Walter Mignolo's gnosis fronteriza and María Lugones's coloniality of gender reveal how epistemic violence operates through categories imposed from outside—the mapping of territories, the classification of peoples, the universalisation of Western knowledge as the only valid form. Topolexical sovereignty emerges as response to this violence: not refusal of relation but insistence on situated terms, the right to name one's own world from within one's own epistemic location. This struggle resonates across domains. Infrastructure Studies reveals how colonial pipelines, ports and railways continue to structure territory long after formal decolonisation, materialising epistemic violence in concrete and steel. Science and Technology Studies traces the Western assumptions embedded in scientific protocols, showing how standards carry epistemological bias. Media Archaeology excavates the technical media through which colonial categories were imposed—maps, censuses, archives—and the forgotten alternatives they suppressed.
