In a March 2017 paper published by the International Centre for Counter-Terrorism—The Hague, this author introduced a framework for studying the construction of extremist identity through ideological texts. This Report will examine the framework against a historical example of the so-called Islamic State (IS) propaganda to illustrate how messaging strategies can be based on insights derived from the framework and the resulting analysis. This Report was presented at the 1st European Counter Terrorism Centre (ECTC) conference on online terrorist propaganda, 10-11 April 2017, at Europol Headquarters, The Hague.
