Huang Chao was a Chinese rebel, best known for leading a major rebellion that severely weakened the Tang dynasty.

Emperor Xizong of Tang, né Li Yan, later name changed to Li Xuan, was an emperor of China's Tang dynasty. He reigned from 873 to 888. He was the fifth son of his predecessor Emperor Yizong and was the elder brother of his successor Emperor Zhaozong. His reign saw his realm overrun by the great agrarian rebellions led by Wang Xianzhi and Huang Chao, and while both were eventually defeated, by the end of Emperor Xizong's reign, the Tang state had virtually disintegrated into pieces ruled by individual warlords, rather than the imperial government, and would never recover, falling eventually in 907.
