This chapter describes four online jihadist magazines: Al-Qaeda’s Inspire, ISIS’s Dabiq and Rumiyah, and Al-Shabaab’s Gaidi Mtaani. Although the publications of these periodicals have ceased, their popularity on the internet continues to influence would-be jihadists and youths. This chapter’s special focus, of course, remains on sub-Saharan Africa. The impact of these magazines is so widespread that anyone with no proclivity toward radicalism could metamorphose into a potential killing machine by reading those magazines.
