About 150 years ago Lewis Henry Morgan compared relationship terminologies, societal forms and ideas of property to recognize the interdependence of the three domains. From a new perspective, the book re-examines, confirms and criticizes Morgan’s findings to conclude that reciprocal affinal relations determine most ‘classificatory’ terminologies and regulate many non-state societies, their property notions and their rituals. Apart from references to American and Australian features, such holistic socio-cultural constructs are exemplified by elaborate descriptions of little known contemporary Indigenous societies in Highland Middle India, altogether comprising many millions of members.
