FIFTY years ago, in the morning of December 25, 1968, the landlords of Keezhvenmani village in East Tanjore district, Tamil Nadu, unleashed one of the most violent attacks on dalits in independent India, killing 44 people including women and children.The attacks began as the landless dalits in the village started to agitate for wage hike under the banner of CPI(M), which was gaining ground in the state.
