Did you know?
Marriage outside of a specific group especially as required by custom or law is exogamy. Exogamous groups sometimes even specify the group into which members must marry. Such groups are usually defined in terms of kinship rather than in terms of politics or territory. Exogamy is usually characteristic of groups that trace descent through either the maternal or paternal line only.
