FAQ
Frequently Asked Questions
No, it is a historical concept. Modern international law, under the United Nations Convention on the Law of the Sea (UNCLOS), establishes a standard territorial sea of 12 nautical miles for most nations.
It was derived from the 'cannon shot rule' proposed by Dutch jurist Cornelius van Bynkershoek in the early 18th century. Three nautical miles was considered the approximate maximum range a shore-based cannon could fire, thus defining the zone a coastal state could effectively control and defend.
No. While it was adopted by many maritime powers like Britain and the United States in the 18th and 19th centuries, some nations, particularly in Scandinavia and Latin America, historically claimed broader territorial seas for fishing and security reasons.
In this term, 'mile' specifically means a *nautical mile* (approximately 1.852 kilometres or 1.15 statute miles). A statute mile (used on land) is shorter (approx. 1.609 km). The three-mile limit is therefore about 5.56 km from shore.
