King Xiaowen of Qin
King Xiaowen of Qin (302–250 BC) was a Chinese king, who had a very brief reign. He is also known as Lord Anguo (安國君). His grandson was Emperor Qin Shi Huang. Biography. Xiaowen was a son of the King Zhaoxiang of Qin and Queen Tang and grandson of Queen Dowager Xuan. He was a king of the Qin for less than one year, and died three days after his coronation. This gave rise to many theories as to his short reign. The most accepted one is that he was very old when he ascended to the  throne (his father 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. This is supported in a way by the fact that Zhuangxiang reigned for only 3 years. Family. Queens: Sons:
