6. The war of stray dogs was another ridiculous start for a war that was caused between Bulgaria and Greece in 1925. The dog ran towards the Bulgarian territory. It was shot by a Bulgarian border guard. The Bulgarians fired and killed the captain. A Greco-Bulgarian commission had to investigate the matter. 

The border issues were a major concern between both countries at the time. The war was due to a brief invasion during 1925 from Bulgaria to Greece. A Greek soldier was running after his dog, which accidentally strayed across the border.

The border had a Bulgarian sentry who shot the dog and the soldier. The incident led to the Greek firing volleys and Greeks running into no-man’s land. They apologized for the firing saying it was a misunderstanding. The Greek government issued an ultimatum to punish those responsible and asked for an official apology along with two million French francs. (Source) 

7. A war that was long forgotten to an extent where the city that declared war forgot to go fight. The city of Huéscar declared war on Denmark when Napoleon’s War was being conducted over Spain during 1809 even though they supported the French Empire during the war. Huéscar wanted to challenge the country. In 1981, a historian found the declaration and informed authorities. 

During the Napoleonic Wars over Spain, Huescar, a big city, fancily decided to declare war upon Denmark.

The event was immediately forgotten and wasn’t rediscovered until a local historian found the details about the war declaration in 1981. These events followed the making of a peace ceremony where the Ambassador of Denmark and the City Mayor publicly shook hands and sorted out the misunderstanding. (Source)

8. The Pastry War was one such war fought over a decade later after the incident leading to the conflict started. In 1828, a lawless mob destroyed a pastry shop in Mexico City. The concern was not taken seriously and was quickly forgotten. Years later, King Louis Philipe demanded a 90% interest rate from the baker, but they refused, blockaded Mexico city, and occupied Veracruz City. 

Mexico experienced a great deal of turmoil during the years 1838-1839. Many countries, mainly the British, French, Spanish, and the U.S, were having revolts and incidents which led to civil disorder.

The Mexican treasury was emptied to settle these conflicts, and this led to more and more tension. One such demand from a French squadron that arrived in Veracruz was to compensate a pastry chef who asked for a sum of 60,000 pesos for destroying his business several years ago.

The Mexican government declared war shortly, and Veracruz was purged of the French immediately. (Source)

9. The Kettle War happened on October 8, 1784. The name of the war is because the only shot fired hit a soup kettle. It was a confrontation between the Holy Roman Empire and the Republic of the Seven Netherlands. 

France was facing financial problems because of the expenses of the wars they were fighting. It made an alliance with Austria and was in a war for seven years straight.

In October 1781, Benjamin Franklin received a letter saying the war was inevitable. After that, they discovered a Dutch ship sent out to intercept the Imperial ships. After one shot that hit a kettle, Le Louis accepted the surrender. 

The southern Netherlands was under the Roman Empire and the Empire wanted ports in the south for opening trade but the north was stopping this. As a consequence of several short skirmishes, negotiations opened between both countries.

The Empire sent ships to the opening of the river and shots were fired, but his highly advanced ship had to surrender. Nobody died in the fight, but the incident led to other European countries discovering what was happening, and the emperor had to give up his plans. This led to favoring agreements for Belgium and Netherlands. (Source)

10. The countries Bolivia and Chile went to war over bird droppings. It might sound ridiculous to people now. The fight was, however, for a legit reason, as the excreta were used to make gunpowder. The war was from 1873-83 and was one of the deadliest wars in the 19th century. 

Chile, Bolivia, and Peru got into one of the deadliest wars ever heard of over a coastal strip filled with guano-bird droppings. The area of the Atacama Desert was scenic and home to many bird species.

The fight was over the Atacama Desert along the Pacific Coast where the bird population is large resulting in the aforementioned droppings. Apart from being a good fertilizer, it was also good for making gunpowder.

Similar riots occurred in the Chincha Islands off the coast of Peru for similar reasons. In 1904, after years of conflicts, the place got its new ruler, Chile. (Source)
