'Adud al-Dawla
In 974 Rukn al-Dawla sent 'Adud al-Dawla to suppress a large revolt against 'Izz al-Dawla, who had succeeded Mu'izz al-Dawla in Iraq in 967. 'Izz al-Dawla had also recognized Rukn al-Dawla as senior amir, but he and 'Adud al-Dawla had a dislike of each other. 'Adud al-Dawla successfully destroyed the rebellion, but ended up deposing his cousin as well and proclaimed himself the ruler of Iraq. Rukn al-Dawla, however, vehemently protested this, claiming that the line of Mu'izz al-Dawla could not be removed from power. 'Adud al-Dawla's offer to his father to pay tribute for his possession of Iraq was rejected, and he reluctantly reinstated 'Izz al-Dawla and returned to Fars.
