The Tuoba founded the Northern Wei (386–535) around the Yellow River delta and increasingly sinicized. As a result, from 496, the name "Tuoba" disappeared by an edict of Emperor Xiaowen of Northern Wei, who adopted the Chinese language surname of Yuan (元) instead. A surviving branch of the Tuoba established the state of Tuyuhun before submitting as a vassal of the Tang dynasty; they later established the later Western Xia, whose rulers adopted the Chinese surname Li (李).
The distribution of the Xianbei people ranged from present day Northeast China to Mongolia, and the Tuoba were one of the largest clans among the western Xianbei, ranging from present day Shanxi province and westward and northwestward. They established the state of Dai from 310-376 CE and ruled as the Northern Wei from 386-536. The Tuoba states of Dai and Northern Wei also claimed to possess the quality of earth in the Chinese Wu Xing theory. All the chieftains of the Tuoba were revered as emperors in the Book of Wei and the History of the Northern Dynasties. Most scholars agree that the Tuoba were proto-Mongols or belonged to their own branch of Ural-Altaic language family, although some also suggest that instead of being related to the Mongols, they were perhaps related to the Turkic peoples. The Rourans considered that Tuoba and Rourans descended from common ancestors.  Also a historian of the Northern Wei noted that Rourans descended from Xianbei.
The Northern Wei started to arrange for Han Chinese elites to marry daughters of the Xianbei Tuoba royal family in the 480s. Some Han Chinese exiled royalty fled from southern China and defected to the Xianbei. Several daughters of the Xianbei Tuoba Emperor Xiaowen of Northern Wei were married to Han Chinese elites, like Princess Lanling 蘭陵公主 to Liu Hui 刘辉, who was a descendant of Liu Song royalty who fled north to the Xianbei in exile, Princess Huayang 華陽公主 to Sima Fei 司馬朏, a descendant of Jin dynasty (265–420) royalty, Princess Jinan 濟南公主 to Lu Daoqian 盧道虔, Princess Nanyang 南阳长公主 to Xiao Baoyin 萧宝夤, a member of Southern Qi royalty.
