Ordoño III of León

Ordoño III (c. 926–956) was the King of León from 951 to 956, son and successor of Ramiro II (931–951). He confronted Navarre and Castile, who supported his half-brother Sancho the Fat in disputing Ordoño's claim to the throne.

He also had to deal with internal rebellion, attacks from the Muslims of al-Andalus, and the rebellion of Galicia. In response to the Muslims, Ordoño III led a raid as far as Lisbon (955), coming back north with a very lucrative haul of loot. Faced with this great show of force, Abd-al-Rahman III (912–961) was pushed to negotiate and conclude a peace treaty with the king of León.
