同治帝
When the Xianfeng Emperor died on 22 August 1861, his first son and successor, the Tongzhi Emperor, was still too young to rule. In the Xinyou Coup that followed, the Empresses Dowager Ci'an and Cixi collaborated with Yixin to overthrow and seize power from a group of eight regents appointed by the Xianfeng Emperor on his deathbed. The two empresses dowager thus became the regents for the Tongzhi Emperor, with Yixin assisting as Prince-Regent. On 6 May 1862, in order to secure Yixin's allegiance towards the Tongzhi Emperor, the two empresses dowager issued an imperial decree that added the character "cheng" to Empress Dowager Kangci's posthumous title. Empress Dowager Kangci was also given a place in the Imperial Ancestral Temple and included in ancestral worship rites.
