The 1315 Battle of Montecatini produced a decisive upset when Pisa's forces under the warlord Uguccione della Faggiuola routed the larger Guelph army of Florence and the Kingdom of Naples, killing the brother of King Robert of Naples and several other noble commanders. The victory temporarily shifted the balance of power in Tuscany away from the dominant Florentine republic, though Uguccione was overthrown by his own city within a year. The engagement demonstrated the volatile nature of Italian city-state politics, where military victory provided no guarantee of lasting political control.
