After the fall of the Qin Dynasty, Xiang Yu divided the world, and there was a short period of tranquility in the world, and among the 18 princes were the descendants of the Six Kingdoms such as Wei Bao, the king of Western Wei, and Tian shi, the king of Jiaodong, the descendants of the Qin Dynasty such as The Yong King Zhang Handan and the Sai King Sima Xin, and the Haojie who was the King of Jiujiang, Yingbu, and the heroes had their own origins.
Tian Rong then killed the Three Qi Kings (Xiang Yu's princes Jiaodong, Jibei, and Qi), established himself as the King of Qi, and gave Peng Yue the seal of general. Chen Yu borrowed troops to defeat Zhang Er, the king of Changshan, and Honored Xiang Yu's title of Zhao Xie as the King of Zhao, and the King of Zhao made Chen Yu the Acting King. Liu Bang destroyed the Three Qin Kings (Xiang Yu's titles of King Yong, King Sai, and King Zhai), captured Guanzhong, and in the name of Revenge by Emperor Yi, gathered the combined forces of the Five Roads princes to jointly negotiate with Xiang Yu.
Liu Bang, who had recruited his son and infant and failed to obtain the title of King of Guanzhong, was renamed king of Han by Xiang Yu. Liu Bang had no way, and did not dare to openly contradict Xiang Yu, and he was still respectful and afraid of Xiang Yu. So at that time, he packed up and took a group of his own advisers and soldiers to Hanzhong to become the king of Han. After entering Hanzhong, he also burned the boardwalk, indicating that he would be the king of Han who would keep to himself. At this time, Liu Bang had lost his ambition to compete for the world, because he occupied the land of Bashu, and Liu Bang did not have the strength to compete with Xiang Yu. Among the various princes who were divided, why did only Liu Bang dare to compete with Xiang Yu for the world?
First of all, Liu Bang had many military generals and strategists under his command
The Battle of Julu Xiang Yu pit killed hundreds of thousands of Qin troops, although it made him powerful for a while, but the world recognized Xiang Yu's cruel and unkind side. On the other hand, Liu Bang, by summoning the Prince of Qin, showed his benevolent demeanor. At this time, Han Xin, who was serving under Xiang Yu and had repeatedly introduced himself, was not appreciated by Xiang Yu. So Han Xin came to Liu Bang's command through the introduction of Xiahou Bao and Xiao He. Under the advice of Zhang Liangxiao and others, Han Xin boasted to Liu Bang about Haikou. So Liu Bang regained his strength and wanted to compete with Xiang Yu for the world. At this time, Liu Bang did not know whether his future self could unify the world, but Xiang Yu's suppression of himself made him have the idea of retaliating against the other party.
Liu Bang made Han Xin a great general, and he opened the curtain on the Shu han struggle for hegemony. At this time, Tian Rong of the Northern Lands took the lead in standing up against Xiang Yu, because Qi Di bordered Chu Di. Tian Rong's actions brought Great Pressure to Xiang Yu. Therefore, at this time, Xiang Yu did not have the energy to take care of the western battlefield. Therefore, Liu Bang took this opportunity to let Han Xin command the army to defeat the Yong King, the Sai King, and the Zhai King successively. Liu Bang, who recaptured the land of Guanzhong, subsequently played the banner of avenging the Yi Emperor. The people of Guanzhong were grateful for Liu Bang's benevolent act of recruiting his sons and babies, and they supported him immensely, and the banner of avenging the Righteous Emperor made Liu Bang form an alliance with some princes. In this way, Liu Bang formed a coalition of 560,000 troops and directly attacked the Chu capital Pengcheng.
Second, Liu Bang had a moral advantage that others did not have
In stark contrast to the brutal and fierce Xiang Yu, Liu Bang gained a good reputation for benevolence and love for the people, which gave him a favorable position in the rebel army. When dividing the army to destroy Qin, King Huai of Chu sent Xiang Yu to gnaw hard bones to save the siege of Handan. Liu Bang lived up to the expectations of the people, fought all the way, broke through the Daodaoxiong Pass, and finally conquered Xianyang, realizing the long-cherished wish of the people of the world to destroy Qin. King Huai of Chu had an appointment with various rebel armies--whoever defeated the Qin state first and invaded Xianyang would make him the king of Guanzhong, and Xiang Yu refused to follow the instructions of king Huai of Chu and made Liu Bang the king of Guanzhong, but instead divided Liu Bang into distant Bashu, but divided the Qin land into three and gave it to Zhang Handan and others. It should be known that Zhang Handan and others were not only the executioners who killed Xiang Chen Shengliang to suppress the rebels, but also the sinners of the people of Qin. Xiang Yu's despicable deeds undoubtedly pushed Liu Bang to the commanding heights and gave him a moral advantage that others did not have.
Liu Bang's strength was the only one among the princes of all walks of life who could confront Xiang Yu head-on. After that, the struggle for hegemony between Chu and Han fell into a situation of equal strength. Xiang Yu and Liu Bang's lobbyists persuaded Han Xin to deal with each other. Compared with xiang Yu's promise of vanity, Liu Bang not only agreed to Han Xin's request to seal the king's land, but he also made a vow to Han Xin that he would not add to Han Xin's iron weapon in his lifetime. In this way, Han Xin completely fell to the Han army, and under the two-way attack, Xiang Yu was finally defeated and died by the Wu River.
