War is futile and should be avoided. Many creative writers have in their literary works, mirrored the devastating effects of war in societies with the aim to discourage the youths of the contemporary era of aspiring to engage in war of any sorts. This study examines the devastating impact of war-induced migration on family dynamics and relationships as mirrored by Adichie in Half of a Yellow Sun. The novel, with its setting as a Biafran land, during the civil war, vividly portrays the disintegration of traditional family norms, reconfiguration of relationships, and emotional struggles that accompany forced displacement. This research adopts Postcolonial theory as the most apt theoretical framework for the analysis of the experiences of the characters in the text. The research findings reveal that war does no one any good and that war-induced migration not only disrupts family structures but also challenges characters’ sense of self and belonging. This study is significant as it reveals the dangers of war and the consequent effects of war on individuals and society at large who participate in wars.
