Their founding father was Pei Ling (裴陵), the Lord of Jiepei (解𨛬君), who descended from the archaic Feng clan.
While being politically influential, the Pei family was also renowned for their scholarship in the study of Confucian classics.
17 men from the Pei clan served as chancellors in the Tang imperial government,[5] while there were numerous others who held lesser appointments.
The Pei family was never able to recover their political influence and ended up dissolving into different social classes.
[6] On the other hand, some epitaphs of the members of Pei family trace their origins to Pei Zhen, an exiled Qin noble who went to the Jin state and received a fief from Duke Ping, the Jin ruler.
