An Sishun

An Sishun (安思順) (died April 6, 756) was a general of the Chinese dynasty Tang Dynasty during the reign of Emperor Xuanzong, probably of Tujue (Göktürk) extraction. He was related to another general, An Lushan. After An Lushan rebelled against Emperor Xuanzong's rule in 755, another general who was inimical to An Sishun, Geshu Han, manufactured evidence that An Sishun was complicit in An Lushan's rebellion, and An Sishun was killed.

An Sishun's father's name might have been An Daomai (安道買), and appeared to be of Tujue extraction. An Daomai's brother An Yanyan (安延偃) had married a sorceress, Lady Ashide, who already had a son named Galuoshan, whom An Yanyan adopted and renamed An Lushan. At some point, An Yanyan's tribe suffered a catastrophe, and An Lushan, An Sishun, and possibly An Yanyan, fled to Tang Dynasty territory. At that time, another son of An Daomai's, An Zhenjie (安貞節), was serving as advisor to the Tang prefect of Lan Prefecture (嵐州, in modern Lüliang, Shanxi), and so they settled with An Zhenjie.

As of 747, An Sishun was serving as the military governor (jiedushi) of Shuofang Circuit (朔方, headquartered in modern Yinchuan, Ningxia), when, as a part of governor movements, Emperor Xuanzong made him the military governor of Hexi Circuit (河西, headquartered in modern Wuwei, Gansu), as well as acting governor of Wuwei Commandery. In 750, he assumed the military governship of Shuofang as well.

In 751, after Emperor Xuanzong met with and was impressed by the ethnically Goguryeo general Gao Xianzhi, who was then military governor of Anxi Circuit (安西, headquartered in modern Aksu Prefecture, Xinjiang), he issued an order making Gao the military governor at Hexi. However, An encouraged the non-Han chieftains under his command to cut off their ears and lacerate their faces and request that Emperor Xuanzong allow An to remain at Hexi, and Emperor Xuanzong did so.
