The increased visibility of same-sex relationships and the call for same-sex marriages have been particular challenges to the traditional marriage system in Africa in the contemporary period. While some critics have argued, erroneously, that same-sex relationships were completely unknown to the African continent until the advent of Western modernity, others have suggested that the practices speak to a greater malaise confronting African societies.

The article examines these developments around same-sex relationships in the context of wider social and economic challenges to the traditional marriage institution in Nigeria.
