This paper examines the representation of Osu slavery in Chinua Achebe’s No Longer at Ease. Whereas critics read the references to Osu as a minor subplot in the novel, this author suggests the dissipation of the Osu marriage plot illustrates the crisis of abolition within the context of anticolonial struggles. By situating Achebe’s novel alongside midcentury discourses on abolition, freedom, and marriage rights, the author argues that the novel’s form responds to the impasses between the abolitionist agendas of international law, the administrative mandate of colonial law, and indigenous Igbo agitations for and against the eradication of the Osu system. Key to this reading is the novel’s cursory reference to the 1956 bride price laws of eastern Nigeria. By narrativizing the failure of the 1956 legislation, Achebe reflects upon African implication in slavery as well as on the divergences between midcentury anticolonial internationalism and on-ground interpretations and improvisations of freedom.
