Abu Mansur Fulad Sutun
Abu Mansur Fulad Sutun was the last Buyid amir of Fars, ruling more or less continuously from 1048 until his death. He was the son of Abu Kalijar.
Struggle for power
After the death of Abu Kalijar in 1048, his eldest son Abu Nasr Khusrau Firuz succeeded him as senior amir in Baghdad and assumed the title "al-Malik al-Rahim." Abu Mansur, however, rose up against his brother and took control of Fars. Al-Malik al-Rahim along with his brother Abu Sa'd Khusrau Shah invaded Fars and occupied Shiraz, also capturing Abu Mansur during the invasion. However, turmoil between the Turks and Daylamites in his army forced them to abandon the province and leave it in the hands of Abu Mansur. Abu Mansur then became the ruler of Fars once again, and captured parts of Ahvaz from Al-Malik al-Rahim. Al-Malik al-Rahim, however, managed to recapture Ahvaz and seize another town named Askar Mukram from Abu Mansur.
Seljuq suzerainty
In December 1055 al-Malik al-Rahim was arrested and deposed by Toghrul Beg's forces in Baghdad, bringing an end to Buyid rule in Iraq. Abu Mansur, who once again acknowledged Seljuk authority, however, was able to remain in power in Fars for another seven years as a Seljuk vassal. Constant fighting with his brothers, however, weakened his rule, and in 1062 he was killed while fighting against the Shabankara tribal chief Fadluya. The Seljuks shortly afterward entered Shiraz and took control of Fars.
