Bride service has traditionally been portrayed in the anthropological literature as the service rendered by the bridegroom to a bride's family as a bride price or part of one (see dowry). Bride service and bride wealth models frame anthropological discussions of kinship in many regions of the world. Rather than seeing affinity in terms of a "compensation" model whereby individuals are exchanged as objects, Dean’s (1995) research on Amazonian bride service among the Urarina demonstrates how differentially situated subjects negotiate the politics of marriage.
