The Taiping Rebellion in China was a massive civil war led by Hong Xiuquan, who claimed to be the younger brother of Jesus Christ. It resulted in the deaths of millions and widespread destruction. The rebellion challenged the ruling Qing dynasty and called for radical social and political reforms, including the establishment of a Taiping Heavenly Kingdom. Though ultimately suppressed, the rebellion weakened the Qing dynasty, hastening its decline and paving the way for the modernization and revolution in China. Its legacy is seen in ongoing debates over governance, social justice, and the role of religion in Chinese society.
