The 7th year of the Empress Gao(181 B.C. continued)
Chen Ping was worried about the growing power of the Lü clan and feared he might be implicated in their downfall. While Chen Ping was preoccupied with these thoughts, Lu Jia came to see him and sat down without being invited. Chen Ping didn’t even acknowledge him.
Lu Jia asked, “What is troubling you so deeply?”
Chen Ping replied, “What do you think is troubling me?”
Lu Jia said, “You are extremely wealthy and have no further desires. But you are concerned about the Lü clan and the young emperor.”
Chen Ping agreed, “Yes, that’s it. What can I do about it?”
Lu Jia said, “When the world is at peace, the focus is on the ministers. When the world is in chaos, the focus is on the generals. When ministers and generals are in harmony, the people will follow. Even if significant events occur, power will not be divided. The balance of state power is held by two gentlemen. I often wanted to advise the Marquis of Jiang on this, but he always joked and dismissed my advice. Why don’t you befriend the Marquis of Jiang and form a deep bond with him?”
Lu Jia then laid out plans targeting the Lü clan to Chen Ping. Following his advice, Chen Ping gave the Marquis of Jiang 500 gold coins as a birthday gift and hosted a lavish feast. The Marquis of Jiang responded in kind, and the two became close friends. As their friendship grew, the power of the Lü clan began to decline. In gratitude, Chen Ping gave Lu Jia 100 house slaves, 50 carriages, and five million coins to cover his expenses for food and drink.
The Empress Dowager sent messengers to inform the Prince of Dai, Liu Heng, of her intention to relocate him to the principality of Zhao. The Prince of Dai expressed his gratitude but requested to remain guarding the borders of Dai. The Empress Dowager then appointed her nephew, Lü Lu, as the new Prince of Zhao and posthumously honored Lü Lu’s father, Lü Shizhi, Marquis Kang of Jiancheng, as Prince Zhao of Zhao.
In September, the Prince of Yan, Liu Jian, passed away, leaving behind a son born to a concubine. The Empress Dowager ordered the son to be killed, bringing an end to the Principality of Yan.
The Empress Dowager also sent the Marquis of Longlü, Zhou Zao, on a campaign against Nanyue.
The 8th year of the Empress Gao(180 B.C.)
In winter, on October 12, the Marquis of Dongping, Lü Tong, the son of Prince Su of Lü, was appointed Prince of Yan, while his younger brother, Lü Zhuang, became the Marquis of Dongping.
In March, the empress dowager performed an exorcism ritual. On her return journey, as she passed through Zhidao Post, she encountered a creature resembling a gray dog, which bit her under the arm before vanishing. Divination revealed that the ghost of the Prince of Zhao—Liu Ruyi, was responsible for this, leading to the empress dowager’s illness and pain in her armpit.
The empress dowager’s grandson, Zhang Yan, the Prince of Lu, was still young and frail. Therefore, on April 15 in the summer, she appointed Zhang Ao‘s two sons, Zhang Chi and Zhang Shou—both born of his concubine—as the Marquises of Xindu and Lechang, respectively, to assist the Prince of Lu. She also awarded the title of Marquis of Jianling to Director of Internuncio Zhang Shi, an eunuch, for his counsel in elevating the Lü clan to kingship.
The Yangtze and Han Rivers overflowed, flooding more than ten thousand households.
In July of autumn, as the empress dowager’s illness worsened, she appointed Lü Lu, the Prince of Zhao, as the top general to command the Northern Army, while Lü Chan, the Prince of Lü, was given command of the Southern Army. She exhorted them both, saying, “When the Lü clan was elevated to kingship, the ministers were not fully in accord. I fear that after my death, with the emperor still young, the ministers may stage a coup. You must seize control of the Palace Guards and ensure you are not distracted by the funeral procession, lest you lose grip of the army!”
On July 30, the empress dowager passed away, leaving a will that pardoned all criminals in the empire. Lü Chan, Prince of Lü, was appointed Chancellor of State, and Lü Lu‘s daughter was made empress. After Empress Gao‘s burial, Left Chancellor Shen Yiji was appointed Grand Tutor to the emperor.
The Lü clan plotted to take action, but hesitated due to fear of powerful ministers like the Marquis of Jiang, Zhou Bo, and the Marquis of Yingyin, Guan Ying. The Marquis of Zhuxu, Liu Zhang, who had married Lü Lu‘s daughter, learned of their plan and secretly informed his elder brother, Liu Xiang, the Prince of Qi. He warned that the Lü clan was preparing to act and suggested launching an attack towards the west, with the Marquis of Zhuxu and the Marquis of Dongmou as allies within the capital, to overthrow the Lü clan and enthrone the Prince of Qi as emperor.
The Prince of Qi, along with his maternal uncle Si Jun, the Lord of Chamberlain Zhu Wu, and Commandant of the Central Guard Wei Bo, secretly conspired to launch the attack. However, the Prime Minister of Qi, Shao Ping, disapproved of the plan. In August, the Prince of Qi decided to have Shao Ping killed, but when Shao Ping discovered this, he sent troops to besiege the palace. Wei Bo deceived Shao Ping, “The Prince wished to mobilize troops but lacked the proper authorization from the Han Dynasty’s tiger tally. You did the right thing to surround the prince’s palace. I volunteered to lead the troops to put the Prince of Qi under house-arrest.” Shao Ping believed him and authorized him to lead the troop, and Wei Bo then surrounded Shao Ping’s residence, prompting Shao Ping to commit suicide.
As a result, Si Jun became the Prime Minister of Qi, Wei Bo was appointed general, and Zhu Wu became Minister of Interior. They then mobilized the state’s military forces.
Zhu Wu was sent to deceive Liu Ze, the Prince of Langya, saying: “The Lü clan has rebelled, and the Prince of Qi has dispatched troops to the west to exterminate them. Since the Prince of Qi is young and inexperienced in military affairs, he wishes to entrust the country to Your Majesty. As a general under Emperor Gaozu, Your Majesty’s presence in Linzi is requested to discuss matters with the Prince of Qi.”
Believing this, the Prince of Langya hurried west to meet the Prince of Qi, but upon arrival, he was detained. Zhu Wu then mobilized and led the Langya army. The Prince of Langya advised the Prince of Qi, saying: “Your Majesty, as Emperor Gaozu‘s grandson, you are the rightful heir to the throne. However, the court officials are hesitant and have not yet made a decision. Among them, I, Liu Ze, have served the longest and am the most respected, and the officials are awaiting my judgment. Keeping me here would be meaningless. Allow me to return to the court and deliberate with the ministers.”
The Prince of Qi agreed and sent the Prince of Langya on his way with additional carriages. Once the Prince of Langya departed, the Prince of Qi raised an army and attacked Jinan to the west, which had become part of the Lü state. He also sent letters to various princes, outlining the Lü clan’s crimes and proposing that they raise troops to exterminate them.
Chancellor Lü Chan learned of the Prince of Qi‘s campaign and sent the Marquis of Yingyin, Guan Ying, to attack the Prince of Qi. However, when Guan Ying reached Xingyang, he had second thoughts: “The Lü clan has a strong military presence in Guanzhong and intends to threaten the Liu family and establish themselves as rulers. If I defeat Qi and return, it will only strengthen the Lü clan’s position.” He decided to remain where he was and sent envoys to meet with the Prince of Qi and other princes, intending to wait for the Lü clan to overthrow the Liu dynasty, and then crush them.
The Prince of Qi, learning of Guan Ying‘s plan, decided to return to the western border and wait for the Lü clan’s next move.
Lü Lu and Lü Chan wanted to revolt, but they hesitated, fearing not only the Marquis of Jiang, the Marquis of Zhuxu, and others within the court, but also the armies of Qi and Chu outside. They were also concerned that Guan Ying might defect to the other side. They hoped to wait until Guan Ying‘s forces clashed with those of Qi before launching their rebellion, but they remained indecisive.
At that time, Liu Tai, the Prince of Jichuan; Liu Wu, the Prince of Huaiyang; Liu Chao, the Prince of Changshan; and Zhang Yan, the Prince of Lu, were all still young and had not yet departed for their respective kingdoms. They resided in Chang’an. Lü Lu, the Prince of Zhao, and Lü Chan, the Prince of Liang, commanded the northern and southern armies, respectively, and were the primary leaders of the Lü clan. None of the other marquises or ministers felt assured of their safety or were firmly committed to any particular course of action.
The Grand Commandant, Marquis of Jiang, could not command the army directly. The Marquis of Quzhou, Li Shang, was old and in poor health, and his son, Li Ji, was a friend of Lü Lu. The Marquis of Jiang conspired with Chancellor Chen Ping and arranged for someone to abduct Li Shang, then compelled Li Ji to deceive Lü Lu by saying: “Emperor Gaozu and Empress Lü jointly established the empire, and the nine princes from the Liu clan, along with the three princes from the Lü clan, were all appointed based on the ministers’ counsel. This has been communicated to the princes, and they all support it.”
“Now that the empress dowager has passed away and the emperor is young, you, as the Prince of Zhao, are carrying the royal seal but are not defending the state’s borders. Instead, you are acting as chief commander and keeping your army here, which is raising suspicion among the ministers and princes. Why not return the seal of commander-in-chief and entrust your army to the Grand Commandant? Also, let the Prince of Liang return the chancellor’s seal, make a pact with the ministers, and then return to your princedoms. This will force the Qi army to withdraw, and the ministers will feel secure. You can then enjoy ruling a vast princedom, securing the prosperity of your descendants for generations.”
Lü Lu believed in this plan and considered handing over his army to the Grand Commandant. He sent word to Lü Chan and the other senior members of the Lü clan. Some thought it was a good idea, while others disagreed, leaving the plan unimplemented.
Lü Lu trusted Li Ji and was out hunting with him when they happened to pass by his aunt, Lü Xu. She became furious and said, “If you, as a commander, abandon your troops, the Lü family will have no place to survive!” In her anger, she threw all her pearls and valuables onto the floor, exclaiming, “I don’t want to keep them for others!”
On September 10, the Marquis of Pingyang, Cao Zhu, acting as Grand Master of the Censorate, visited Chancellor Lü Chan to discuss state affairs. During the meeting, Jia Shou, the Grand Chamberlain and an emissary back from Qi, reproached Lü Chan, saying, “As the Prince of Liang, you should have reported to your principality earlier. Now that you want to leave, is it still possible?” He then revealed Guan Ying’s plan to execute the Lü family with the assistance of the Princes of Qi and Chu, urging Lü Chan to enter the palace immediately.
The Marquis of Pingyang overheard this and rushed to inform Chancellor Chen Ping and Grand Commandant Zhou Bo.
The Grand Commandant attempted to enter the Northern Army but was denied access. The Marquis of Xiangping, Ji Tong, was in charge of the imperial tally. Marquis of Jiang ordered him to hold the tally and falsely claimed that the emperor had authorized the Grand Commandant to enter the Northern Army on an urgent matter. The Grand Commandant then had Li Ji and the Grand Herald, Liu Jie, persuade Lü Lu, saying, “The Emperor has appointed the Grand Commandant to lead the Northern Army and wants you to return to your princedom. You should hand over your command seal and leave immediately, or disaster will follow soon.”
Lü Lu, trusting Li Ji, believed he wouldn’t lie and handed over his seal to the Grand Herald, entrusting his troops to the Grand Commandant. By the time the Grand Commandant arrived at the army, Lü Lu had already departed. Upon entering the army gate, the Grand Commandant commanded the soldiers, “Those who support the Lü clan should bare their right arms and shoulders, and those who support the Liu clan should bare their left arms and shoulders.” The soldiers all bared their left arms and shoulders, and the Grand Commandant took control of the Northern Army.
However, the Southern Army remained intact. Prime Minister Chen Ping summoned the Marquis of Zhuxu, Liu Zhang, to serve as the Grand Commandant’s assistant and ordered him to guard the army camp gate. Meanwhile, the Marquis of Pingyang, Cao Zhu, instructed the Commandant of the Court Guards not to allow Chancellor Lü Chan to enter the palace.
Lü Chan, unaware that Lü Lu had already left the Northern Army, entered Weiyang Palace with the intention of starting a rebellion. Denied entry at the palace gate, he anxiously paced back and forth. The Marquis of Pingyang, fearing he would not be able to stop Lü Chan, rushed on horse to warn the Grand Commandant. The Grand Commandant, wary of the Lü family’s influence and hesitant to openly call for their execution, instructed the Marquis of Zhuxu, “Hurry and protect the Emperor in the palace!”
Marquis Zhuxu requested soldiers, and the Grand Commandant provided him with over a thousand troops. They entered Weiyang Palace and found Lü Chan in the court.
In the late afternoon, they launched an attack on Lü Chan, forcing him to flee. A strong gust of wind suddenly blew, causing Lü Chan’s subordinates to panic and lose their ability to fight back. Lü Chan was chased down and killed in the latrine of the Grand Chamberlain’s office. After Lü Chan‘s death, the Emperor ordered an internuncio to present the imperial tally as a token of appreciation to Marquis of Zhuxu.
Marquis of Zhuxu attempted to take the tally, but the internuncio refused. Determined, Marquis of Zhuxu boarded the same wagon as the internuncio and rushed to the palace with the tally, beheading Lü Gengshi, the guard captain of ChangLe Palace, along the way.
Marquis of Zhuxu, after taking care of the palace, hurried back to the Northern Army to report to the Grand Commandant. The Grand Commandant congratulated him, “Our only concern was Lü Chan. Now that he has been executed, there will be no more problems in the empire!” He then ordered the arrest of all members of the Lü clan, men and women alike, and had them executed, regardless of age.
On September 11, Lü Lu was arrested and executed, Lü Xu was whipped to death, and Lü Tong, the Prince of Yan, was executed. Zhang Yan, the Prince of Lu, was deposed.
On September 18, the Prince of Jichuan(Liu Tai) was promoted to Prince of Liang. Marquis of Zhuxu was then dispatched to inform the Prince of Qi about the extermination of the Lü clan and was ordered to stop further military actions.
