Mare Clausum: The Legal Definition and Implications of Closed Seas
Definition & Meaning
Mare clausum refers to a body of water that is closed to navigation by other states and is under the jurisdiction of a specific nation. This term is often used in international law to describe territorial waters, which are the areas of the sea adjacent to a country's coastline. These waters are not accessible to foreign vessels without permission, distinguishing them from international waters, which are open to all.
