According to the Records of the Grand Historian, after Qin Shi Huang, the first emperor of China, unified China in 221 BCE, his chancellor Li Si suggested suppressing the freedom of speech, unifying all thoughts and political opinions. This was justified by accusations that the intelligentsia sang false praise and raised dissent through libel.
Beginning in 213 BCE, all classic works of the Hundred Schools of Thought — except those from Li Si's own school of philosophy known as legalism — were subject to book burning.
Qin Shi Huang burned the other histories out of fear that they undermined his legitimacy, and wrote his own history books. Afterwards, Li Si took his place in this area.
Li Si proposed that all histories in the imperial archives except those written by the Qin historians be burned; that the Classic of Poetry, the Classic of History, and works by scholars of different schools be handed in to the local authorities for burning; that anyone discussing these two particular books be executed; that those using ancient examples to satirize contemporary politics be put to death, along with their families; that authorities who failed to report cases that came to their attention were equally guilty; and that those who had not burned the listed books within 30 days of the decree were to be banished to the north as convicts working on building the Great Wall. The only books to be spared in the destruction were books on medicine, agriculture and divination.
The quick fall of the Qin Dynasty was attributed to this proscription. Confucianism was revived in the Han Dynasty that followed, and became the official ideology of the Chinese imperial state. However, many of the other schools of thought disappeared.
The events eventually became a Chinese Four-character idiom to describe general policies against educated people. Zhang Jie (章碣), a poet of the Tang Dynasty, wrote a poem that refers to this policy:
The poet captures the irony that after all the troubles the Emperor had gone through to oppress scholars and the educated, it turned out that the two people who would end the Qin Dynasty, Liu Bang and Xiang Yu, were not intellectuals of any kind.
