On February 10, 1258 a Mongol army sacked Baghdad, capital city of the Abbasid Caliphate. Shortly after, the Khan ordered the death of the last Abbasid Caliph, Al-Musta’sim. Though hardly remembered, it was an event that rocked the Muslim world in its days; the repercussions of which are still felt today.
Hulagu Khan, commander of the Mongols in the Middle East and founder of the Persia-based Il-Khanate, was the grandson of Genghis Khan and brother to both China’s Kublai Khan, and to another Kha-Khan (“Great Khan”, the title carried by the overlord of the entire Mongol Empire), Khan Möngke. At its peak, the realm Hulago created included Iran, Iraq, Kurdistan; and parts of Turkey, Syria, and Jordan.
The sack of Baghdad culminated the initial phase of the Mongol attempt to conquer the Middle East; begun with Genghis Khan’s conquest of Khwarezmia in 1221. A project abandoned after Genghis Khan’s death, his grandson took up the task; supported by perhaps the largest Mongol army ever assembled: by order of his brother, Great Khan Möngke, two-tenths of the empire’s fighting men were allocated to the task. Not less than 100,000 fighting men formed Hulago’s horde; and likely many more than that.
Hulago opened the campaign by attacking Alamut; the chief stronghold of the feared Asasiyun (Assassins) . This fortress citadel, thought at the time to be impregnable, lay in the mountains of Iran, about 60 miles from modern Tehran. Seeing the “handwriting on the wall”, the Assassins surrendered on condition their lives were spared. But Alamut was destroyed, and with it the power of the Assassin cult, which had terrorized the Middle East since the 11th century.
The ruins of lofty Alamut. From here, the “Old Man of the Mountain”, leader of the Assassin cult, directed an army of dedicated killers throughout the Middle East for almost two centuries. Hulagu Khan destroyed the citadel on his way to the sack of Baghdad.
Baghdad was then the ancient seat of the Abbasid Caliphate; a secular and religious authority within Islam that dated back to the 8th century. Established after the overthrow of the original Caliphate of the Umayyads in 750, the first Abbasid Caliph (which title means “Successor” to Mohammed) had built Baghdad as his new capital. For centuries, Baghdad was the power-center of Islam in the world. Though secular power had since the 11th century rested in the hands of Turkish Sultans; the Caliph was still the ultimate religious authority within Islam. Though schismatic Caliphates had contested Abbasid authority from time-to-time in Spain, Morocco and Egypt, the Abbasid Caliphate in Baghdad was the oldest and most recognized throughout the world.

Baghdad at its height in the 11th century had claim to being one of (if not the) largest cities in the world; boasting a population of between 1.2 million and 2 million souls. The city had a uniquely Persian design and flavor: unlike in Greek and Roman engineering tradition, where cites are laid out in a rectangular grid, the Persians built cities in a circular pattern, all streets radiating out from a central hub. At the center of Baghdad was the Golden Gate Palace; residence of the caliph and center of his administration. Surmounting the building was a 39 meter-high green dome; one of the largest in the world in its days (18 meters higher than Jerusalem’s Dome of the Rock; though fully 15 meters less than the lofty dome of Hagia Sophia.In the face of imminent Mongol invasion, the foolish Caliph Al-Musta’sim took no steps to call upon allies, raise additional troops, or strengthen his capital. Hulago’s massive army reached Baghdad on January 29th….
