Tobias P. Graf is a Research Associate in Early Modern History at Heidelberg University and an Associate Member of the Cluster of Excellence "Asia and Europe in a Global Context". He read history at the University of Cambridge before transferring to Heidelberg, where he was part of an interdisciplinary research group which investigated cultural exchanges between Christian Europe and the Ottoman Empire. Graf has a profound interest in transregional entanglements within and beyond the boundaries of the European continent. He is currently working on a study of Austrian-Habsburg foreign intelligence during the reign of Emperor Maximilian II.

"The study illuminates the relationship between con?icting religious truths and state formation through the lens of individual converts and their careers. â [The book] provides fascinating insights into the culture of conversion and an early modern Christian-Islamic cosmopolitanism." -- Alexander Schunka , Journal of Ecclesiastical History

"Graf's The Sultan's Renegades is an important addition to recent research on the topic and is the first to focus on converts' assimilation into the imperial structures. Its publication stresses the relative dearth of similar studies focusing on the Western Mediterranean in the period. The Sultan's Renegades will be of great interest for scholars of the Ottoman Empire, Mediterranean studies, religion and conversion, cross-confessional encounter, and cultural intermediaries." -- Daniel Hershenzon, Renaissance Quarterly

"Many renegades led a double life. With a foot in two rival worlds, they formed a 'trans-imperial' society of their own which Tobias Graf engagingly explores." --Alastair Hamilton, Times Literary Supplement

"He [Graf] skilfully analyses the data at his disposal" --Emrah Safa Gürkan, Journal of Early Modern History

"an essential reference and, most likely, a turning point in the debates to come." --Medieval Review

"This book is a fine example of the pioneering efforts to expand our understanding of the complex interactions between Christian Europe and the Ottoman world in the early modern era." -- Andrew L. Thomas, The Sixteenth Century Journal
