Empress Xiaojingcheng (19 June 1812 – 21 August 1855), of the Manchu Plain Yellow Banner Borjigit clan, was a posthumous name bestowed to a consort of Mianning, the Daoguang Emperor.
The future Empress Xiaojingcheng was born on the 11th day of the fifth lunar month in the 17th year of the reign of the Jiaqing Emperor, which translates to 19 June 1812 in the Gregorian calendar.
According to imperial customs, Imperial Noble Consort Dowager Kangci had no right to claim the position of empress dowager because she was neither the birth mother of the Xianfeng Emperor, nor did she hold the rank of Empress while the Daoguang Emperor was still living.
Fearing that she had little time left, she conspired with her son, Yixin, to earn her the title of empress dowager before she died.
Yixin then issued an imperial edict to honor his mother without full consent of the Xianfeng Emperor.
The Xianfeng Emperor appointed two princes, one of whom was Yixin, to take charge of the funeral arrangements, and announced that he would spend the mourning period in the Hall of Mental Cultivation.
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.
