Who they are

With the backing of Duke Xiao of Qin, Shang Yang carried out two rounds of reform, turning a backward Qin into a war machine: abolishing the well-field system and opening the fields to recognize private land ownership; establishing commanderies and counties and household registers, bringing every person under state management; setting up twenty ranks of military merit, one rank awarded for each enemy head — nobles without merit were struck from the rolls just the same. Twenty years of reform left Qin so ordered that "nothing lost on the road was picked up, and there were no bandits in the hills," and made it the most feared enemy of the six states. After Duke Xiao died, the old nobles stripped of their privileges struck back; fleeing, Shang Yang sought lodging at an inn, and the keeper said: by Lord Shang’s law, taking in a guest without papers brings joint punishment — turned away by his own law, in what the histories call "undone by his own statute," he was finally torn apart by chariots.

Key stories

Moving the pole to build trust

With the new law drafted but not yet promulgated, Shang Yang feared the people would not trust it. He set a thirty-foot pole at the capital’s south gate and announced ten pieces of gold for anyone who moved it to the north gate. No one dared — where in the world was there such easy money? The reward was raised to fifty, and one man tried it and was paid on the spot. The new law was promulgated the next day. What he bought was not the moving of a pole but those five words, "the government keeps its word" — he knew the whole force of the new law hung on it.

The crown prince breaks the law

A year into the new law, the crown prince broke it. Shang Yang said, "The law fails when it is broken from above." The prince, as heir, could not be punished, so his tutor Prince Qian was punished and his teacher Gongsun Jia was branded. After that no one dared speak against the new law. But that debt did not vanish — when the prince took the throne as King Huiwen, Prince Qian accused Shang Yang of treason, and the punishment of dismemberment by chariots followed at once. The reformer died for his law, and his law went on running in Qin unchanged.
