It is within this climate that Cemil Aydın has recently had his book published for a general audience titled The Idea of the Muslim World: A Global Intellectual History. I’m sure that the book will interest Islamicists, Ottomanists and general readers. In this book, through six carefully written and researched chapters, Aydın attempts to trace the genealogy of the above-mentioned sentiments back to the late eighteenth century where he argues that the notion of a Muslim world emerged when the colonial European powers exercised much political and intellectual influence that in turn fashioned a reactionary intellectual response by Muslim thinkers for a call for Muslim unity.
