Phratry

Phratry Definition

A phratry refers to a grouping or association of kinship groups (such as clans) that recognise some underlying relationship with one another, typically aggregating these smaller units according to principles other than direct descent. In many pre-industrial societies, social organisation was fundamentally based on kinship lines, but these lines were aggregated into larger structures through non-kinship criteria. These groupings often served functional purposes, being organised either around a division of labour or distinct ritual functions.

Historical Context and Terminology

The term ‘phratries’ was formally introduced by the anthropologist Lewis H. Morgan when describing such aggregations in various societies, including among American Indian and Australian Aboriginal tribes. While other extended kinship structures exist—such as the clan (often matrilineal) and the gens (patrilineal)—the concept of a phratry specifically denotes the association between these larger lineage groups.

Related Concepts

A specific manifestation of a phratry is the moiety system, which involves dividing an entire society into two distinct groups based on a shared principle, resulting in a dual organisation of the whole.

Academic Caution

It is important for students of kinship studies to recognise that terms related to social grouping are highly context-dependent. Consequently, users must exercise caution when employing terminology, as definitions and usages can vary significantly across different cultural circumstances.
