This chapter explores sociological and anthropological approaches to the study of human rights. Anthropologists and sociologists have typically been either positivists or relativists. Consequently they have been slow to develop an analysis of justice and rights, thus lagging behind other disciplines in analysing the growth of universal human rights. This chapter shows how sociology and anthropology finally engaged with the concept of universal human rights after a long disciplinary focus on cultural relativism and legal positivism. It considers how sociology expanded its analysis of citizenship rights to that of human rights and how anthropology turned its ethnographic methodology towards an examination of the ‘social life of rights’. It also describes ‘social constructionism’ as a common bond between sociology and anthropology, laying emphasis on the importance of sociological and anthropological perspectives to the study of human rights.
