This paper investigates media framing and its impact on the postcolonial identity construction of Half of a Yellow Sun, a novel set in the Nigerian civil war of 1967 1970, by the author Chimamanda Ngozi Adichie, which prefigures conflicting narratives based on local propaganda, foreign journalism, and political discourse. Using the Media Framing Theory and Postcolonial Theory, this paper questions the ways in which information propagation, selective reporting, and ideological bias constitute divergent perceptions of Biafra, nationhood and identity. This study will claim that by revealing the politics of representation in the media discourse related to war time, Adichie reclaims narrative authority. The textual analysis of this paper shows that literature is a counter-frame to misconstrued media histories, thus re-creating postcolonial Nigerian identity internally.
