🪑 Accession and Rule
- Al-Mustansir ascended the caliphate after the death of his father, Az-Zahir, in 1226 CE.
- He inherited a caliphate that had regained a degree of stability and prestige under his grandfather An-Nasir, though actual political power was increasingly limited.

🏛️ The Mustansiriya Madrasah
- Al-Mustansir is most famous for establishing the Mustansiriya Madrasah in 1233 CE.
- Located in Baghdad, it became one of the most prestigious centers of learning in the Islamic world.
- The institution taught all four Sunni madhhabs—Hanafi, Maliki, Shafi’i, and Hanbali—a remarkable show of Sunni unity.

- Baghdad saw a revival of art, architecture, and science, and was once again considered the intellectual capital of the Muslim world during his reign.
🌍 Political and Military Situation
- Although Al-Mustansir held religious prestige, real political power was in the hands of military commanders and regional rulers like the Ayyubids and Seljuks.
- The Abbasid army was modest, and the caliph relied on alliances and diplomacy to maintain the caliphate’s autonomy.
- The Mongols, under Genghis Khan, were rapidly expanding in Central Asia, though they had not yet reached Iraq during Al-Mustansir’s reign.
🤝 Diplomacy and Foreign Relations
- Al-Mustansir maintained peaceful diplomatic relations with neighboring Muslim states, including the Ayyubids of Egypt and Syria.

- He was succeeded by his son Al-Musta’sim, the last Abbasid caliph of Baghdad before its fall to the Mongols.
