Abstract Tamil Nadu’s language policies are of particular interest to language policy researchers because, to a large extent, it was Tamil Nadu’s strong opposition that made the Indian government abandon its initial plan to adopt Hindi as the only official language of India. Due to a (scientifically unproven) Aryan invasion theory propagated by Christian missionaries in the nineteenth century, Hindi was associated with ‘Aryans’ who ‘invaded and subjugated’ the indigenous people of India (Dravidians, including Tamils). Moreover, Hindi was associated with Brahmins, the dominant caste in Hindu society. As a result of the intertwining of language with race and caste, Tamil Nadu’s language policy has been shaped by binaries of ‘Aryan vs. Dravidian’, ‘Hindi vs Tamil’, ‘North vs. South’, ‘Brahmins vs. Non-Brahmins’ and strongly focused on the promotion of Tamil, the official language of the state. However, Tamil Nadu is also home to 17 minority languages. This chapter examines legislation concerning the use of minority languages and finds that macro-level power has largely remained focused on promoting Tamil, but makes room for the use of languages other than Tamil in the domain of social welfare.KeywordsTamil NaduLanguage policiesRaceCasteBinaryAryanDravidian
