In the seventh year of the Apocalypse (1627), Wang Er led the hungry people into the county seat and killed Zhang Douyao, which opened the prelude to the peasant uprising in the late Ming Dynasty. In the eighth year of the Apocalypse (1628), Wang Daliang and Ansai in Fugu, Shaanxi Province led a famine uprising, Zhang also rebelled in Mizhi and Yan 'an, and Li Zicheng later joined the army. The most influential people in this period were the rebels in Wang Jiayin. However, the peasant uprising army did not have a unified command, and its composition was complex, lacking a clear goal of overthrowing the Ming regime.
After Wang Jiayin's sacrifice, he, Zhang, Luo Rucai and others collectively called the 36th Battalion, and continued to fight in Jin, and the peasant uprising army entered the stage of coordinated operations from a decentralized state. The king takes himself as the leader.
After Wang's personal sacrifice, he became a leader. After the sacrifice, the insurgents gradually formed two powerful forces, one headed by Zhang, active in Hubei, Anhui and Henan; The other, headed by Li Zicheng, is active in Gansu, Ningxia, Shaanxi and other places. Later Li Zicheng overthrew the Ming Dynasty.
