Li Si

As Chancellor of Qin, Li Si oversaw the standardization of Chinese script, replacing regional variations with a uniform writing system. This reform facilitated communication and administration across the newly unified empire.

Li Si implemented uniform standards for weights, measures, and axle lengths across the Qin Empire. This reform facilitated trade, taxation, and transportation, contributing to economic integration and central control.

Li Si oversaw the construction and linking of existing fortifications into a unified Great Wall to protect the Qin Empire from northern nomadic incursions. The project required massive conscript labor and resulted in many deaths.

Li Si advised Emperor Qin Shi Huang to burn historical records, philosophical texts, and poetry that criticized Legalism, and to bury alive 460 Confucian scholars who opposed the regime. This act aimed to suppress dissent and enforce ideological uniformity.

After the death of Qin Shi Huang, Li Si was involved in a power struggle with the eunuch Zhao Gao. Zhao Gao falsely accused Li Si of treason, and he was executed by the Five Pains method (dismemberment). His family was also exterminated.
