안록산의 난 (An Lushan Rebellion) was a major rebellion against the Tang Dynasty in China that occurred from 755 to 763 AD. It was led by An Lushan, a general of foreign origin, who seized the capital, Chang'an, and established a short-lived regime. The rebellion caused widespread destruction and loss of life, significantly weakening the Tang Dynasty. The conflict began due to political strife and dissatisfaction among military leaders and local populations. The Tang Dynasty struggled to regain control, leading to a prolonged civil war. Ultimately, the rebellion was suppressed, but it marked a turning point in Chinese history, contributing to the decline of the Tang Dynasty's power.
