Al-Muqtadi

Al-Muqtadi "(1056 – February 1094)" (Arabic: المقتدي 'the follower') was the Abbasid caliph in Baghdad from 1075 to 1094. He succeeded his grandfather caliph al-Qa'im in 1075 as the twenty-seventh Abbasid Caliph.
Biography.
He was born to Muhammad Dhakirat, the son of caliph Al-Qa'im, and an Armenian slave girl.
He was honored by the Seljuk sultan Malik-Shah I, during whose reign the Caliphate was recognized throughout the extending range of Seljuk conquest. Arabia, with the Holy Cities, now recovered from the Fatimids, acknowledged again the spiritual jurisdiction of the Abbasids. 
Malik-Shah I arranged a marriage between his daughter and al-Muqtadi, possibly planning on the birth of a son who could serve as both caliph and sultan. Though the couple had a son, the mother left with her infant to the court of Isfahan.
Following the failure of the marriage, the Sultan grew critical of the Caliph's interference in affairs of state, and sent an order for him to retire to Basra. The death of Malik-Shah I shortly after, however, made the command inoperative.
