Shang Yang's Reforms (356 BC): Legalism Transforms the Qin State

Shang Yang’s reforms were a series of radical changes to the law, land system and army of the Chinese state of Qin, introduced from 356 BC under Duke Xiao. The minister Shang Yang replaced aristocratic privilege with a system of strict laws, collective responsibility and rewards for farming and fighting. His reforms made Qin the strongest state of the Warring States period and laid the foundations for the first unified Chinese empire.

Background

In the mid-4th century BC Qin lay on the western edge of the Chinese world, in the Wei River valley of modern Shaanxi. Other states regarded it as backward and semi-barbarian. It had recently lost land west of the Yellow River to its powerful eastern neighbour Wei, one of the states formed by the partition of Jin.

When Duke Xiao came to power in 361 BC, he issued an appeal for talented men to help restore Qin’s strength. Among those who answered was Gongsun Yang, a member of the ruling family of the small state of Wey. He had served a minister in Wei but found no advancement there. He later became known as Shang Yang, from the territory of Shang that Qin granted him.

The first reforms, 356 BC

Shang Yang won the duke’s support in debate against conservative ministers, named by Sima Qian as Gan Long and Du Zhi, who argued that ancient customs should not be changed. Shang Yang replied that there was no single way to govern every age, that the great rulers of the past had each made their own laws, and that a state did not need to copy antiquity if change would benefit it. Duke Xiao sided with him and appointed him to high office.

His first set of laws, issued in 356 BC, reorganised society around two activities, farming and war. Their main features were:

• Collective responsibility. Households were organised into groups of five and ten. Members were obliged to report crimes; those who failed to do so were punished as if guilty, while informers were rewarded.
• Ranks for military merit. Noble status now depended on success in battle, measured by enemy heads taken, rather than birth. Members of the ruling clan without military merit lost their privileged status.
• Farming over commerce. Families who produced large harvests of grain or cloth were exempted from labour service, while those who turned to trade or were idle could be enslaved.
• Splitting households. Households with two or more adult men who did not divide were taxed at double rates, increasing the number of taxpaying units.

According to Sima Qian, Shang Yang worried that people would not trust the new laws. He set up a pole at the south gate of the market and offered ten pieces of gold to anyone who would carry it to the north gate. No one believed him, so he raised the reward to fifty. When a man moved the pole, he was paid in full.

The second reforms, 350 BC

In 350 BC Qin moved its capital to Xianyang, where a new palace complex was built. A second round of reforms followed. Small settlements were merged into about thirty counties (xian), each run by officials appointed by and answerable to the ruler, not by local nobles. Fathers and adult sons, and adult brothers, were forbidden to live together in one household, further breaking up large family groups into small farming units that the state could register, tax and conscript directly.

The old field boundaries were removed and land was redistributed, encouraging farmers to open new land; historians debate exactly how the new system worked. Weights and measures were standardised. A surviving bronze vessel, the Shang Yang square sheng now in the Shanghai Museum, carries an inscription dating it to 344 BC and shows this policy in action.

Enforcement and enemies

The laws were applied harshly and, at least in principle, to everyone. When the crown prince broke a law, Shang Yang could not punish the heir himself, so he punished the prince’s tutors instead: Gongsun Jia was tattooed on the face, and Gongzi Qian, punished at the time, later had his nose cut off for a further offence. This made him powerful enemies.

Shang Yang also led Qin’s armies. In 340 BC, after Wei had been weakened at the Battle of Maling, he invaded Wei and captured its commander, Gongzi Ang, by inviting him to a peace meeting. Qin regained land in the west, and Shang Yang was rewarded with fifteen settlements in the region of Shang, taking the title Lord of Shang.

Fall and death

Duke Xiao died in 338 BC and was succeeded by the former crown prince, later known as King Huiwen. Shang Yang’s enemies accused him of plotting rebellion. He fled, but according to Sima Qian an innkeeper refused to give him a room because, under Shang Yang’s own laws, guests without travel documents could not be lodged.

He tried to raise forces in his fief but was defeated and killed. His body was torn apart by chariots in public, and his whole family was executed. Yet the new ruler kept his laws in force.

Legacy

Shang Yang is regarded as one of the founders of the school of thought later called Legalism, which held that order comes from clear laws, rewards and punishments rather than moral example. A work called the Book of Lord Shang was compiled under his name, although much of it was probably written by later followers. The philosopher Han Fei drew on his ideas in the 3rd century BC, as discussed in Han Feizi and Legalism.

The system he created allowed Qin to mobilise its population for war more effectively than any rival. Over the next century Qin expanded steadily and achieved the unification of China in 221 BC. Later Confucian writers condemned Shang Yang as cruel, and his reputation has swung between admiration for his efficiency and criticism of his severity ever since.

Archaeology has shown how deeply this model took root. In 1975 bamboo slips found in the tomb of a Qin official at Shuihudi, Hubei, who died around 217 BC, preserved detailed Qin statutes on farming, granaries, labour service, punishments and the duties of officials. They reveal a state that recorded its population, harvests and livestock with great care, very much in the spirit of Shang Yang’s reforms.

The Han-dynasty writer Jia Yi, in his essay “The Faults of Qin”, argued that Qin’s harsh methods won an empire but could not keep it, since the dynasty collapsed in 206 BC. Yet the Han dynasty kept much of the Qin administrative system. In the 20th century Shang Yang was reassessed again, and during the anti-Confucius campaign of the early 1970s in China, Legalist reformers were officially praised as progressive.

Why it matters

Shang Yang showed how a weak state could be rebuilt into a war machine through law and central control. His model of bureaucratic government, based on counties and officials rather than hereditary lords, shaped Chinese administration for two thousand years.
