Officials led by Yuan He, Baba Kehou (拔拔渴侯), Dugu Ni (獨孤尼), and Buliugu Li rose against Zong and killed him, making Tuoba Jun emperor, and Tuoba Jun, after he took the throne as Emperor Wencheng, posthumously honored Tuoba Huang as an emperor.

In 452, he was assassinated by his eunuch Zong Ai, who claimed that, by her orders, Emperor Taiwu's son Tuoba Yu the Prince of Nan'an should be made emperor, bypassing Emperor Taiwu's apparent intended heir, Tuoba Jun, the son of Tuoba Huang the Crown Prince, who had died in 451.
Zong subsequently assassinated Emperor Taiwu and Tuoba Huang's younger brother Tuoba Yu (whom he had briefly made emperor) in 452, and then was overthrown by high-ranking officials, who made Tuoba Jun emperor (as Emperor Wencheng).
