Izz al-Dawla also had financial problems; in 973 he invaded the Amirate of Mosul, against the advice his father had left him. The campaign was a disaster; the Hamdanids under Abu Taghlib marched on Baghdad, while Sebük-Tegin was probably secretly supporting them. The Buyid amir then tried to solve his financial difficulties by seizing the Turkish fiefs, most of which were in Khuzestan. At the same time, he dismissed Sebük-Tegin from his post. The Turk revolted, forcing Izz al-Dawla to entrench himself in Wasit. He rejected Sebük-Tegin's offer to relinquish Baghdad in exchange for southern Iraq. The Turk then marched on Wasit, and laid siege to the city.
