Li Zicheng (1606 ~ 1645), formerly known as Hongji, was born in Mizhi, Shaanxi, and his family was from agriculture. He comes from a poor family, is a shepherd, has a little culture, and has been a servant in Yinchuan for a long time. During the reign of tomorrow and Chongzhen, there was drought and famine in northern Shaanxi for years, and farmers rioted in succession. In the third year of Chongzhen (1630), he was laid off as a postman and went to work in Zhangcunmeng Department without mud in Xichuan. Later, due to Zhang Cunxu's defeat, he became an army.

Shortly after the uprising developed and won, he became the king of Gao Yingxiang, pioneered the eighth detachment, and moved to Shaanxi, Jinnan, Yuchu and other places. 1July, 999, he was captured and sacrificed, inherited the name of King Chuang, and moved to southern Shaanxi and northeastern Sichuan. In February of 13th year, Zicheng Army retreated in Wuyushan, Fengjie, and once again lurked in Shangluo Mountain (now southeast of Shangzhou, Shaanxi).

In the same year, there was a severe famine and peasant riots in Henan. In mid-November, the rebel army passed through Shangzhou in southern Shaanxi to highlight Wuguan and moved to Henan, where farmers fought for it. Soon, Niu Jinxing, Song Xie and Yan Li, the scribes, voted one after another. At the beginning of 14th, he went to Luoyang, killed He Zhu, and opened a warehouse to help the poor, and his momentum expanded rapidly. Since then, Kaifeng has been besieged three times. The main force of the Ming army was destroyed, and the insurgents controlled the whole province of Henan, with nearly one million troops. Li Zicheng Uprising Army became the main force of peasant uprising army in the late Ming Dynasty.

Since the occupation of Luoyang, Li Zicheng has gradually transformed its past mobile operations into a military strategy of "one city, one side, and one divided army". In the first month of the sixteenth year, he successfully conquered the sky (now Zhongxiang, Hubei Province), played the banner of "restraining soldiers and comforting the people" and distributed leaflets of "no conscription for three years". He sought to move to Huangzhou, expose the tyranny of Zhu Ming, and publicize his operational purpose of cultivating benevolent teachers and saving people from fire and water. Over the past two years, it has swept through dozens of counties in five provinces of Henan, as well as Huguangjing and Xiangfu. /kloc-In February of 0/6, Xiangyang (now Xiangfan, Hubei Province) changed to Xiang Jing, and a new Shun government was established, with the self-styled Marshal Fengtian Chongyi and Luo Rucai as the general who helped the people on behalf of heaven. From Tongguan to Guide (now Shangqiu, Henan) in the west, to Runing (now Runan, Henan) in the east, to the Yellow River in the north, and to Songzi, Zhijiang and Lizhou (now Lixian, Hunan) in the south, there are more than 70 counties with local officials.

According to Jing Xiang, the rebels are looking for the capital. Li Zicheng adopted Gu Junen, a counselor, taking Shaanxi as the base first. /KLOC-In September of 0/6, the insurgents defeated Sun Chuanting in jia county, Henan Province, annihilated more than 40,000 Ming troops and seized hundreds of thousands of weapons. Since then, the insurgents have invaded Shaanxi in two ways. In the first month of the seventeenth year, Xi 'an was conquered and Ningxia, Lanzhou, Xining, Yongchang and Zhuanglang were captured.

After the rebels occupied Xi 'an, they officially named the country Dashun and changed it to Yongchang, taking the seventeenth year of Chongzhen as the first year of Yongchang. Change Xi to Chang 'an. Li Zicheng changed his name to Sheng and became king. In February of the same year, the insurgents attacked Beijing in two ways. The capital was besieged on March 18. Break into Beijing the next day. Ming Sizong hanged himself in Jingshan Park (now Jingshan). The Ming Dynasty perished.

After the occupation of Beijing, we will continue to divide our troops slightly, appoint local officials and establish grass-roots political power. The county magistrates of Beizhi, Shandong, Henan, Northern Jiangsu and Northern Anhui successively took office. At that time, the territory of Dashun started from Shandong in the east, Gansu and Ningxia in the west, along the Great Wall in the north and Jianghuai in the south, covering the northern branch, Shandong, Shanxi, Shaanxi and Henan provinces, part of Gansu, Qinghai and Ningxia in the northwest, several counties in Baoning area in northern Sichuan, and the Huaihe River basin in Jiangsu and Anhui today. There are four provinces of Jingzhou, Xiangyang, Chengtian and De 'an in the Yangtze River Basin in Huguang.

In the political and economic program of the uprising of the Rebel Army, in view of the concentration of land rights and heavy taxes in the Ming Dynasty, the slogan of "equal land system, free grain" was put forward. After Xi 'an was captured, it also demanded "even land" and "no levy for five years". In Henan and other places, the ballad of "not paying for food" is circulating everywhere. "Free grain for all fields" has not really been implemented, but some local officials have implemented measures to change feudal land rights. For example, in some areas, the local government in Dashun acquiesced in farmers' spontaneous land competition. The insurgents also implemented the policy of not having rich families to solve the military pay and help the poor. However, under this slogan, looting civilians and hurting innocent people also happen from time to time. The insurgents also implemented the policy of buying and selling flat and protecting industry and commerce. After the rebels entered Beijing, the citizens were allowed to open as usual. There are many merchant ships sailing on the Jifu Canal in Shandong Province.

After the failure of the uprising, when the rebels occupied Beijing, the only enemy in the north was Wu Sangui, the chief soldier of the Ming Dynasty stationed outside Shanhaiguan. I was lost in underestimating my enemy, so I only sent someone with gold and silver brocade to woo me. Sangui first took Zhao's house, and then Wen Zicheng sought reimbursement from a Ming official in Beijing. I heard that his family was detained. So he returned to Shanhaiguan to rebel and asked the Qing army for help. Liu Zongmin and Li Guo marched eastward and arrived at Shanhaiguan on April 21st. In order to prevent Sangui from retreating to the east, he created a 20,000-round raider to fight Sangguijun, and he led the army to attack from the west. Wu Sangui's army wavered, and the Qing army Dourgen sent his troops to attack. Being outnumbered and attacked on both sides, the peasant army lost to Beijing.

The failure of the peasant army caused panic in Beijing. Many generals of the rebel army can't stand the temptation of luxurious life in the city, and they are increasingly arrogant and extravagant, and their foot soldiers are also burdened with goods and have no fighting spirit. The army is distracted and the discipline is slack. On April 29th, the first year of Yongchang (1644), he hastily proclaimed himself emperor, left Beijing for the south the next day, and entered Shaanxi after Jin, trying to make a comeback based on Shaanxi. In May, he moved to counties in southeastern Hubei. From September to Jiugong Mountain (a cloud leads to the mountain and a cloud leads to the city), it was besieged by the landlord township group. After Li Zicheng's sacrifice, the rest was led south by Liu Zongmin and Lee Guo to unify the Ming and Qing Dynasties.
