Guelphs and Ghibellines
The Battle of Zappolino, the only battle of the War of the Oaken Bucket, was fought in November 1325 between forces representing the Italian towns of Bologna and Modena, an incident in the series of raids and reprisals between the two cities that were part of the larger conflicts of Guelphs and Ghibellines. The Modenese were victorious. Though many clashes between Guelphs and Ghibellines loomed larger to contemporaries than to historians, the unusually-large encounter involved 4000 estimated cavalry and some 35,000 foot soldiers, and 2000 men lost their lives. The location of the battle, at the foot of a hill just outside the castle walls, is now a "frazione" of the municipality of Castello di Serravalle, Emilia-Romagna.
