Empress Chu Suanzi

Chu Suanzi, formally Empress Kangxian, at times as Empress Dowager Chongde (崇德太后), was an empress of Jin Dynasty (266–420). Her husband was Emperor Kang, and, outliving him by 40 years, she was an empress dowager during the reigns of five emperors, including serving as regents for three of them: her son Emperor Mu (344–357), her nephew Emperor Ai (364–366), and her cousin Emperor Xiaowu (373–376). Despite the power she held, she appeared to largely yield to the judgement of high-level officials who advised her and rarely made decisions on her own.
