The first is the many students to whom I have taught Islamic history and who have helped me think about the shortcomings of the traditional narrative. The Oxford graduate intake of 2010–11 were particularly influential, for I was then fully engaged in writing this book and we discussed some of its aspects in our seminars, so thank you Anna, Benedict, Charlie, Hasnain, Josh, and Ryan. The second is my undergraduate teacher and doctoral supervisor, Patricia Crone, who first introduced me to Islamic history and encouraged me to think critically about its origins and formation. In addition, there are the many colleagues with whom I have had interesting discussions that have helped shaped some of the ideas presented in this book. Although there are too many to name them all here, I would particularly like to thank Aziz al-Azmeh, Amikam Elad, James Howard-Johnston, Hugh Kennedy, Marie Legendre, Milka Levy-Rubin, Andrew Marsham, Fergus Millar, Harry Munt, Arietta Papaconstantinou, Richard Payne, Gabriel Reynolds, Christian Robin, Sarah Savant, Petra Sijpesteijn, Adam Silverstein, Jack Tannous, David Taylor, Luke Treadwell, and Kevin van Bladel. Of course, none are responsible for how I have used the wisdom that they imparted to me. My editor Stefan Vranka and reader Robin Wakefield put in a lot of work to improve this book’s x A C K N O W L E D G M E N T S coherence and readability, and Michael Athanson gave freely of his time and expertise to help make the regional maps. Finally I am eternally grateful to Peter Waidler for his astute and thoughtful proofreading and to Sarah for her love and support.
