'Adud al-Dawla
At its greatest extent, the Buyid dynasty encompassed territory of most of today's Iran, Iraq, Kuwait, and Syria, along with parts of Oman, the UAE, Turkey, Afghanistan and Pakistan. During the 10th and 11th centuries, shortly before the invasion of the Seljuq Turks, and particularly under king 'Adud al-Dawla, the Buyids were the most powerful and influential dynasty in the Middle East.
