Introduction to Wu Sangui
Wu Sangui is one of the most controversial figures in Chinese history. His actions and decisions had a profound impact on the transition from the Ming Dynasty to the Qing Dynasty. Born into a military - family, Wu Sangui showed great talent in military affairs from a young age.
He was initially a general of the Ming Dynasty, stationed at Shanhaiguan Pass, a strategic location that guarded the northern border of the Ming Empire. His military skills were highly regarded, and he was entrusted with important defense tasks.
Early Military Career
Wu Sangui's early military career was marked by numerous battles against the Manchu forces. He was known for his courage and strategic thinking in the face of the powerful Manchu army. His military achievements in the early stage helped to maintain the stability of the Ming Dynasty's northern border to some extent.
However, the internal situation of the Ming Dynasty was deteriorating. Corruption was rampant, and peasant uprisings were spreading across the country. These internal problems gradually weakened the Ming Dynasty's military and economic strength, putting Wu Sangui in a difficult position.
The Turning Point: Opening of Shanhaiguan Pass
The most significant event in Wu Sangui's life was his decision to open the Shanhaiguan Pass to the Manchu army. At that time, Li Zicheng's peasant army had captured Beijing, and the Ming Dynasty was on the verge of collapse. Wu Sangui was in a dilemma, facing the choice between surrendering to Li Zicheng's peasant army or allying with the Manchus.
There are different theories about his motivation. Some believe that it was because his concubine, Chen Yuanyuan, was captured by Li Zicheng's soldiers, which enraged him. Others think that he saw the weakness of the peasant army and hoped to use the Manchu forces to restore order and protect his own interests. In the end, he opened the pass, allowing the Manchu army to enter the Central Plains smoothly.
This decision had far - reaching consequences. It directly led to the fall of the Ming Dynasty and the establishment of the Qing Dynasty. Wu Sangui became a key figure in this historical transition, and his name was forever engraved in Chinese history.

Wu Sangui's Later Life and Historical Evaluation
After helping the Qing Dynasty to establish its rule in the Central Plains, Wu Sangui was granted a high - ranking title and large - scale fiefdoms. He became a powerful vassal king in the southwestern region of China.
Rebellion Against the Qing Dynasty
However, as time passed, Wu Sangui became dissatisfied with the Qing Dynasty's rule. He felt that the Qing court was gradually weakening his power. In 1673, he launched a rebellion known as the Revolt of the Three Feudatories, along with two other vassal kings.
The rebellion lasted for eight years. At the beginning, Wu Sangui's forces were quite powerful, and they occupied a large area in southern China. But in the end, due to various reasons such as internal strife among the rebels and the strong suppression of the Qing court, the rebellion was defeated. Wu Sangui died during the rebellion, and his family and followers were severely punished.
Historical Evaluation
Wu Sangui's historical evaluation is extremely complex. On one hand, he is often criticized for his betrayal of the Ming Dynasty. His opening of the Shanhaiguan Pass is seen as a major factor in the fall of the Ming Dynasty, and he is considered a traitor by many people in Chinese history.
On the other hand, some scholars also believe that his actions were a result of the complex historical environment at that time. The Ming Dynasty was already in decline, and he was in a difficult situation where he had to make a choice to protect his own interests and the lives of the people under his control. His later rebellion against the Qing Dynasty also shows that he was not completely satisfied with the Manchu rule and still had some sense of self - determination.
In conclusion, Wu Sangui is a multi - faceted historical figure. His life and actions reflect the complexity and changeability of Chinese history, and his story continues to be debated and analyzed by historians and the public.
