The Battle of Alameda, also known as the Battle of al-Musarah or Battle of Almuzara (Arabic: معركة المصارة), was fought between the Umayyads and Fihrids in 14-15 May 756 CE near Córdoba. It formed part of the process by which ʿAbd al-Raḥmān I al-Dākhil established an independent Umayyad emirate in al-Andalus, separate from the newly established Abbasid Caliphate based in Iraq which had overthrown the preceding Syria-based Umayyad Caliphate.
