Exogamy is a social rule or practice requiring individuals to marry outside their own social group, lineage, clan, or community. It is a key concept in anthropology and kinship studies, highlighting how societies regulate marriage to build alliances and prevent inbreeding.
🌍 Definition
- Exogamy: From Greek exo- (“outside”) + gamos (“marriage”), meaning “marriage outside.”
- It contrasts with endogamy, which requires marriage within a defined group.
🔑 Characteristics
- Kinship Regulation: Often prohibits marriage within close kin or clan.
- Alliance Building: Creates ties between different families, clans, or communities.
- Genetic Diversity: Reduces risk of inbreeding and increases genetic variation.
- Cultural Variation: Rules differ across societies—some enforce clan exogamy, others village or caste exogamy.
đź“š Examples
- Clan Exogamy: Among many Indigenous societies, individuals must marry outside their clan.
- Caste Exogamy: In South Asia, some groups prohibit marriage within the same caste subdivision.
