The essay introduces caste as a category for discussing the history of Partition of India, which until now has focused almost exclusively on the Hindus, Sikhs and the Muslims. The Dalit or the ‘untouchables’ of India are usually left out of this discussion, and whenever they are brought in, they are portrayed as either disinterested onlookers or accidental victims. On the contrary, as this essay will argue, the Dalit were deeply entangled in Partition politics, which threatened their natural habitat in eastern Bengal, where they had reclaimed land from marshes and forests, extended cultivation and set up human settlement. Their regional movement was gradually drawn into the broader subcontinental politics that led to Partition, and the movement as a result lost unity, autonomy and purpose. While one group of the Bengali Dalit leaders were opposed to Partition and believed that a Dalit–Muslim alliance was in the best interest of the Dalit, others got closer to Hindu nationalism and demanded Partition of Bengal. Many Dalit peasants were caught in this politics and became both victims and perpetrators of violence. The essay concludes that while the Dalit lacked power to influence the decision to partition, they nevertheless were forced to take positions within the political divide, which they did according to their own perceptions of caste interests and preferred political future of their physical space.
