Life

In brief

He took the throne after killing his elder and younger brothers in the Xuanwu Gate Incident, captured Illig Qaghan of the Turks, and was the second emperor of the Tang.

Road to the throne

He was the second son of Emperor Gaozu of Tang, and the Old Book of Tang records that he was named Shimin because a scholar said he had the look of one who would save the world (jishi) and bring peace to the people (anmin). In the uprising at the end of the Sui he tearfully dissuaded Gaozu from turning back to Taiyuan during the attack on Huoyi, and later captured Dou Jiande at Hulao, after which Wang Shichong also surrendered. In 626, saying that his elder brother, the crown prince Jiancheng, and his younger brother Yuanji, Prince of Qi, had been plotting to kill him, he killed them both at the Xuanwu Gate and was made crown prince. Within the same year Gaozu abdicated in his favor and he took the throne.

Reign and death

Soon after his accession Illig Qaghan of the Turks advanced as far as the Bian Bridge over the Wei River. Taizong rode out to the riverbank with six horsemen and spoke with Illig, and when the Tang army arrived behind him in full strength, Illig took fright and asked for peace, so Taizong made a covenant with him and sent him away. In 630 Li Jing defeated the Turks, and Illig Qaghan was captured and sent to Chang'an. In 645 he led an expedition against Goguryeo in person and defeated a relief army at Zhubi Mountain, but he could not take the fortress of Ansi and turned back. In 648, the basic annals of the Old Book of Tang say in a single phrase, he had the fangshi Narayanasvamin make a drug for prolonging life. He died in the Hanfeng Hall in 649, and the basic annals of the Old Book of Tang record only that he died. The New Book of Tang writes that he had been ill for about two months before he died, and gives his age at death as one year more than the Old Book of Tang does. In the biography of Hao Chujun in the same Old Book of Tang, Hao Chujun says that the late emperor took a long-life drug from a Brahmin monk to no effect, and that at the end even famous physicians could do nothing for him. In the annals of Emperor Xianzong, the chief minister Li Fan says that Taizong took a long-life drug from a foreign monk, fell suddenly ill and could not be saved, and these two passages are why this site lists his cause of death as disputed. The Zizhi Tongjian describes his end as worsening diarrhea and says the fangshi's drug was never completed, which conflicts with the account of Tianzhu (India) in the Old Book of Tang, where the drug is made and he takes it.
