The Taiping Rebellion was a massive civil war that was waged in China between the Manchu Qing dynasty and the Han, Hakka-led Taiping Heavenly Kingdom. It lasted from 1850 to 1864.
After fighting the bloodiest civil war in world history, with 20 to 30 million dead, the Qing government won decisively, although at a great price to its fiscal and political structure.
The uprising was commanded by Hong Xiuquan, an ethnic Hakka (a Han subgroup) and the self-proclaimed brother of Jesus Christ. Its goals were religious, nationalist, and political in nature and included the following:
*Hong Xiuquan sought the conversion of the Han people to a syncretic version of Christianity, Daoism, & Confucianism
*To overthrow the Manchu-led Qing Dynasty
*A state transformation--Rather than supplanting the ruling class, the Taipings sought to upend the moral and social order of China.
The Taipings established the Heavenly Kingdom as an oppositional state based in Tianjing (now Nanjing) and gained control of a significant part of southern China, eventually expanding to command a population base of nearly 30 million people.
