In this episode of the Umayyad Caliphate, we continue our exploration of Caliph Hisham ibn Abdul Malik’s reign as the Umayyad Caliphate faces mounting crises across its vast empire.

The year is 110 AH (728 CE), and the empire’s edges are on fire.

In the Caucasus, Maslamah ibn Abdul Malik leads a grueling campaign against the Khazar Khaganate through the treacherous Darial Pass. Despite claiming victory, his retreat is chaotic, marked by ambushes, torrential rain, and widespread exhaustion. Meanwhile, cracks appear in the empire’s eastern front. In Khurasan, a well-intentioned tax policy by Governor Ashras unleashes a wave of conversions among non-Arab Muslims—but when the policy is reversed, these new converts revolt. Their rebellion draws in the powerful Turgesh Khaganate, sparking a devastating loss for the Umayyads at the Battle of Baykand and the bloody Siege of Karmajah.

We also examine the collapse of Muslim authority in India, the chaotic military campaigns in Anatolia led by Hisham’s sons, and the shocking fall of Ardabil to the Khazars—a disaster that results in the death of a Muslim governor and the capture of tens of thousands of civilians.

As we move through these events, we see a common theme: a once-dominant caliphate now overstretched, undermanned, and increasingly reactive. The Muslim armies are no longer conquering; they’re fighting to survive. Strategic missteps, overreliance on loyalist Syrian troops, and a refusal to adapt military policy are setting the stage for further instability.

This episode paints a grim but necessary portrait of an empire entering a period of sustained decline. From Armenia to Transoxiana, we witness the human cost of imperial overreach—and the resilience of those left to defend a collapsing frontier.
