Hulagu Khan, the grandson of Genghis Khan and the founder of the Ilkhanate in Persia, died in 1265. His death is often attributed to natural causes rather than assassination or murder. There isn’t a widely accepted historical narrative suggesting that he was killed by any individual or group.
It is important to note that during his reign, Hulagu Khan was responsible for the brutal conquest of Baghdad in 1258, which led to the fall of the Abbasid Caliphate. However, his death came many years later, after a relatively prosperous rule.
