House of Li

The Li family were members of the northwest military aristocracy prevalent during the Sui dynasty.

During the late Northern and Southern dynasties period, the Li family intermarried with Xianbei royalty when Li Bing (the ethnically Han father of the first Tang emperor) married the part-Xianbei Duchess Dugu (the daughter of prominent Xianbei general Dugu Xin).

[6][7] Marriages between elite Han men and Xianbei princesses were common in this period, as the Northern Wei had arranged for Han elites to marry daughters of the Xianbei Tuoba imperial family since the 480s CE.

[18] In more recent times, some scholars have speculated that the Tang imperial family might have modified its genealogy to conceal Xianbei heritage.

[23] Descendants of the Tang Emperors now live in Chengcun village, near the Wuyi Mountains in Fujian.
