The moment in context
The western campaign opened against the Nizari Ismaili strongholds, called the Assassins in hostile sources, whose castles Mongol engineers reduced until Alamut surrendered in 1256. Hülegü then demanded Baghdad’s submission, and Caliph al-Musta‘sim refused while failing to prepare any effective defence, so the city fell in February 1258. The massacre and destruction ended the Abbasid caliphate in Baghdad and gravely damaged the city and its canal country. The story that the Tigris ran black with the ink of ruined books is literary memory rather than measurable evidence, and the human and institutional catastrophe needs no such legend to be understood.

Then ask the room: Ain Jalut is often called the battle that saved Islam — and often called overrated, since Hülegü had already left with the main army. Weigh both claims. The argued answer is on the chapter page →
