Marking a century of debate, scholarship and politics, three texts by B R Ambedkar, M N Srinivas and Kancha Ilaiah, when read in intersection, present rich possibilities both for an understanding of caste and more importantly for a re-examination of the sociology/legal ethnography of caste and its genealogy. Ambedkar offered a multilayered, counter-hegemonic reading of caste that was lost on at least three generations of sociologists and possibly accounts for several of the conservative trends we have seen in the social sciences in institutions of higher learning. What is particularly interesting is the silence in the field of sociological work for at least five decades after Ambedkar's contribution to the sociology of caste.
