4. The Last Caliph
Al Musta’sim Billah (1213 -1258) was the last ruler of the Abbasid Caliphate, and Islam’s last Caliph. A weak ruler ruling a weak rump of what had once been a mighty empire, Al Musta’sim was surrounded by ineffectual advisors who offered conflicting advice when the Mongols demanded his submission. He rejected the demands, ignoring some and answering others with bluster and empty threats, but failed to prepare adequate defenses against what was sure to follow such rejection.
The Mongols first erupted into the Islamic world in the 1220s, when Genghis Khan destroyed the Khwarezmian Empire and conquered as far west as western Persia up to the edges of Mesopotamia. That outburst was followed by a decades-long relative lull, as far as the Middle East and the Islamic world were concerned. During that stretch, the Mongols directed their energies elsewhere, against China, Kievan Rus, Eastern Europe, and in internal squabbles amongst themselves.
