Complete chronology

-291

Merchant in a Warring World

Lu Buwei's rise was unusual because he did not begin as a hereditary prince or battlefield commander. He was remembered as a wealthy merchant who understood value in political as well as commercial terms. The Warring States world created opportunities for men who could move between courts, use wealth strategically and read the ambitions of rulers. Qin's royal politics offered one such opening. Hostage arrangements between states placed princes in vulnerable positions far from home. Lu Buwei saw that a neglected Qin prince in Zhao could become far more than a stranded royal: he could become an investment in the future of the strongest state in China.

-260s

Backing Yiren

Yiren, a Qin prince held in Zhao, did not initially look like the obvious heir to Qin. Lu Buwei used wealth, persuasion and court connections to improve Yiren's prospects, especially through relationships inside the Qin royal household. The later story is layered with gossip and political suspicion, including rumours about King Zheng's parentage that should be handled cautiously. The secure political point is dramatic enough: Lu Buwei helped transform Yiren's position and was rewarded when Yiren eventually became King Zhuangxiang of Qin. A merchant had entered the highest level of Warring States politics by turning dynastic vulnerability into opportunity.

Chancellor of Qin

King Zhuangxiang's reign was brief, but Lu Buwei's influence remained. When Zheng became king as a young teenager in 247 BC, Lu Buwei stood near the centre of government. Qin was already the strongest Warring State, with institutions hardened by generations of reform and war. The regency years demanded continuity. Armies still campaigned, administration continued and rivals watched for weakness. Lu Buwei's authority helped steady the court, but it also made him a potential obstacle once Zheng matured. A young king who intended to rule directly could not forever tolerate a minister whose networks, reputation and past favours made him almost a second centre of gravity.

-239

The Annals of Lu Buwei

Lu Buwei was not only a court manager. He also sponsored intellectual production, most famously the Lushi Chunqiu, or Annals of Lu Buwei. The work gathered ideas from the rich argumentative world of the late Warring States period, when thinkers debated rulership, seasons, ritual, law, diplomacy and cosmic order. That patronage shows a different side of Qin politics. The state is often remembered only for Legalist severity, but its court also attracted advisers and texts. Lu Buwei's project suggested that government required broad knowledge as well as command. In hindsight, it also marks a road Qin did not fully take after Zheng's personal rule hardened.

-238 to -235

Fall From Power

In 238 BC, a rebellion connected with Lao Ai and the queen dowager gave King Zheng the chance to crush rival court factions. Lu Buwei was implicated by association and lost the trust that had protected him. He was removed from power, later ordered away from the capital region and died by suicide in 235 BC. His fall cleared the path for Zheng's full personal authority and the final campaigns of conquest. Lu Buwei's life therefore sits just before the empire begins: he was crucial to the political world that produced King Zheng, yet he did not survive to shape the imperial order that Zheng created.
