Southern Ming
In the seventeenth year of Chongzhen (崇祯, 1644), Li Zicheng (李自成)'s rebellious army captured Beijing, and Zhu Youjian (朱由检),Emperor Chongzhen, hanged himself in Meishan. When the Qing army entered the Central Plains (中原地区), most of the imperial families and ministers of the Ming Dynasty fled to the south. They had half of the rivers and mountains south of the Huaihe River to resist the Qing army, including the Hongguang (弘光) regime, the Lu Kingdom (鲁王), the Longwu (隆武) regime, the Shaowu (绍武) regime, the Yongli (永历) regime and the Ming Zheng (明郑) regimes.
