This article examines the politics of restitution within the Black Atlantic through the case of the Restitution Study Group’s legal challenge to the Smithsonian Institution’s return of Benin bronzes to Nigeria. While most scholarship frames restitution as a struggle between Western museums and postcolonial states, this article shifts the lens to intra-Black debates that complicate inherited frameworks of return, foregrounding the unresolved legacies of slavery and the claims of Black American and broader diasporic communities. At the same time, it situates these debates within the larger global landscape in which Western institutions and nation-states continue to define the terms and tempo of restitution. By challenging the assumption that restitution is solely a matter between source nations and former colonial powers, the Restitution Study Group brings attention to how African elites’ historical participation in the transatlantic slave trade and the ongoing marginalization of diaspora communities shape contemporary claims. The article also places these interventions alongside disputes within Nigeria over custodianship between the federal government, Edo State, and the Benin royal court. By tracing these overlapping histories, ethical claims, and political stakes, the article argues that returns of looted artifacts are not simply acts of restitution, but processes of decolonial repair that reconfigure authority, belonging, and historical responsibility across diasporic and national contexts.
