"Abu Nasr Firuz Kharshadh (Arabic: أبو نصر فيروز خوارشاذ; died December 22, 1012), better known by his laqab of Baha al-Dawla (Arabic: بهاء الدوله, romanized: Bahaʾ al-Dawla, lit. 'Splendour of the State') 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." - (Wikipedia (en) 12.08.2021)
