Baha' al-Dawla

Abu Nasr Firuz Kharshadh, better known by his laqab of Baha al-Dawla was the Buyid amir of Iraq (988–1012), along with Fars and Kerman (998–1012). His early reign was dominated by struggles with his rival relatives over control of the western Persian provinces, but by 998 he managed to establish his supremacy over the Buyid confederation. His reign nevertheless saw the increasing encroachment of neighbouring powers on Buyid territory, and marks the beginning of the decline of the Buyids' power. He was the third son of 'Adud al-Dawla.
