Ningyuan's victory was part of the Ming and Qing wars. The victory in Ningyuan was not a big battle, but it had a great influence on the Ming Dynasty. Because in terms of the number of deaths, this is not a big battle, but it is a very important battle in terms of its impact on national affairs. The victory of Ningyuan was a battle between the Ming Dynasty and the later Jin Dynasty in the first month of the sixth year of the Apocalypse (1626). After the Ming army won, the Jin army was defeated. This is the first time that the Ming army was defeated by the Jin army. In the battle of Ningyuan, the Ming army won in Ningyuan City, the main battlefield, and lost in Juehua Island, the auxiliary battlefield, but generally speaking, victory was the mainstay, so the Ming Dynasty called this victory "a great victory in Ningyuan". After the victory of the battle of Ningyuan, Jin lost 1.7 million troops.

The battle of Ningyuan took place in the sixth year of the last two emperors of the Ming Dynasty. At that time, the post-Jin (later called Manchu) forces rose in Liaodong, unified the Jurchen nationality and began to attack the Ming Dynasty. They successively won the battles of Fushun, Qingshuibao, Liaoshen and Guangning, and sang a triumphant song all the way. The Ming Dynasty sent Sun Chengzong, the teacher of the Apocalypse Emperor, to supervise Ji Liao, which was also quite effective, so that the latter Jin did not dare to do it again. However, Sun Chengzong was attacked by court eunuchs and was dismissed. Sun Chengzong was replaced by Wei Zhongxian's confidant Gaudi.

The war of Ming and Qing Dynasties was a cruel war of changing dynasties, so the situation was extremely fierce in this war. However, the Ming army occupied the home court advantage, was very brave on the battlefield, and the situation was very clear. Only more than 200 people were lost, which is not only the reason for home advantage, but also the level gap between war weapons and soldiers, gradually showing the differences between countries.

The history of the Ming dynasty is very complicated, especially in the late Ming dynasty, when the party struggle in the imperial court was fierce, and the border war seemed to be inextricably linked with national politics. Under the command of Yuan Chonghuan, the historical background of the Ming army's first victory over the latter Jin army in Ningyuan was exactly the same.
