The War of the Bucket or the War of the Oaken Bucket (Italian: Guerra della secchia rapita) was fought in 1325, during the Age of Assassins, between the rival city-states of Bologna and Modena. It took place in the region of Emilia-Romagna in northern Italy. The war was an episode in the over 300-year-long struggle between Guelphs and Ghibellines. Modena won the Battle of Zappolino (the only battle of the war), and the bucket remains in Modena to this day.
A common myth surrounding the War of the Bucket is that it was caused when the Modenese stole a bucket from a Bolognese well. However, this is mostly incorrect, as the bucket was (according to most accurate accounts) taken as a trophy by the Modenese after the war.
