Ли Цзычэн
Through the 1630s, rebellion spread from Shaanxi to nearby Huguang and Henan. In 1641, Xiangyang fell to Zhang Xianzhong, and Luoyang to Li Zicheng. The next year, Li Zicheng captured Kaifeng. The year after that, Zhang Xianzhong took Wuchang and established himself the ruler of his Xi kingdom. Court officials offered a number of unrealistic proposals to stop the rebel armies, including the establishment of archery contests, the restoration of the "weisuo" military colony system, and the execution of disloyal peasants. Li Zicheng took Xi'an in late 1643, renaming it Chang'an, which had been the city's name when it was the capital of the Tang dynasty. On the lunar New Year of 1644, he proclaimed himself king of the Shun dynasty and prepared to capture Beijing.
