This thesis investigates how the African diasporic literary platforms AFREADA, Midnight & Indigo and Isele Magazine foster decolonial imaginaries while simultaneously operating within global capitalist systems. Through an analysis of three short stories published on these platforms, this thesis employs a calibrated methodology that bridges literary sociology and close reading, drawing on Afropolitan theory, Black critical studies and decolonial feminism. This study underscores how these platforms construct Afropolitan and feminist subjectivities and negotiate market demands, particularly through community-building and bibliotherapy. By highlighting the contradictions between the social logics that drive the platforms and the literary specificities of the narratives they enable, this research demonstrates that these texts refuse legibility, reconciliation, and bibliotherapeutic closure, instead exemplifying aesthetic fugitivity and portraying gendered and racialised characters that exist within and beyond dominant frameworks. This thesis advances current scholarly conversations on the decolonisation of English literary studies, highlighting the decolonial potential of African diasporic platform-based literary production.
