Reasons for the demise of ancient dynasties

The replacement of dynasties is one of the important phenomena of social structure adjustment in China feudal society. In the process of autocratic imperial power, there will inevitably be problems such as king rebellion, consorts monopolizing power, powerful ministers usurping the throne, eunuchs chaotic politics, and separatist regimes in buffer regions. Domestic rebellion is accompanied by foreign invasion and domestic peasant uprising. In the late dynasty, faced with land annexation, the poorer and poorer, the richer and richer, the Matthew effect appeared, and many social contradictions were difficult to adjust.

Faced with vested interests such as civil servants, military commanders, relatives and relatives, what the ruling emperor can do is to improvise, maintain a reluctant balance among all parties, and strive to make the feudal dynasty operate in an orderly manner. Until the contradiction became more and more serious, only one accidental factor was needed to ignite the fuse, and a seemingly solid feudal dynasty building completely collapsed.
