Abstract: This study describes the legal and religious plurality of the Christianity of the Holy Land in the context of the fifth crusade through the work of Jacques de Vitry, Olivier le Scolastique, and the Chronique d’Ernoul. This space, to which Muslims also lay claim, was to be fully unified and reintegrated into the Western politico-juridical order by Latin culture, then to serve as an extension of Christianity towards Egypt, India, and the confines of the world known and evangelised by the first apostles.
