This volume was developed as a part of the “Politics of Religion at Home and Abroad” project funded by the Luce Foundation’s Initiative on Religion in International Affairs. We gratefully acknowledge their support, and particularly that of Dr. Toby Volkman who has been a wonderful colleague to us for many years. We would like to thank Sarah Dees, Luce Postdoctoral Fellow, for her many contributions to this project, and Matthew Graham for his excellent editorial assistance in the production of this volume. The editorial team at Indiana University Press, including Dee Mortensen, Michael Regoli, Ashante Thomas, and Daniel Pyle, has made experimenting with a new publishing format a pleasure. We are grateful for their time and patience. Thanks to Emily Stratton for the wonderful cover photo, and to the Department of Political Science and the Weinberg College of Arts and Sciences at Northwestern University and the Department of Religious Studies at Indiana University for their support for this work. Thanks to The Immanent Frame, the Social Science Research Council’s online discussion forum on religion and public life, where early versions of this text appeared. Finally, we are grateful to each of our contributors for taking the time to explore this topic, and this new format, with us.
