Qin unites China (247–221 BC)

King Zhuangxiang of Qin ruled for only three years. He was succeeded by his son Zheng, who unlike the two elderly kings that preceded him was only 13 years old at his coronation. As an adult Zheng would turn out to be a brilliant commander who, in the span of just nine years, unified China.
