A micronation is usually referred to as either model countries and/or new country projects. They vary somewhat yet are small, self-proclaimed entities that claim to be independent sovereign states but which are not acknowledged as such by any recognised sovereign state or authority. They should not be confused with microstates, which are recognised independent states of a small size, nor should they be confused with unrecognised states, which may have legitimate claim to sovereign state status.
Motivations for the creation of micronations include theoretical experimentation, political protest, artistic expression, personal entertainment and the conduct of criminal activity. They can also exist in various forms, including in the physical world (on land, at sea and even in outer space), online, in the minds of their creators, or some combination of these. Some micronations issue coins, flags, postage stamps, passports, medals, and other items.
The two examples that are close to where I reside in Florida, are the Conch Republic and one I just became aware of, British West Florida.
