[1] Unable to establish his rule in the province, Wahusdan returned to Tarum; Justan was recognized as ruler in Azerbaijan, with his brother Ibrahim made governor of Dvin.
Justan seems to have been interested primarily in his harem, a fact which alienated some of his supporters, although he and Ibrahim successfully put down a revolt by a grandson of the caliph al-Muktafi in 960.
Ibrahim raised an army in Armenia to oppose Isma'il, prompting Wahsudan to execute Justan, his mother and Nasir.
Rukn al-Dawla sent an army under his vizier Abu 'l-Fadl ibn al-'Amid to reinstate Ibrahim in Azerbaijan, and Wahsudan was ejected from Tarum for a time.
The successor of Ibrahim, Marzuban II ibn Ismail, managed to retain a small portion of Azerbaijan until 984 when he was captured by the Rawadids.
