Qin Great Wall Construction
Several of the Warring States, including Qin, Zhao, and Yan, had already built defensive walls along their northern frontiers against nomadic raiders before unification. In 214 BCE, following General Meng Tian's campaigns pushing the Xiongnu confederation north of the Ordos Loop, Qin Shi Huang ordered these separate walls linked and extended into a continuous fortification stretching roughly 5,000 kilometres. The project conscripted labour on a massive scale — traditional accounts, likely exaggerated but reflecting genuine severity, claim hundreds of thousands of workers and soldiers died from exhaustion, exposure, and forced-labour conditions, their bodies reportedly incorporated into the wall's foundations in popular legend. The Qin wall used rammed earth rather than the brick and stone of the later, better-preserved Ming-era wall that tourists visit today; almost none of the Qin structure survives above ground. The wall's purpose was less an impermeable barrier than an early-warning and troop-mobility system: garrisoned watchtowers signalled raids by fire and smoke, while the wall itself channelled nomadic cavalry into defensible corridors and gave Qin forces rapid lateral movement.
