This investigation employs the analytical framework established by Braddock and Horgan to conduct a comprehensive content analysis of 79 official English-language propaganda videos disseminated by ISIS, with the objective of quantifying the thematic composition and the evolutionary trajectory of ISIS’s international media operations and propaganda machinery from 2014 to 2017. The findings reveal that a predominant portion of the videos articulate narratives extensively centred around themes of the adversary and religious discourse, with the Sharia (Islamic law) emerging as the most prevalent theme. This research concludes that at a global scale, the propaganda apparatus of ISIS has orchestrated an intricate narrative, incorporating adversarial, theological, and emotional elements, thereby delineating the advanced sophistication of ISIS’s global propaganda endeavours.
