The Battle of Muret, fought on 12 September 1213 near Muret, 25 km south of Toulouse, was the last major battle of the Albigensian Crusade and one of the most notable pitched battles of the Middle Ages. Although estimates of the sizes of the respective armies vary considerably even among distinguished modern historians, it is most well known for a small force of French knights and crusaders commanded by Simon de Montfort the Elder defeating a much larger allied army led by King Peter II of Aragon and Count Raymond VI of Toulouse.
