Cui Yin

Cui Yin (崔胤) (854-February 1, 904), courtesy name Chuixiu (垂休), nickname Zilang (緇郎), formally the Duke of Wei (魏公), was an official of the Chinese dynasty Tang Dynasty, serving as a chancellor during the reign of Emperor Zhaozong. He was one of the controversial figures in the late Tang period, who ruthlessly tried to destroy the powerful eunuchs at court and whose actions in that regard had traditionally made him regarded as one of the persons causing the demise of the dynasty at the hands of the warlord Zhu Quanzhong the military governor of Xuanwu Circuit (宣武, headquartered in modern Kaifeng, Henan) (who would overthrow Tang and establish his own Later Liang).

Cui Yin was born in 854, during the reign of Emperor Xuānzong. He was from the prominent Cui clan of Qinghe (清河, in modern Xingtai, Hebei), which claimed ancestry from the ruling house of the Spring and Autumn period state Qi, and which traced its ancestry to officials of Qin Dynasty, Han Dynasty, Cao Wei, Jin Dynasty (265-420), Later Zhao, Southern Yan, Liu Song, Northern Wei, Northern Qi, and Tang Dynasty. Cui Yin's father Cui Shenyou was a chancellor during Emperor Xuānzong's reign. Cui Yin had at least one older brother, Cui Changxia (崔昌遐). (According to the biography of the powerful eunuch Qiu Shiliang in the New Book of Tang, Cui Yin developed a hatred for eunuchs early in his life due to Cui Shenyou's relating to him of an incident during the earlier reign of Emperor Xuānzong's nephew Emperor Wenzong, when Qiu tried to have Emperor Wenzong deposed.)
