Descent Groups — 2021 Paper I

Approach

• Demand of Question: Explain descent groups, their major forms and their role in social organisation.
• Structuring the Response: Define descent group → classify its forms → explain lineage, clan, phratry and moiety with functions.
• Key Dimensions to Cover: Unilineal/cognatic descent, lineage, clan, corporate character, Fortes, Radcliffe-Brown and ethnographic examples.

Model Answer

Introduction

A descent group is a socially recognised kin group whose members claim descent from a common ancestor according to culturally prescribed rules. A.R. Radcliffe-Brown viewed descent as an important basis of enduring social structure, while Meyer Fortes, through his studies of the Tallensi, demonstrated the corporate character of descent groups.

Major Principles of Descent

Unilineal descent: Membership is traced through one parental line.

• Patrilineal/Agnatic: descent through males.
• Matrilineal/Uterine: descent through females.

Double descent: Patrilineal and matrilineal principles operate simultaneously for different rights or purposes; the Yako of Nigeria are a classic example.

Cognatic descent: Connections may be traced through both male and female links. Bilateral and ambilineal arrangements fall broadly within cognatic reckoning.

Forms of Descent Groups

A lineage may be patrilineal or matrilineal and commonly acts as an exogamous and corporate unit. A clan is broader than a lineage and may also have totemic, territorial or ancestral identity.

Common Ancestor → Lineage → Clan → Phratry → Moiety

Functions of Descent Groups

Descent groups perform several interconnected functions:

• Social: define identity, membership and mutual obligations.
• Economic: regulate inheritance, property and access to resources.
• Political: provide leadership, solidarity and collective action.
• Ritual: organise ancestor worship, ceremonies and ritual responsibilities.
• Marital: often regulate exogamy and permissible marriage relations.
• Security: mobilise members during disputes and crises.

Among the Nuer, studied by E.E. Evans-Pritchard in The Nuer (1940), patrilineal descent groups also provided the basis for political organisation through segmentary lineages.

Conclusion

Descent groups transform genealogical connections into enduring social institutions. By organising property, marriage, ritual, political authority and collective responsibility, they become a fundamental principle of social organisation, particularly in kinship-based societies.
