genatengsl
Genatengsl is a neologism used in speculative anthropology, sociology, and fictional world-building to describe a social system in which access to certain rights, obligations, and political authority is determined primarily by genealogical descent from a recognized ancestor or lineage. The term implies formal mechanisms for recording ancestry and validating membership in a lineage-based group. Core features typically include a genealogical register, explicit criteria for membership, ritual or legal recognition of lineage status, and governance structures that base leadership, inheritance, and resource allocation on lineal ties. In practice, genatengsl is most often discussed as a theoretical model or as a device in world-building rather than a widely observed real-world system.
Variants may be patrilineal, matrilineal, or bilateral; some formulations allow adoptive or collateral lines to gain
