ブワイフ朝
From 961 to 1015, the Ḥasanwayhid dynasty ruled over western Iran under the influence of the Buyid Dynasty. Centred at Dinawar, near present-day Kermanshah, Hasanwyhids, Kurdish Muslims with ties to the Kurdish Barzikani tribe, controlled central areas of the Zagros Mountains. At its greatest extent, the dynasty included the modern-day areas around Khorramabad, Borujerd, Nahavand, Asadabad, Borujerd, Ahwaz, Ilam, Kermanshah, Hulwan and Kirkuk. The Ḥasanwayhid dynasty was overthrown by the Annazids, who, with help of the Buyid dynasty, controlled the area until their collapse in 1116 CE.
