The Battle of Balanjar was a battle in the Khazar–Arab Wars. In 722 or 723, according to Muhammad ibn Jarir al-Tabari, Umayyad soldiers under al-Jarrah ibn Abdallah crossed the Caucasus Mountains and attacked Balanjar. The inhabitants of Balanjar tried to defend their town by fastening 3,000 wagons together and circling them around the key fortress on high terrain, but were defeated in the attack. The Arabs massacred much of the town's population; survivors fled to other towns, including Samandar. The victorious Arab army stole much booty and the soldiers received large sums of money.
