This is the kind of thing that used to start wars, but we highly doubt that this incident will come to that. A farmer who was annoyed by a historic stone marker that was in his tractor’s path moved the object 7.5 feet — unofficially making his own country of Belgium slightly bigger and neighboring France slightly smaller.

Farmers are notoriously protective of their land rights; sovereign nations tend to be, too. As you can imagine, the incident has raised some eyebrows.

First reported by the BBC, the news outlet said that the border between France and what is now Belgium was formally established under the Treaty of Kortrijk, signed in 1820 after Napoleon’s defeat at Waterloo five years earlier. The stone, which is between the Belgian town of Erquelinnes and the French town of Bousignies-sur-Roc, dates back to 1819, when the border was first marked out.
