The Qin dynasty: unity, power, and the first Chinese emperor

Few dynasties in Chinese history were so short-lived and yet exercised such great and lasting influence as the Qin dynasty. In just fourteen years—from 221 to 207 BC—the Qin state united all Chinese territories under one central authority for the first time, laid the foundation for the Chinese bureaucratic state, and created a political and cultural framework that still characterizes China today. The Qin period was also a turning point for Traditional Chinese Medicine.

The first emperor of China

The architect of the Qin dynasty was Ying Zheng, king of the state of Qin. After a series of military campaigns, he succeeded in conquering the six rival states—Han, Wei, Chu, Yan, Zhao, and Qi—and bringing them under his rule. For the first time in Chinese history, a truly united empire became a reality. Ying Zheng no longer considered the existing royal title sufficient for the scale of his power and called himself Qin Shi Huangdi—the First Emperor of Qin. The title "Huangdi" deliberately referred to the mythical Yellow Emperor Huang Di and expressed the ambition to establish a new golden age.

Standardization as a political instrument

One of Qin Shi Huangdi's most far-reaching measures was the systematic standardization of weights, measures, script, and currency throughout the empire. This may sound like an administrative measure, but it had far-reaching cultural consequences. By standardizing the script, communication across the borders of the former states became possible—and with it the spread of knowledge, including medical knowledge.

For TCM, this represented an important moment: medical texts and practices that had previously been regional could now be disseminated and shared more widely. The standardization of script was a precondition for the later systematization of Chinese medicine in the Han period that followed.

The Great Wall and the price of unity

Qin Shi Huangdi had the existing defensive walls of the individual states connected and expanded into what would later become the Great Wall. This gigantic construction project required an enormous labor force and cost countless lives. The regime of the First Emperor was authoritarian and ruthless: critics were punished, and books that displeased the regime were burned—including philosophical and medical texts.

This burning of books had direct consequences for the transmission of early medical knowledge. Many texts were lost. What remained were the works that had been preserved in secret or had stayed beyond the reach of imperial censorship. The destruction of knowledge in the Qin period makes it all the more remarkable that the Chinese medical tradition nevertheless maintained such a rich and continuous line of transmission.

A short but decisive period

The Qin dynasty lasted only fourteen years—after the death of Qin Shi Huangdi in 210 BC, chaos broke out and the empire fell apart. Yet the structures he had created—the centralized empire, the bureaucratic state, and the standardized script—outlived the dynasty itself and formed the basis on which the Han dynasty would build. And it was in the Han period that Traditional Chinese Medicine would take on its classical form.

The Qin dynasty is therefore a paradoxical chapter in the history of TCM: a period of destruction and unification, of loss and of the conditions for a new flourishing.
