Capital: Baghdad
🪑 Accession and Early Rule
- Al-Musta’sim ascended the throne in 1242 CE, following the death of his father, Al-Mustansir.
- His reign came at a time when the Abbasid Caliphate was no longer the dominant political force in the Muslim world.
- The caliphate had already lost most of its territories and power, with much of the political control in the hands of regional rulers and military leaders.
⚔️ Weakness and Challenges
- Al-Musta’sim’s rule was marked by significant weakness and instability. The caliphate had no substantial military or political power, and the Abbasid caliph was reduced to a symbolic figurehead.
- Internal political strife and economic difficulties also characterized his reign. The Abbasid military had lost much of its effectiveness, and regional rulers often ignored the caliph’s authority.
- The caliph faced growing tensions with powerful neighbors, especially the Mongols, who were expanding across the Islamic world.
🌍 Relations with the Mongols
- The Mongol Empire, under Hulagu Khan (a grandson of Genghis Khan), was rapidly expanding during Al-Musta’sim’s reign.
- The Mongols had already sacked large parts of the Islamic world, including Persia and parts of the Levant, and their attention turned to Baghdad.
- Despite numerous warnings and diplomatic efforts to avoid conflict, Al-Musta’sim failed to form an effective defense against the Mongols, largely due to internal division and a lack of military resources.
⚔️ The Fall of Baghdad (1258 CE)
- In 1258 CE, Hulagu Khan’s forces laid siege to Baghdad, the capital of the Abbasid Caliphate.
- Al-Musta’sim was unable to defend the city effectively. The Mongols broke through the city’s walls, and after a brief resistance, Baghdad fell to them.
- The Mongol sack of Baghdad was a catastrophic event in Islamic history:
- The House of Wisdom, Baghdad’s great intellectual center, was destroyed.
- Thousands of scholars, scientists, and civilians were massacred.
- The city was looted, and its libraries, mosques, and buildings were severely damaged.
- Al-Musta’sim himself was captured by the Mongols.
🪦 Death and Aftermath
- After the fall of Baghdad, Al-Musta’sim was executed by Hulagu Khan. According to various sources, he was either executed by being wrapped in a rug and trampled by horses or suffocated.
- His death marked the end of the Abbasid Caliphate in Baghdad, after more than 500 years of Abbasid rule.
- The Mongols’ conquest of Baghdad was a defining moment in history, as the caliphate lost its religious and political authority, and the Mongol Empire expanded its reach into the heart of the Islamic world.
- Though the Abbasid Caliphate had already lost most of its territories, Baghdad’s fall was symbolic, ending the caliphate’s political existence.

His failure to defend the city from the Mongol siege led to the destruction of Baghdad and the execution of the caliph himself.
