The Late Baghdad Abbasids reigned from the beginning of the Crusades to the Seventh Crusade. The first Caliph was Al-Mustazhir. He was politically irrelevant, despite civil strife at home and the First Crusade in Syria. Raymond IV of Toulouse attempted to attack Baghdad, losing at the Battle of Manzikert. The global Muslim population climbed to about 5 per cent as against the Christian population of 11 per cent by 1100. Jerusalem was captured by crusaders who massacred its inhabitants. Preachers travelled throughout the caliphate proclaiming the tragedy and rousing men to recover the Al-Aqsa Mosque from the "Franks" (European Crusaders). Crowds of exiles rallied for war against the infidel. Neither the Sultan nor the Caliph sent an army west.
