政治腐敗
Political corruption within the Manchu Qing dynasty had contributed to China's defeat in the war. Between 1847 and 1850 many Chinese leaders formed secret societies to overthrow the Qing. In 1850, under the leadership of Hong Xiuquan, the Taiping Rebellion broke out in Guangxi, and the movement would maintain control of large areas of southern China under the banner of the Taiping Heavenly Kingdom until its collapse in 1864.
