Less than a month later, believing that Empress Dowager Wei would act against them, Emperor Zhongzong's sister Princess Taiping and nephew the Prince of Linzi rose in rebellion, killing Empress Dowager Wei and Li Guo'er. Li Longji's father the Prince of Xiang, himself a former emperor, became regent instead, and the popular sentiment at the time called for Li Dan to return to the throne. When eunuchs and attending to the young Emperor Shang requested that one of the coup leaders who became a chancellor immediately after the coup, Liu Youqiu, draft an edict to let Emperor Shang to honor his mother as empress dowager, Liu refused and hinted that Li Dan should be emperor, and while Li Longji publicly told Liu not to speak any further, Li Longji, his brother Li Chengqi the Prince of Song, and Princess Taiping were trying to persuade Li Dan to take the throne. Several days later, Li Dan agreed, and he took the throne, displacing Emperor Shang, who was still sitting on the throne during the ceremony and whom Princess Taiping grabbed by the collar to pull down from the throne. He was again given the title of Prince of Wen.
