I should first of all express my sincere to Professor J. A. S. Grenville, head of the Department of Modern History at Birmingham University, for giving me invaluable advice and encouragement without which this study could not be brought to this stage. I greatly appreciate his willingness to share his extensive knowledge of methodology and British archival sources. I thank for Professor Anthony Bryer, director of the Centre for Byzantine, Ottoman and Modern Greek Studies both for allowing me to use his private books and for kindly reading the text of this study.(Önsöz'den)
