Drawing on Tilly’s notion of “repertoire of action,” this article shows how the evolution of the global jihadist movement’s communicative action repertoire has increased the potential resonance of its discourse. It foresees the construction of the global jihadist movement’s discourse of mobilization as the result of the evolution of its network of actors, the context in which its communications are undertaken, and its adaptation to new communication technologies. Accordingly, it argues that the decentralization of the global jihadist movement has led to a widening of its communicative action repertoire and a diversification of its discourse offering.
