Greek contemporary sources show Byzantine response to XIIth century crusade to have been more committed than is usually believed mostly following however its own specific lines. Those include tradition of going to the Holy Land for ascetic train ing imperial interest in the Holy Places and strong identification of Constantinople as the New Zio. The primacy of Jerusalem is argued against the Roman See. Response to the Crusade ranges from Imperial eschatology with Alexios and later Isaac II to taking up the actual idea with John II and splendidly wrapping it up with the universal claim of Empire with Manuel. 11 pages Source : Persée ; Ministère de la jeunesse, de l’éducation nationale et de la recherche, Direction de l’enseignement supérieur, Sous-direction des bibliothèques et de la documentation.
