Book excerpt: This volume shows the diversity of approaches to violence in Islamic thought between the 19th century and the present day, avoiding the limiting characterisations of Islam being inherently 'violent' or 'peaceful'. It shows how ideas of 'justified violence' - grounded in Islamic theological and juristic traditions - reoccur throughout history, up to the contemporary period. Chapters on earlier events provide context for contemporary debates on violence, showing how traditional legal and theological ideas (such as the sovereignty of God's law and peace treaties) are used to both legitimise and de-legitimise violence.
