This book traces the trajectory of militant jihadism to show how violence is more intentionally embraced as the centre of worship, social order and ideology. Undertaking an in-depth analysis of militant jihadist groups and utilising the work of René Girard, Joel Hodge argues that the extreme violence of militant jihadists is a response to modernity in two ways that have not been sufficiently explored by the existing literature. Firstly, it is a manifestation of the unrestrained and escalating state of desire and rivalry in modernity, which militant jihadists seek to counter with extreme violence. Secondly, it is a response to the unveiling and discrediting of sacred violence, which militant jihadists seek to reverse by more purposefully valorising sacred violence in what they believe to be jihad. Relevant to anyone interested in Islam, philosophy of religion, theology, and terrorism, imagines new ways of thinking about militancy in the name of Islam in the twenty-first century.
