The Map Error That Created a Country

Oddities

A clerical mistake is usually a headache. In the case of Cospaia, it was a masterclass in accidental sovereignty. Two powers messed up a border redistribution and left a tiny strip of land in Italy completely unclaimed. The result? A de facto independent republic that lasted 386 years. No formal government. No police force. Just a tax free haven for tobacco growers. Who actually needs a bureaucracy when a map error does the heavy lifting? The Italian Wikipedia page has the details. Does anyone have links to other geopolitical glitches like this?
