Although his support had been essential to Shunzhi's ascent, Dorgon had centralised so much power in his hands as to become a direct threat to the throne. So much so that upon his death he was bestowed the extraordinary posthumous title of Emperor Yi (), the only instance in Qing history in which a Manchu "prince of the blood" () was so honored. Two months into Shunzhi's personal rule, however, Dorgon was not only stripped of his titles, but his corpse was disinterred and mutilated. to atone for multiple "crimes", one of which was persecuting to death Shunzhi's agnate eldest brother, Hooge. More importantly, Dorgon's symbolic fall from grace also led to the purge of his family and associates at court, thus reverting power back to the person of the emperor. After a promising start, Shunzhi's reign was cut short by his early death in 1661 at the age of 24 from smallpox. He was succeeded by his third son Xuanye, who reigned as the Kangxi Emperor.
