Ramiro II (c. 900 – 1 January 951), son of Ordoño II and Elvira Menendez, was a King of León from 931 until his death. Initially titular king only of a lesser part of the kingdom, he gained the crown of León (and with it, Galicia) after supplanting his brother Alfonso IV and cousin Alfonso Fróilaz in 931. The scant Anales castellanos primeros are a primary source for his reign.
He actively campaigned against the Moors, who referred to him as the Devil due to his ferocity and fervor in battle. He defeated the hosts of the Umayyad caliph, Abd al-Rahman III, at the Battle of Simancas (939).
