The Principality of Sealand is an unrecognised entity, located on HM Fort Roughs, a former WW II Maunsell Sea Fort in the North Sea 13 kilometres (7 nmi) off the coast of Suffolk, England, United Kingdom. This country posibly will never be member of United Nations, but in Guinius book of records is smallest country in the world.It is Sealand, a state which has all the characteristics of the state, flag, coat of arms, passport, currency and your prince and princess....

Since 1967 the facility has been occupied by family and associates of Paddy Roy Bates, who claim that it is an independent sovereign state. Bates seized it from a group of pirate radio broadcasters in 1967 with the intention of setting up his own station at the site. He established Sealand as a nation in 1975 with the writing of a constitution and establishment of other national symbols. Bates moved to mainland Essex when he became elderly, naming his son Michael regent. Bates died in 2012 at the age of 91.

While it has been described as the world's smallest nation, or a micronation, Sealand is not currently officially recognised by any established sovereign state. Although Roy Bates claimed it is de facto recognised by the United Kingdom (after an English court ruled it did not have jurisdiction over Sealand as territorial water limitations were defined at that time) this action does not constitute de jure recognition.
