Lü Buwei was a Warring States Period merchant who schemed his way into governing the . He served as Chancellor of China for King Zhuangxiang of Qin, and as regent and Chancellor for the king's young son Zheng, who became Qin Shi Huang, the first Emperor of China. Lü Buwei committed suicide after being implicated in plotting with the Queen Dowager and her "eunuch" lover. Lü notably sponsored an encyclopedic compendium of Hundred Schools of Thought philosophies, the 239 BCE ''Lüshi Chunqiu'' .
History
The primary sources of information about Lü Buwei date from the first century BCE: Sima Qian's ''Records of the Grand Historian'' and 's ''Zhan Guo Ce'' and ''Shuoyuan'' . Since these three Han Dynasty texts openly criticize both Lü and the Qin Dynasty, some alleged stories can be discounted. Note: the following English translations come from John Knoblock and Jeffrey Riegel's scholarly study of the ''Lüshi chunqiu''.
The ''Shiji'' biography of Lü Buwei says he was a native of the state of Wei who became a successful travelling merchant and earned "thousands of measures of gold." In 267 BCE, the first son of King Zhaoxiang of Qin died, and he made his second son, the Lord of Anguo , crown prince. Anguo promoted his concubine Lady Huayang , who was childless, as his primary wife. Anguo had more than 20 sons, and Prince Yiren , one of the middle-ranking ones, was sent as a Qin political hostage to the state of . When Lü was trading in the Zhao capital Handan, he met Yiren and said, "This is a rare piece of merchandise that should be saved for later."
The ''Zhanguoce'' has a story about Lü deciding to change careers from commerce to government.
On returning home, he said to his father, "What is the profit on investment that one can expect from plowing fields?"
"Ten times the investment," replied his father.
"And the return on investment in pearls and jades is how much?"
"A hundredfold."
"And the return on investment from establishing a ruler and securing the state would be how much?"
"It would be incalculable."
"Now if I devoted my energies to laboring in the fields, I would hardly get enough to clothe and feed myself; yet if I secure a state and establish its lord, the benefits can be passed on to future generations. I propose to go serve Prince Yiren of Qin who is hostage in Zhao and resides in the city of Jiao."
Using Machiavellian bribes and machinations, Lü arranged for Yiren to return home and be adopted as the son and heir of Lady Huayang. She changed his name to Prince Chu because she was from the southern state of .
The ''Shiji'' says Lü had a beautiful "dancing girl" in his household, with whom Chu became so infatuated that he asked for her. Lü reluctantly presented his courtesan to the prince, and they returned to Handan. In 259 BCE, she had a son named Zheng , who eventually unified China and became the first Emperor Qin Shi Huang. The ''Shiji'' alleges that the biological father was Lü not Chu. After the death of King Zhaoxiang, Anguo was enthroned as King Xiaowen of Qin, but he died after a reign of only three months . His widow Huayang became Queen Dowager, and her adopted son, Prince Chu became King Zhuangxiang of Qin in 250. He appointed Lü Buwei as Prime Minister or Chancellor of China and enfeoffed him with "an income of 100,000 households in Luoyang." Lü consolidated power in Qin and oversaw several military conquests of neighboring states. When King Zhuangxiang died in 247 BCE, the 13-year-old Prince Zheng was enthroned. He reappointed Lü as Chancellor and called him "Uncle".
As chancellor and regent, Lü dominated the Qin government and military. He invited famous scholars from all over China to the Qin capital Xianyang, and they compiled an encyclopedic compendium of early Chinese philosophical systems, the ''Lüshi Chunqiu'' .
The ''Shiji'' says the Queen Dowager pursued many illicit sexual activities, and Lü,
fearing that discovery would cause disaster to befall him, secretly sought a man with a large penis, Lao Ai , whom he made his retainer. Sometimes he would have music performed and order Lao Ai to put his penis through a wheel of paulownia wood and walk about, making certain that the queen dowager would hear about it to entice her. The queen dowager did hear about it and consequently secretly desired to obtain him. Lü Buwei thereupon introduced Lao Ai to her. Deviously ordering someone to accuse Lao Ai of a crime punishable by castration, Lü also privately told the queen dowager, "If we can fake the castration, we can make him a servant in the harem." The queen dowager therewith covertly gave a generous bribe to the officer charged with castrations to falsely sentence him and to pluck out his eyebrows and beard to make him appear a eunuch. As a result, he was made a servant of the queen dowager.
The queen fell in love with Lao and had him appointed Marquis of Shanyang. After she became pregnant, he recklessly took control of the Qin government.
The ''Shuoyuan'' says,
Lao Ai had sole power over the affairs of state and grew increasingly arrogant and extravagant. The high officials and honored ministers of government all drank and gambled with him. Once when he got drunk, he began to speak belligerently. In a provocative fashion, eyes glaring with anger, he bellowed" "I am the stepfather of the emperor. How dare some wretch oppose me!" One of those with whom he had quarreled ran to report this to the emperor, who was outraged.
The emperor learned that Lao Ai was not really a eunuch, and had plotted with the queen to make their illegitimate son become successor. After an attempted 238 BCE revolt failed, the queen was exiled and Lao Ai was executed, along with three generations of his relatives, including their two sons who were put into sacks and beaten to death. Rather than execute the influential Lü, the emperor demoted and banished him to . Lü feared eventual execution and "drank poison" in 235 BCE. As a result of the Lao Ai affair, the emperor removed power from most of Lü Buwei's foreign scholars and restored it to the hereditary Qin aristocracy. After his death, the Lüshi Chunqiu fell out of favor with the Qin Empire, but was resurrected by the Qin's long-lived successor, the Han Dynasty.
Koblock and Riegel describe the Western and Chinese historical perspectives of Lü Buwei.
Lü engineered the succession of a minor prince to the throne of Qin; and when that prince died after a few months on the throne, Lü became regent for his young son, the future First Emperor of Qin. In the West, we would regard Lü as a merchant-prince, a patron of culture and literature, an eminent statesman and wise counselor, a kind of Medici prince who influenced not merely Florence and Italy, but all of European civilization. But in China the facts of Lü's life, together with the fact that he was from the despised merchant class, condemned Lü in the eyes of the Han literati. They considered Qin and its unification of China an unmitigated evil. So Lü was in their eyes a parvenu and a fraud whose schemes had made possible Qin's evil. He was a baleful figure, richly deserving of condemnation and eminently worthy of ridicule and calumny.
