In the present context, postcoloniality seems to disappear gradually for the benefit of globalised transculturality. The new mobilities of the black diaspora not only produce more diversity within the diaspora itself, but also new hybridities and intercultural connections. Thus, one may wonder about the evolution and the place of migrant and diasporic literatures in the future. I propose to show through a transversal approach how African American, Caribbean and African writers scattered throughout the Black Atlantic inscribe their works within a liminal “third space” that reflects an ontological hybridity. These writers build their own canons through a process of cultural and textual hybridisation, a negotiation of new codes that combine sameness with difference in an interactive way, initiating both a pluralistic decentering of writing and a new world order.
