This is a border dispute that ended up in the creation of a tiny sovereign country. During the Yugoslav War in the 90’s, when the area was broken up into the smaller countries of Slovenia, Croatia, Serbia, Bosnia, Montenegro and Macedonia, the borders were fluid and constantly under dispute. There’s an area of four square miles between Croatia and Serbia that neither side wants to claim.

This area was considered “terra nullius,” or “no man’s land” until April 2015, when a Czech political activist moved in and called it the “Free Republic of Liberland.” He developed a flag, set up a government and demanded recognition. Right now, the only way to get there is by the Danube River, as both Croatia and Serbia won’t allow anyone to cross the border into Liberland. So neither side wants it, but won’t let the other side have it, nor anyone else have it.

That’s a preschool fight, if I’ve ever heard one.
