Which dynasty was the dispute between Chu and Han?
The first year of Han dynasty
Historical background
In the thirty-seventh year of Qin Shihuang (2 10 BC), Qin Shihuang died in a sand dune (now northwest of Guangzong, Hebei Province). The CRRC government ordered Zhao Gao and others to launch a coup in the sand dunes, and Jiao Zhao executed his eldest son Fu Su and general Meng Tian, and made his youngest son Hu Hai the second emperor. Qin Ershi is fatuous and dissolute, and Zhao Gao is authoritarian and disorderly. The world is getting more and more tired and the people are miserable. The empire went from bad to worse, and ten years of tyranny finally triggered the peasant uprising at the end of Qin Dynasty.
In July of the first year of Qin Ershi (209 BC), Chen Sheng and Guangwu first launched an uprising in osawa Township and established the "Zhang Chu" regime. Chen Sheng claimed to be the King of Chu, and at that time the whole world responded in succession. In September, after Xiang Yan, the former general of Chu, Xiang Liang and an uncle of Xiang Yu launched the Huiji uprising, and Xiang Liang became Wu Xinjun. In the same month, Liu Bang, the former director of Sishui Pavilion, also responded in Pei County (now Pei County, Jiangsu Province), which was called Pei Gong in history.
After the failure of Chen Sheng and the peasant uprising, in February of the second year (208 BC), Xiang Liang called the leaders of various rebel forces in Chu to discuss in Xue County (now Tengzhou, Shandong Province), and Liu Bang also led his troops to join Xiang Liang. At that time, Yan, Zhao, Qi and Wei were all kings, and Xiang Liang adopted Fan Zeng's suggestion and made his grandson king, which is now known as "Chu Huaiwang". In August, Zhang Han, the supreme commander, launched a battle with Xiang Liang after attacking and killing Wang Wei, the leader of the anti-Qin armed forces, and Tian Yun, the king of Qi. Xiang Liang died of underestimating his enemy, so he thought that Chu was no longer worried, so he led his troops north to attack Zhao, and surrounded the prince of Zhao in Julu (now southwest of Pingxiang, Hebei). The prince of Zhao turned to the princes for help (Historical Records of the Emperor Gaozu).
Zhang Han's attack on Liang Jun shocked Chu. Liu Xiang gave up Liu Chen and led the army eastward. In October of the third year of Qin Ershi (208 BC), Chu Huaiwang moved the capital to Pengcheng (now Xuzhou, Jiangsu); And Xiang Chen Jun will take his father Lu Qing as the pillar of the country, seal Pei Gong Liu Bang as the Hou of Wu 'an, serve as the county magistrate, and command the soldiers of counties; Xiang Yu was named Hou of Chang 'an and Duke Lu.
Then, Chu divided his troops into two roads, all the way north to save Zhao and all the way west to attack Qin. I thought that I was a general, with "Qing Zi's top scholar" as the title, Xiang Yu as the second general, and Fan Zeng as the last general who went north to save Zhao; Liu Bangze withdrew from Xiang Liang and Chen Sheng, and based on this, he made a western expedition to the State of Qin. Chu Huaiwang agreed with the generals: "The one who enters the customs first is king."
Before the Western Expedition, Liu Bang went north to recruit Chen Chu skirmishers, and successively captured some areas around Luoyang in an attempt to seize Luoyang, and entered the customs through Tongguan. Later, Luoyang county soldiers went out of the city to meet the defeat and fled south. With the support of local strongmen represented by Li Shiqi, they changed their strategy and turned to Wuguan Road to enter the customs. After several months of fighting, they entered the suburbs of Xianyang in the first year of Han Dynasty (207 BC), defeated Qin Jun in Lantian, and Zi Ying, king of Qin, defected to Liu Bang. The Qin Dynasty perished. When Liu Bang entered Xianyang, he had an appointment with his elders in Guanzhong.
In December of the third year (208 BC), Xiang Yu killed the champion, seized his military power, led an army to the north to save Zhao, broke the king from the main force of the northern border army in the Battle of Julu, and then broke it. Finally, the general of Qin surrendered. Xiang Yu is a "vassal general" who led the vassal army into the customs. Meeting Liu Bang at Hongmen is the famous banquet in history.
After the hongmen banquet, xiang yu went to slaughter xianyang, killed the imperial clan of qin dynasty, burned Qin Gong and plundered guanzhong.
