'Imran died in the summer of 979, and was succeeded by his son [[Hasan ibn 'Imran|Hasan]]. The Buyid amir [['Adud al-DaulaDawla]] decided to use this as an opportunity to subjugate the Batihah. The army was commanded by the amir's vizier, [[Mutahhar]]. He attempted to dam the waterways, and create a raised road to allow his troops to approach Hasan's fortress on foot. The campaign cost a large amount of money, and it effectively stopped any trade boats from travelingtravelling the [[Tigris]]. Hasan, like his father, managed to stop Mutahhar by breaching the dams. The vizier tried to draw him out into open battle, but was unsuccessful. His failure in the campaign, as well as his fear of 'Adud al-DaulaDawla's wrath, eventually caused Mutahhar to commit suicide. 'Adud therefore called for an end to fighting, and all he gained was a money payment from Hasan.
Shortly after this, Hasan's brother Muhammad succeeded him. In 983 or 984, Muhammad was killed, bringing an end to the power of 'Imran's family. The man responsible for his murder, the Chamberlainchamberlain [[Muzaffar ibn 'Ali]], then assumed power. He died in 986 and was succeeded by his sister's son [[Abu 'l-Hasan 'Ali ibn Nasr]]. During this time, the Batihah rulers maintained good relations with the Buyids; neither 'Adud al-DaulaDawla or his successor [[Samsam al-DaulaDawla]] (983) launched any further expeditions against the swamp.
