The rise of the Buyid dynasty in Iran's political arenahad long-lasting influences on the political and intellectual developments of the Islamic world. The Buyids faced numerous threats for stabilizing their authority during the Abbasid Caliphate and the Al-Ziarat. One of the Buyids’ strategies for confronting these threats was forming alliances with regional powerful clans. Brydyans were one of the most powerful Iranian and Shiite families that ruled over Ahwaz, Basra, and Wasit. They were also seeking allies to consolidate their influence. So they allied with the Buyids against Abbasid Caliphate.Upon this allegiance, the Buyids obtained sufficient information about Baghdad. So they became a serious competitor of the Abbasid Caliphate. The decline of the Brydyan prepared the ground for the Buyids to strengthen their military capabilities and to move towards Baghdad. In light of such experiences, they could conquer Baghdad, on the one hand, and continue their dominance, on the other hand.
