This article explores the links between autochthony discourses and physical violence through a case study of a Mai-Mai group in the eastern DR Congo. While this group garners support by employing such discourses and related tropes of autodéfense (self-defense), there are clear limits to the capacity of these narratives to mobilize for and legitimize violent action. Furthermore, much of the violence committed by the Mai-Mai is not informed directly by notions of autochthony, but is rather geared toward the consolidation of power. This observation should act as a caution against the a priori coding of violence according to the ways it is discursively framed by its protagonists.
