Shunzhi Emperor
Hong Taiji died on 21 September 1643 and was succeeded by Fulin, who was enthroned as the Shunzhi Emperor. Bumbutai, as the mother of the reigning emperor, was honoured with the title "Holy Mother, Empress Dowager" with honorary name "Zhaosheng". Her aunt Jerjer, as the empress consort of the previous emperor, was similarly honoured as "Mother Empress, Empress Dowager". Hong Taiji's younger half-brother, Dorgon, was appointed as Prince regent to rule on behalf of the Shunzhi Emperor until the emperor reached adulthood. After Dorgon died on 31 December 1650, the Shunzhi Emperor posthumously stripped him of his princely title and had his dead body exhumed and mutilated. It is believed – though not supported by historical evidence – that Empress Dowager Zhaosheng secretly married Dorgon after Hong Taiji's death, since levirate marriage was common among Mongols.
