Ibn Fuladh, in order to gain Qazvin as his fief, revolted against the Buyid ruler Majd al-Dawla in 1016.
Majd al-Dawla, however, refused to make him governor of Qazvin, which made Ibn Fuladh threaten him around the countryside of his capital in Ray.
[1] Majd al-Dawla then requested the aid of his vassal, the Bavandid ruler Abu Ja'far Muhammad, who managed to defeat Ibn Fuladh and repel him from Ray.
[1] Ibn Fuladh then requested aid from the Ziyarid ruler Manuchihr, who was a rival of the Buyids.
Ibn Fuladh agreed to become Manuchihr's vassal in return for his aid.
