In 1260, Hulagu Khan's Mongol army swept through Syria, culminating in the brutal six-day siege of Aleppo. This episode follows the campaign from the fall of Mayyafariqin to the sack of Aleppo and the destruction of the Great Mosque's minbar. Lucas and Luna discuss the Mongol alliance with the Armenian king Hethum I and the Crusader Bohemond VI, the use of trebuchets and naphtha, and the fate of the Ayyubid ruler al-Nasir Yusuf. They explore how the Mongol advance was halted by the Mamluk victory at Ain Jalut, a turning point that saved Egypt and Islam. The conversation also touches on the legacy of Aleppo's destruction, including the loss of the minbar that had been commissioned by Nur al-Din Zengi.
