This book addresses the greatest source of societal tensions and violent conflict in contemporary Europe, involving people from minority groups of Muslim culture. Six country case studies – on Belgium, France, the Netherlands, Spain, Russia and the United Kingdom – give a comprehensive account of Islam-related tensions and violence, from the jihadist terrorist acts seen in Europe in the aftermath of 9/11 in the US, through to the urban riots of the type seen in France in 2005. These events are analysed with a common typology together with detailed accounts of the social context in each country. Also included is an interpretation of the fundamental nature of the Islamist terrorism in Europe, with the outline of a strategy to repel it. The book is a unique source for those seeking to understand the nature of ethno-religious violence in contemporary Europe.
