Peter II of Aragon

Peter II the Catholic (1178–1213) was King of Aragon and Count of Barcelona from 1196, the eldest son of Alfonso II. He married Marie of Montpellier in 1204, who bore him his heir James I.

In 1205 he was crowned in Rome by Pope Innocent III, the first Aragonese king to receive papal coronation, and placed Aragon under the Holy See. He fought at Las Navas de Tolosa in 1212, then intervened against Simon de Montfort's Albigensian Crusade to protect his vassal Raymond VI of Toulouse, and was killed at Muret on 12 September 1213.
