Wang Shichong - Death

Death

Li Shimin took Wang Shichong and Dou Jiande back to the Tang capital Chang'an to present them to his father Emperor Gaozu. When Emperor Gaozu met Wang and rebuked him, Wang stated, "I should be beheaded, but the Prince of Qin had agreed to spare me." In fall 621, Emperor Gaozu spared him but demoted him to commoner rank, exiling him and his clan to modern Sichuan, while executing Dou.

Meanwhile, Wang and his family members were awaiting exile, and were detained at the barracks of the capital prefecture, Yong Prefecture (雍州). Dugu Xiude, the son of Dugu Ji, took the opportunity to enter the barracks, claiming that Emperor Gaozu wished to see Wang Shichong. Wang Shichong and his brother Wang Shiyun came out to greet Dugu, and Dugu executed them to avenge his father. Emperor Gaozu only punished Dugu by removing him from his post as the prefect of Ding Prefecture (定州, roughly modern Baoding, Hebei). The other members of the Wang clan were exiled, but on their way plotted rebellion, and were all executed.

Of all of the contenders to rule the empire during Sui's disintegration, Wang was one of the most reviled by traditional historians. The Later Jin Dynasty historian Liu Xu, the lead editor of the Book of Tang, commented:

Wang Shichong was a wicked man who happened to encounter an incompetent ruler. He flattered the emperor and did what others could not have done in exchange for wealth and honor. To his subordinates, he used wrongful rhetoric to hide his own faults and suppress dissent. He finally usurped the throne, carried out improper acts, and killed many cruelly. He used false expressions of empathy to control his officials. His subordinates were almost all rebels or desperate men. He finally surrendered to the Prince of Qin and was quite fortunate that he was not publicly beheaded.
