Despite having the largest proportion of scheduled caste population in India, Punjab has rarely been seen as a relevant case for conceptualisation of the caste system and the changes taking place therein. Though some aspects of caste in Punjab have been studied, there has virtually been no detailed empirical documentation of the practice of untouchability in rural Punjab. Based on an extensive field-study, this paper provides a broad mapping of the prevailing caste relations and the practice of untouchability in rural Punjab. The study focuses specifically on the process of change, particularly in the context of agrarian transformations that the Punjab countryside has experienced in the wake of the success of green revolution technology. The paper also argues that the processes of change could be meaningfully captured through the categories of 'dissociation', 'distancing' and 'autonomy'.
