Zhu Youzhen
In 912, Emperor Taizu was assassinated at the capital Luoyang by his son Zhu Yougui the Prince of Ying, who then took the throne himself after blaming the assassination on his adoptive brother Zhu Youwen the Prince of Bo and putting Zhu Youwen to death. However, many officials suspected Zhu Yougui of being responsible, and shortly after Zhu Yougui's ascension, Zhao Yan entered into a plot with Emperor Taizu's nephew Yuan Xiangxian (a fellow commander in the imperial guards) and the major general Yang Shihou, as well as another son of Emperor Taizu's, Zhu Youzhen the Prince of Jun, to overthrow Zhu Yougui and support Zhu Youzhen as emperor. In spring 913, Yuan sent his soldiers into the palace and had Zhu Yougui surrounded, and Zhu Yougui committed suicide. Yuan and Zhao sent the imperial seal to the eastern capital Daliang, where Zhu Youzhen was at the time. Zhu Youzhen accepted and took the throne at Daliang, making it the capital.
