Responses to this study were very supportive. Very many people were willing to share the story of their conversion to Islam and also to provide other rele- vant information contained in this work. I thank all my interviewees who allowed their recollections to be reflected in these pages. For those who wished to remain anonymous, I am equally grateful for their testimonies, for the warmth of their reception and their remarkable patience in answering my queries. I also thank all my research assistants—Calista, Kelechi, Nnennaya, and Obinna— and some of my students in the Department of History and International Studies, University of Nigeria, who contributed to the fieldwork by selectively inter- viewing contacts in various towns or informing me of such individuals. Our efforts together ensured a reasonably wide coverage of Igboland and Eastern Nigeria that this study warranted, but more importantly the enthusiasm of my research team was of considerable encouragement to me. Worth mentioning, too, is the support of my University administration in approving the long research leave that was devoted to this study.
