As many as one million low-caste Hindus, known as Dalits or, less politely, “untouchables”, rallied in Mumbai to mark the 50th anniversary of the death of their leader, BR Ambedkar. Tensions were high after three Dalits were killed in rioting last week sparked by the vandalizing of a statue of Ambedkar, but the mass rally went off peacefully. It was the latest show of assertiveness by the long-marginalized group, whose efforts to gain international recognition Mother Jones covered a little while back.
