The author pays particular attention to the complex relationship between Byzantium and the Crusaders. By investigating the deep-rooted contradictions between the two sides, the paper reveals the hostile relationship between the Byzantine Empire and Crusader leaders during the Crusades. Drawing upon Anna Komnene¡¯s Alexiad and other sources, this report further analyzes the defamatory propaganda spread by Crusader leaders such as Bohemond I against the Byzantine emperor Alexios I, as well as the influence of such propaganda on subsequent Crusades. The paper also points out the limitations of Morrisson¡¯s work and, by incorporating the perspectives of Peter Frankopan, comprehensively discusses the origins and evolution of the contradictions between the Crusaders and Byzantium. %K Crusades %K Byzantine Empire %K C¨¦cile Morrisson %K Alexios I %K Bohemond %K Anna Komnene %K Contradiction %K Defamatory Propaganda %U http://www.scirp.org/journal/PaperInformation.aspx?PaperID=152434
