Emperor Ai of Tang
In 904, Zhu forced Emperor Zhaozong to move the capital from Chang'an to Luoyang, which was even more firmly under his control. Later that year, fearing that the adult Emperor Zhaozong would try to rise against him while he was away on campaigns against other warlords, he had Emperor Zhaozong assassinated. Bypassing Li Yu and the other older princes, he had an edict issued in Emperor Zhaozong's name creating Li Zuo crown prince and changing his name to Li Chu. Shortly after, Li Chu took the throne (as Emperor Ai). Empress He, who survived the assassination, was honored empress dowager.
Trần Thị Dung
Trần Thị Dung's complicated biography was a fine example for the complex period of the Late Lý and Early Trần Dynasty in History of Vietnam. Reflecting her role in the Lý and Trần Dynasty, the historian Ngô Sĩ Liên wrote that Trần Thị Dung did had an active role in reinforcing the newly found reign of the Trần Dynasty, especially with the matter of Trần Thái Tông-Trần Liễu clash and during the war of resistance of the Trần Dynasty against the Mongol invasion. However, being the last empress and the last empress mother of the Lý Dynasty, she contributed nothing to the ruling of the Lý Dynasty and even married Trần Thủ Độ, who forced her first husband Lý Huệ Tông commit suicide, a decision that was criticized in several historical books.
