Holy War is a five-part series that lays out the ideologies and tactics behind the global Jihad movement, functioning as a primer for viewers with little background in the subject. Each episode focuses on a different piece of the puzzle, from the religious and political doctrines that jihadist groups invoke to the recruitment methods, propaganda, and operational tactics they use to spread influence and carry out attacks. The series relies on interviews, archival footage, and case studies to trace how these movements have grown and adapted over time, rather than treating jihadism as a single monolithic threat. It aims to give viewers the vocabulary and context needed to follow news coverage of terrorism and extremism with more understanding. The tone throughout stays analytical rather than polemical, presenting the material as a foundation for further study rather than a final verdict on any one group or region.
