Xianfeng Emperor
Yizhu ascended the throne in 1850 after the death of the Daoguang Emperor and adopted the regnal title "Xianfeng"; he is thus historically known as the Xianfeng Emperor. In accordance with their father's secret edict, the newly enthroned Xianfeng Emperor granted Yixin the title "Prince Gong of the First Rank" (恭親王) in the same year. In 1851, the Xianfeng Emperor established an office for Prince Gong, gave him permission to enter the inner imperial court, assigned him to be in charge of patrol and defence matters, and ordered him to continue carrying the White Rainbow Sword given to him by their father.
