Sealand is an offshore platform located in the North Sea.
It was built by the British during World War II as an army and naval fort, and was asked to be demolished after World War II because it was out of UK waters.
But in 1967, Sealand was occupied by a man named Paddy Roy Bates, who declared it a sovereign country.
Since then, Sealand has been acting in defiance of the UK government for 54 years.
It has its own constitution, a national flag and even a national anthem. Its motto is ‘Freedom from the Sea’.
