東太后
Zaitian was named heir and successor to his late uncle, the Xianfeng Emperor, rather than his cousin and predecessor, the Tongzhi Emperor, so as to maintain the father-son succession law. He ascended to the throne at the age of four and adopted "Guangxu" as his regnal name, therefore he is known as the "Guangxu Emperor". He was adopted by Empress Dowager Ci'an and Cixi. For her part, she remained as regent under the title "Holy Mother, Empress Dowager" (聖母皇太后) while her co-regent Empress Dowager Ci'an was called "Mother Empress, Empress Dowager" (母后皇太后).
