Endogamy and exogamy represent contrasting approaches to marriage practices. Endogamy mandates marriage within a specific social group, such as a clan, tribe, or caste, aiming to preserve cultural or social cohesion and prevent the dilution of group identity. Conversely, exogamy requires individuals to marry outside of their own group, often to foster alliances with other groups or to avoid potential genetic issues arising from marrying close relatives. These practices reflect different social structures, values, and goals, shaping kinship networks and social dynamics in diverse societies around the world.
