If you've got issues with your country, you can picket city hall, write a strongly written letter, or simply secede to become your own micronation. That is exactly what Leonard Casley did in Australia when he had a dispute with the government of Western Australia regarding wheat quotas.
Such a boring argument ended up creating the 29 square mile nation of Principality of Hutt River in 1970. The Casley family had 4,000 hectares of wheat ready to harvest when a quota was put in place, allowing them only to sell 40 hectares. After some nasty bureaucratic nonsense that resulting in nothing, Casley and his associates went with a higher power, the International Law, which allowed them to declare their independence from the Commonwealth of Australia, though they remained loyal to Queen Elizabeth II.
Casley, now "His Majesty Leonard I of Hutt," officially declared war on Australia after the Australian Taxation Office demanded taxes from the province in 1977. It was simply some legal maneuvering to set a persuasive precedent for international recognition of his principality under the Geneva Convention. Today the residents still lodge income tax forms, but are classified a non-residents of Australia, thus their income in exempt from Australian taxation.
The principality, though it has its own capitol, currency, and a bill of rights, only has 23 actual residents.
