The Principality of Sealand is a tiny, self-proclaimed nation that started on an old sea fort in the North Sea. A former British Army major declared it independent in 1967, and it's known for its quirky history. Even though it hasn't become a recognized country globally, Sealand has its own currency, passports, and devoted fans. In fact, for £99.99 you can become a knight of Sealand! It's a unique story of a small place dreaming big and capturing people's imaginations.
