This article examines the upsurge in denunciations of ‘tribalism’ in public debate during The Gambia's transition from the autocracy of Yahya Jammeh to the ‘New Gambia’ under President Adama Barrow. In these public debates, derogatory statements about particular ethnicities articulate fears of present or future alliances to monopolise political power. These fears are disproportionate to attempts of organised political mobilisation on ethnic grounds, which remain marginal. It is argued that accusatory politics are a salient, and neglected, feature of ethnic dynamics in contemporary Gambian – and African – politics. This politics of accusation involves the contestation and negotiation of moral legitimacy in the political sphere, in a manner challenging the separation of the moral and the political undergirding scholarly distinctions between ethnicity and tribalism.
