An Introduction to the Qin Empire (221–206 BCE)
The Qin empire(221–206 BCE) of China lasted only fifteen years, but the rise of the state of Qin began several decades earlier, and Qin’s defeat of all the other rival states brought a definative conclusion to the Warring States period (475–221 BCE). Ying Zheng, the future First Emperor, ascended the throne of Qin in the year 247 BCE at age thirteen, and only a few years later launched a series of military campaigns against the neighboring states of Han, Zhou, Wei, Chu, Yan and Qi, defeating the last in 221 BCE, ‘as a silkworm devours a mulberry leaf ’ according to the Han historian Sima Qian.
