The Battle of Benevento was a decisive engagement fought near the town of Benevento in the Kingdom of Italy. On this occasion, Charles of Anjou, Count of Anjou and Provence, opposed Manfred, King of Sicily, who had claimed authority over the island and parts of the mainland. The backdrop of this battle was complex, involving political and territorial disputes fueled by the power vacuum created after the death of the German Emperor Frederick II. Charles aspired to counter Manfred's rule, seeking to dominate the region and expand his influence significantly.

On the battlefield, Charles's forces met the combined armies of Manfred, which included a mix of German and Sicilian troops. The confrontation proved brutal, and combatants fought fiercely for control. Ultimately, Charles emerged victorious, which not only secured his claim over Sicily and Naples but also eliminated Manfred as a rival. The death of Manfred in battle was particularly noteworthy, as it marked a significant shift in power dynamics in Italy and the surrounding regions.

Pope Clement IV, taking advantage of the changed political landscape, recognized Charles's authority over the newly acquired territories and formally invested him as king. This endorsement by the papacy significantly bolstered Charles's legitimacy, further entwining the monarchy with papal support. The implications of this battle were felt throughout Italy, instigating a series of events that would reshape the political landscape for years to come.
