The Battle of Marj Ardabil or the Battle of Ardabil, is a battle fought on the plains surrounding the city of Ardabil in northwestern Iran in 730 CE.
A Khazar army led by Barjik, the son of the Khazar khagan, invades the Umayyad provinces of Jibal and Adharybaydjian in retaliation for Caliphate attacks on Khazaria during the course of the decades-long Khazar-Arab War of the early 700s.
