About Li Chongjun

Li Chongjun, posthumous name 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.
