its long descent into humiliation.

In the early nineteenth century, Britain had a problem. It craved Chinese tea, but China wanted almost nothing Britain made, and British silver was draining east to pay for the trade. British merchants found a solution as profitable as it was monstrous: opium, grown in British-ruled India and smuggled into China in ever-larger quantities. By the 1830s millions of Chinese were addicted, the flow of silver had reversed, and the Qing government moved at last to stamp the traffic out.

In 1839 the emperor dispatched an upright, incorruptible official named Lin Zexu to Canton (Guangzhou). Lin seized and destroyed some twenty thousand chests of British opium and blockaded the foreign traders in their factories. Britain—its merchants howling for compensation and its government cloaking the drug trade in the language of "free trade"—answered with war.

It did not end there. A Second Opium War (1856–1860), waged by Britain and France together, wrung still more concessions from the dynasty—more open ports, the legalization of opium, foreign diplomats resident in Beijing itself. And in 1860, to punish the Qing, Anglo-French troops looted and burned the Old Summer Palace, the exquisite imperial garden-palace outside Beijing—an act of cultural destruction still remembered with bitterness in China today.

And while the foreigners pressed in from the coast, the Qing was very nearly destroyed from within—by the deadliest civil war in the whole of human history. Its leader was Hong Xiuquan, a failed examination candidate who, after a series of visions, became convinced that he was the younger brother of Jesus Christ, sent by God to establish a "Heavenly Kingdom of Great Peace"—the Taiping Tianguo. His movement swept across southern China, seized a vast territory, and held its capital at Nanjing for more than a decade.

The Taiping was finally defeated in 1864, amid staggering bloodshed. The Qing survived—but it had been shaken to its foundations, and saved partly by regional Chinese armies whose commanders now held real, independent power. The dynasty tried to reform and "self-strengthen," building arsenals and shipyards and buying modern guns, but it proved far too little against the rising tide of foreign power and internal decay. A shattering defeat by Japan in 1895—an Asian neighbor the Chinese had long looked down upon—drove the lesson home. The Mandate of Heaven, it seemed, was slipping from Qing hands.

By 1900 China was a wounded giant—its coast carved into foreign spheres of influence, its government weak and repeatedly humiliated, its people seething. That fury boiled over into the Boxer Uprising. The "Boxers" were members of a secret society who practiced martial-arts rituals they believed made them invulnerable to bullets, and who blamed China's misery on foreigners and Christian missionaries. They rose to drive the "foreign devils" out of the land.

In 1900 the Boxers, tacitly encouraged by the aging Empress Dowager Cixi—the real power behind the throne for nearly half a century—besieged the foreign legations in Beijing. An eight-nation alliance, including Britain, France, Germany, Russia, Japan, and the United States, sent an army that crushed the Boxers, occupied the capital, and imposed yet another ruinous indemnity. It was the nadir of the humiliation: foreign soldiers marching in triumph through the heart of Beijing.

That child was Puyi, who became emperor in 1908 at the age of two. He would be the last. Discredited and bankrupt, the dynasty made a final, desperate push at reform—it had already abolished the ancient examination system in 1905, and now it promised a constitution. But it was far too late. Revolutionary feeling, especially among students and soldiers exposed to new ideas from Japan and the West, had become unstoppable. Revolutionaries inspired by Sun Yat-sen dreamed no longer of a better emperor, but of no emperor at all—of a Chinese republic.

In October 1911 an accidental bomb blast and an army mutiny in the city of Wuchang lit the fuse. Province after province declared its independence from the Qing. The helpless court turned to its most powerful general, Yuan Shikai, who negotiated the dynasty's surrender in exchange for the presidency of the new republic that was forming.

The Republic of China was proclaimed, with Sun Yat-sen as its first provisional president, soon yielding the office to Yuan Shikai. But the young republic was fragile, and China's ordeal was far from over—warlords, civil war, Japanese invasion, and a second revolution all lay ahead in the century to come. As for Puyi, the boy who had been the Son of Heaven: he would live on into a transformed world—briefly restored, later installed as a puppet ruler by the invading Japanese, and finally, remarkably, remade into an ordinary citizen and gardener in the People's Republic. The last emperor of the Middle Kingdom ended his days, in 1967, tending flowers.

Step back from the emperors and the rebellions, and the longer story swims into view. For more than three thousand years, in the valleys of the Yellow and Yangtze rivers, one civilization sustained an unbroken thread of writing, thought, and statecraft—while every other ancient civilization, Egypt and Sumer and Rome among them, rose to greatness and then vanished. That sheer endurance is itself China's first great gift to human history: living proof that a civilization can outlast any single dynasty, any conqueror, any catastrophe.

The material gifts are famous the world over. The Four Great Inventions—papermaking, printing, gunpowder, and the compass—each transformed the planet. Paper and printing carried knowledge to the masses and helped make possible the Reformation, the scientific revolution, and mass literacy itself. Gunpowder ended the age of castles and armored knights. The compass opened the oceans—and, with a certain historical irony, guided European ships to China's own shores. To these add silk, porcelain (which the world still calls "china"), the wheelbarrow, cast iron, paper money, and a long catalogue of lesser marvels.

The gifts of thought run just as deep. Confucian ethics—the emphasis on family, education, social harmony, and government by cultivated merit—shaped not only China but Korea, Japan, and Vietnam, and still guide the daily lives of well over a billion people. The imperial examination pioneered the radical proposition that the state should be run by those who earn their place through learning, an ancestor of every civil service and competitive exam in the world today. And the Mandate of Heaven bequeathed a political philosophy in which even the mightiest ruler is answerable to a higher standard, and a government that fails its people forfeits its very right to rule.

The imperial system ended in 1912, and the century that followed brought revolution, invasion, and transformation on a staggering scale—stories for another telling. But the civilization did not end when the emperors did. The script that Qin Shi Huang standardized is still written today. The classics that Confucius's students compiled are still quoted in the street and the boardroom. The Great Wall still climbs the mountains; the Forbidden City still stands at the heart of Beijing—no longer forbidden, walked now by millions.

From oracle bones cracked over a fire to the first empire, from the poetry of the Tang to the printing presses of the Song, from the treasure fleets to the last emperor tending his garden, the story of China is the longest continuous story humanity has to tell. Dynasty after dynasty claimed the Mandate of Heaven and, in time, lost it; the Middle Kingdom endured them all. That is perhaps the deepest lesson of these four thousand years: empires are mortal, but a civilization—carried in its writing and its memory—can be very nearly immortal.
