This is a reflection on the close relations of the writing of postcolonial histories and recent decolonial critiques, and on the tensions between them. Postcolonial historical analysis often has been preoccupied with hybridity and mixture, conjugation and adaptation, exchange and interaction—with subversions of sovereignty in contact zones, borderlands, and on the beach. As a structuralist formulation, decolonial historical binarism in contrast echoes Indigenous politics of self-determination, even suggesting at times an ontological decoupling of settler and Indigenous histories and practices. Stringent decolonization of historical inquiry—implying the sabotage and superseding of settler colonial linguistic, narrative, and temporal conventions and the disturbing of standardized assumptions about evidence, agency, and authorship—would give us an epistemic assemblage perhaps not recognizable as “history.” Even if desirable, is that imaginable now except as metaphor or ideal?
