When Liu Bang was still the head of the Surabaya Pavilion in Pei County, he had a group of well-connected buddies around him, such as Fan Duo, Xiao He, Cao Shan, Xiahou Baby and so on. Later, these people followed Liu Bang to rebel against Qin, established the Western Han Dynasty, and became the founding heroes. Among these brothers of Liu Bang, the one who had the best relationship with him was Lu Xie, who was even closer than his brother. However, Lu Xie betrayed Liu Bang and led his army to surrender to the Xiongnu.
When Liu Bang rebelled against Qin, he was wanted by the government for his affairs, and Lu Xuan followed Liu Bangdong to hide in Tibet. After Liu Bang arrived in Hanzhong, Lu Xie was made a general, and when Chu and Han exchanged troops, Lu Xie appointed a lieutenant, accompanied by Liu Bang, and Liu Bang's palace Lu Xuan came and went freely, and once Liu Bang made Lu Xie the Marquis of Chang'an, Liu Bang's men were no match for Lu Xie's favor.
In 202 BC, after Liu Bang destroyed Xiang Yu, he took Lu Xie to conquest Zang Di, the King of Yan, and after the King of Yan surrendered, Liu Bang made Lu Xie the King of Yan. However, in the eleventh year of Gaozu, Lu Xuan announced a rebellion, which was a great blow to Liu Bang. Why did Lu Qi rebel?
In the autumn of 197 BC, Chen Xi rebelled in Daidi, Liu Bang led his troops to attack Chen Xi, and the Yan king Lu Xian sent troops to attack the northeast of Chen Xi, at this time, Chen Xi asked the Xiongnu for help, and Lu Xian also sent his subordinate Zhang Sheng to envoy the Xiongnu, hoping to prevent the Xiongnu from helping Chen Xi. After Zhang Sheng arrived at the Xiongnu, the son of the former King of Yan saw Zhang Sheng and said: "The reason why the Yan kingdom can exist for a long time is because the princes have rebelled many times and the wars have been continuous for many years, so that the Yan kingdom has survived, and you don't want the Yan kingdom to be destroyed as soon as possible, so you have to make peace with the Xiongnu and make the wars between the princely states continue for many years." ''
Zhang Sheng went back to tell Lu Xian that Lu Xian felt justified, so he asked Zhang Sheng to be a spy and secretly went to Chen Xian to discuss maintaining the war. In the twelfth year of the Han Dynasty, Liu Bang sent Fan Huan to attack Chen Xi and behead him, and after Chen Xi's deputy generals surrendered to Liu Bang, they told Liu Bang about the exchange of information between the King of Yan and Chen Xi. Liu Bang sent emissaries to summon Lu Xie into Beijing, Lu Xie said that he was sick and did not dare to go, Liu Bang sent Yu Shi Dafu to greet him, and by the way to inquire about the case, Lu Xie was even more frightened, closed the door, and said to his favorite subjects: ''The only ones with different surnames who have been crowned kings are me and Wu Rui, the king of Changsha, last spring, The Marquis of Huaiyin, Han Xinmanmen, was killed, and peng Yue was killed, all of which were done by Lü Hou, and now that the emperor is seriously ill, the state affairs are in charge of Lü Hou, and Lü Hou always finds an excuse to kill the king and the hero of the different surnames. Therefore, he still said that he was sick and refused to enter Beijing.
Later, without an impermeable wall, the Han Dynasty captured some surrendered Xiongnu, who said that Zhang Sheng fled to the Xiongnu as an emissary of the Yan state, and Liu Bang thought that Lu Xian had rebelled. Liu Bang sent Fan Duo and Zhou Bo to attack the State of Yan, and Lu Xie led his family and subordinates to flee into the Xiongnu, making him the King of Eastern Hulu. However, the good times did not last long, and he fell seriously ill and died for more than a year, ending up with a guest dying in a foreign country.
To sum up, Lu Xie did not want to end up with a tragic death in order to protect himself, and the reason why he rebelled was because of the tragic deaths of Han Xin and Peng Yue, which made Lu Xie even more afraid that there would be an ending for Han Xin peng Yue. Forced to turn to the Xiongnu and steal his life, Liu Bang rebelled against him for the sake of his imperial power, and he could not say that in the face of interests, he was cruel and ruthless for himself
