シーランド公国
On 2 September 1967, the fort was occupied by Major Paddy Roy Bates, a British subject and pirate radio broadcaster, who ejected a competing group of pirate broadcasters. Bates intended to broadcast his pirate radio station – called Radio Essex – from the platform. Despite having the necessary equipment, he never began broadcasting. Bates declared the independence of Roughs Tower and deemed it the Principality of Sealand.
