In 256 BC, Liu Bang was born in Li Zhongyang, Fengyi (now Fengxian, Jiangsu), Qinzhipei County. In BC 10, Liu Bang rebelled and joined the peasant uprising army at the end of Qin Dynasty. In 207 BC, in 65438+ February, Liu Bangxian Xiang Yu stepped into the Qin Dynasty. In 206 BC, the story of Liu Bang sealing Hanwang and Hongmen Banquet happened. In 202 BC, Liu Bang destroyed Xiang Yu and successively conquered other insurgents to establish the Han Dynasty. From 20 1 year BC to 195 BC, it took Liu bang six years to destroy the king with a different surname. In BC 196, Lv Hou killed Han Xin. In BC 195, Liu Bang died at the age of 62 and was buried in Changling, Shaanxi. In 209 BC, a peasant uprising broke out at the end of Qin Dynasty. After Chen Sheng and the rebels captured Chen (now Huaiyang, Henan Province), Chen Sheng established the "Zhang Chu" regime and openly opposed Qin. At this time, Pei county magistrate also wanted to respond and continue to master Pei county regime. Xiao He and Cao Can were the main officials of the county magistrate at that time. They suggested that the county magistrate recall the people in exile in the county, which could increase their strength and prevent future troubles. Magistrate felt right, let Liu Bang's brother-in-law Fan Kuai get Liu Bang back, and Liu Bang took people back. The county magistrate here regretted it again, fearing that Liu Bang would return out of control or be killed by Liu Bang, which was tantamount to inviting wolves into the room. So, he ordered to close the gate, ready to capture Xiao He and Cao Can. When Xiao He and Cao Can heard the news, they quickly fled outside the city. Liu bang shot the letter into the city, encouraged the people in the city to rise up and kill the treacherous county magistrate, and together they defended their hometown. The people are very dissatisfied with the county magistrate who doesn't take care of them at ordinary times. After killing the county magistrate, they opened the gate to welcome Liu Bang and elected him Pei Gong to lead the uprising. Liu Bang listened to public opinion, set up an altar, called himself the son, and led the people to raise the anti-Qin banner. Liu Bang didn't go well at first, but after several battles, Liu Bang moved westward step by step, and finally arrived in Enemy at the Gates, Bashang (now Anton) not far east of Xianyang. Zi Ying, the king of Qin, saw that the tide was running out, so he had to surrender and give the imperial seal to Liu Bang, and the Qin Dynasty was thus destroyed. In the Chu-Han War, Liu Bang chased Xiang Yu in 202 BC 10, but by the time of Guling (now Taikang West, Henan Province), the troops of Han Xin and Peng Yue had not arrived. Xiang Yu made a fierce counterattack against the Han army and defeated it. Liu Bang had to insist, and immediately sent someone to promise Han Xin and Peng Yue, and immediately named them King Qi and King Liang after defeating Xiang Yu, so Han Xin and Peng Yue immediately sent troops. At the same time, Zhou Yin, the great Sima of Chu, was also sent by Liu Bang to surrender, and Ying Bu, the king of Huainan, led the troops to join forces. The Han army joined forces with various reinforcements of 300,000 to fight against Xiang Yu. At night, the desolate Chu songs came from the besieged Han army, which made Xiang Yu think that the Han army had occupied all the land of Chu. In desperation, Xiang Yu drank wine with his beloved concubine in the big tent and sang generously with the help of the wine: "If you pull out the mountain, you will be angry with the world, and if you are unfavorable, you will not die." What can I do without dying? "Yu Ji committed suicide with tears in front of Xiang Yu, who dried his tears and led 800 cavalry to break through overnight. After crossing the Huaihe River, there were only 100 people left, and they retreated eastward. In Dongcheng (now southeast of Dingyuan County, Anhui Province), Xiang Yu was overtaken by suckling cavalry, with only 28 people accompanying him. Xiang Yu fought the Han army three times, killed hundreds of Han troops, and finally committed suicide with a horizontal knife. On February 3, 202 BC, Liu Bang held a ceremony in Sishuiyang, Dingtao, Shandong Province, and named the country Han.
