Ethnicity refers to a form of social identity based on shared cultural traditions, language, ancestry, history, customs, religion, and a sense of common origin. It is an important concept in the study of tribal society because tribal communities often define themselves through a distinct ethnic identity that differentiates them from other groups. Ethnicity is not determined solely by biological characteristics but is mainly based on cultural and social factors that are passed from one generation to another. Members of an ethnic group usually believe that they share a common heritage and maintain collective values, traditions, and practices that strengthen their unity. In anthropology and sociology, ethnicity is understood as both an objective and a subjective phenomenon. Objectively, ethnic groups may possess common language, dress, food habits, rituals, or geographical location. Subjectively, ethnicity depends on the feeling of belongingness and the recognition of a shared identity among members.
