Religion is one of the many principles of social identification in India. It is becoming increasingly important – although, very often, what appears to be mobilisation on a religious basis can just as adequately, indeed more satisfactorily, be described in terms of caste, class or regional affiliations. Vested interests may encourage the reification of religions, and academics overseas, especially in Religious Studies departments, may, unwittingly, provide them support. This chapter examines the link between caste and religion, particularly in the case of the very lowest status groups. It suggests that both caste and religion mean very different things at different levels of the hierarchy. It then proceeds to look at the distinctive characteristics of religious identities in India. The discussion is related to wider debates about ethnic and racial identities and issues. Should class or interest group membership and allegiances be prioritised over other cultural identities, whether ascribed or acquired? It is argued that it is mistaken to reduce any one of these to another.
