Almost a decade ago, the Sunni jihadist network known as the Islamic State (IS) declared the formation of an Islamic Caliphate after they captured the Iraqi city of Mosul in June 2014.
In response, tens of thousands of Shia men joined a complex patchwork of militias to fight against IS. Many of these militias are notoriously violent and directly loyal to Iran’s theocratic state.
But very little is known about how these Shia militias were so quickly and so effectively mobilised. In our research, we have taken a novel approach, examining the many popular music videos produced by these militias.
