The discourse of caste, in many instances, cannot be constituted in separation from discourses on several other aspects of the Indian social structure. This paper, however, seeks to understand a relationship of a different order, that between caste and crime which in colonial India came to be linked in socially significant ways. Administrative discourse in colonial India sought to classify castes lower in the hierarchy and aboriginal tribes as criminal tribes and castes. Colonial administrative and metropolitan ideas and practices were thus used to classify certain groups as 'criminal'. Even as the state specified due requirements in the classification of such groups, these were prompted by broader imperatives - the consolidation of the colonial administrative edifice.
