This study examines the representation of mourning as a form of political resistance in Dust by Yvonne Adhiambo Owuor. Moving beyond the conventional perception of grief as a private emotional experience, the novel reconfigures mourning as a collective, historical, and political act deeply embedded in Kenya’s postcolonial realities. Situating Dust within Kenya’s post-independence history, it argues that mourning transcends private sorrow to become a collective and subversive act that challenges state-sanctioned silence and historical erasure. Through fragmented narratives, silenced histories, and embodied trauma, Dust exposes how national grief emerges from unresolved violence, state betrayal, and suppressed memory. The methodology is based on qualitative textual analysis, employing close reading of narrative structure, characterization, and symbolism, while drawing on postcolonial theory, trauma studies, and memory studies to interpret the text within its socio-political context. The result reveals that the novel configures that mourning functions as both a critique of state power and a means of reclaiming agency. Moreover, it presents grief as collective and subversive force that disrupts official national narratives, recovers marginalized histories, and exposes unresolved trauma. Ultimately, mourning emerges not as a passive suffering but as an active practice that resists erasure and calls for historical accountability of national healing. The analysis draws on postcolonial theory and trauma studies to demonstrate that mourning in the novel functions as both a critique of state power and a means of reclaiming agency. It is a language through which marginalized voices reclaim suppressed histories. Moreover, findings reveal that mourning is similar to grief which becomes a powerful tool through which marginalized voices challenge official narratives and reconstruct alternative histories. Ultimately, Dust portrays mourning not as passive suffering, but as an active and necessary resistance against political amnesia and systemic injustice.
