Yazid II
In 722, caliph Yazid II sent warlord al-Djarrah al-Hakami to defend the fortress of Derbent. Historian Al-Tabari recounts the campaigns of al-Djarrah thus: "Arabs defeating Khazars in southern Dagestan moved to the mountains of Dagestan, overcame the resistance of the people of Khamzin and Gumik, and in punitive expeditions ransacked Kaitag and Tabasaran for refusal to accept their authority."
