There is a gap in knowledge when it comes to jihadism and how it is associated with notions of masculinity. Especially empirical studies on masculinity that are based on interviews with active or former jihadists are lacking. This study seeks to analyze the role that notions of masculinity have played in different phases of jihadiship among Swedish jihadist foreign fighters, from recruitment to traveling to the conflict zone, and then eventually returning to Sweden. With a focus on heroic jihadist hypermasculinity, which is a form of hegemonic masculinity that exaggerates male stereotypical behavior such as violence and aggression, the study identifies five themes: Recruitment strategies and masculinity; from masculine failure to protecting sisters in faith; jihad and street culture; the warrior ideal; jihad, patriarchy, and brotherhood; and returning home and preventing re-emasculation. The empirical material is based on interviews with six Swedish jihadists and a former jihadist recruiter.
