A micronation is a political entity whose representatives claim that they belong to an independent nation or sovereign state, but which lacks legal recognition by any sovereign state. Micronations are classified separately from de facto states and quasi-states; they are also not considered to be autonomous or self-governing as they lack the legal basis in international law for their existence. The activities of micronations are almost always trivial enough to be ignored rather than disputed by the established nations whose territory they claim—referred to in micronationalism as macronations. Several micronations have issued coins, flags, postage stamps, passports, medals and other state-related items, some as a source of revenue. Motivations for the creation of micronations include theoretical experimentation, political protest, artistic expression, personal entertainment and the conduct of criminal activity. The study of micronationalism is known as micropatriology or micropatrology.
Although several historical states have been retroactively called micronations, the concept was formulated in the 1970s, with a particular influence from the International Micropatrological Society. Micronationalism saw several developments thereafter, with several micronations being founded in Australia in the 1970s and Japan in the 1980s. As a result of the emergence of the World Wide Web in the mid-1990s, micronationalism lost much of its traditionally eccentric anti-establishment sentiment in favour of more hobbyist perspectives, and the number of exclusively online or merely simulation-based micronations expanded dramatically. This has allowed several intermicronational organisations to form, as well as allowing for many diplomatic summits to take place between micronations since the 2000s, including the biennial MicroCon convention.
