Many treaties, including the Treaty of Versailles, have dealt with the open seas, and currently the United Nations Convention on the Law of the Sea formalizes this freedom. Historically, many powers attempted to extend command of the sea into peacetime, imposing taxes or other restrictions on shipping using areas of open sea. For example, Venice claimed the Adriatic, and exacted a heavy toll from vessels navigating its northern waters. Genoa and France each claimed portions of the western Mediterranean.

Gulf of Suez Rift the area now occupied by the rift was a shallow sea depositing carbonates. This period was mainly quiet tectonically but the northern part of the gulf region was affected by periodic far-field effects of the Alpine orogeny. A series of WSW-ENE trending extensional basins were inverted, creating isolated uplifted and folded areas known as 'Syrian arc' structures. These structures were mainly active during the Late Santonian but there is evidence of further movements on the same structures at the end of the Cretaceous and during the Paleogene. Rifting began along the whole of the Red Sea -Gulf of Suez rift
