Xiang Yu entered the customs, Liu Bang withdrew from Xianyang, and Prince Ying of Qin surrendered. Xiang Yu proclaimed himself the overlord of Western Chu, set the capital of Pengcheng, and named Liu Bang as the king of Han, ruling the Bashu and Hanzhong regions. In the following four years, the struggle for hegemony between Chu and Han continued, and finally ended with Liu Bang's victory.
After Xiang Yu took over Xianyang, he took a series of measures to consolidate his rule. He first executed Prince Ying of Qin to show the complete destruction of the Qin Dynasty. Then, he began to rectify the ** of the Qin Dynasty, dividing them into different ranks and appointing or abolishing them respectively. He also ordered to gather the soldiers and ** from his hometown to Xianyang, reformulated his fiefdom and official system, and established his own dominance.
At the same time, Liu Bang was actively preparing for war in the Hanzhong region. He gradually expanded his sphere of influence through alliances with local powers. After learning that Xiang Yu had blocked the road to Guanzhong, he decided to use a roundabout tactic and attack Xiang Yu's army from the flank. He sent Han Xin as an envoy to Zhao and Yan to borrow troops, and at the same time united with other anti-Chu forces to form a powerful anti-Chu force.
After several years of conquest, both Chu and Han were exhausted. Xiang Yu's rule in Pengcheng was also gradually weakened by internal contradictions and external pressures. Liu Bang took the opportunity to launch a general attack on Xiang Yu. He led the Han army and the allied army to attack Xiang Yu's defense line from multiple directions, and finally defeated Xiang Yu in the Battle of Qixia.
When Xiang Yu retreated to Wujiang in defeat, there was no way out. He rejected his subordinates' suggestion to escape and chose to fight to the death with the Han army. In the end, Xiang Yu was killed by Liu Bang, and all his subordinates surrendered. After his victory, Liu Bang adopted a lenient policy towards Xiang Yu's subordinates, executing only a few of the most heinous criminals.
After the end of the struggle for hegemony between Chu and Han, Liu Bang summed up the experience of this war and pointed out: The victory or defeat of the war depends not only on the size of the military strength, but also on the support of the people and the strategic gains and losses. He believed that his greatest advantage in the war was the unanimous support of the people and supporters. At the same time, he also believed that his biggest mistake in the war was not sending Han Xin and others to attack Zhao and other regions in time, which led to his disadvantage for a while.
The war had a profound impact on Chinese history. It laid the foundation for Liu Bang to become the founding emperor of the Han Dynasty, and also left a wealth of experience and lessons for Chinese history. From today's point of view, this war still has a lot to learn from and Xi.
