Here’s an interesting article on the Top Ten Bizarre Wars, such as this one:
In 1883, the citizens of Lijar, a small village in southern Spain were infuriated when they heard reports that, while visiting Paris, the Spanish king, Alfonso XII had been insulted and even attacked in the streets by Parisian mobs. In response, the mayor of Lijar, Don Miguel Garcia Saez, and all 300 citizens of Lijar declared war on France on October 14, 1883. Not a single shot was fired, and not a single casualty sustained on either side during the confrontation, but despite the anticlimactic war, Mayor Saez was declared “The Terror Of The Sierras,” for his exploit.
A full ninety-three years later, in 1976, King Juan-Carlos of Spain made a trip to Paris, during which he was treated with great respect by the citizens of the French capital. In 1981, the town council of Lijar ruled that “in view of the excellent attitude of the French,” they would end hostilities and agree to a ceasefire with France.War duration: (1883-1981) Ninety-eight years.
Casualties: None.
Others on the list, such as the Great Paraguayan War are not so happy. Its all good fodder for gaming.
