Brief discussion on the cause of social split in the late period of Eastern Han Dynasty

Eastern Han Dynasty was a period of the first great unification in China's feudal society.Both feudal politics and economics were developed greatly.But during the period of late Eastern Han Dynasty,social split occurred.In this essay,I hold that the main reason for the split of the late Eastern Han Dynasty was the strange development of the economy of the farms of the strong landlords.This development made Eastern Han Dynasty,though it was still a unified feudal dynasty,far from as strong as the center power state of Western Han Dynasty.At last,it led to the split and turbulence in the period of late Eastern Han Dynasty.
