Micronations, sometimes known as unrecognized nations or ephemeral states, are countries which claim status as independent nations, but which lack diplomatic recognition by the world community. Many claim some physical land area as their national territory; others are non-territorial, existing only in the virtual world. These nations may represent true secessionist movements, experiments with political and governmental models, or extended jokes. The line between serious and whimsical micronations is often a thin one.
