The power of the Buyid dynasty, though…
July 979 CE
The power of the Buyid dynasty, though it is to be subsequently fragmented among family members and provinces, is consolidated briefly during the reign of 'Adud ad-Dawlah, who by 977 had established himself as sole ruler, adding Oman, Tabaristan, and Jorjan to the original domains.
The Buyid state is now at its peak; it engages in public works, building hospitals and the Band-e amir (Emir's Dam) across the Kur River near Shiraz; it has relations with the Samanids, Hamdanids, Fatimids, and Constantinople; it patronizes artists, notably the poets al-Mutanabbi and Ferdowsi.
The Shi'i nature of the state is manifest in the inauguration of popular and passionate observance of Shi'i festivals and the encouragement of pilgrimages to the holy places of an-Najaf and Karbala' in Iraq.
