The practice of marriage within the boundaries of kin group, clan, lineage, village, and social class is known as endogamy. Endogamy refers to the social rule that encourages or requires individuals to marry within a specific group, maintaining cultural, social, or economic ties. This practice is often rooted in traditions and cultural norms that aim to preserve heritage, strengthen alliances, and ensure that social status and lineage remain intact within the specified group. Endogamy contrasts with exogamy, which is the practice of marrying outside one's social group or category. Understanding endogamy is essential in fields such as anthropology, sociology, and cultural studies as it highlights the intersections of social structure and marital practices.
