The Taiping Rebellion, one of the deadliest conflicts in history, primarily resulted in the weakening of the Qing Dynasty in China. Lasting from 1850 to 1864, it was a massive civil war led by Hong Xiuquan, who claimed to be the brother of Jesus Christ. The rebellion aimed to establish the Taiping Heavenly Kingdom, promoting radical socio-economic reforms and Christianity. Its violent suppression resulted in millions of deaths and contributed to widespread dissatisfaction with the Qing regime, eventually leading to modernization efforts and significant changes in Chinese society and governance.
