 Throughout the Buwayhid reign the Caliphate was at its lowest ebb, but was recognized religiously, except in Iberia.Buwayhid Sultan Mu'izz al-Dawla was prevented from raising a Shi'a Caliph to the throne by fear for his own safety, and fear of rebellion, in the capital and beyond.The next Caliph, Al-Ta'i, reigned over factional strife in Syria among the Fatimids, Turks, and Carmathians.
