Cause of failure

Premature establishment loses motivation. After the Taiping Army conquered Nanjing, Yang led civil and military officials to welcome Hong Xiuquan into the city. So I decided to build Nanjing as the capital and change Nanjing into Tianjing. When the Taiping Army captured Wuchang, there was a question of where to go. Entering Henan in the north threatens the Qing dynasty, and entering Jinling in the east is likely to form a separatist situation. Now that the Taiping Army has successfully captured Nanjing, there is still a question of where to go.

The peasant class has its inherent limitations. The Taiping Heavenly Kingdom bears the brand of the old peasant war. The dispersion, conservatism and shortsightedness of the peasant class are outstanding in the Taiping Army. Many Taiping soldiers took part in the revolution out of necessity, hoping to change the poor and backward economic situation.

Because of this, even the most brilliant peasant leaders in history can only act according to the track of feudal countries. Hong Xiuquan originally wanted to establish a new dynasty and a new country, but when Yong 'an was crowned king, he couldn't even find a suitable name, so he had to "make an example from the mortal world" and named all the departments such as Zuo Fu, Youbi and Lingshou as princes, and accordingly formulated the Taiping ceremony system, stipulating the pecking and privileges of officials at all levels.

Hong Xiuquan also publicly preached the three cardinal guides and five permanents in feudal morality in Poems of the Heavenly Father, saying that "only the daughter-in-law has no fault, and only the minister has no fault". Due to the limitations of history and class, once the form of political power goes along the track of feudal political power, its nature changes and the leaders' thoughts change, and they lose their support for the revolutionary cause.
