'Adud al-Dawla
Abu'l-Husain was the son of Adud al-Dawla and a daughter of Manadhar, who was a Justanid king. Following 'Adud al-Dawla's death in 983, his possessions were divided between his sons. Samsam al-Dawla, who was the presumed successor of 'Adud al-Dawla, took power, but Sharaf al-Dawla took advantage of his position in Kerman to invade Fars. This invasion provided Abu'l-Husain with the opportunity to set up his rule in Ahvaz, and took the title of "Taj al-Dawla".
