Xiaowen was the second son of
King Zhaoxiang of Qin and Queen Tang, and grandson of
Queen Dowager Xuan. He was the king of
Qin for less than one year, and died three days after his coronation. Various theories explaining his short reign have been proposed. The most accepted theory is that he was very old when he ascended to the throne, as his father had ruled for over 50 years. However, there is a
conspiracy theory that
Lü Buwei poisoned the king, or at least hastened his death, to put the next king,
King Zhuangxiang of Qin, onto the throne. ==Family==
