Diya' al-Daula

Diya' al-Daula was the Buyid ruler of Basra during the 980s. He was the son of 'Adud al-Daula.

History

Following 'Adud al-Daula's death in 983, his possessions were divided between his sons. Samsam al-Daula, who was the presumed successor of 'Adud al-Daula, took power, but Sharaf al-Daula took advantage of his position in Kerman to invade Fars. This invasion distracted Samsam al-Daula and gave Diya' al-Daula the ability to set up his own independent rule in Basra.

Diya' al-Daula, as well as another brother, Taj al-Daula, who controlled Khuzestan, eventually decided acknowledge the authority of Fakhr al-Daula, who ruled in Jibal. This was done in an attempt to protect themselves from the conflict between Samsam al-Daula and Sharaf al-Daula; Basra and Khuzestan were situated in between the possessions of the two and were therefore vulnerable. Nevertheless, after a few years Sharaf al-Daula invaded and occupied Basra and Khuzestan, causing the two princes to flee to Fakhr al-Daula's territory. There they found refuge in Ray. Neither of the two brothers managed to found any lasting line; consequently their role in Buyid politics was short.
