Qin Dynasty

The Qin Dynasty, though it lasted only about fifteen years, was one of the most consequential in Chinese history, for it created the first unified imperial Chinese state.

It arose from the state of Qin, one of the contending powers of the Warring States period, which under a series of able and ruthless rulers and ministers had built a formidable military and administrative machine grounded in the harsh philosophy of Legalism. In 221 BCE the Qin king completed the conquest of the rival states and unified China, proclaiming himself Qin Shi Huang, the 'First Emperor.' His reign, guided by the chancellor Li Si, imposed sweeping standardisation across the new empire: a single system of writing, uniform weights, measures, and currency, standardised axle widths, and a centralised bureaucracy of commanderies and counties administered by appointed officials rather than hereditary nobles. These measures laid enduring foundations for Chinese statecraft. The Qin also undertook massive construction projects using forced labour, including early connecting walls that were precursors to the Great Wall, an extensive road network, and the emperor's vast mausoleum guarded by the famous Terracotta Army. Qin rule was, however, severe and repressive, marked by heavy taxation, brutal punishments, conscription, and the suppression of dissent, including the notorious burning of books and persecution of scholars. After the First Emperor died in 210 BCE, the dynasty rapidly unravelled amid succession intrigues, popular uprisings, and rebellion against its oppressive demands. It collapsed in 206 BCE, and after a period of civil war the succeeding Han Dynasty inherited and softened the Qin's centralised framework, which would shape imperial China for two millennia.
