Plausibility Check on one of the Caliphates (Abbasid or Ottomans) surviving to the present day as a primarily religious state, similar to the Papal States or the Vatican. Also threw in the possibly of a new Caliphate under the Saudis.
Some possible POD's:
1258 - Mongols sack Baghdad, but capture the Abbasid Caliph to keep as a figurehead, rather than outright killing him. The Ilkhanate uses the Caliph to keep the loyalty of their largely Islamic populace. Once the Ilkhanate collapses mid-1300's, various Middle Eastern powers fight to liberate/control the Caliph, as gaining the Caliphs allegiance is seen as a why to legalize their rule over the Islamic World. The Caliph bounces around as a puppet of the great powers (Timurids, Mamluks, Ottomans), but retaining limited autonomy (more over spiritual, rather than secular affairs), eventually becoming independent following the collapse of the Ottomans, similar to OTL.
1517 - Selim I conquers the Mamluks of Egypt who control the Abbasid Caliph, but instead of claiming the Caliphate for the Ottoman dynasty, he returns the Caliph to Mecca to rule over the Hejaz as a puppet ruler, lending legitimacy to the Ottoman Empire. Ottoman's collapse similar to OTL after WWI, but the Caliph declares independence rather than going down with the Turks, leading a small theocratic state in the Hejaz and Arabia.
1918 - Same as above, only with the Ottoman dynasty abandoning Turkey to rule Mecca/Medina as a Caliph.
1932 - After uniting the majority of Arabia under the House of Saud, the King of Saudi Arabia adopts the title of Caliph. The theocratic state has largely mixed relations with Western Powers, but lends support to the Allies during WWII, and later serves as the beacon for Pan-Islamist movement, contrary to Nasser's Pan-Arabism.
How would a modern Caliphate be looked at by the Western World, and how far reaching would a Caliph's authority be over Islam?
