In 1325, a bloody war broke out between the Italian city-states of Bologna and Modena. According to legend, the conflict was ignited when Modenese soldiers stole an oak bucket from a Bolognese well. Though the underlying tensions were political, the bucket remains on display in Modena to this day.
The Legend of the Stolen Pail
Popular lore holds that in the late autumn of 1325, an audacious group of soldiers from the northern Italian city of Modena slipped into the rival city of Bologna under cover of darkness. Instead of looting gold, raiding armor, or capturing noble hostages, the intruders allegedly targeted a municipal public well. They unhooked an ordinary wooden bucket made of oak, loaded it with whatever plunder they could carry, and carried it back across the border. Incensed by the sheer disrespect of the act, Bologna supposedly demanded the bucket's immediate return, and when Modena refused, declared a full-scale war that cost thousands of lives.
While this story is one of the most famous anecdotes in medieval European military history, the narrative gets the chronology backwards. The war did not erupt because of an abducted water bucket; rather, the bucket became a trophy of a brutal, pre-existing ideological conflict. The true origin of the hostilities lay in centuries of deep-seated geopolitical rivalry, border skirmishes, and the bloody factional split between the partisans of the Papacy and the Holy Roman Empire that tore medieval Italy apart.
Guelphs, Ghibellines, and Divided Cities
To understand the War of the Bucket, one must look to the broader struggle between the Guelphs and Ghibellines, two warring factions whose disputes dominated Italian politics from the twelfth to the fourteenth centuries. In simplistic terms, Guelphs aligned themselves with the authority of the Pope, while Ghibellines supported the secular authority of the Holy Roman Emperor. In practice, however, these allegiances often served as convenient banners for neighboring communes to justify territorial ambitions, commercial competition, and long-standing family blood feuds.
Bologna and Modena sat barely forty miles apart on the fertile plains of the Emilia-Romagna region, yet they stood on opposite sides of this violent ideological divide. Bologna was a proud and powerful Guelph stronghold, firmly backing the Papacy and serving as a central hub for papal interests in northern Italy. Modena, conversely, was fiercely Ghibelline, aligned with imperial power and governed by local warlords who saw Bolognese regional dominance as an existential threat to their independence.
By the early fourteenth century, tension along the border between the two communes had escalated steadily. Shifting alliances, raids on border garrisons, and clashes over strategic castles created a powder keg that required only the slightest push to ignite into open, regional warfare.
The Escalation of 1325
The flashpoint came under the leadership of Rinaldo Bonacolsi, known as Passerino, the lord of Mantua and Modena. Bonacolsi was an aggressive Ghibelline commander who actively expanded his influence throughout Emilia-Romagna, frequently threatening Bolognese territories. Throughout the summer and early autumn of 1325, border friction intensified as both sides raided farming villages, burned crops, and seized fortified frontier outposts.
Bolognese troops responded by launching counter-raids deep into Modenese lands, ravaging the countryside to punish Bonacolsi and assert Guelph supremacy. Pope John XXII, reigning from Avignon, actively supported the Bolognese efforts, seeking to crush the Ghibelline coalition in northern Italy once and for all. What had begun as routine border harassment rapidly mobilized into a massive military expedition, with both sides calling upon their regional allies for a decisive confrontation.
The Decisive Clash at Zappolino
In November 1325, the two armies met at the foot of the Apennine hills near the fortified castle of Zappolino. The resulting Battle of Zappolino was one of the largest field engagements in medieval Italian history. Bologna fielded an enormous army, estimated at around thirty thousand infantry and two thousand cavalry, vastly outnumbering the Modenese force, which counted roughly five thousand foot soldiers and under three thousand cavalry. Despite being heavily outnumbered, the Modenese force benefited from experienced, heavily armored cavalry and cohesive leadership under Bonacolsi and allied imperial captains.
The battle unfolded rapidly in the fading daylight. Modenese cavalry launched a ferocious, disciplined charge that struck the flank of the Bolognese lines before the larger army could effectively coordinate its superior numbers. Panic spread through the Bolognese ranks, turning an orderly formation into a chaotic rout. The Modenese pursued the fleeing Guelph soldiers all the way back to the city gates of Bologna, leaving thousands dead on the battlefield and capturing scores of wealthy Bolognese nobles as hostages.
The True Story of the Bucket
Having routed their rivals and pursued them to the very walls of Bologna, the Modenese soldiers did not attempt a protracted siege of the well-defended city. Instead, they spent several days devastating the surrounding countryside, destroying smaller forts, and mocking their defeated enemies. As part of this celebration, Modenese troops took a simple oak bucket from a well located outside one of Bologna's city gates.
The bucket was carried back to Modena not as the catalyst of the war, but as a deliberate emblem of humiliation. By displaying an ordinary, utilitarian object taken from beneath the noses of Bologna's defenders, Modena demonstrated that it could ride right up to the city's gates with total impunity. The bucket was hung as a public war trophy in Modena's cathedral, and later preserved in the Torre della Ghirlandina, where a replica remains on public display to this day.
Satire and the Birth of a Myth
The enduring misconception that the bucket caused the conflict stems largely from Italian literature rather than fourteenth-century chronicles. In 1622, more than two centuries after the battle, the Modenese poet Alessandro Tassoni published a mock-heroic epic titled *La secchia rapita* (The Stolen Bucket). Tassoni took the real historical clash at Zappolino and framed it as an absurd, Homeric war triggered entirely by the theft of a wooden bucket, populated by bumbling warriors, meddling Olympian gods, and ridiculous political posturing.
Tassoni's poem was a massive literary success across Europe, helping to popularize the mock-heroic genre. Over the generations, however, the satirical premise of the poem merged with genuine public memory, leading many to believe that the war really had been fought over a bucket. In reality, the War of the Bucket was a deadly chapter in the grand geopolitical struggle between the Pope and the Emperor, remembered through the lens of a single, well-preserved symbol of medieval mockery.
Key takeaways

•The Modenese took the oak bucket as a mocking trophy after winning the major Battle of Zappolino in November 1325.
•The popular myth that the bucket caused the war was popularized centuries later by Alessandro Tassoni's 1622 satirical epic poem, *La secchia rapita*.
•The original bucket was preserved for centuries in Modena, where a replica remains displayed in the Torre della Ghirlandina.
