Pugu Huai'en

Pugu Huai'en (僕固懷恩) (died September 27, 765), formally the Prince of Da'ning (大寧王), was a general of the Chinese dynasty Tang Dynasty, of Tiele ancestry. He was instrumental in the final suppression of the Anshi Rebellion, but rebelled against Emperor Daizong in fear that he was being accused of treason. After an initial defeat by other Tang generals, he led his own forces, allied with Uyghur Khaganate (pinyin: Huihe) and Tibetan Empire (pinyin: Tubo) forces, to attack the Tang capital Chang'an, but died on the way.

It is not known when Pugu Huai'en was born. His grandfather Pugu Gelanbayan (僕固歌濫拔延) was a chieftain of the Pugu tribe, one of the nine major constituent tribes of the Tiele Confederation who submitted to Tang Dynasty rule in 646, during the reign of Emperor Taizong. Emperor Taizong gave the nine chieftains titles as nine commandants, and Pugu Gelanbayan was made the commandant of Jinwei (金微). Pugu Huai'en's father Pugu Yilichuoba (僕固乙李啜拔) inherited the title as commandant of Jinwei, a post that Pugu Huai'en later inherited from him. During the Tianbao era (742-756) of Emperor Taizong's great-grandson Emperor Xuanzong, Pugu Huai'en was made a general and given the honorific title of Tejin (特進). He successively served under two military governors (jiedushi) of Shuofang Circuit (朔方, headquartered in modern Yinchuan, Ningxia), Wang Zhongsi and An Sishun, and both were impressed by his ferocity in battle and knowledge about the other non-Han tribes, as well as command skills, and so gave him great responsibility.
