[Why] As early agriculture developed and private property emerged, the traditional abdication system could no longer accommodate the power distribution of a stratified society. Power struggles within the tribal confederation intensified and the hereditary impulse grew visible. [What] After Yu's death, Qi used his consolidated political and military strength to definitively break the abdication custom. He defeated the eastern tribes who still championed abdication and proclaimed the formal establishment of hereditary monarchy. [Who] Qi was the core driver of the transformation, using ironclad means to entrench his rule. The conservative faction led by Boyi defended abdication fiercely but ultimately lost the contest of power. [How] This shift marked the great leap of Chinese political organization from shared rule to family rule and instituted the dynastic autocracy that endured for millennia. The Xia became the first hereditary dynasty in Chinese history, formally taking center stage.

By establishing this moral or administrative benchmark, it continues to shape the structural and philosophical fabric of ancient Chinese statecraft.
