Dou Wu
When Emperor Huan died in 168 without a son to succeed him, his empress, Empress Dou, became empress dowager, and she examined the genealogy of the imperial clan to choose a candidate to be the next emperor. For reasons unknown, her assistant Liu Shu () recommended Liu Hong, the Marquis of Jiedu Village. After consulting with her father Dou Wu and the Confucian scholar-official Chen Fan, Empress Dowager Dou installed a 12-year-old Liu Hong on the throne, and continued ruling on his behalf as regent. The newly enthroned Emperor Ling bestowed posthumous titles on his grandfather, father and grandmother, honouring them as emperors and an empress respectively. His mother, Lady Dong, did not become empress dowager and instead received the title of an Honoured Lady.
