Huo Guang
Shi was less than a year old when something highly unusual happened to his father. Shi's great-granduncle, Emperor Zhao, had died that year and the regent, Huo Guang, having been dissatisfied with his initial selection of Prince He of Changyi, deposed Prince He and offered the throne to the commoner Bingyi instead. Bingyi accepted and took the throne as Emperor Xuan. Shi's mother Xu Pingjun was created empress.
