Micronations/Micronational war/First Conch-American War

The First Conch-American War was a one-minute-long war between the Conch Republic and the United States. It ended in a Conch defeat.

Provoking factors
In 1982, the United States Border Patrol set up a roadblock and inspection point on US 1 just north of the merger of Monroe County Road 905A/Miami-Dade County Road 905A onto US 1 (they are the only two roads connecting the Florida Keys, where the Conch Republic is now located, with the mainland), in front of the Last Chance Saloon just south of Florida City. Vehicles were stopped and searched for narcotics and illegal immigrants. The Key West City Council complained repeatedly about the inconvenience for travelers to and from Key West, claiming that it hurt the Keys' important tourism industry. Eastern Air Lines, which had a hub at Miami International Airport, saw a window of opportunity when the roadblocks were established; Eastern became the only airline to establish jet service to Key West International Airport, counting on travelers from Key West to Miami preferring to fly rather than to wait for police to search their vehicles.

Secession and war
When the City Council's complaints went unanswered by the federal government and attempts to get an injunction against the roadblock failed in court, as a form of protest Mayor Dennis Wardlow and the Council declared Key West's independence on April 23, 1982. In the eyes of the Council, since the federal government had set up the equivalent of a border station as if they were a foreign nation, they might as well become one. As many of the local citizens were referred to as Conchs, the new nation took the name of the Conch Republic.

As part of the protest, Mayor Wardlow was proclaimed Prime Minister of the Republic, which immediately declared war against the U.S. (symbolically breaking a loaf of stale Cuban bread over the head of a man dressed in a naval uniform), quickly surrendered after one minute (to the man in the uniform), and applied for one billion dollars in foreign aid.

Aftermath
Soon after the conclusion of the war, the roadblock and inspection station were removed. The secession of the Conch Republic also resulted in the creation of a new avenue of tourism for the Keys, as henceforth anyone visiting Key West would be visiting a foreign nation, which many people relished just for its novelty.
