First published in 1907, this book provides a history of the political relations between the states founded by Crusaders and the Islamic states with which they waged war. In the treatment of this subject the Eastern point of view is emphasized and the main thread of narrative is drawn, as far as possible, from the history of Islamic states. Additional material includes appendices relating to chronology, a list of principal works referred to in the notes, an index, and maps. This book will be of value to anyone with an interest in the history and historiography of the Crusades.
