The author addresses the issue of Jerusalem and proposes solutions based on international law. Jerusalem has great significance on several levels: local / municipal, and so functional for the residents, the national level where the issue of sovereignty is important, and finally the international level related to the holy places for all three religions. The author therefore analyzes the historical claims of two parts, the first of 1947, the idea (ideal) of Jerusalem an international city in 1949 and the first occupation, the second occupation of 1967, the Declaration of Principles of 1993 (Oslo agreement ), the Road Map, the Geneva Agreement. And, finally considered as decisive of sovereignty, a "division" non-physical (i.e. without boundary) of Jerusalem, especially from the standpoint of international law
