Despite numerous sources suggesting that Islamophobia is becoming both increasingly prevalent and societally acceptable in the contemporary world, there remains a lack of textual sources that consider either the phenomenon itself, or its manifestations and consequences. There is no authoritative text that attempts to understand or contextualise what might be seen to be one of the most dangerous prejudices in the contemporary climate. Chris Allen begins by looking at ways of defining and understanding Islamophobia. He traces its historical evolution to the present day, considering the impact of recent events and their aftermath especially in the wake of the events of September 11, before trying to understand and comprehend a wider conception of the phenomenon. A series of investigations thematically consider the role of the media, the contemporary positioning of Muslims throughout the world, and whether Islamophobia can be seen to be a continuum of historical anti-Muslimism or anti-Islamism, or whether Islamophobia is an entirely modern concept. The issue of Islamophobia is considered from the perspective of the local, regional, and global. The incidence of Islamophobia, and the magnitude of the phenomenon and its consequences, is one that warrants a greater investigation in the world today.
