Decolonising Archives presents the archive not as a neutral storehouse of cultural memory, but as a contested epistemic infrastructure through which power is organised, legitimised and resisted. The publication argues that coloniality survives beyond formal colonial rule through archival ownership, classification, access regimes, digitisation policies and market-driven extraction. Its central proposition is therefore double: archives must be protected from commodification as cultural capital, yet also radically rethought as sites where Western classificatory systems are exposed as instruments of imperial domination. The volume’s visual materials reinforce this argument: the cover image of Guinean women from unfinished revolutionary film footage, and the archival maps and visual-resistance materials reproduced in the Red Conceptualismos del Sur essay, show that archives are not inert remnants but unfinished political struggles. As a case study, RedCSur’s work with Latin American conceptualist and resistance archives demonstrates a decolonial practice grounded in preservation, collectivisation and activation rather than mere visibility; its Archives in Use platform seeks to return precarious artistic-political materials to public circulation without surrendering them to state violence or market neutralisation. Fraser and Todd’s essay on Indigenous research in Canada deepens the critique by insisting that decolonising state archives can only ever be partial, since such institutions remain bound to settler-colonial nation-making. Ultimately, the collection concludes that decolonial archival work is not simply a matter of digitising documents, but of transforming the conditions under which memory becomes knowledge, evidence, commons and political action.
