Subjective reasons: First, due to the limitations of the peasant class. Although the "Tian Chao Tian Mu System" was put forward, at that time, it was a fantasy and impossible to realize; The Taiping Heavenly Kingdom movement was vigorous, but China was still a feudal society.

the second is a strategic mistake. For example, after jintian uprising, he lingered around Bauhinia Mountain for a long time, lacking enterprising spirit; After the uprising, we did not do everything possible to win over intellectuals, and we could not unify anti-Confucius and winning over intellectuals; After its capital was Tianjing, it went north alone.

objective reason: joint strangulation by the Chinese and foreign coalition governments. This is a new situation that has never been encountered in any peasant war in the history of China. In 1861, Empress Dowager Cixi authorized Zeng Guofan to govern the military affairs of Jiangsu, Zhejiang, Anhui and Jiangxi provinces. In this way, the front line of the Qing army against the Taiping Army was all under the unified command of Zeng Guofan. Zeng Guofan sent Ceng Guoquan to lead the main force of Xiang, only for Tianjin; Li Hongzhang was sent to lead the Huai Army to attack Suzhou and Changzhou together with the "Chang Shengjun" commanded by the Englishman Gordon; Zuo Zongtang was sent to lead a part of the Xiang Army to attack Zhejiang. The Anglo-French aggressors helped Zuo Zongtang with mixed reactionary forces.

In addition, the laws and regulations of the Kingdom of Heaven are quite strict, and the criminal laws are cruel. Anyone who breaks the dogma will be sentenced to death, which violates the original revolutionary purpose of saving the world and humanitarianism.

In short, the Taiping Heavenly Kingdom Movement was a great peasant revolutionary war against feudalism and aggression, which was huge and magnificent in China's modern history. However, due to the limitation of class and times, the peasant class could not lead the China Revolution to victory.
