The Battle of Las Babias occurred in the year 795 when the Emir of Cordoba, Hisham I of Córdoba sought to avenge his previous military incursions in 794 against the Kingdom of Asturias under the command of the brothers Abd al-Karim ibn Abd al-Walid ibn Mugaith and Abd al-Malik ibn Abd al-Walid ibn Mugaith. The previous battles resulted in devastating losses for the Emirate, most importantly at the Battle of Lutos where one of the Emir's generals was killed in action. The battle resulted in a Córdoban victory.
