Lü Buwei

Lü Buwei (291–235 BCE) was a Warring States period Chinese merchant and eventual late pre-imperial Qin state Chancellor. Originally an influential merchant from the Wei () state, Lü Buwei met and befriended King Zhuangxiang of Qin, who was then a minor prince serving as a hostage in the Zhao state. Through bribes and machinations, Lü Buwei succeeded in helping King Zhuangxiang become the heir apparent to the Qin throne.

After King Zhuangxiang ascended the throne following the death of his father, King Xiaowen, he appointed Lü Buwei as his chancellor () in 249 BCE, and ennobled him as "Marquis Wenxin" (). After King Zhuangxiang's death in 247 BCE, Lü Buwei became the chancellor and regent to King Zhuangxiang's young son, Ying Zheng, who later became Qin Shi Huang (First Emperor of the Qin dynasty).

In 235 BCE, after being implicated in a scandal involving the Queen Dowager Zhao (Ying Zheng's mother) and her illicit lover Lao Ai, Lü Buwei was stripped of his posts and titles and was banished to the remote Shu region in the south of Qin. While in exile, Lü Buwei committed suicide by consuming poison. Apart from his political career, Lü Buwei is also known for sponsoring the Lüshi Chunqiu, an encyclopaedic compendium of the ideas of the Hundred Schools of Thought that was published in 239 BCE.
