Self-governing British Crown dependency in the Irish Sea
The Isle of Man (Manx: Mannin [ˈmanɪnʲ], also Ellan Vannin [ˈɛlʲan ˈvanɪnʲ]), or Mann ( man), is a self-governing British Crown Dependency in the Irish Sea, between Great Britain and Ireland. As head of state, Charles III holds the title Lord of Mann and is represented by a Lieutenant Governor. The government of the United Kingdom is responsible for the Isle of Man's military defence and represents it abroad, but the Isle of Man still has a separate international identity. Humans have lived on the island since before 6500 BCE.
