Li Xiucheng (Chinese: 李秀成; pinyin: Lǐ Xiùchéng; 1823 – August 7, 1864) was a military commander during the Taiping Rebellion. Born to a peasant family, he was known as the Loyal King (忠王) by the end of his life. This title was bestowed after he refused a bribe from a Qing general officer to kill Hong Xiuquan, the founder and leader of the rebellion. As a general, he led Taiping forces to several victories. After his capture and interrogation at the third and final Battle in Nanjing in 1864, he was executed by Zeng Guofan. By the end of the rebellion, Li was the most important military leader of the rebel forces.
