道光帝
When the Daoguang Emperor died on 15 February 1850, his fourth son, Yizhu, succeeded him and was enthroned as the Xianfeng Emperor. The Xianfeng Emperor's primary consort had died a month before the emperor's coronation and was posthumously honoured as "Empress Xiaodexian". The process of selecting a new primary consort to be the Xianfeng Emperor's empress consort, however, was delayed due to the mourning period for the Daoguang Emperor.
