In 1942, during World War II, the British government set up a small base in the North Sea just outside British territorial waters (at the time). After the war, the fort was abandoned, but, in 1967, Roy Bates, a pirate radio broadcaster, claimed it as the Principality of Sealand. The British government’s stated view is that Sealand is within British jurisdiction. Sealand generally is classified as a micronation (a nation project set up by an individual or group, and has no international recognition.)

As pertaining to the anthem, it was composed by London composer Basil Simonenko in conjunction with the governing Bates family, and has no words. The title of the anthem is also the motto of Sealand.

Principality of Sealand: The Principality of Sealand (/ˈsiːˌlænd/) is a micronation that claims HM Fort Roughs (also known as Roughs Tower), an offshore platform in the North Sea approximately 12 kilometres (7.5 mi) off the coast of Suffolk, as its territory. Roughs Tower is a Maunsell Sea Fort that was built by the British during World War II. Since 1967, the decommissioned Roughs Tower has been occupied and claimed as a sovereign state by the family and associates of Paddy Roy Bates. Bates seized Roughs Tower from a group of pirate radio broadcasters in 1967 with the intention of setting up his own station there. Sealand was invaded by mercenaries in 1978, but was able to repel the attack. YouTube Link https://www.youtube.com/watch?v=EPicttbeI_c
