The Morichjhapi clearance of refugee settlers
In 1978–79, thousands of low-caste Hindu refugees from East Pakistan/Bangladesh left government camps in central India and settled Morichjhapi, a Sundarbans island, clearing land and building a self-organised community. The West Bengal government declared the settlement illegal under forest-protection law, blockaded the island to cut off food and water, and forcibly evicted the settlers with many deaths. Through the schoolteacher Nirmal's notebook and the settler Kusum, the novel presents this as a state choosing a tiger habitat over destitute people.
