This chapter explores the role Jihadist narratives have played in the radicalization of young Muslims in the West towards violent extremism, and how these narratives have changed over the years as Islamic State (ISIS) has trumped Al-Qaeda in becoming the organization of choice for most Western Jihadists today. The chapter explores the biographies of numerous individuals drawn to violent extremism, including those who have travelled abroad as foreign fighters or conducted home grown domestic terrorist attacks. The study finds that radical narratives only have potency when they intersect with structural conditions or the lived experiences that individuals may find themselves in. The chapter explores the role of religion, identity, altruism, and socio-economic marginalization in helping to account for increasing recruitment to Jihadism, suggesting fruitful avenues for Countering Violent Extremism (CVE) measures.
