Shang Yang

Shang Yang (c. 390–338 BCE), also known as Wei Yang after the ruling family of the small state of Wei, was a statesman and reformer of the State of Qin during the Warring States period of ancient China. He is one of the best-known representatives of Legalism, the current that defended the rule of law and the authority of the ruler over tradition and aristocratic privilege. His importance lies in the fact that his reforms laid the administrative, political and economic foundations on which Qin, then a peripheral state, would eventually unify China.

He was born the son of a concubine in the ruling family of Wei, belonging to the Gongsun lineage. He studied law and held a minor post in Wei, but never rose to a prominent position there. Around 359 BCE he entered the service of Qin, drawn by Duke Xiao, who was seeking talent from abroad. For roughly twenty years he served as the ruler's chief minister and launched two series of reforms. Many of his measures had precedents in other states, such as those attributed to Wu Qi in Chu, but Yang applied them in a more methodical and radical way, concentrating power in the hands of the ruler.

His ideas revolved around several areas. In law, he extended collective responsibility to criminal matters: families had to report crimes, and anyone who concealed one faced the same punishment as the offender. In administration, he weakened the fiefs, divided the territory into districts run by officials, and standardized weights and measures. In taxation and society, he imposed a double tax on households with several adult men, aiming to break up large clans and bring individuals under direct state control. Economically, he favoured farming over commerce and rewarded those who exceeded harvest quotas. Sources also record harsher measures, such as enslaving farmers who failed their quotas and attracting peasants from other states to offset a labour shortage.

His military successes were considerable. In 341 BCE he led the army that defeated Wei, earning a fief of fifteen cities and the title Lord of Shang. However, his severe laws and the loss of privileges by the old aristocracy made him many enemies. After the death of Duke Xiao, the new ruler had him executed, together with his family. According to tradition, he was torn apart by chariots, although several versions of his death have survived. Even so, the new king kept many of his reforms.

His influence proved lasting. Texts linked to his school, gathered in The Book of Lord Shang, circulated widely, and Han Feizi, the great Legalist thinker, took them as a point of reference. Sima Qian gave him a place in his Records of the Grand Historian, and the Han dynasty adopted much of his conception of equality before the law. Today he is regarded as one of the architects of the centralized Chinese state.
