Al-Musta'in

Al-Musta'in (836 – 17 October 866) was the Abbasid Caliph from 862 to 866, during the "Anarchy at Samarra". After the death of previous Caliph, al-Muntasir (who had not appointed any successors), the Turkic military leaders held a council to select his successor. They were not willing to have al-Mu'tazz or his brothers; so they elected Ahmad ibn Muhammad (أحمد بن محمد), a grandson of al-Mu'tasim, who took the regnal name Al-Mustaʿin bi-llah (المستعين بالله "he who looks for help to God").
