Global wars fought for stupid reasons

The Pig War In 1859 the killing of a pig on San Juan Island brought England and the United States to the brink of war over the issue of territorial rights here, where both sides lay claim on the island.

War of the Bucket In 1325, the cities of Modena and Bologna went to war after Modenese soldiers stole a bucket from Bologna.

War of the Stray Dog A war started in 1925 between Greece and Bulgaria because a stray dog from Greece crossed the border. A Greek soldier ran after the dog, but was shot by the Bulgarian army after seeing the soldier nearing their territory. Soon the Greeks invaded Bulgaria and occupied border towns and preparing to shell the city

The Nika Riot Massive mob flooded the streets of Constantinople in 532 AD, burning large parts of the city, toppling the governmen of the Emperor Justinian, all in the name of chariot racing.

The War of Jenkins' Ear In 1738, a British mariner named Robert Jenkins displayed a severed, decomposing ear before the members of Parliament. He claimed that a Spanish coastguard officer sliced off his ear seven years earlier as punishment for smuggling. Spurred on by this stirring testimony, the British soon declared war on the kingdom of Spain. Thus began the outlandish “War of Jenkins’ Ear.”

The Toledo War An argument began over a border strip called the 'Toledo' dividing the two states of Michigan and Ohio. A heated border dispute ensued where both sides laid claims over the Toledo strip

The Pastry War In 1828, angry mobs destroyed large parts of Mexico City during a military coup. One of the victims of the rioting was an expatriate French pastry chef named Remontel, whose small café was ransacked by looters. Mexican officials ignored his complaints, so Remontel petitioned the French government for compensation. 

The Pastry War (continued) His request sat unnoticed until a decade later, when it came to the attention of King Louis-Philippe. The king was already furious that Mexico had failed to repay millions in loans, and now he demanded they pay 600,000 pesos to compensate the pastry chef for his losses. When the Mexicans balked at handing over such an astronomical sum, Louis-Philippe did the unexpected: He started a war.
