Qin dynasty

• 1. Introduction

  ›

  The Qin dynasty ruled China for only 14 years, from 221 to 206 BC, yet the political system it built outlasted it by more than two thousand years. A man named Ying Zheng, who had come to the Qin throne at age nine, spent the following decades dismantling every rival kingdom on the continent. By the time he was done, he held a title that had never existed before: Shi Huangdi, meaning the First Emperor. What made a state that had begun as a minor horse-breeding settlement become the force that unified China? How did it build cities, armies, and bureaucracies that the far longer-lived Han dynasty would simply inherit and continue? And why did it collapse so completely within four years of its founder's death? The answers stretch back to the 9th century BC, wind through a brutal age of warring kingdoms, and end with a burning capital and a new emperor declaring himself ruler of the world.

• 2. From Pasture to Power

  ›

  In 897 BC, during the Gonghe Regency, the territory that would become Qin was allocated as a dependency dedicated to raising horses for the Zhou court. Its ruler, Feizi, was said to descend from the legendary political advisor Gao Yao; he was granted control over the settlement of Qin, in what is now Qingshui County, Gansu. For centuries the state remained a peripheral actor, useful for military service but never a dominant force.

  In 770 BC, Duke Xiang, a descendant of Feizi, performed a service that changed everything. He escorted the Zhou court under King Ping during an emergency evacuation from Fenghao to Chengzhou, when the Western Rong peoples threatened the old capital. As a reward, Duke Xiang was sent to lead an expedition to recapture the territory the Western Rong had taken. He succeeded, formally establishing Qin as a major vassal state and incorporating Fenghao along with much of the land that had once been directly controlled by the Zhou. This single campaign pushed Qin eastward and gave it a foothold in the heart of China.

  The state began military expeditions into central China in 672 BC. For nearly two more centuries, neighbouring tribes to the west checked its expansion; by the 4th century BC, those tribes had either been subdued or conquered, opening the way for what would follow.

• 3. The Reformer Who Made It Possible

  ›

  Between 359 BC and his execution in 338 BC, the statesman Shang Yang reshaped Qin from the ground up. He introduced military reforms, rationalised agriculture, and helped construct the Qin capital at Xianyang, on the Wei River near the former Zhou capital of Fenghao. Shang Yang was executed by King Huiwen due to a personal grudge harboured from the king's youth, yet his reforms survived him and powered the state's rise.

  His agricultural policy aimed to maximise the area of land under cultivation. The state cleared most of the forest in the Yellow River valley and converted it into farmland, divided into household-sized allotments. Inhabitants were forcibly relocated to work them. Shang Yang also emphasised using hoes to weed the soil, which improved its ability to retain moisture. Later projects extended this logic: a canal off the Wei River, said to have been engineered by Zheng Guo in 246 BC, expanded Qin's irrigated territory further.

  Qin's geography reinforced everything Shang Yang built. The core territories sat in the Guanzhong, a region of fertile farmland protected by mountains on all sides. It was the only capital in China during this period that required no walls. The surrounding flatlands, known as the Guandong, were exposed by contrast, and a Han-era adage captured the difference precisely: 'Guanzhong produces generals, while Guandong produces ministers.'

  Shang Yang's registration system, introduced to Qin during the 4th century BC and thought to have been established in 375 BC, may have been his most lasting administrative invention. Initially it collated the names of individuals; it later tracked entire households. Under its rules, households were grouped into units of five, with the heads of each household made mutually responsible for reporting wrongdoing committed by any member. Under King Ying Zheng, the system was extended in 231 BC to record the ages of adult men specifically, providing a tool for military conscription and taxation of unprecedented precision.

• 4. Conquest and the New Title

  ›

  The military tradition Qin was displacing had treated war as a nobleman's affair. A story from the preceding Spring and Autumn period captures the old ethos: Duke Xiang of Song, waging war against Chu, declined to attack Chu forces while they were crossing a river. After allowing them to cross and form their ranks, he was decisively defeated. When his advisors rebuked him, he replied: 'The sage does not crush the feeble, nor give the order for attack until the enemy have formed their ranks.' Qin regarded this as folly.

  A nobleman from Wei described Qin as 'avaricious, perverse, eager for profit, and without sincerity. It knows nothing about etiquette, proper relationships, and virtuous conduct, and if there be an opportunity for material gain, it will disregard its relatives as if they were animals.' That ruthlessness, combined with long-lived rulers, a willingness to employ talented men from other states, and an absence of internal opposition, built a political base none of the other six major states could match.

  Beginning in 230 BC, Ying Zheng moved against each rival in turn. Qin struck Han to the east first, taking its capital Xinzheng in 230 BC. Zhao surrendered in 228 BC, and Yan fell in 226. Moving east and south, Qin took the Wei capital of Daliang, modern Kaifeng, in 225 BC, and forced Chu to surrender in 223. The Zhou dynasty's remnants were deposed at Luoyang; then Qi fell, with its capital Linzi taken in 221 BC.

  With all six states subdued, Ying Zheng combined the titles of the earlier Three Sovereigns and Five Emperors into a new compound name: Shi Huangdi, the First Emperor. He confiscated all weapons not held by Qin forces and had them melted down; the resulting metal was cast into twelve large ornamental statues at Xianyang. His prime minister, Lü Buwei, then abdicated, leaving Qin Shi Huang as sole ruler of a unified empire.

• 5. Building the Infrastructure of Empire

  ›

  The empire Qin Shi Huang inherited needed to be held together as much as it had needed to be won. The government divided the territory into 36 commanderies, subdivided into more than a thousand districts, each administered by appointed officials rather than members of the royal family. A supervisory body called the Censorate monitored these administrators at every level. All aspects of life were standardised: measurements, language, and even the length of chariot axles so that roads built to one standard could be used by vehicles from any region.

  Qin Shi Huang also instituted a permanent ranking system for soldiers consisting of twenty grades, determined by enemies killed in battle or by commanding victorious units. Ranks were not hereditary under most circumstances, though a soldier who died heroically in battle could pass his rank to his family. Each rank came with specific allotments of dwellings, slaves, and land, and could also be used to reduce judicial penalties.

  The era's most visible projects were built on this foundation. The northern border walls built by former feudal lords were connected and reinforced, forming the base of what would eventually become the Great Wall of China; roughly a hundred thousand men secured that frontier while the majority of the army, around five hundred thousand men, was deployed south against the Baiyue peoples in 214 BC. The Baiyue campaign began badly: the Qin army was unfamiliar with jungle terrain and lost over a hundred thousand men to guerrilla tactics. But a canal built during that first campaign allowed the army to supply its second push south; Qin forces ultimately took coastal lands around Guangzhou and the provinces of Fuzhou and Guilin, with some accounts suggesting they may have reached as far as Hanoi. Over a hundred thousand prisoners and exiles were then moved to colonise the newly conquered territory.

  The Terracotta Army, built to guard Qin Shi Huang after his death, remained underground and undiscovered until 1974. Its very concealment was intentional: the city-sized mausoleum complex and its life-sized ceramic soldiers were not meant to be seen.

• 6. Death, Conspiracy, and Collapse

  ›

  Three assassination attempts had been made against Qin Shi Huang during his lifetime, one by Jing Ke in 227 BC and two more around 218 BC. By the time of his final tour of the eastern frontiers, the emperor had become paranoid and fixated on immortality. He died in 210 BC while attempting to obtain an elixir of immortality from Taoist practitioners who claimed the elixir was held on an island guarded by a sea monster.

  The chief eunuch Zhao Gao and prime minister Li Si concealed the emperor's death on the journey home until they could alter his will. His eldest son Fusu had been intended to inherit the throne; instead, Li and Zhao forged an order commanding Fusu to commit suicide and installed a younger son, Huhai, in his place under the name Qin Er Shi. The two men expected to govern through him.

  Qin Er Shi proved ruinous. He executed ministers and imperial princes, continued vast construction projects including lacquering the city walls, enlarged the army, raised taxes, and had messengers arrested for delivering bad news. Men across China revolted, seizing territories and declaring themselves kings. Li Si and Zhao Gao then turned on each other; Zhao persuaded Qin Er Shi to put Li on trial, resulting in Li's execution. When the military situation deteriorated, the emperor blamed Zhao, who then staged a deception to make Qin Er Shi believe hostile forces had entered the capital. The emperor was cornered by Zhao's son-in-law and forced to commit suicide.

  Fusu's son Ziying took the throne, immediately executed Zhao Gao, and attempted to survive by declaring himself merely one king among equals. It was too late. Popular revolt had broken out in 209 BC. When Liu Bang's forces arrived at Xianyang in 207 BC, Ziying surrendered; he was initially spared but then executed by the Chu leader Xiang Yu. In 206 BC, Xianyang was destroyed. On the 28th of February 202 BC, Liu Bang declared himself emperor of the Han dynasty, the successor state that would govern China for the next four centuries largely through structures the Qin had built.

• 7. What the Qin Left Behind

  ›

  Han dynasty scholars of the 2nd and 1st centuries BC worked to portray the Qin as a monolithic legalist tyranny, a cautionary example invoked in debates about their own imperial policy. The purges of 213 and 212 BC, known collectively as the burning of books and burying of scholars, became central to that portrait. The earliest account of these events appears in the Shiji, written around 91 BC, and its accuracy is contested by some modern scholars.

  What is harder to dispute is the structural continuity. The Han inherited the household registration system, the bureaucratic hierarchy, the standardised currency, and the administrative logic the Qin had imposed. Medieval and modern historians have often grouped the two dynasties together, treating the founding of the Han primarily as a change in ruling family rather than a change in system.

  The writing reform that Qin Shi Huang introduced carries consequences still visible today. Small seal script was promulgated across the empire on public stone monuments, with the Book of Han recording that Li Si distributed detailed instructions to scribes in 221 BC, though those instructions are lost. Regional divergences in character forms were reduced considerably, even if variant characters continued to appear in practice. The Qin established an imperial academy and library with appointed scholars to interpret and oversee texts, a model the Tang dynasty later extended by requiring court approval for all stele inscriptions.

  The name 'China' itself may trace directly to Qin. The term appears in Sanskrit as both Cina and Sina, then entered Greek as Thinai or Sinai, and from there spread through European vernaculars as China in English and Chine in French. Some scholars question this etymology, noting that Sina appears in Sanskrit before the Qin dynasty's founding; alternative candidates include the Zhou-era state of Jin and Jing, another name for the state of Chu. The question remains open, which is itself a measure of how thoroughly Qin embedded itself in the story of what China would become.
