Centuries ago, as their forefathers faced social and economic deprivation, many low-caste Hindus embraced Christianity.
But in one corner of southern India, their hopes for equality remain unfulfilled hundreds of years on. Called "pariahs", hundreds of Dalit Christians continue to face discrimination - not from Hindus but fellow Christians.
More than 200km (124 miles) from Chennai, the capital of the southern state of Tamil Nadu, is the village of Eraiyur.
Home to about 3,000 Dalit Christians, mostly farm labourers and migrant workers, the area witnessed violence last year when Dalits demanded equal treatment.
The village is dominated by Vanniyar Christians numbering 15,000, who own most of the land and businesses.
They imposed restrictions on Dalits even though they had also converted to Christianity.
