jdavidb writes "46 years ago, occupying an abandoned WWII platform off the coast of Britain, Paddy Roy Bates declared independence, naming himself Prince of the Principality of Sealand. Today, Bates has passed away at 91. Long time Slashdot readers will remember Sealand as the site of HavenCo, an unsuccessful data warehousing company that tried to operate from Sealand outside the reach of larger nations' legal structures. They may also remember plans that the Pirate Bay had at one time to buy Sealand. Bates had moved to a care home a few years ago, naming his son Michael Regent of Sealand."
