Caliph al-Mustakfi is blinded and deposed by Mu'izz al-Dawla, ruler of the Buyid Empire. He is succeeded by al-Muti as caliph of the Abbasid Caliphate.

Abu al-Qasim Abd Allah ibn Ali, commonly known by his regnal name al-Mustakfi, was the Abbasid caliph in Baghdad from 944 to 946.

Ahmad ibn Buya, after 945 better known by his laqab of Mu'izz al-Dawla, was the first of the Buyid emirs of Iraq, ruling from 945 until his death.

The Buyid dynasty or Buyid Empire was a Zaydi and later Twelver Shi'a dynasty of Daylamite origin. Founded by Imad al-Dawla, they mainly ruled over central and southern Iran and Iraq from 934 to 1062. Coupled with the rise of other Iranian dynasties in the region, the approximate century of Buyid rule represents the period in Iranian history sometimes called the Iranian Intermezzo.

Abū ʾl-Qāsim al-Faḍl ibn al-Muqtadir, better known by his regnal name of al-Mutīʿ li-ʾllāh, was the Abbasid caliph in Baghdad from 946 to 974, ruling under the tutelage of the Buyid emirs.

The Abbasid Caliphate or Abbasid Empire was the third caliphate to succeed the Islamic prophet Muhammad. It was founded by a dynasty descended from Muhammad's uncle, Abbas ibn Abd al-Muttalib, from whom the dynasty takes its name. After overthrowing the Umayyad Caliphate in the Abbasid Revolution of 750 CE (132 AH), they ruled as caliphs based in modern-day Iraq, with Baghdad being their capital for most of their history.
