TIL that the city of Huescar forgot they were at war with Denmark until a local historian found the declaration 172 years later. No shots were fired during the war.

"Between 1809 and 1981, Huéscar was at war with Denmark, as a result of the Napoleonic wars over Spain, where Denmark supported the French Empire.

This official declaration of war was forgotten until it was discovered by a local historian in 1981, followed by the signing of a peace treaty on 11 November 1981 by the city mayor and the Ambassador of Denmark.

Not a single shot was fired during the 172 years of war, and nobody was killed or injured."
