Who uses Internet propaganda in civil wars and why?

Abstract This article explores who is likely to benefit from Internet propaganda in civil wars. It argues that the global reach of the Internet, its lack of regulation and its filtering tools are more likely to help transnational rebel groups with external support and radical aims than local groups with home-grown support and moderate aims. The paper then introduces a new dataset on rebel propaganda that includes every available piece of public, downloadable Internet communication produced by every major rebel group in the Iraqi civil war between January 2011 and December 2015. A preliminary analysis of group-level Internet communication during the war revealed a number of striking patterns. Internet propaganda was not equally used by all rebel groups in Iraq during this time period. Groups with potentially larger international backing and low levels of local support were much more likely to produce Internet propaganda than those with strong in-country support. Ideologically extreme groups were also more likely to generate a higher volume of Internet propaganda than other types of groups. Finally, rebel groups that were new to a war tended to rely more heavily on Internet propaganda than more well-established groups. The article concludes by discussing the potential implications this new media environment could have for civil wars moving forward.
