The rebellion of Wu Chu and seven kings occurred in a rebellion of a vassal state in the third year of Emperor Jing of Han Dynasty (BC 154). The kings of the seven countries involved in the rebellion were Wu, Chu, Zhao Wangsui, Ji Biguang, Zichuan, Jiaoxi and Jiaodong Wangxiongqu. Wu is the mastermind of this rebellion. The bloodline relationship of the Seven Kings is as follows: The root of the rebellion of the Seven Kingdoms is the contradiction between the powerful kingdom power and the autocratic imperial power. Political events such as Zhu Lu's coming to power and Liu Heng's succession aggravated this contradiction. The fuse of the Seven Kingdoms Rebellion was that Liu Qi, Emperor Wu of the Han Dynasty, adopted Chao Cuo's "policy of reducing vassals" and cut off the land of the kingdom. The powerful situation of the kingdom was formed by Emperor Gaozu Liu Bangshi. At the stage of the struggle between Chu and Han, Liu Bang was forced by the situation to enfeoffment Wang with a different surname. After Liu Bang proclaimed himself emperor in the fifth year (202 BC), there were seven kings with different surnames (see different surnames). Except Wu Rui, the king of Changsha, he wiped out six people. He believes that Qin Zuo was short because Qin did not enfeoffment his children, so he enfeoffment his brothers and sons and nephews as kings with different surnames, that is, nine kings with the same surname. High-impedance and ministers * * * vowed that Liu was not the king. In the early Han dynasty, the vassal States with the same surname had vast land and numerous accounts. Because the king with the same surname is closely related to his ancestors, loyal to the Han Dynasty and plays the role of guarding the central government, the problem of weak branches is not prominent at this time. After the death of Emperor Gaozu, Lv Hou, who was in power, broke his oath and made Zhu Lu king. Lv Hou had strict control over the high-impedance philosophers who were named kings, and some kings were even wiped out to death. King Qifei is the eldest son of Gaozu, with a prominent position. Although Lv Hou has doubts about him, it is difficult to deal with him. Princess Luyuan, the daughter of the King of Qi, offered sacrifices to Chengyang County and Lv Hou, and actively adjusted the relationship with Lv Hou so that they could live in peace. Lv Hou's autocratic power and the enfeoffment of Zhu Lu aroused strong opposition from the kings of Liu, and the contradiction between kingship and imperial despotism was manifested in the combination of Liu and the kings against Lu. After Lv Hou's death, Lv Jubing prepared to launch a coup. At that time, Qi's son, Zhu, and Dong Mouhou all lived in Chang 'an. They secretly made an appointment with their brother, the King of Qi, and led the troops into the customs. When Zhu Lu was destroyed, the general Lu would inherit the throne. Liu will arise, and Chang 'an will send general Guan Ying to attack. Guan Ying stationed troops in Xingyang, made an appointment with Liu, and prepared to attack various roads. At this point, Liu Zhang joined forces with Qiu He, the prime minister in Chang 'an, and eliminated Zhu Lu's influence. The ministers think that the Bo family is more reliable, and it is estimated that there will be no serious problems like Zhu Nongquan. So the agreement was reached, and the king of Qi was about to be defeated.
