14 cargo ships were stranded in the Suez Canal for 8 years, whose crews all decided to form a micronation. One ship served as a hospital; another, a movie theater. On Sundays, the German Nordwind hosted “church” services. “We call it church,” Captain Paul Wall told the Los Angeles Times in 1969. “But actually it is more of a beer party.” (The Germans received free beer from breweries back home.)
The micronation of the Conch Republic seceded from the United States in 1982. They declared war on April 23rd 1982 and surrendered 1 minute after the declaration so they could apply for foreign aid.
In 1968 a man built an island off the coast of Italy and declared himself the President. He ran a restaurant, a bar, a nightclub, and a post office on the island. The Italian government didn’t like this, seized control of the island, and literally blew it up the next year.
There is a micro nation in Nevada named Molossia that consists only of a house, front yard and back yard. It also declared war on east Germany.
A floating British base was abandoned until a rogue DJ moved there. He declared the floating fortress the Principality of Sealand. He raised a flag, named himself Prince and his wife Princess. Sealand withstood court challenges, and remains an independent nation to this day.
