Sealand is a micronation that describes itself as "a sovereign Principality in international waters, seven miles off the eastern shores of Britain". Based on HM Fort Roughs, a naval fort built to protect the Thames Estuary during the Second World War, the Principality of Sealand was established by the Bates family in 1967. after they took occupation of the disused military structure with the intention of operating a pirate radio station there.
Within their new principality, Roy Bates and his wife Joan styled themselves as Prince Roy and Princess Joan; since Roy's death in 2012, his son, Michael, has claimed the title Prince Michael. Sealand celebrated the "50th anniversary of independence" in 2017.
Sealand issued its first stamps, denominated in Sealand dollars (SX$), in 1969, with further issues following during the 1970s. A new issue was released in 2010. Sealandic stamps are considered Cinderellas, given that the Principality is not a recognised government postal administration.
The Sealand website includes more details about the micronation's history and a regularly updated news section.
