When Siraj, the ruler of Bengal, overran the British settlement of Calcutta in 1756, he allegedly jailed 146 European prisoners overnight in a cramped prison. Of the group, 123 died of suffocation. While this episode was never independently confirmed, the story of "the black hole of Calcutta" was widely circulated and seen by the British public as an atrocity committed by savage colonial Subjects. Partha Chatterjee's The Black Hole of Empire: History of a Global Practice of Power (Princeton, 2012) follows the ever-changing representations of this historical event and founding myth of the British Empire in India, from the eighteenth century to the present. Chatterjee explores how a supposed tragedy paved the ideological foundations for the “civilizing” force of British imperial rule and territorial control in India.
