Chinua Achebe’s Things Fall Apart (1958) can be credited as one of the first examples of postcolonial novel. It seems that the issue of Okonkwo’s suicide, which makes for the most climactic point of this novel, has got the attention of most critics as it has been studied for times. To be precise, the present article intends to approach this important issue in a new light with regard to the fact that it can be taken as a significant discursive sign in the narration system of the novel, standing for the revolutionary act the colonized would finally perform so as to express his revolt against the oppressive power of the colonizer and the colonial map shattering his precolonial identity and world. This article is then to speak about the idea that as a discursive sign, Okonkwo’s suicide has turned into a recurrent symbol in novels produced by the next generation of postcolonial novelists. To this end, Toni Morrison’s novel Beloved (1987), as a proof, is put into full analysis from the same perspective as Things Fall Apart in this study.
