This is Hong Xiuquan, the extremist Christian who orchestrated the biggest and most bloody civil war in history, the Taiping rebellion. It happened around the same time as the American civil war, and shared a lot of similarities.
The Taiping’s had some previously unimaginable beliefs in China, like equality for men and women (women fought in their army, which reached a million people) and no private ownership of land.
From the Encyclopaedia Britannica:
Taiping Christianity placed little emphasis on New Testament ideas of kindness, forgiveness, and redemption. Rather, it emphasized the wrathful Old Testament God who demanded worship and obedience. Prostitution, foot-binding, and slavery were prohibited, as well as opium smoking, adultery, gambling, and use of tobacco and alcohol. Organization of the army was elaborate, with strict rules governing soldiers in camp and on the march. For those who followed these rules, an ultimate reward was promised. Zeng Guofan was astonished when, after the capture of Nanjing, almost 100,000 of the Taiping followers preferred death to capture.https://www.britannica.com/event/Taiping-Rebellion
Under the Taipings, the Chinese language was simplified, and equality between men and women was decreed. All property was to be held in common, and equal distribution of the land according to a primitive form of communism was planned. Some Western-educated Taiping leaders even proposed the development of industry and the building of a Taiping democracy. The Qing dynasty was so weakened by the rebellion that it never again was able to establish an effective hold over the country. Both the Chinese communists and the Chinese Nationalists trace their origin to the Taipings.https://www.britannica.com/event/Taiping-Rebellion
We believe these historical events contributed directly to the creation of Taijiquan. Without the Ching court being rocked to its core respected Confucian court officials like Wu Yuxiang and his brother would not have even interacted with a low-level martial artist like Yang Luchan. But the Taiping rebellion was not the only crises happening in China at the same time. A dynasty can survive one crisis, but several at once? No chance. The Yangtze river flooded leading to a catastrophic famine and loss of life and the British and the French started the second Opium war. There was also the Nian rebellion in the North.
The Taiping’s were eventually defeated with help from the Mongols and British. (The British wanted to sell opium, to sustain their empire and the Taiping’s were against that). If the rebellion had suceeded, just imagine the different China that would have emerged.
