An Lushan (simplified Chinese: 安禄山; traditional Chinese: 安祿山; pinyin: Ān Lùshān, a transcription of the common Sogdian name Rokhshan meaning "the Bright") (ca. 703?– 29 January 757) was a general who rebelled against the Tang Dynasty in China. His name was also transcribed into Chinese as Āluòshān (阿犖山) or Gáluòshān (軋犖山), and he was posthumously named Prince La of Yan (燕剌王) by his deputy Shi Siming.
An Lushan was of Sogdian and Tujue origin, at least by adoption. He rose to prominence defending the northeastern border from the Khitan and other northern threats. He was summoned to Chang'an, the Tang capital, several times and managed to get the favor of Chancellor Li Linfu and Emperor Xuanzong. This allowed An Lushan to amass significant military power in northeast China. After the death of Li Linfu, his opposition with rival generals (Geshu Han) and Yang Guozhong created military tension within the Empire. The promotion of Yang Guozhong to Chancellor precipitated the catastrophic An Lushan Rebellion, which lasted from 755 to 763. Viewed as paranoid and dangerous, he was assassinated in 757 by his own son, An Qingxu, plunging his Yan dynasty into a turmoil that eventually led to its final collapse in 763.
