Li Chongjun (李重俊) (died 7 August 707), formally Crown Prince Jiemin (節愍太子), was a crown prince of the Chinese Tang Dynasty, during the second reign of his father Emperor Zhongzong. He was made crown prince because the only son of his father's wife Empress Wei, Li Chongrun, had been killed before his father's return to the throne, but on account of his mother's low birth, he was often humiliated by Empress Wei's daughter Li Guo'er the Princess Anle and her husband Wu Chongxun (武崇訓). In 707, in anger, he started a coup and killed Wu Chongxun and his father Wu Sansi the Prince of Dejing, but his subsequent attempt to arrest Empress Wei, Li Guo'er, and Consort Shangguan Wan'er was thwarted, and he was killed in flight. Background It is not known when Li Chongjun was born, but it was recorded that he was the third son of Emperor Zhongzong (Li Xian), although his younger brother Emperor Shang was born in either 695 or 698, and so he must be born sometime there before. It is not known who his mother was other than that she was not Emperor Zhongzong's wife Empress Wei. It is further unknown whether he was born before or during Emperor Zhongzong's brief first reign in 684, or during his exile from 684 to 698. However, upon the recall of Li Xian, then carrying the title of Prince of Lulin during the reign of Li Chongjun's grandmother Wu Zetian, to the capital Luoyang, Wu Zetian created Li Chongjun the Prince of Yixing. In 705, Li Xian was restored to the throne after Wu Zetian was overthrown in a coup. He created Li Chongjun the Prince of Wei and made him the prefect of Luo Prefecture (洛州, i.e., Luoyang). He was also made a general and the commandant at Yang Prefecture (揚州, roughly modern Yangzhou, Jiangsu), although he remained at Luoyang and did not report to Yang Prefecture. As crown prince In 706, Li Chongjun was created crown prince. It was said that he was intelligent and decisive, but because he lacked good teachers, he did not act properly. Emperor Zhongzong made his brothers-in-law Yang Shenjiao (楊慎交) the husband of Princess Changning and Wu Chongxun the husband of Li Guo'er the Princess Anle his advisors. It was said that all Yang and Wu did were to play sports with Li Chongjun and were not carrying out actions
