五胡乱华
The accession of the Jin [[Jin Huidi|Emperor Hui]] in 290 marked the beginning of the crumbling of the Jin dynasty. Possibly developmentally disabled, he was a puppet of powerful parties which sought to control the Jin court. During the [[Rebellion of the Eight Kings]], all parties in power attempted to wipe out the former rulers by murder, mass executions or battles. Each struggle grew more violent and bloodier than the one before. Not surprisingly, Wu Hu mercenaries were often called upon. Wu Hu chieftains and herdsmen clearly comprehended the selfishness of the nobility and the destruction of the country through their struggle for power and wealth. Coupled with famine, epidemic and floods, cannibalism was observed in some parts of the country only a few years after Emperor Hui's accession. Wu Hu herdsmen saw no reason to obey orders from the Jin court and widespread uprisings soon followed.
