Much of the scholarship on Bangladesh’s founding places it within a narrative of repetition. It either repeats the partitions of 1905 or 1947 or the creation of India and Pakistan as postcolonial states. This paper argues instead for the novelty of Bangladesh’s creation against the postcolonial state, suggesting that it opened up a new history at the global level in which decolonisation was replaced by civil war as the founding narrative for new states.
