Niu Sengru
Li Zongmin (李宗閔) (died 846?), courtesy name Sunzhi (損之), was a Chinese politician of the Tang Dynasty, serving twice as chancellor during the reign of Emperor Wenzong. He was considered one of the leading figures of the Niu-Li Factional Struggles — factional struggles between two factions at the Tang court that lasted decades — as a leader of the so-called Niu Faction, named after his colleague Niu Sengru.
