Xingshilu 姓氏錄

Xingshilu 姓氏錄 "Record of eminent families" is an official register of the most important families of the early Tang period 唐 (618-907). It was compiled on the imperial order of Emperor Gaozong 唐高宗 (r. 649-683) and Empress Wu Zetian 武則天 (r. 690-704). The reason for the compilation was that Gaozong deposed his empress Wang 王后 and installed Wu Zetian instead. To raise the position of the family Wu, the new empress had older family registers revised, such as the Zhenguan shizhu zhi 貞觀氏族志. In this revised family register, the family of Li Yifu 李義府 (614-666), the trusted Counsellor of the emperor, was also not mentioned.

The compilation of the Xingshilu was observed by Kong Zhiyue 孔志約 (fl. 659) and made by twelve people under the supervision of Yang Renqing 楊仁卿 (f. 659), Shi Yuandao 史元道 and Lü Cai 呂才 (606-665). The book was finished in 659, and the emperor personally wrote a preface.

The Xingshilu gives an overview of 245 families (xing 姓) and 287 households (jia 家), each of which is categorised in one of nine classes, according to the official ranks (see jiupin). All families producing officials of a rank higher than five were included in the Xingshilu. The members of the Wu family were all ranked in the highest class. The new official family register met resistance from military officials who saw themselves underrepresented. The newly compiled register had to be revised, and many older families whose power had vanished since were eliminated from the book.
