"Caste, as we know it today, is not in fact some unchanged survival of ancient India, not some single system that reflects a core civilizational value, not a basic expression of Indian tradition. Rather, I will argue that caste (again, as we know it today) is a modern phenomenon, that it is, specifically, the product of an historical encounter between India and Western colonial rule. By this I do not mean to imply that it was simply invented by the too clever British, now credited with so many imperial patents that what began as colonial critique has turned into another form of imperial adulation. But I am suggesting that it was under the British that “caste” became a single term capable of expressing, organizing, and above all “systematizing” India’s diverse forms of social identity, community, and organization. This was achieved through an identifiable (if contested) ideological canon as the result of a concrete encounter with colonial modernity during two hundred years of British domination. In short, colonialism made caste what it is today."
