Abstract EN

This research aims to clarify the nature of the relations between the Kingdom of Jerusalem and the Crusader emirates with the forces surrounding it in the Islamic East, and the military alliances that resulted from these relations, which led to the preservation and continuity of the Crusader emirates, by analyzing these alliances to reach the conclusions that lead to success The alliance or its failure, whether these alliances were with a Latin, Orthodox, or Islamic Crusader force, through the historical research approach, the critical approach, and the descriptive approach.

This was concentrated during the reign of Kings Baldwin I and Baldwin II, and the lack of seriousness of the Crusaders in their alliance with the Byzantine power was due to their fear of the possibility of the Byzantine emperor controlling the Crusader emirates, and that the success of the Crusader alliances with some Islamic cities and powers was due to the state of division and weakness that was Islamic cities, as these alliances began to lose their value when a dominant Islamic leadership emerged.
