Abu Ishaq Ibrahim ibn Jaʿfar al-Muqtadir () better known by his regnal title al-Muttaqi (908 – July 968, ) was the Abbasid Caliph in Baghdad from 940 to 944. His reign marked the start of the 'later Abbasid period' (940–1258). Biography Al-Muttaqi was the son of al-Muqtadir and his concubine named Khalub also known as Zuhra. She was a Greek, and was the mother of Ibrahim (the future Caliph al-Muttaqi). His full name was Ibrahim ibn Jaʿfar al-Muqtadir and his Abu Ishaq. Of such little importance the Caliphate had become by now that when the previous Caliph al-Radi died, Bajkam, amir al-umara (Amir of Amirs), contented himself with despatching to Baghdad his secretary, who assembled the chief men to elect a successor. The choice fell on the deceased Caliph's brother al-Muttaqi, who assumed the office after it had been some days vacant; and whose first act was to send a banner and dress of honor to Bajkam, a needless confirmation of his rank. Bajkam, before returning to Wasit, where he now held his court, went out on a hunting party, and met his death at the hands of a band of marauding Kurds. The Capital again became the scene of renewed anarchy. Muhammad ibn Ra'iq, Caliph's amīr al-umarāʾ, persuaded the Caliph to flee with him to Mosul. Al-Muttaqi was welcomed there by the Hamdanid dynasty, who organized a campaign to restore him to the capital. However, their ends were purely selfish; they assassinated Ibn Ra'iq, and having added his Syrian government to their own, turned their ambition towards Baghdad. The Hamdanid chief, with the title of Nasir al-Dawla, advanced on Baghdad with the Caliph. But, however powerful the Hamdanid chiefs were at home amongst their Arab brethren, and splendid their victories over the Greeks, they found it a different thing to rule at Baghdad, due to foreign mercenaries and the well-organised Turkish forces in the city. And so in less than a year, the Hamdanid chieftains had to return to Mosul; for a Turkish general called Tuzun entered Baghdad in triumph, and was saluted as amir al-umara. However, fresh proceedings against his enemy obliged Tuzun to quit the capital; and during his absence a conspiracy broke out which placed the Caliph in danger, and obliged him again to appeal to the Hamdanid prince for help. Troops sent in response enabled him to escape; he fled to Mosul and after that
