This article offers reflection on how Gramscian theories can be useful for critically analyzing the political significance of the actions and resistances of urban subaltern Africans. It interrogates the potential of subaltern political forms to profoundly transform society and to thus prepare for the African “future city”. It merges a theoretical analysis of Gramsci's concepts relating to the città futura—and its relation to concepts of city, subalternity, political initiative and cittadinanza—with a comparative critique of urban theory applied to Africa and especially relating to the politicization of the city in Mauritania. Our reflections are based on Mauritania and the case of Nouakchott, its capital, where we have carried out our research for over a decade. We will interrogate the re‐appropriations or resistances, as well as the autonomous construction of modes of living and of city‐making, made by marginal inhabitants, in order to consider their political potentialities.
