Daoguang Emperor
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.
