Cultural affiliation is a research area that involves the identification and understanding of the cultural heritage and traditions of a particular group or community. This can include studying a group's language, customs, beliefs, and values, as well as their historical and social practices. Researchers in this area often work to establish connections between cultural groups and their material artifacts, such as archaeological sites, artworks, and objects. By studying cultural affiliation, researchers can gain insights into the ways in which communities express their identities and values through their cultural practices and artifacts. This research area is interdisciplinary and can involve fields such as anthropology, archaeology, sociology, and cultural studies.
