exchange marriage, form of marriage involving an arranged and reciprocal exchange of spouses between two groups. Exchange marriage is most common in societies that have a unilineal descent system emphasizing the male line (patrilineality) and a consistent expectation of postmarital residence with or near the groom’s family (patrilocality). In such cases, the symmetry of an alliance is often maintained by a systematic exchange: whenever a marriage is arranged between a daughter from group A and a son from group B, a marriage between a daughter from group B and a son from group A is also arranged. Often, as among some Australian Aborigines and American Subarctic peoples, a traditional ideal was for a brother and sister from one family to marry a sister and brother, respectively, from another. When these processes are repeated by subsequent generations, the practice is known as cross-cousin marriage.

bridewealth, payment made by a groom or his kin to the kin of the bride in order to ratify a marriage. In such cultures, a marriage is not reckoned to have ended until the return of bridewealth has been acknowledged, signifying divorce.

The payment of bridewealth is most often a matter of social and symbolic as well as economic reciprocity, being part of a long series of exchanges between the two intermarrying families. It consolidates friendly relations between them, provides a material pledge that the woman and her children will be well treated, symbolizes her worth to the community, and provides a level of compensation to her natal family for the loss of her labour and company. Bridewealth is often one part of a reciprocal exchange, in which case it is accompanied by the provision of a dowry—a payment presented by the bride’s family to that of the groom.

Bridewealth may consist of money or goods, and it may be paid in one sum or in installments over a period of time. The goods transferred may include a diverse array of items such as livestock, bolts of cloth, drink, food, traditional weapons (such as spears), and vehicles. When the exchange entails the provision of labour to the bride’s family, it is known as bride service.

The practice is common in all parts of the globe in one form or another but, as an instrument for the legitimation of a marriage, is most highly developed in Africa. In many traditional African societies the husband could not assume full rights to the sexual, economic, or procreative powers of his wife until a standard portion of the bridewealth had been transferred.
