Ethnic groups in Chinese history

Ethnic groups in Chinese history refer to various or presumed ethnicities of significance to the history of China, gathered through the study of Classical Chinese literature, Chinese and non-Chinese literary sources and inscriptions, historical linguistics, and archaeological research.

Among the difficulties in the study of ethnic groups in China are the relatively long periods of time involved, together with the large volume of literary and historical records which have accompanied the history of China. Classical Chinese ethnography (like much premodern ethnography) was often sketchy, leaving it unclear as to whether Chinese-depicted names referred to a true ethnic group or a possibly multiethnic political entity. Even then, ethnonyms were sometimes assigned by geographic location or surrounding features, rather than by any features of the people themselves, and often carried little distinction of who the Han Chinese authors considered Chinese and non-Chinese for differences such as lifestyle, language, or governance. Many of the ethnonyms were historically used in such a way as to invite comparison with the word barbarian.^[1]
